Abstract
Background: After experiencing symptoms for an average of 7 years before diagnosis, patients with endometriosis are usually left with more questions than answers about managing their symptoms in the absence of a cure. To help women with endometriosis after their diagnosis, we developed a digital program combining user research, evidence-based medicine, and clinical expertise. Structured around cognitive behavioral therapy and the quality of life metrics from the Endometriosis Health Profile score, the program was designed to guide participants for 3 months.
Objective: This cohort study was designed to measure the impact of a digital health program on the symptoms and quality of life levels of women with endometriosis.
Methods: In total, 63% (92/146) of the participants were included in the pilot study, recruited either free of charge through employer health insurance or via individual direct access. A control group of 404 women with endometriosis who did not follow the program, recruited through social media and mailing campaigns, was sampled (n=149, 36.9%) according to initial pain levels to ensure a similar pain profile to participants. Questionnaires assessing quality of life and symptom levels were emailed to both groups at baseline and 3 months. Descriptive statistics and statistical tests were used to analyze intragroup and intergroup differences, with Cohen d measuring effect sizes for significant results.
Results: Over 3 months, participants showed substantial improvements in global symptom burden, general pain level, anxiety, depression, dysmenorrhea, dysuria, chronic fatigue, neuropathic pain, and endo belly. These improvements were significantly different from the control group for global symptom burden (participants: mean –0.7, SD 1.6; controls: mean –0.3, SD 1.3; P=.048; small effect size), anxiety (participants: mean –1.1, SD 2.8; controls: mean 0.2, SD 2.5; P<.001; medium effect size), depression (participants: mean –0.9, SD 2.5; controls: mean 0.0, SD 3.1; P=.04; small effect size), neuropathic pain (participants: mean –1.0, SD 2.7; controls: mean –0.1, SD 2.6; P=.004; small effect size), and endo belly (participants: mean –0.9, SD 2.5; controls: mean –0.3, SD 2.4; P=.03; small effect size). Participants’ quality of life improved between baseline and 3 months and significantly differed from that of the control group for the core part of the Endometriosis Health Profile-5 (participants: mean –5.9, SD 21.0; controls: mean 1.0, SD 14.8; P=.03; small effect size) and the EQ-5D (participants: mean 0.1, SD 0.1; controls: mean –0.0, SD 0.1; P=.001; medium effect size). Perceived knowledge of endometriosis was significantly greater at 3 months among participants compared to the control group (P<.001).
Conclusions: This study’s results suggest that a digital health program providing medical and scientific information about endometriosis and multidisciplinary self-management tools may be useful to reduce global symptom burden, anxiety, depression, neuropathic pain, and endo belly while improving knowledge on endometriosis and quality of life among participants.

Introduction
Background
Endometriosis is a chronic, inflammatory disease affecting an estimated 1 in 10 women of childbearing age. It is defined by the presence of endometrial-like tissue outside the uterine cavity [Zondervan KT, Becker CM, Missmer SA. Endometriosis. N Engl J Med. Mar 26, 2020;382(13):1244-1256. [CrossRef] [Medline]1]. Manifestations of the disease are mainly painful (eg, dysmenorrhea, dyspareunia, dyschezia, and dysuria), with symptoms substantially impacting the quality of life (QOL) of those affected [Della Corte L, Di Filippo C, Gabrielli O, Reppuccia S, La Rosa VL, Ragusa R, et al. The burden of endometriosis on women's lifespan: a narrative overview on quality of life and psychosocial wellbeing. Int J Environ Res Public Health. Jun 29, 2020;17(13):4683. [FREE Full text] [CrossRef] [Medline]2]. There is no definitive cure, and available solutions aim to reduce symptoms. The initial solutions are generally hormonal, which are not always well tolerated by patients [Zondervan KT, Becker CM, Missmer SA. Endometriosis. N Engl J Med. Mar 26, 2020;382(13):1244-1256. [CrossRef] [Medline]1], consistent with their fertility goals, or effective in relieving pain [O'Hara R, Rowe H, Fisher J, O'Hara R, Rowe H, Fisher J. Managing endometriosis: a cross-sectional survey of women in Australia. J Psychosom Obstet Gynaecol. Sep 2022;43(3):265-272. [FREE Full text] [CrossRef] [Medline]3]. While surgery was once widely recommended to patients with endometriosis, given the frequent disease recurrence [Ceccaroni M, Bounous VE, Clarizia R, Mautone D, Mabrouk M. Recurrent endometriosis: a battle against an unknown enemy. Eur J Contracept Reprod Health Care. Dec 25, 2019;24(6):464-474. [CrossRef] [Medline]4], it is now increasingly restricted to selected patients for whom it can be relevant in European countries [Becker CM, Bokor A, Heikinheimo O, Horne A, Jansen F, Kiesel L, et al. ESHRE Endometriosis Guideline Group. ESHRE guideline: endometriosis. Hum Reprod Open. 2022;2022(2):hoac009. [FREE Full text] [CrossRef] [Medline]5]. Thus, living with endometriosis means learning to deal with the symptoms, using tools other than or in complement to hormonal therapy. After experiencing symptoms for an average of 7 years before diagnosis [Nnoaham KE, Hummelshoj L, Webster P, d'Hooghe T, de Cicco Nardone F, de Cicco Nardone C, et al. World Endometriosis Research Foundation Global Study of Women's Health consortium. Impact of endometriosis on quality of life and work productivity: a multicenter study across ten countries. Fertil Steril. Aug 2011;96(2):366-73.e8. [FREE Full text] [CrossRef] [Medline]6], the lack of an adapted care pathway for symptom management is a crucial unmet need of the patients [Giudice LC, Horne AW, Missmer SA. Time for global health policy and research leaders to prioritize endometriosis. Nat Commun. Dec 04, 2023;14(1):8028. [FREE Full text] [CrossRef] [Medline]7]. Various nonpharmacological interventions have been studied to help with symptom management, such as dietary changes, physical activity, sex therapy, and mind-body interventions, which seem pertinent for the daily management of endometriosis [Armour M, Sinclair J, Chalmers KJ, Smith CA.

