Processes of adaptation that foster resilience in response to high stress include affect, cognitive, and behavioral regulation, and social interaction. Digital interventions have application for youth and those who provide them support including social work trainees navigating the stressors of university studies concurrent with practice internships. Research on resilience-enhancing apps is needed to understand the underlying mechanisms by which change occurs and who is most likely to benefit from these interventions. Methods: Social work student participants (N=91) were invited to use the JoyPop app two times daily for 28 days. Baseline ACEs exposure and changes-over-time in affect regulation, stress responsivity, and social support were evaluated after 2 and 4 weeks of app use with t-tests and generalized estimating equation modeling. Results: Participants identified predominantly as cisgender women of European descent, mean age 26 years (SD = 6.78), 70% undergraduates, who reported consistent daily app use (Mean days=26.9, SD=1.90). Self-reported baseline ACEs exposure was high (30% ≥ 5+). We tested change-over-time with generalized estimating equation and saw improvement in affect regulation in the Abbreviated Dysregulation Inventory scale (β=-3.38, p=<.001), the subscales of behavioral (β=-1.63, p=<.001), affect (β=-3.24, p=<.001), and cognitive regulation (β=1.50, p=.009). Perceived stress decreased with app use (β=-2.65, p=<.001) and even more so for participants with reported exposure to more than 5 ACEs (β=-3.786, p=.030). Conclusions: The exploratory findings from our pilot study suggest that consistent use of the app may enhance multidimensional resilience amongst university students who self-report higher than average levels of baseline traumatogenic exposures. Our findings support an approach modeling resilience as a complex, dynamic, multicomponent process supported by resources within and between individuals. Further testing of the mechanisms of adaptation in response to high stress that enhance resilience and identification of the JoyPopTM app features that influence this change is needed to validate that daily app use could help youth with experiences of past and current high stress to better regulate their affect, reduce stress reactivity, and increase resilience.
