A Mobile App for Student Veterans With Co-Occurring Academic and Psychiatric Concerns: Pilot Usability and Feasibility Study

BACKGROUND: Over 600,000 student veterans use military benefits to pursue higher education annually, with 75% enrolled as full-time students. Advancing their education is an important step toward improving their employment, financial, and social opportunities. However, student veterans also experience high rates of co-occurring psychiatric concerns like substance use disorder (SUD), posttraumatic stress disorder (PTSD), or depression. For these students, additional psychoeducation, support, and guidance may be required. To support their goals, a mobile app with targeted content for student veterans managing common psychiatric concerns could be particularly helpful. OBJECTIVE: The primary aim of this pilot study was to iteratively revise and assess usability, acceptability, and feasibility of the VetEd mobile app and study procedures. The secondary aim was to explore preliminary changes from preapplication to postapplication use in academic functioning and community reintegration. METHODS: This study used a mixed methods approach; pilot usability testing and iterative revisions were completed across 3 waves of participants (wave 1=4; wave 2=4; wave 3=5; total n=13). Usability was measured using the System Usability Scale (SUS), and acceptability was measured using the Acceptability E-Scale (AES). App use feasibility was collected through app engagement data from the 4 weeks of mobile app use. Study feasibility was assessed by rates of recruitment, retention, and survey completion. Secondary, exploratory measures to assess potential VetEd use outcomes included academic self-efficacy, perceived ability to cope with educational barriers, and community reintegration. Participants were also given the opportunity to complete an exit interview to provide additional feedback. RESULTS: Study feasibility was high, with greater than projected rates of recruitment (4-5 per month), retention (13/13, 100%), and survey completion at all 3 time points (100%, 85%, and 100%, respectively). Overall, 85% (11/13) of both usability and acceptability scores were above the predefined benchmarks. Completion of assigned VetEd activities was high, with participants completing, on average, 90.8% of requested app activities. Secondary exploratory outcomes in academic self-efficacy, coping with educational barriers, and community reintegration were nonsignificant but showed feasibility for use in future fully powered randomized VetEd trials. Exit interviews highlighted that VetEd was easy to use, included pertinent information for both academic and mental health functioning, and had vital information on connecting to additional resources. CONCLUSIONS: Pilot findings suggested that the VetEd mobile app is usable and acceptable as an asynchronous resource for student veterans managing psychiatric concerns. Exit interviews suggested that veterans found app content useful, with relevant information and resources to support their academic functioning. Additional research is needed to assess its effectiveness, implementation, and impact on student veterans nationwide.