Digital tools may offer a solution to enhance accessibility to and observance of nonpharmacological interventions toward endometriosis symptom reduction.
Prior Work
Developing a program to improve QOL requires the construction of content corresponding to what can modulate the QOL of women with endometriosis. Numerous studies to assess changes in patients’ QOL have been using the Endometriosis Health Profile (EHP) score as a reference for almost 20 years [Jones GL, Budds K, Taylor F, Musson D, Raymer J, Churchman D, et al. A systematic review to determine use of the Endometriosis Health Profiles to measure quality of life outcomes in women with endometriosis. Hum Reprod Update. Mar 01, 2024;30(2):186-214. [FREE Full text] [CrossRef] [Medline]13]. The EHP is a standardized tool for measuring QOL. Initially developed with 30 items (EHP-30) [Jones G, Jenkinson C, Kennedy S. Evaluating the responsiveness of the endometriosis health profile questionnaire: the EHP-30. Qual Life Res. Apr 2004;13(3):705-713. [CrossRef]14], a shortened version with 5 items (ie, EHP-5) was also validated [Jones G, Jenkinson C, Kennedy S. Development of the short form endometriosis health profile questionnaire: the EHP-5. Qual Life Res. Apr 2004;13(3):695-704. [CrossRef]15]. The following EHP components were taken into account in developing the programs: pain, control and powerlessness, emotional well-being, social support, self-image, work life, infertility and children management, sexual relationships, and relation to the medical profession.
Cognitive behavioral therapy (CBT) is a well-supported treatment for various disorders [Hofmann SG, Asnaani A, Vonk IJ, Sawyer AT, Fang A. The efficacy of cognitive behavioral therapy: a review of meta-analyses. Cognit Ther Res. Oct 01, 2012;36(5):427-440. [FREE Full text] [CrossRef] [Medline]16]. CBT’s goal is to help individuals better understand the relationship and interaction between their emotions, cognitions (received ideas), and behavior to be able to manage their symptoms and quit the vicious cycle that contributing factors may create through behavior change (develop coping mechanisms), cognitive restructuring (restructure maladaptive thoughts), and emotion regulation (relaxation and acceptance) [Butler AC, Chapman JE, Forman EM, Beck AT. The empirical status of cognitive-behavioral therapy: a review of meta-analyses. Clin Psychol Rev. Jan 2006;26(1):17-31. [CrossRef] [Medline]17-DiGiuseppe R, Venezia R, Gotterbarn R. What is cognitive behavior therapy? In: Vernon A, Doyle KA, editors. Cognitive Behavior Therapies: A Guidebook for Practitioners. New York, NY. American Counseling Association; 2018:1-35.19]. It was found to improve the QOL for patients with chronic pain conditions [Ehde DM, Dillworth TM, Turner JA. Cognitive-behavioral therapy for individuals with chronic pain: efficacy, innovations, and directions for research. Am Psychol. 2014;69(2):153-166. [CrossRef] [Medline]20-de C Williams AC, Eccleston C, Morley S. Psychological therapies for the management of chronic pain (excluding headache) in adults. Cochrane Database Syst Rev.

Specific and general therapeutic mechanisms in cognitive behavioral treatment of chronic pain. J Consult Clin Psychol. Feb 2015;83(1):1-11. [CrossRef] [Medline]24]. Internet-based CBT programs have been proven effective for a variety of disorders [Andersson G, Carlbring P. Internet-assisted cognitive behavioral therapy. Psychiatr Clin North Am.

Cognitive behavioral therapy for chronic pain in veterans: evidence for clinical effectiveness in a model program. Psychol Serv. Feb 2022;19(1):95-102. [FREE Full text] [CrossRef] [Medline]30], the following components are found: psychoeducation on pain mechanisms and biopsychosocial model, goal settings, CBT-based behavior skills for managing pain (eg, pleasant activities and sleep hygiene), emotion regulation and mind-body interventions (eg, relaxation methods and mindfulness), cognitive restructuring, and long-term action plan for maintenance and anticipation of obstacles.
Goal of This Study
A digital solution for endometriosis symptom management was developed using a CBT approach based on EHP items. The digital support solution focused on the scientific and medical state of the art around 5 nonpharmacological interventions (disease education including pain mechanism, diet, adapted physical activity, well-being and mental health, and sexual health). The School of Endo digital program was developed and made available in France to help women with endometriosis after their diagnosis.
This cohort study was designed to measure the impact of a digital health program on the symptoms and QOL levels of women with endometriosis. The study also aimed to provide insights into the value of a digital program for the day-to-day management of endometriosis and to address the lack of real-life data studies for digital support in endometriosis.
Methods
Development of a Digital Health Program
To develop a digital health program that adequately addresses the needs of patients with endometriosis, several steps were followed, where product development and scientific research complemented each other [Craig P, Dieppe P, Macintyre S, Michie S, Nazareth I, Petticrew M, et al. Medical Research Council Guidance. Developing and evaluating complex interventions: the new Medical Research Council guidance. BMJ. Sep 29, 2008;337(sep29 1):a1655. [FREE Full text] [CrossRef] [Medline]31]. As the first step, 120 semistructured interviews and >100 web-based questionnaires with patients and health professionals were conducted to understand the needs of women with endometriosis. According to this user research, the primary need expressed by women with endometriosis was to find help with the daily management of symptoms, especially pain. A small exploratory preliminary program was developed and tested by women to complement the user research. A scientific rationale and advice from medical experts completed the user research. User research, evidence-based medicine, and clinical expertise were combined to enable the development of the program [Koninckx PR, Ussia A, Gordts S, Keckstein J, Saridogan E, Malzoni M, et al. The 10 "cardinal sins" in the clinical diagnosis and treatment of endometriosis: a Bayesian approach. J Clin Med. Jul 07, 2023;12(13):4547. [FREE Full text] [CrossRef] [Medline]32].
The structure of the program’s content was based on CBT and the QOL items of the EHP score, and participants were advised to follow it for 3 months. The program was accessible from November 2022 for women with endometriosis aged >18 years, either at no fee through employer health insurance (Mutuelle Générale de l’Education Nationale) or individual direct payment. Program participants were invited to join the pilot study on a voluntary basis.
This program sought to provide evidence-based information and tools to empower patients on symptom management through a wide range of content: videos, exercises, written content, live sessions, quizzes, and a community-based platform. A total of 12 endometriosis experts were involved in the construction of the program, constituting a multidisciplinary team.
Scientific rationale highlighted some factors of interest for the program. In an Australian study on 484 women with endometriosis, dietary changes were reported among the most effective strategies in terms of reducing self-reported pain associated with the disease [Armour M, Sinclair J, Chalmers KJ, Smith CA. Self-management strategies amongst Australian women with endometriosis: a national online survey. BMC Complement Altern Med. Jan 15, 2019;19(1):17. [FREE Full text] [CrossRef] [Medline]8]. Optimizing nutrition is a nonpharmacological intervention that can be used to manage the symptoms of endometriosis. The positive effects of physical activity have been documented for various health conditions, including mental health (improved cognitive function, enhanced QOL, improved sleep, and reduced signs of anxiety and depression) and chronic pain [Mińko A, Turoń-Skrzypińska A, Rył A, Bargiel P, Hilicka Z, Michalczyk K, et al.

