Mobile Intervention for Mental Health of Family Caregivers in Thailand

The R33 randomized controlled trial will test whether CAMMA leads to meaningful reductions in depressive symptoms, anxiety, and perceived stress among family caregivers, compared with an active control condition. Consistent with the underlying caregiving risk framework, the trial will also examine hypothesized mediators-including self-care skills, caregiving self-efficacy, caregiver burden, and engagement with intervention components-to clarify mechanisms of action.

By embedding the intervention within existing service delivery structures and engaging frontline care managers and community care givers as active participants, the R33 trial is designed to generate evidence that is both clinically meaningful and implementation-relevant. This approach responds directly to the need for scalable, sustainable strategies to support caregiver mental health in low- and middle-income country settings and provides a strong empirical foundation for future dissemination and scale-up.
