          <title>Background</title>
          <p>Alcohol use disorder (AUD) is associated with severe chronic medical conditions and premature mortality. Expanding the reach or access to effective evidence-based treatments to help persons with AUD is a public health objective. Mobile phone or smartphone technology has the potential to increase the dissemination of clinical and behavioral interventions (mobile health interventions) that increase the initiation and maintenance of sobriety among individuals with AUD. Studies about how this group uses their mobile phone and their attitudes toward technology may have meaningful implications for participant engagement with these interventions.</p>

          <title>Methods</title>
          <p>A sample of 71 adults with AUD (mean age 42.9, SD 10.9 years) engaged in an alcohol partial hospitalization program completed 4 subscales from the Media Technology Usage and Attitudes assessment: <italic>Smartphone Usage</italic> measures various mobile phone behaviors and activities, <italic>Positive Attitudes</italic> and <italic>Negative Attitudes</italic> measure attitudes toward technology, and the <italic>Technological Anxiety/Dependence</italic> measure assesses level of anxiety when individuals are separated from their phone and dependence on this device. Participants also provided demographic information and completed the Epidemiologic Studies Depression Scale (CES-D) and the Generalized Anxiety Disorder (GAD-7) scale. Lastly, participants reported their frequency of alcohol use over the past 3 months using the Drug Use Frequency Scale.</p>

      <title>Introduction</title>
      <sec>
        <title>Background</title>
        <p>Many chronic health problems are associated with alcohol use disorder (AUD), including stroke, high blood pressure, heart disease, cancer of the esophagus, liver, and colon [<xref ref-type="bibr" rid="ref1">1</xref>-<xref ref-type="bibr" rid="ref3">3</xref>]. AUD is also related to a plethora of psychological and behavioral problems [<xref ref-type="bibr" rid="ref3">3</xref>]. According to the 2019 National Survey on Drug Use and Health, prevalence rates of AUD among US adults show that 14.1 million have this disorder [<xref ref-type="bibr" rid="ref4">4</xref>]. Approximately 88,000 people die annually from alcohol-related diseases [<xref ref-type="bibr" rid="ref4">4</xref>,<xref ref-type="bibr" rid="ref5">5</xref>], making it a significant public health concern. Accordingly, an objective of alcohol treatments is to help patients abstain from alcohol use.</p>
        <p>Long-term abstinence has been shown to improve various complications of alcohol-related diseases [<xref ref-type="bibr" rid="ref6">6</xref>]. Abstinence maintenance is intricately linked with the successful completion of the initial days following alcohol cessation, when individuals tend to experience elevated anxiety, depression, and cravings for alcohol and are thus at high risk for a relapse occurrence [<xref ref-type="bibr" rid="ref7">7</xref>,<xref ref-type="bibr" rid="ref8">8</xref>]. Patients at this stage tend to report low self-efficacy to effectively manage daily triggers for alcohol consumption [<xref ref-type="bibr" rid="ref9">9</xref>,<xref ref-type="bibr" rid="ref10">10</xref>]. Consequently, fundamental strategies to facilitate the acquisition of sobriety and long-term maintenance requires real-time interventions that provide individuals with ongoing support and the necessary skills to manage relapse risk factors [<xref ref-type="bibr" rid="ref9">9</xref>,<xref ref-type="bibr" rid="ref10">10</xref>]. Mobile phone technologies are among the recommended platforms to augment public health impact [<xref ref-type="bibr" rid="ref11">11</xref>,<xref ref-type="bibr" rid="ref12">12</xref>] and can be harnessed to increase reach and dissemination of multifaceted approaches designed to effectively address both cognitions and behaviors associated with AUD.</p>
        <p>The wide availability of mobile phone or smartphone ownership (97%) and frequent app usage (80% in the past 30 days) among US adults [<xref ref-type="bibr" rid="ref13">13</xref>,<xref ref-type="bibr" rid="ref14">14</xref>] provides an opportunity for researchers to reach this population at scale. Traditional face-to-face substance use intervention programs are inherently limited in their ability to assess and treat real-time risks that can occur in the individual's day-to-day environment [<xref ref-type="bibr" rid="ref11">11</xref>]. Moreover, low engagement and high attrition are common among traditional substance use treatment interventions with this population, particularly among patients in early recovery [<xref ref-type="bibr" rid="ref11">11</xref>,<xref ref-type="bibr" rid="ref15">15</xref>,<xref ref-type="bibr" rid="ref16">16</xref>]. Smartphone-delivered interventions have shown promising results in increasing engagement and improving outcomes with mental health and behavioral health treatments, although most mHealth studies lack any theoretical framework [<xref ref-type="bibr" rid="ref11">11</xref>,<xref ref-type="bibr" rid="ref17">17</xref>,<xref ref-type="bibr" rid="ref18">18</xref>]. For example, a recent review shows efficacy of mHealth alcohol use interventions, but results remain mixed overall [<xref ref-type="bibr" rid="ref11">11</xref>].</p>
        <p>According to Golbert et al [<xref ref-type="bibr" rid="ref11">11</xref>], strengthening the rigor of this emerging research requires applying theoretically informed approaches and the use of randomized controlled trials (RCTs) to adequately assess the effect of these new interventions [<xref ref-type="bibr" rid="ref11">11</xref>]. To our knowledge, there are 2 theory-informed, smartphone app delivered interventions for adults with AUD being conducted [<xref ref-type="bibr" rid="ref19">19</xref>,<xref ref-type="bibr" rid="ref20">20</xref>]. While these studies could help determine the efficacy of these technology-based approaches for improving alcohol use outcomes, essential to their success is an understanding of how individuals with AUD use their mobile phone in their daily lives and their attitudes toward technology, which may have an effect on participants' engagement with these interventions.</p>
        <p>Studies conducted with general populations have demonstrated variability in mobile use patterns across demographic subgroups (eg, men vs women, White vs non-White, and married vs single) [<xref ref-type="bibr" rid="ref21">21</xref>,<xref ref-type="bibr" rid="ref22">22</xref>]. Correspondingly, these findings have been used to inform the development of mHealth approaches addressing barriers and facilitators for behaviors that are more likely to appeal to particular groups [<xref ref-type="bibr" rid="ref21">21</xref>,<xref ref-type="bibr" rid="ref22">22</xref>]. Similar assessment studies with individuals with AUD may provide guidance for the development of mHealth intervention approaches in different subgroups of this population, such as those with higher levels of comorbid affective symptoms (eg, anxiety and depression). Because mHealth interventions with individuals with AUD is a developing research area, examining predictors of smartphone use and attitudes toward technology is an important step toward advancing this work.</p>