According to current research, psychological interventions and mind-body approaches are promising for improving QOL and alleviating pain, anxiety, depression, stress, and fatigue in women with endometriosis [Evans S, Fernandez S, Olive L, Payne LA, Mikocka-Walus A. Psychological and mind-body interventions for endometriosis: a systematic review. J Psychosom Res. Sep 2019;124:109756. [CrossRef] [Medline]9,Hansen KE, Brandsborg B, Kesmodel US, Forman A, Kold M, Pristed R, et al.

[FREE Full text] [CrossRef] [Medline]10]. The impact of endometriosis on sex life harms patients’ self-esteem. Sex therapy and psychological interventions can be very beneficial during treatment to improve QOL [Facchin F, Buggio L, Dridi D, Barbara G, Vercellini P. The subjective experience of dyspareunia in women with endometriosis: a systematic review with narrative synthesis of qualitative research. Int J Environ Res Public Health. Nov 18, 2021;18(22):12112. [FREE Full text] [CrossRef] [Medline]11].
The program addressed every aspect of the disease through 5 sections: disease education including pain mechanism, diet, adapted physical activity, well-being and mental health, and sexual health. It started with a section on knowledge of the disease, with an introduction to the program and the multidisciplinary approach. Psychoeducation was focused on defining the disorder, its causes, and its impacts. It helped the participant generate a model of their disorder and pain to obtain a representation of a functional analysis of the factors perpetuating the symptoms. The first part of the program concluded with educating the participants on setting goals and initiating change and provided tools to help them set their goals.
CBT content is included throughout the program. Each section mentioned subsequently contains education, advice, and tools created by health care professionals in the field.
The diet section covered step-by-step behavior change through good mealtime habits, from breakfast to dinner, with the help of calendars to fill in. This section provided information on why and how to make dietary changes with endometriosis, particularly on the role of diet in inflammation and digestive symptoms. A section dedicated to identifying inflammatory foods was also available to participants.
The sections dedicated to physical activity presented different ways to stay active while experiencing symptoms and suggested various methods, including yoga, Pilates, physiotherapy exercises, and daily habits, to move the body. A 30-minute yoga session and a Pilates session were available each week. These sessions focused mainly on pelvic mobility. Physiotherapy complemented the physical activity with ventral breathing exercises and a focus on the perineum and abdominal muscles.
The mental health section focused mainly on education and prevention to help with emotional regulation. Relaxation practices, sophrology exercises, Beck columns, and a weekly diary to initiate behavior changes were proposed.
The sexuality and intimacy section featured physiotherapy exercises, sex therapy tools, and advice to rediscover pleasure and self-confidence in sexual relations.
The program allowed participants to create their toolbox and action plan. Section contents were delivered weekly for 3 months and were available for a further 3 months (Figure 1).

