In addition to combating social exclusion at the societal level, strengthening the coping abilities of young LGBTQ+ people is an important goal. Objective: In this transdiagnostic feasibility study, we tested a 6-week internet intervention program designed to increase the ability of nonclinical LGBTQ+ participants to cope with adverse events in their daily lives. The program was based on acceptance and commitment therapy principles. Methods: The program consists of 6 web-based modules and low-intensity assistance for homework provided by a single care provider asynchronously. The design was a single-group assignment of 15 self-identified LGB community members who agreed to participate in an open trial with a single group (pre- and postintervention design). Results: Before starting the program, participants found the intervention credible and expressed high satisfaction at the end of the intervention. Treatment adherence, operationalized by the percentage of completed homework assignments (32/36, 88%) was also high. When we compared participants’ pre- and postintervention scores, we found a significant decrease in clinical symptoms of depression (Cohen d=0.44, 90% CI 0.09-0.80), social phobia (d=0.39, 90% CI 0.07-0.72), and posttraumatic stress disorder (d=0.30, 90% CI 0.04-0.55). There was also a significant improvement in the level of self-acceptance and behavioral effectiveness (d=0.64, 90% CI 0.28-0.99) and a significant decrease in the tendency to avoid negative internal experiences (d=0.38, 90% CI 0.09-0.66). The level of general anxiety disorder (P=.11; d=0.29, 90% CI –0.10 to 0.68) and alcohol consumption (P=.35; d=–0.06, 90% CI –0.31 to 0.19) were the only 2 outcomes for which the results were not statistically significant. Conclusions: The proposed web-based acceptance and commitment therapy program, designed to help LGBTQ+ participants better manage emotional difficulties and become more resilient, represents a promising therapeutic tool. The program could be further tested with more participants to ensure its efficacy and effectiveness.