        <title>Objectives</title>
        <p>This study explores mobile use behaviors and attitudes toward technology among adults with AUD receiving outpatient treatment. In addition to demographic characteristics (eg, age, gender, and marital status), mental health factors (eg, anxiety and depression symptoms), which are highly relevant to this population [<xref ref-type="bibr" rid="ref23">23</xref>,<xref ref-type="bibr" rid="ref24">24</xref>], were also examined as potential correlates of mobile phone behaviors and attitudes toward technology. Moreover, a potential effect of the level of alcohol use on mobile phone behaviors and attitudes toward technology was explored.</p>

        <title>Participant Recruitment and Study Design</title>
        <p>Participants were recruited from an alcohol and drug partial hospitalization program at a private hospital in the Northeastern United States. This program provides an abstinence-based and cognitive-behavioral treatment. Patients attend 3-4 groups per day (eg, relapse prevention, drink, drug refusal skills, goal-setting, etc), daily individual counseling with a mental health worker, and medication management with an attending psychiatrist. Adult patients were approached by research staff to determine their interest in participating in a study designed to develop or test a 12-week smartphone app for increasing physical activity engagement among adults in early recovery from alcohol. Recruitment occurred in 2 phases: as part of an open pilot and then subsequently as part of a RCT. Data collected as part of the baseline assessment from each of these phases were examined in this paper.</p>