Ethical Considerations
A study protocol was established in compliance with French regulations, reviewed by the Lyv Healthcare company’s ethics committee, and filed with the French public structure for studies on health data: Health Data Hub (N° F20221114165253). Participants answered the questionnaires on a voluntary basis after being informed about the research project objectives and were provided with contact information to exercise their rights. At any time, participants had the possibility to opt out. All collected data were pseudonymized and stored in compliance with health data security standards (Health Data Hosting certification, hébergeurs de données de santé). No personal information was shared with third parties, and all data analysis was performed on deidentified datasets. No compensation was provided to either program participants or the control group for their participation in the study.
Impact of the Digital Health Program
Questionnaires
Our study compared 2 groups, distinct in terms of exposure to the digital program, both having participants with endometriosis. The study is considered a cohort study because the allocation of respondents to the exposure criterion was not controlled for the research participant, and there was no prospective assignment. Two web-based questionnaires were sent to program participants via email links and reminders on the program’s community-based platform. The first questionnaire was sent at the time of inclusion in the program (time point 0 [T0]) and the second one after 3 months (T0+3 mo), with 2 weeks to submit their answers. Participants completed the questionnaires on their own, requiring approximately 15 minutes to complete. Questionnaires were structured into 2 parts, including a main part (53 questions) and a bonus part (24 questions), explaining differences in the sample size for some outcomes. Both questionnaires were electronically tested before diffusion. A back button allowed respondents to review and modify their answers, while IP addresses were used to ensure that each participant was a unique visitor, with only the first submission used for analysis.
Population Sample
Women were free to choose whether to take part in the program, with no obligation to complete it in full. Program participants were given the freedom to answer the questionnaires. This pilot study included participants who completed the main part entirely at baseline and 3 months.
Only women who reported being diagnosed with endometriosis could answer the questionnaires. The diagnosis could be clinical, imagery based, or surgical. To record the effect of active use of the program on participants, the threshold of following at least half of the proposed content types was retained. As a result, among the participants, only women who declared having tested >50% of the proposed content type in the program were included.
The terms woman and women are used in this paper. It should be noted that people with a uterus may or may not identify with these terms and experience endometriosis. Sex and gender were not criteria for inclusion in the study.
Control Group
A control group of women with endometriosis who did not follow the program was recruited via social media and a health insurance provider email campaign (Mutuelle Générale de l’Education Nationale). The women in the control group were volunteers, motivated solely by the desire to contribute to advancing research, as no incentives, prizes, or rewards were offered for their participation. The control group received the same questionnaires as program participants during the same periods to eliminate external effects on measured parameters.
The control group was sampled on the initial pain level to have a similar profile between them and program participants. Women were selected from the control group by stratifying the sample to reproduce the distribution of pain levels among program participants. QOL answers were not selected for this stratification as these questions were part of bonus questionnaires. A random sample of women from the control group was selected so that the same proportion was represented for each modality of the participants’ general pain level. The proportional sample was thus selected, reducing the number of women in the control group to 149.
Study Outcomes Measures
Numeric Rating Scales
Numeric Rating Scales (NRSs) are 11-point scales, ranging from 0 (no pain or symptom) to 10 (intense pain or symptom), primarily used to measure symptom intensity. NRS evaluated the level of overall pain, anxiety, depression, dysmenorrhea, dyspareunia, dyschezia, dysuria, chronic pelvic pain, gastrointestinal disorders, chronic fatigue, neuropathic pain, and endo belly. Endo belly is a common term used by patients with endometriosis to describe the cyclic bloating of the abdomen [Velho RV, Werner F, Mechsner S. Endo belly: what is it and why does it happen?: a narrative review. J Clin Med. Nov 19, 2023;12(22):7176. [FREE Full text] [CrossRef] [Medline]35] as “uncomfortable or painful, often accompanied by a sensation of abdominal fullness,” and which “often forces women with endometriosis to wear loose clothing” [Luscombe GM, Markham R, Judio M, Grigoriu A, Fraser IS. Abdominal bloating: an under-recognized endometriosis symptom. J Obstet Gynaecol Can. Dec 2009;31(12):1159-1171. [CrossRef] [Medline]36]. Endo belly affects >80% of women with gastrointestinal symptoms due to endometriosis [Maroun P, Cooper MJ, Reid GD, Keirse MJ. Relevance of gastrointestinal symptoms in endometriosis. Aust N Z J Obstet Gynaecol. Aug 2009;49(4):411-414. [CrossRef] [Medline]37].
Women without menstruation did not respond to the dysmenorrhea NRS, and women without sexual activities did not respond to the dyspareunia NRS, which explains differences in sample size for these outcomes.
An average of each of these NRSs was used to determine a global symptom burden score, ranging from 0 to 10.
EHP-5 Scale
EHP-5 is a QOL scale specific to endometriosis. A main score is calculated out of 100 (100=poor QOL and 0=good QOL), based on 5 items with 5 modalities (scored as 0, 25, 50, 75, and 100). The main score is the average of the scores for the 5 items. A modular score is calculated out of 100 (100=worst QOL and 0=best QOL), based on 6 optional 5-modality items (scored as 0, 25, 50, 75, and 100). The score is the average of the scores for the 6 items.
EQ-5D Scale
EQ-5D is a QOL scale nonspecific to endometriosis. It comprises 5 items with 5 modalities scored from 1 to 5. The concatenation of the 5 scores gives a combination. Each combination ranging from 11111 to 55555 has a numerical equivalent between –0.53 and 1. EQ-5D score ranges from –0.53 (poor QOL) to 1 (good QOL).
Statistical Analysis
Symptoms were considered to have evolved (improved or deteriorated) if scores had changed by >2 points compared with T0 [Pokrzywinski RM, Soliman AM, Snabes MC, Chen J, Taylor HS, Coyne KS. Responsiveness and thresholds for clinically meaningful changes in worst pain numerical rating scale for dysmenorrhea and nonmenstrual pelvic pain in women with moderate to severe endometriosis. Fertil Steril. Feb 2021;115(2):423-430. [FREE Full text] [CrossRef] [Medline]38]. QOL was considered to have evolved (improved or deteriorated) if the score had changed by >15% compared with T0 [Aubry G, Panel P, Thiollier G, Huchon C, Fauconnier A. Measuring health-related quality of life in women with endometriosis: comparing the clinimetric properties of the Endometriosis Health Profile-5 (EHP-5) and the EuroQol-5D (EQ-5D). Hum Reprod. Jun 01, 2017;32(6):1258-1269. [CrossRef] [Medline]39]. Otherwise, outcomes were considered stable.
The minimum sample size was calculated through a feasibility study power analysis for outcomes between program participants and the control group. This feasibility study was carried out on a preliminary program among 55 participants to identify ways to improve the program and observe symptoms and QOL levels. Global pain on the NRS was assumed by a mean (SD) of 5.9 (2.3). Assuming a difference of at least 2 points, a power (1–β) of 0.80, α=.05, and using a 2-sided 2-sample test, 11 program participants and 11 participants from the control group would be required to detect group differences. QOL was measured on the EHP-5, assumed by a mean (SD) of 53.6 (19.0). Assuming a change in score of at least 15%, a power of 0.80, α=.05, and using a 2-sided 2-sample test, 13 program participants and 13 participants from the control group would be required for detecting between-group differences. On the basis of power analyses, it was planned to include answers from at least 13 program participants and 13 from the control group.
Descriptive statistics were carried out (number of participants, percentage, mean, and SD). Statistical tests used to measure the significance of intragroup evolution were the chi-square test and the Fisher exact test for discrete variables, the Wilcoxon signed rank test for paired and nonparametric continuous variables, and the paired 2-tailed Student t test for parametric continuous variables. Statistical tests used to measure between-group differences (participants vs controls) were the chi-square test and the Fisher exact test for discrete variables, the Mann-Whitney U test for unpaired and nonparametric continuous variables, and the unpaired 2-tailed Student t test for parametric continuous variables. Furthermore, we applied the Benjamini-Hochberg method to adjust for multiple comparisons. This method controls the false discovery rate, offering a balance between minimizing false positives and maintaining statistical power. Cohen d tests were performed to measure effect size when the result was statistically significant. If Cohen d>|0.2|, the effect size was considered small, medium if Cohen d>|0.5|, and large if Cohen d>|0.8|. Each outcome was studied separately. A sensitivity analysis was conducted to note the impact of program follow-up according to baseline QOL level. For this, linear regression models and interaction tests were used with the EHP-5 core QOL level (good QOL: 0 to 32, medium QOL: 33 to 65, and low QOL: 66 to 100). Statistical analysis was performed with SAS software (version 9.4; SAS Institute).
Results
Population Description
The pilot study was based on the responses to the main questionnaire part from 92 program participants diagnosed with endometriosis and 149 women diagnosed with endometriosis who did not follow the program, constituting the control group (Figure 2).

