Mobile CBT for Middle Aged and Older Adults

This study aims to assess a mobile iPhone app called MAYA for use in middle-aged and older adults with anxiety or mood disorders. The MAYA app is designed to teach coping skills for anxiety and depression that are drawn from cognitive behavioral therapy. Participants will be asked to use the app for at least two days a week, 20 minutes on each day, for six weeks. Participants will have weekly check-ins as well as longer assessments at the beginning of the study, week 3, week 6 (end of treatment), and week 12 (follow up). During assessments, participants will answer brief questionnaires designed to assess their symptoms and impressions of the app. The main hypotheses of the study are that participants will complete most of the assigned sessions and that they will rate their impressions of the app highly. The secondary hypotheses are that symptoms of depression and anxiety will decrease with use of the MAYA app.

There is a growing need for accessible, affordable, research-supported treatments designed for older adults. Older adults face challenges that limit their ability to physically access mental health services; thus, mobile app-based interventions may be particularly appealing to individuals in this age range with anxiety or depression who are unable to access more traditional psychotherapy administered in person by a therapist. Mobile technology has been used previously to deliver mental health services for adults with a variety of psychiatric symptoms (Dennis \& O'Toole, 2014). Anxiety frequently co-occurs with depression, with 72% of individuals with anxiety having experienced a history of depression (Moffitt et al., 2007). Current models conceptualize anxiety and depression as a confluence of three broad symptom categories - physiological hyperarousal, low positive affect, and high negative affect (Clark \& Watson, 1991) - that are present to different degrees in different individuals. This study aims to assess the acceptability, feasibility and efficacy of "MAYA", a mobile cognitive behavioral therapy app for anxiety and mood disorders, in middle aged and older adults. This study will collect pilot data over the course of 12 weeks. As this is a pilot study, all participants will use the same version of the app and there will be no control group. Participants will be asked to use the mobile app for at least two days a week, for at least 20 minutes on each day, for 6 weeks. Participants will have weekly check-ins in person or via a HIPAA-compliant virtual meeting platform (e.g., Zoom) to assess intervention adherence and answer brief questionnaires designed to assess feasibility, acceptability, and mood symptoms at baseline, week 3, week 6 (end of treatment), and week 12 (follow up).
