Development of a Mobile App to Support Self-Management of Anxiety and Depression in African American Women: A Usability Study (Preprint)
BACKGROUND Anxiety and depressive disorders are the most common mental health conditions among African American women (AAW). Despite the need for mental health care, AAW significantly underutilize mental health services. Past mHealth studies revealed significant improvement in anxiety or depressive symptoms post-intervention. Use of mobile applications (apps) has the potential to eliminate or mitigate barriers for AAW seeking to access mental health services and resources. OBJECTIVE This study aimed to evaluate the usability of the prototype of an app designed to support self-management of anxiety and depression in AAW. METHODS Individual usability testing sessions were conducted with 15 participants in Chapel Hill, North Carolina. Cognitive walkthrough and a think-aloud protocol were used to evaluate the user interface. Eye tracking glasses were used to record participants’ visual focus and gaze path as they performed tasks. The Questionnaire for User Interface Satisfaction was administered following each session to assess participants’ acceptance of the app. RESULTS Participants positively rated the usability of the prototype and provided recommendations for app improvement. The average of means scores for usability assessment (i.e., overall reactions to the software, screen, terminology and app information, learning, and app capabilities) ranged from 7.2 to 8.8 on a scale from 0 to 9 (low to high rating) for user tasks. Most participants were able to complete each task with limited or no assistance. Design recommendations included improving the user interface by adding graphics and color, adding a tutorial for first-time users, curating a list of Black women therapist within the app, adding details about tracking anxiety and depression in the check-up graphs, informing users that they can use the talk-to-text feature for journal entries to reduce burden, relabeling the mental health information icon, monitoring for crisis support, and improving clickthrough sequencing. CONCLUSIONS This study provided better understanding of user experience with an app tailored to support management of anxiety and depression for AAW, an underserved group. Since AAW have high rates of smartphone ownership, there is a great opportunity to use mobile technology to provide access to needed mental health services and resources. Future work will include incorporating feedback from the usability testing and focus group sessions to refine and further develop the app. The updated app will undergo iterative usability testing prior to launching the pilot study to assess efficacy.