          <title>Media and Technology Usage and Attitudes (MTUA) Scale</title>
          <p>The MTUA is a 50-item scale with 15 subscales. In this study, we administered 4 subscales: <italic>Smartphone Usage</italic>, <italic>Positive Attitudes Toward Technology</italic>, <italic>Negative Attitudes Toward Technology</italic>, and <italic>Technological Anxiety/Dependence</italic>. Each subscale has been shown to have strong validity and reliability [<xref ref-type="bibr" rid="ref25">25</xref>]. The <italic>Smartphone Usage</italic> subscale consists of 7 items assessing the frequency, on a 10-point frequency, ranging from 1=never to 10=all of the time, of engaging in various smartphone activities (eg, texting, emailing, taking pictures). The other 3 subscales are measured based on a Likert-type scale, ranging from 1=strongly agree to 5=strongly disagree [<xref ref-type="bibr" rid="ref25">25</xref>] and assess different attitudes toward technology: (1) <italic>Positive Attitudes</italic> subscale (an item is “I feel I get more accomplished because of technology”), (2) <italic>Negative Attitudes</italic> subscale (an item is “new technology makes life more complicated”), and (3) <italic>Technological Anxiety/Dependence</italic> subscale measures anxiety that resulted from individuals being away from their phone (an item is “I get anxious when I don’t have my phone with me”).</p>

          <title>The Drug Use Frequency Scale</title>
          <p>The Drug Use Frequency Scale is a self-report instrument consisting of 10 items that measure the frequency of use for different substances over the past 3 months [<xref ref-type="bibr" rid="ref26">26</xref>]. Participants reported their frequency of alcohol use (and use of other substances) using a 7-point Likert-type scale ranging from 0=not all to 7=every day.

          <title>Overview</title>
          <p>Frequencies for the following demographic characteristics were examined in the combined data set from the 2 trials (open pilot and RCT): race, marital status, age, gender, ethnicity, education, employment, and income. There were missing data for variables (eg, employment, education, and income) not collected in the open pilot study.</p>

          <title>Sample Characteristics and Development of Subgroups</title>
          <p>Sample size constraints for the variables race and marital status allowed for comparison between being White and non-White and married/living with a partner vs single/divorced/widowed. For age, a median split approach was used to create 2 age groups: ≥43 years and ≤44 years. Less than 1% of the sample reported an ethnic identity, and hence group comparisons were not feasible. Employment status was coded into 2 groups: employed vs unemployed/retired/disabled. For education, the groups were high school/some college versus college degree/advanced degrees. Annual income was reported by 39 participants and was coded into 2 categories: ≤US $75,000 and ≥US $75,000.</p>
        </sec>
        <sec>
          <title>Preliminary Analyses</title>
          <p>Chi-square tests were used to explore potential proportion difference among race, gender, age (independent variables), and marital status, education, employment, and annual income (dependent variables). A series of ANOVA models evaluated mean differences for the abovementioned 7 demographics and the 3 dependent variables, GAD-7, CES-D, and alcohol use.</p>

        <sec>
          <title>Primary Analyses</title>
          <p>ANOVA evaluated demographic differences for each of the 4 MTUA subscales. Separate linear regression analyses were used to explore a potential association between anxiety (GAD-7) and depression (CES-D), alcohol use (independent variables), and each of the MTUA subscales (dependent variables). In addition to statistical significance, partial eta-squared (<italic>η</italic><sub>p</sub><sup>2</sup>), <italic>R</italic>, or <italic>R</italic><sup>2</sup> <italic>β</italic> values were used, as appropriate, to demonstrate the level of association between the independent variables and dependent measures [<xref ref-type="bibr" rid="ref29">29</xref>,<xref ref-type="bibr" rid="ref30">30</xref>].</p>

