OBJECTIVES: Mindfulness digital health interventions (DHIs) can support stress management among caregivers of persons living with dementia (PLWD), yet few studies investigate dose-response relationships. METHOD: = 44). Participants were instructed to use HMP-C or WA 10 min per day. This study characterizes the association between app usage and baseline-post-test reductions in perceived stress (PSS-10) using linear regression. RESULTS: ≤ 0.05), but not in HMP-C. CONCLUSION: These findings suggest that HMP-C usage is related to reductions in perceived stress and robust to potential usage barriers. Future research is needed to identify the optimal dose of DHI mindfulness, which balances feasibility and targeted outcomes.