Respondents to the questionnaires took part in this study on a voluntary basis. Distribution of symptom levels and quality of life for endometriosis program participants at baseline.Table 1 presents the characteristics of the program participants and those of the control group at baseline. On average, participants were aged 36.7 (SD 6.8) years and were diagnosed with the disease when they were aged 32.5 (SD 6.7) years. In total, 26% (24/92) of the participants were experiencing or had experienced infertility problems. There were no substantial differences in socioeconomic characteristics or pain levels at the time of inclusion compared to the control group. Participants had a slightly poorer QOL at the time of inclusion than those in the control group (P=.04) and were more often on a continuous hormonal pill (P=.046).

Impact on Endometriosis Symptoms
Initially, the participants’ most severe symptom was chronic fatigue (mean 7.5, SD 2.1), followed by dysmenorrhea (mean 7.3, SD 1.8) and anxiety (mean 6.5, SD 2.2; Table 2).
Overall, there was a tendency for all symptoms to improve during the 3 months of following the program (Table 3). For some symptoms, the evolution was not significant compared with the control group: dyspareunia, dyschezia, chronic pelvic pain, gastrointestinal disorders, overall pain, dysuria, and chronic fatigue. Over 3 months, the global symptom burden, general level of pain, anxiety, depression, dysmenorrhea, dysuria, chronic fatigue, neuropathic pain, and endo belly improved significantly for the program participants. These improvements were significantly different compared to the control group for global symptom burden (P=.048; small effect size), anxiety (P<.001; medium effect size), depression (P=.04; small effect size), neuropathic pain (P=.004; small effect size), and endo belly (P=.03; small effect size).

When looking at symptom evolution (improvement, stability, or deterioration), the distribution was not significantly different between the 2 groups for dyspareunia, dyschezia, dysuria, chronic pelvic pain, gastrointestinal disorders, and chronic fatigue (Table 4). Global symptom burden improved in 20% (18/90) of the program participants versus 6.1% (9/147) in the control group (P=.003). Anxiety levels improved in 42% (38/90) and deteriorated in 11% (10/90) of the program participants versus 26.5% and 28.6%, respectively, in the control group (P=.002). Depression deteriorated less in program participants (9/89, 10%) than in the control group (41/147, 27.9%; P=.003). Neuropathic pain improved more in program participants (37/90, 41%) than in the control group (34/147, 23.1%; P=.02), as did endo belly (37/90, 41% vs 36/147, 24.5%; P=.03).
Actively following the digital program for 3 months was associated with a significant improvement in global symptom burden, anxiety, depression, neuropathic pain, and endo belly perception among program participants when compared to the control group.

Impact on QOL
With all 3 scores used (EHP-5 core part, EHP-5 modular part, and EQ-5D), active program participants showed an improvement in their QOL after 3 months on the program (Table 2). This evolution observed between 0 and 3 months significantly differed from the control group for the core part of the EHP-5 (P=.03; small effect size) and the EQ-5D (P=.001; medium effect size;
Table 3). Therefore, the use of the program was associated with an improvement of QOL in participants with endometriosis.
When looking at the types of evolution (improvement, stability, or deterioration) in QOL, an improvement of the EQ-5D and the EHP-5 core part was observed in 2 and 3 times more women in the program participants than in the control group, respectively (Table 5). However, the difference in the types of evolution was not significant between the 2 groups for EQ-5D (P=.58) and the core part of EHP-5 (P=.07). A significant difference in the types of evolution between the 2 groups was observed for the modular part of the EHP-5 (P=.02), with an improvement in 31% (12/39) of the program participants versus 11% (7/64) of the controls.

To better understand these evolutions in QOL, we focused on the items that make up the QOL scores (Table 6). There was a significant difference at baseline (P=.03; small effect size) in the core part of the EHP-5 score on the item concerning control and powerlessness. Program participants were more affected than those in the control group. This significant difference disappeared at 3 months. Besides, after 3 months, there was a significant improvement in the sexual relationship item (P=.02; small effect size) in the modular part of the EHP-5 score, which was not observed in the control group. Participants were less often worried about pain during sexual intercourse after 3 months on the program than before starting the program. Finally, the usual activity item in the EQ-5D score improved nearly significantly for the program participants (P=.05; small effect size) after 3 months, which was not the case in the control group, with participants feeling less limited in their usual activities after 3 months on the program.
The benefits of a digital program also depend on how it is used; in this study, it was found that the greater the frequency of use or the greater the diversity of sections consulted, the greater the improvement in symptoms or QOL (Multimedia Appendices 2 and O'Hara R, Rowe H, Fisher J, O'Hara R, Rowe H, Fisher J. Managing endometriosis: a cross-sectional survey of women in Australia. J Psychosom Obstet Gynaecol. Sep 2022;43(3):265-272. [FREE Full text] [CrossRef] [Medline]3). The results did not show any statistically significant correlations between the viewing of action-oriented content and the program’s effectiveness ( The evolution of outcomes between baseline and 3 months for all endometriosis program participants according to the sections thresholds of the program tested.Multimedia Appendix 3

Impact on Perceived Knowledge of Endometriosis
Initially, there was no significant difference in perceived knowledge between program participants and the control group (P=.74; Table 7). In total, 22% (20/92) of the program participants felt that they knew little about the disease, 71% (65/92) had good knowledge, and 8% (7/92) considered themselves experts (vs 34/149, 22.8%; 99/149, 66.4%; and 16/149, 10.7%, respectively for the control group). At 3 months, none of the program participants considered themselves as knowing little about the disease (0/92, 0%); 64% (59/92) considered themselves as having good knowledge, and 36% (33/92) considered themselves experts (vs 25/149, 16.8%; 104/149, 69.8%, and 20/149, 13.4%, respectively, for the control group). The perceived knowledge of endometriosis was significantly different at 3 months between the 2 groups (P<.001;
Table 5). As expected, the program seemed to improve perceived knowledge of endometriosis.

