PURPOSE This study used a mindfulness- and acceptance-based mobile app to examine the relationships between resilience, mindfulness, experiential avoidance, and posttraumatic stress disorder (PTSD) symptoms. DESIGN AND METHODS A quasi-experimental pre-posttest, single-group study design was used. A total of 23 college student veterans used the app for 4 weeks. Outcomes of resilience, mindfulness, experiential avoidance, and PTSD were measured at three time-points (baseline, end of Week 2, and end of Week 4). FINDINGS All outcomes significantly improved at postintervention. Improvements in resilience and PTSD significantly correlated with improvement in mindfulness. PRACTICE IMPLICATIONS Mindfulness- and acceptance-based mobile apps can be safely used by individuals with PTSD as a complementary approach to enhance resilient coping with PTSD.
