Outcome Measures

Primary Outcomes (3)

  • Depressive Symptoms

    Measured using the Patient Health Questionnaire-9 (PHQ-9)

    At baseline (during about 2 weeks after consent and prior to initiation of study condition procedures), post-intervention (at the conclusion of the 12-week intervention period), and follow-up (approximately 3 months after completion of the intervention)

  • Anxiety Symptoms

    Measured using the Generalized Anxiety Disorder-7 (GAD-7)

    At baseline (during about 2 weeks after consent and prior to initiation of study condition procedures), post-intervention (at the conclusion of the 12-week intervention period), and follow-up (approximately 3 months after completion of the intervention)

  • Perceived Stress

    Measured using the Thai version of the Perceived Stress Scale (T-PSS-10)

    At baseline (during about 2 weeks after consent and prior to initiation of study condition procedures), post-intervention (at the conclusion of the 12-week intervention period), and follow-up (approximately 3 months after completion of the intervention)

Study Arms (2)

Intervention condition

EXPERIMENTAL

Digital CAMMA intervention

Behavioral: Caregiver Mental Health Mobile Application (CAMMA) Intervention

Control condition

ACTIVE COMPARATOR

Enhanced usual care

Behavioral: Usual Care Group

Interventions

12-week system-integrated digital intervention including caregiver-facing mental health self-monitoring tools, self-care and caregiving support modules, facilitated peer interaction, and standardized triage/referral workflows supported by Care Manager / Community Caregiver digital interfaces. Engagement prompts and monitoring dashboards are used to support sustained use.

Intervention condition

12-week enhanced usual care including general health education materials and facilitated group discussions; no access to CAMMA's caregiver mental health monitoring, caregiver-specific self-care module

Control condition

Masking Details
Participants (family caregivers and care recipients), providers (CMs and CCGs), outcome assessors, and data analysts will be blinded to group assignment. Blinding is achieved through cluster randomization by subdistrict, with providers trained and certified to deliver only one protocol based on their assigned cluster. Both arms receive home visits at the same frequency, maintaining participant blinding. Cross-cluster communication is discouraged through training and geographic separation. Only the unblinded study coordinator implementing randomization has access to allocation; this individual has no role in outcome assessment or primary data analysis.
Purpose
HEALTH SERVICES RESEARCH
Intervention Model
PARALLEL
Model Details: The R33 phase of the study will employ a two-arm, parallel-group randomized controlled trial (RCT) to evaluate the effectiveness of the CAMMA intervention in reducing psychological distress among family caregivers of adults with chronic conditions in Thailand. Eligible family caregivers will be randomized in a 1:1 ratio to either the CAMMA intervention arm or an active control condition. The study is designed to assess outcomes longitudinally at baseline, post-intervention, and follow-up, allowing examination of both short-term and sustained intervention effects.