Multiple Comparisons and Sensitivity Analysis
To address the potential for type I errors due to multiple testing in this pilot analysis, we applied the Benjamini-Hochberg method to adjust significance thresholds while maintaining statistical power. This approach controls the false discovery rate and is particularly suited for exploratory analyses.
Beta coefficients and 95% CIs of nonadjusted linear regression models evaluating associations between endometriosis program participation and health outcomes and interaction tests according to baseline quality of life levels (Endometriosis Health Profile-5 core part).Table 1 illustrates that the QOL levels, as assessed by the EHP-5 core part, significantly differed between the 2 groups at baseline (P=.04). However, the proportion of participants reporting poor QOL was similar in both groups (P=.15). To explore the potential influence of these baseline differences on the evolution of outcomes, we conducted interaction analyses using linear regression models, as detailed in

Discussion
Principal Findings
This pilot study of 92 program participants and 149 individuals in the control group shows that following a 3-month digital health program for the self-management of endometriosis symptoms is associated with a significant reduction in endometriosis-related symptoms (anxiety, depression, neuropathic pain, and endo belly perception), a reduction of the global symptom burden, and a significant improvement in the participants’ knowledge of endometriosis. Furthermore, following the program seemed to be associated with an improvement in QOL. Combining CBT approaches and EHP-focused programs in a digital tool has proved useful in inducing symptom relief and a better QOL.
Comparison With Prior Work
Previous studies have shown that patients often use nonpharmacological interventions to cope with their symptoms [Armour M, Sinclair J, Chalmers KJ, Smith CA. Self-management strategies amongst Australian women with endometriosis: a national online survey. BMC Complement Altern Med. Jan 15, 2019;19(1):17. [FREE Full text] [CrossRef] [Medline]8,Gagnon MM, Brilz AR, Alberts NM, Gordon JL, Risling TL, Stinson JN. Understanding adolescents' experiences with menstrual pain to inform the user-centered design of a mindfulness-based app: mixed methods investigation study. JMIR Pediatr Parent. Apr 08, 2024;7:e54658. [FREE Full text] [CrossRef] [Medline]40]. However, only one short-term study has examined the value of combining these nonpharmacological interventions as part of a multidisciplinary approach for QOL with endometriosis [Rohloff N, Rothenhöfer M, Götz T, Schäfer SD. Observational pilot study on the influence of an app-based self-management program on the quality of life of women with endometriosis. Arch Gynecol Obstet. Aug 13, 2024;310(2):1157-1170. [CrossRef] [Medline]41], and a recent publication tested the application over 3 months [Rohloff N, Götz T, Kortekamp SS, Heinze NR, Weber C, Schäfer SD. Influence of app-based self-management on the quality of life of women with endometriosis. Cureus. Aug 2024;16(8):e67655. [CrossRef] [Medline]42]. Instead, most published studies analyzed the benefits of such interventions individually. These studies, among other things, have underpinned the development of our proposed program, which offers patients various tools and solutions to manage their symptoms.
As confirmed by our results, CBT has been found to be helpful in managing pain and improving the scores of depression and QOL in patients with endometriosis [Donatti L, Malvezzi H, de Azevedo BC, Baracat EC, Podgaec S. Cognitive behavioral therapy in endometriosis, psychological based intervention: a systematic review. Rev Bras Ginecol Obstet. Mar 16, 2022;44(3):295-303. [FREE Full text] [CrossRef] [Medline]43-Wu S, Wang X, Liu H, Zheng W. Efficacy of cognitive behavioral therapy after the surgical treatment of women with endometriosis: a preliminary case-control study. Medicine (Baltimore). Dec 23, 2022;101(51):e32433. [FREE Full text] [CrossRef] [Medline]45]. New studies are also beginning to be conducted on the benefits of psychological and relaxation interventions for patients with endometriosis, thus far demonstrating improvement in pain [Jafari H, Courtois I, Van den Bergh O, Vlaeyen JW, Van Diest I. Pain and respiration: a systematic review. Pain. Jun 2017;158(6):995-1006. [CrossRef] [Medline]46], stress [Petit E, Lhuillery D, Loriau J, Sauvanet E. Endométriose: Diagnostic et Prise en Charge. Paris. Elsevier-Masson, Pratique en Gynécologie-Obstétrique; 2020. 47], anxiety, depression, and QOL [Zhao L, Wu H, Zhou X, Wang Q, Zhu W, Chen J. Effects of progressive muscular relaxation training on anxiety, depression and quality of life of endometriosis patients under gonadotrophin-releasing hormone agonist therapy. Eur J Obstet Gynecol Reprod Biol. Jun 2012;162(2):211-215. [CrossRef] [Medline]48,Samami E, Shahhosseini Z, Khani S, Elyasi F. Pain-focused psychological interventions in women with endometriosis: a systematic review. Neuropsychopharmacol Rep. Sep 27, 2023;43(3):310-319. [FREE Full text] [CrossRef] [Medline]49]. The improvement of mental health–related symptoms in our results might be in part due to the psychological and relaxation approaches included in our program. Given the link between mental health and QOL in women with endometriosis [Pontoppidan K, Olovsson M, Grundström H. Clinical factors associated with quality of life among women with endometriosis: a cross-sectional study. BMC Womens Health. Oct 24, 2023;23(1):551. [FREE Full text] [CrossRef] [Medline]50], future research should explore the use of more comprehensive scales for anxiety and depression. Furthermore, nutrition and physical activity have been studied separately and proved to have an impact on endometriosis symptoms, stress, anxiety, and QOL [Cirillo M, Argento FR, Becatti M, Fiorillo C, Coccia ME, Fatini C. Mediterranean diet and oxidative stress: a relationship with pain perception in endometriosis. Int J Mol Sci. Sep 27, 2023;24(19):14601. [FREE Full text] [CrossRef] [Medline]51-Posadzki P, Ernst E, Terry R, Lee MS. Is yoga effective for pain? A systematic review of randomized clinical trials. Complement Ther Med. Oct 2011;19(5):281-287. [CrossRef] [Medline]56]. Finally, although sexual issues are a prevalent symptom, sex education for women with endometriosis has only been assessed in one study, where an improvement in sexual function and quality of sexual life was observed [Matloobi M, Amini L, Shahali S, Haghani H, Tahermanesh K, Hassanlouei B, et al. Effect of sex education on sexual function and sexual quality of life in women with endometriosis: a quasi-experimental study. Int J Gynaecol Obstet. Dec 25, 2022;159(3):702-710. [CrossRef] [Medline]57]. Interestingly, in our study, the EHP-5 score for the sexual intercourse apprehension item decreased for participants, notwithstanding persisting dyspareunia. This highlights a change in the perception of sexual anxiety after 3 months, despite the persistence of pain. Digital programs for the management of endometriosis should study the long-term effect of sex education content on dyspareunia, both in terms of symptoms and perception.