        <title>Sample Description</title>
        <p>The majority of participants identified as White (56/70, 80%), others identified as non-White (14/70, 20%), and over half of the participants were men (36/62, 58%). Nearly half of the sample was aged ≤43 years (30/61, 49%), while 51% (31/61) of participants were aged ≥44 years. Participant age range was 20-64 (mean 42.89, SD 10.9) years. Fifteen participants were married/living with a partner (15/40, 38%), and 25 (63%) were single/divorced/widowed. For education, 43% (17/40) of participants were in the high school/some college category, and 57% (23/40) were in the college degree/advanced degrees group. Moreover, 56% (27/48) of the sample was employed, and 12% (25/48) were unemployed/retired/disabled. Furthermore, 67% (24/39) of participants reported an annual income of ≤US $75,000, while 39% reported an annual income of ≥US $75,000. The distribution of alcohol use variables showed that 37% (26/71) of the sample reported consuming alcohol for “5-6 days a week” over the past 3 months. A higher number of participants (33/71, 47%) reported consuming alcohol “every day” over the past 3 months.</p>
        <p>There were no statistically significant differences for race, gender, age and marital status, education, employment, and annual income (<xref ref-type="table" rid="table1">Table 1</xref>).</p>
        <p>Moreover, there were no statistically significant relationships between the demographics and the GAD-7, CES-D, and alcohol use variables (see <xref ref-type="table" rid="table2">Table 2</xref>).</p>

        <title>Principal Findings</title>
        <p>This study provides an examination of mobile phone use behavioral patterns and attitudes toward technology among a sample of adults with alcohol use disorder (AUD) in early recovery. Demographics, anxiety and depressive symptoms, and alcohol use were associated with smartphone usage and attitudes toward technology. These results may provide insights into the development of mobile phone delivered intervention (mHealth) approaches for individuals with AUD.</p>
        <p>Relative to older patients with AUD, those aged ≤43 years reported higher rates of smartphone usage and were more likely to have positive attitudes about media use. Specifically, younger patients had greater reliance on their mobile phone to complete various tasks, such as using apps, searching for directions, and browsing the web and reported a more positive view of these activities. These results are consistent with previous studies demonstrating a strong association between being a younger age and greater reliance on this device to complete many daily tasks—aided by easy access to the internet—compared to older adults [<xref ref-type="bibr" rid="ref21">21</xref>,<xref ref-type="bibr" rid="ref22">22</xref>]. High usage of mobile apps has been shown to be associated with perceived importance in facilitating the accomplishment of targeted goals using these platforms [<xref ref-type="bibr" rid="ref21">21</xref>,<xref ref-type="bibr" rid="ref22">22</xref>].</p>
        <p>Therefore, this younger subgroup of patients may be very receptive to using a smartphone app to help during early recovery, and mHealth strategies consistent with how this group uses their phone are likely to be more acceptable and engaging. For example, a mobile phone app with a “resource” feature on AUD may provide a menu of information on the psychophysiological impact of this disorder, effective treatments, including strategies for managing risks for relapse, such as environmental triggers, depression, anxiety, and cravings [<xref ref-type="bibr" rid="ref1">1</xref>,<xref ref-type="bibr" rid="ref2">2</xref>,<xref ref-type="bibr" rid="ref4">4</xref>]. Given existing barriers to treatment and the impact of chronic alcohol use on long-term memory and cognitive functioning [<xref ref-type="bibr" rid="ref6">6</xref>], ready access to this information in moments of greatest need (eg, high-risk situations) may be critical toward improving alcohol treatment outcomes.</p>
        <p>Our findings also demonstrated that single/divorced/widowed participants indicated greater anxiety without their phone or feeling more dependent on this device than those who were married/living with a partner. A previous study assessing mobile phone use behaviors among a nonclinical population has shown overall similar results [<xref ref-type="bibr" rid="ref21">21</xref>]. It is possible that individuals with AUD who do not live with a partner are more likely to rely on their phone to remain connected with family members or friends. Therefore, when developing technology-supported approaches for individuals with AUD not living with partners, app features that allow participants to easily connect with others may be desirable. For example, apps that contain message boards that allow communication between users or being able to use certain <italic>keywords</italic> (eg, “struggling”) to immediately connect with a clinician to receive additional support to address emerging barriers or experiences could be an attractive app feature in this subgroup individuals.</p>
        <p>Moreover, participants with an annual income of ≤US $75,000 also showed higher anxiety without their phone or were more dependent on their device. A Pew Research Center report on mobile phone usage and annual income conducted between 2013 and 2021 showed individuals of this income bracket as being more smartphone-dependent than their higher-income counterparts [<xref ref-type="bibr" rid="ref13">13</xref>]. While it is not clear what contributes to the difference in dependency on smartphones between income groups, this report found individuals of this income level are more likely to be “smartphone only internet users” and less likely to own other devices (eg, a computer or iPad) [<xref ref-type="bibr" rid="ref13">13</xref>]. It is possible that lower financial resources indicate greater increased reliance to on this device to complete many and different tasks. Moreover, AUD is more prevalent among socioeconomically disadvantaged groups than those of a higher income level [<xref ref-type="bibr" rid="ref31">31</xref>,<xref ref-type="bibr" rid="ref32">32</xref>]. This intersection has been associated with a higher prevalence of many chronic conditions, such as liver disease, type 2 diabetes, hypertension, and some cancers, compared to the general population [<xref ref-type="bibr" rid="ref2">2</xref>,<xref ref-type="bibr" rid="ref33">33</xref>,<xref ref-type="bibr" rid="ref34">34</xref>]. The current evidence shows that low-income adults with AUD are significantly dependent on their mobile phone and thus suggests the potential acceptability of mHealth programs among this subgroup. Accordingly, researchers have the opportunity to deliver both clinical and behavioral health intervention approaches that address cognitions and behaviors salient in increasing sobriety and thereby decreasing associated health risks among this group. For example, engagement in physical activity or yoga has shown to be beneficial as an adjunctive tool in treatments for AUD [<xref ref-type="bibr" rid="ref35">35</xref>-<xref ref-type="bibr" rid="ref37">37</xref>]; however, these interventions are small and are typically delivered in person and over many months. Accordingly, mHealth approaches have the potential to reach a large section of this group and promote sobriety on a large scale.</p>
        <p>Lastly, the study findings showed that anxiety and depression symptoms were significant predictors of <italic>Technological Anxiety/Dependence</italic> scores, although they accounted for minimal variance (<italic>R</italic><sup>2</sup>=0.08 and 0.13, respectively). Nevertheless, anxiety and depression symptoms are highly prevalent among individuals with AUD, and mobile phone app programs that would allow participants to track their symptoms may provide insights into trends associated, such as the relationship between anxiety or depression symptoms and alcohol cravings. Additionally, an app feature that could enable participants to share this type of information with their provider could help inform treatment decisions. However, more research is necessary to determine whether media anxiety and phone dependency may, in fact, be contributing toward an increase in anxiety and depression symptoms in this population.</p>

