TIVA Mobile Health Intervention for Family Caregivers

This pilot randomized controlled trial aims to evaluate the feasibility, usability,acceptability, and preliminary effects of the TIVA mobile health intervention designed topromote positive mental health among family caregivers of older adults.The TIVA intervention is a culturally adapted mobile application based on Lluch'sPositive Mental Health model and derived from the Spanish "Cuidadoras Crónicos" program.The intervention includes daily psychoeducational content, motivational messages,relaxation exercises, and activities focused on emotional well‐being, autonomy,interpersonal relationships, problem‐solving, and self‐care over a four‐week period.Family caregivers will be recruited from community and primary healthcare settings inPortugal. Eligible participants will be randomly allocated in a 1:1 ratio to either theintervention group (TIVA app plus usual care) or the control group (usual care only). Dueto the nature of the intervention, participant blinding will not be feasible.Data collection will occur at baseline (T0), immediately after the intervention period(T1), and at follow‐up (T2). Outcomes will include positive mental health, caregiverburden, usability, satisfaction, adherence, and acceptability. Positive mental healthwill be assessed using the Positive Mental Health Questionnaire, and caregiver burdenwill be evaluated using the Zarit Burden Interview.This study seeks to contribute to the development of accessible digital mental healthstrategies for family caregivers and to support healthy ageing policies andcommunity‐based care.