While the efficacy and relevance of each intervention for the management of endometriosis symptoms have thus been confirmed by previous research, a multidisciplinary approach is in line with current guidelines; therefore, it should be encouraged for women with endometriosis and more generally for those who experience chronic pain [Armour M, Avery J, Leonardi M, Van Niekerk L, Druitt ML, Parker MA, et al. Lessons from implementing the Australian National Action Plan for Endometriosis. Reprod Fertil. Jul 01, 2022;3(3):C29-C39. [FREE Full text] [CrossRef] [Medline]58,Endometriosis: diagnosis and management. National Institute for Health and Care Excellence. URL: https://www.nice.org.uk/guidance/ng73 [accessed 2024-04-29] 59]. Future studies should seek to determine the optimal combination of nonpharmacological interventions according to patient profiles to find the right balance between diet, physical activity, stress management, sleep, and environmental enrichment on top of their medical care [Wattier JM. Antalgiques et alternatives thérapeutiques non médicamenteuses pluridisciplinaires. Gynecol Obstet Fertil Senol. Mar 2018;46(3):248-255. [CrossRef] [Medline]60,De Hoyos G, Ramos-Sostre D, Torres-Reverón A, Barros-Cartagena B, López-Rodríguez V, Nieves-Vázquez C, et al. Efficacy of an environmental enrichment intervention for endometriosis: a pilot study. Front Psychol. Oct 10, 2023;14:1225790. [FREE Full text] [CrossRef] [Medline]61].
In terms of methodology, our study assessed each symptom using numerical scales to simplify user responses and limit attrition rates. For QOL, we used 2 different scales: the EQ-5D, which is nonspecific to endometriosis, and the EHP-5, which is specific to endometriosis. These were previously compared in a French study [Aubry G, Panel P, Thiollier G, Huchon C, Fauconnier A. Measuring health-related quality of life in women with endometriosis: comparing the clinimetric properties of the Endometriosis Health Profile-5 (EHP-5) and the EuroQol-5D (EQ-5D). Hum Reprod. Jun 01, 2017;32(6):1258-1269. [CrossRef] [Medline]39], which concluded that while both scales were appropriate for assessing the QOL of women with endometriosis, the EHP-5 was better at assessing health-related QOL, especially regarding medical treatment and the intensity of dysmenorrhea. According to our results, the EHP-5 does seem to better discriminate with regard to endometriosis, which echoes the conclusions of the French study [Aubry G, Panel P, Thiollier G, Huchon C, Fauconnier A. Measuring health-related quality of life in women with endometriosis: comparing the clinimetric properties of the Endometriosis Health Profile-5 (EHP-5) and the EuroQol-5D (EQ-5D). Hum Reprod. Jun 01, 2017;32(6):1258-1269. [CrossRef] [Medline]39]. However, regardless of the scale used, following our digital program was associated with an improved QOL. This was true for 2 to 3 times more participants than individuals in the control group. Our study used a 15% threshold to define a change in QOL, allowing stringent evolutions to be highlighted. Program participants had a poorer QOL level at baseline compared to the control group (despite a similar pain profile). However, after 3 months of following the program, program participants caught up with the QOL level of the control group.
Digital tools are a way to bring multidisciplinary interventions to patients, enhancing their accessibility. Studies on digital interventions for various conditions have shown positive results, such as improvements in anxiety and depression through CBT-based approaches [Verkleij M, Georgiopoulos AM, Barendrecht H, Friedman D. Pilot of a therapist-guided digital mental health intervention (eHealth CF-CBT) for adults with cystic fibrosis. Pediatr Pulmonol. Jul 05, 2023;58(7):2094-2103. [CrossRef] [Medline]62], symptom management and QOL enhancements via mindfulness-based stress-reduction programs [Miazga E, Starkman H, Schroeder N, Nensi A, McCaffrey C. Virtual mindfulness-based therapy for the management of endometriosis chronic pelvic pain: a novel delivery platform to increase access to care. J Obstet Gynaecol Can. Jun 2024;46(6):102457. [FREE Full text] [CrossRef] [Medline]63], or better health outcomes through digital personalized diets [Jactel SN, Olson JM, Wolin KY, Brown J, Pathipati MP, Jagiella VJ, et al. Efficacy of a digital personalized elimination diet for the self-management of irritable bowel syndrome and comorbid irritable bowel syndrome and inflammatory bowel disease. Clin Transl Gastroenterol. Jan 01, 2023;14(1):e00545. [FREE Full text] [CrossRef] [Medline]64]. Similarly, multidisciplinary digital programs have demonstrated significant benefits across diverse chronic conditions, including improved QOL and symptom management. For instance, internet-based programs have been shown to enhance knowledge, increase exercise habits, and reduce heart failure symptoms [Tomita MR, Tsai BM, Fisher NM, Kumar NA, Wilding G, Stanton K, et al. Effects of multidisciplinary internet-based program on management of heart failure. J Multidiscip Healthc. Dec 01, 2008;2009(2):13-21. [FREE Full text] [CrossRef] [Medline]65], while personalized digital care programs have improved the QOL in adults with autoimmune diseases and post–COVID-19 condition [Bundy N, De Jesus M, Lytle M, Calabrese L, Gobin C, Dyhrberg M.