        <title>Limitations and Future Work</title>
        <p>An important limitation of this study is the lack of heterogeneity with respect to participant ethnicity, preventing an assessment of a potential relationship between a particular ethnic group and mobile phone or media constructs. For example, Latinx populations have increased incidence rates of AUD that may be linked to minority stress and socioeconomic status [<xref ref-type="bibr" rid="ref31">31</xref>, <xref ref-type="bibr" rid="ref31">32</xref>]. Assessment of mobile use behaviors among Latinx adults with AUD is an important research area to determine the potential receptiveness of mHealth substance abuse treatment approaches in this group. Accordingly, more research is needed to extend the current understanding of the nature or frequency of mobile phone usage and views of this technology across different demographic subgroups with AUD. In addition, participants enrolled in this study were interested in using a smartphone app to help them increase their physical activity in early recovery. It is possible that the results of this study may not generalize to the broader AUD patient population. Moreover, future studies with a larger sample size with AUD is needed to assess these relationships. Despite these limitations, the findings may help inform future mHealth approaches that can be used to augment addiction treatment in individuals with AUD. Aligned with the goals of precision medicine, mHealth approaches that are tailored to specific individuals needs and characteristics may be more effective in improving overall treatment outcomes.</p>

        <title>Conclusions</title>
        <p>Notwithstanding these limitations, the study findings provide insight into the relationship between age, marital status, income, depression, and anxiety on empirical constructs for mobile phone use behaviors in adults with AUD. Moreover, the study results provide knowledge into mHealth approaches that are likely to appeal to the needs of different demographic adult subgroups with AUD. Our findings accentuate the need to fully understand individuals’ mobile phone use and attitudes toward technology to evaluate their potential influence on the level of engagement with mHealth interventions in different adult groups with AUD.</p>
