College student veterans' experience with a mindfulness- and acceptance-based mobile app intervention for PTSD: A qualitative study.

This study aimed to explore college student military veterans' experience with a mindfulness- and acceptance-based smartphone app intervention. Upon the 4-week participation in the intervention, 23 student veterans took part in semi-structured interviews. In the thematic analysis of the interview transcripts, three main themes emerged: (1) generating momentum of app use; (2) optimizing the functions and benefits of the app; and (3) resolving to deepen the practice of mindfulness and acceptance. Considering the low engagement rates of several previous app-based studies, our results provide a useful framework for incorporating human feedback and support in enhancing users' engagement with the app.