May 16, 2023;9(2):e003061. [FREE Full text] [CrossRef] [Medline]66]. Digital support programs have also improved self-reported QOL in patients with rheumatoid arthritis [Dobies B, White A, Isberg A, Gudmundsson S, Oddsson S. Digital health program improves quality of life in rheumatoid arthritis: a retrospective analysis of real-world data. Clin Exp Rheumatol. Jan 2024;42(1):10-14. [FREE Full text] [CrossRef] [Medline]67] and managing symptoms in patients with cancer [Gudmundsson GH, Mészáros J, Björnsdóttir ÁE, Ámundadóttir ML, Thorvardardottir GE, Magnusdottir E, et al. Evaluating the feasibility of a digital therapeutic program for patients with cancer during active treatment: pre-post interventional study. JMIR Form Res. Oct 13, 2022;6(10):e39764. [FREE Full text] [CrossRef] [Medline]68]. In our study, we observed that a digital tool using a CBT approach is effective in helping patients manage a condition, in this case, endometriosis. This may have to do with the fact that digital technology can bring about a different perception and thus reduce the stigma surrounding intimate issues associated with endometriosis, such as psychological or sexuality aspects [Stern E, Micoulaud Franchi JA, Dumas G, Moreira J, Mouchabac S, Maruani J, et al. How can digital mental health enhance psychiatry? Neuroscientist. Dec 04, 2023;29(6):681-693. [CrossRef] [Medline]28,Hollis C, Morriss R, Martin J, Amani S, Cotton R, Denis M, et al.

Developing an educational website for women with endometriosis-associated dyspareunia: usability and stigma analysis. JMIR Hum Factors. Mar 03, 2022;9(1):e31317. [FREE Full text] [CrossRef] [Medline]71]. These findings underscore the potential of multidisciplinary digital programs to relieve symptoms, improve QOL, and enhance disease-related knowledge across various chronic conditions.
For digital therapeutics to achieve their purpose, they must meet patient needs in terms of content while optimizing patient adherence and fulfilling prescriber requirements. The content of our program was based on EHP components to address subjects that were relevant to patients with endometriosis and was approved by health care specialists. Other studies have looked at digital technology for managing endometriosis or pelvic pain and highlighted the need for educational content, psychological and social support, and patient empowerment in particular [Gagnon MM, Brilz AR, Alberts NM, Gordon JL, Risling TL, Stinson JN. Understanding adolescents' experiences with menstrual pain to inform the user-centered design of a mindfulness-based app: mixed methods investigation study. JMIR Pediatr Parent. Apr 08, 2024;7:e54658. [FREE Full text] [CrossRef] [Medline]40]. As for patient adherence, to enhance digital therapeutic efficiency, it is crucial that future studies analyze specific factors influencing patient engagement in a digital program, such as trust, interactions, and consideration [Stern E, Breton Z, Alexaline M, Geoffroy PA, Bungener C. Redefining the relationship in digital care: a qualitative study of the Digital Therapeutic Alliance. Encephale (Forthcoming). May 08, 2024. [FREE Full text] [CrossRef] [Medline]72].
Keeping patients engaged to increase their frequency of use and guiding them through nonpharmacological, multidisciplinary interventions are therefore key to a program’s efficiency. Guidelines and studies encourage the multidisciplinary management of endometriosis. However, only 2 studies on the same intervention, evaluating the QOL after 2 and 12 weeks following a multimodal program, have been conducted in the context of digital intervention [Rohloff N, Rothenhöfer M, Götz T, Schäfer SD. Observational pilot study on the influence of an app-based self-management program on the quality of life of women with endometriosis. Arch Gynecol Obstet. Aug 13, 2024;310(2):1157-1170. [CrossRef] [Medline]41,Rohloff N, Götz T, Kortekamp SS, Heinze NR, Weber C, Schäfer SD. Influence of app-based self-management on the quality of life of women with endometriosis. Cureus. Aug 2024;16(8):e67655. [CrossRef] [Medline]42]. Our study contributes to answering the need for new research on the multidisciplinary management of endometriosis and the development of programs to make such management accessible [Agarwal SK, Antunez-Flores O, Foster WG, Hermes A, Golshan S, Soliman AM, et al.

[FREE Full text] [CrossRef] [Medline]74].
Limitations and Strengths
Our study is subject to several limitations. It is based on voluntary participation only, with no compulsory questionnaires and no obligation to complete the program. It also includes a selection bias, with no information as to whether the profiles of the women who answered the questionnaires were similar to the overall profiles of the women who took part in the program. Although the participants in this study was not randomized, differences between program participants and the control group were minimized by selecting a control group sample with pain levels similar to those of program participants (despite a different initial QOL level, the effect of which was analyzed in sensitivity analyses). Using the Benjamini-Hochberg method, we were able to control the false discovery rate. Nevertheless, we interpreted results with borderline P values cautiously, acknowledging the increased risk of type I errors inherent in multiple testing.
Furthermore, participants self-reported their diagnosis of endometriosis, which may be clinical, imaging based, or surgical. However, one can assume that women who do not have endometriosis would not attend the program and would not spend time filling in research questionnaires.
A strength of the program is that it was designed based on user research, scientific rationale, and medical expertise. Our approach, targeting EHP components and using CBT, allowed the development of an effective digital tool for the self-management of endometriosis symptoms. In addition, the use of 2 different questionnaires on QOL showed that following the program was associated with an improvement of the health-related QOL (EQ-5D) and the QOL specific to endometriosis (EHP-5). Very little amount of data exists on the reliability and efficiency of a digital program for the management of endometriosis symptoms. Our study is the first step in identifying key factors to be considered for developing a digital health program for the daily management of endometriosis and in demonstrating its positive impact on patient symptoms and QOL.
Conclusions
Our results suggest that a digital health program providing medical and scientific information about endometriosis as well as multidisciplinary self-management tools may be a helpful and effective resource for women to manage life with endometriosis alongside their medical care. Hence, a digital program for endometriosis that combines integrative solutions, focuses on EHP components, and uses a CBT approach can enhance patient care for those with endometriosis.
