TIVA Mobile Health Intervention for Family Caregivers (TIVA-Pilot)

29 de mayo de 2026 actualizado por: Universidade do Porto

A Mobile Health Intervention for the Promotion of Mental Health in Family Caregivers: Protocol for a Pilot Study

This pilot study aims to evaluate the feasibility, usability, and preliminary effects of the TIVA mobile health intervention in promoting positive mental health among family caregivers of older adults. TIVA is a culturally adapted mobile application based on Lluch's Positive Mental Health model and designed to support caregivers through daily activities, motivational messages, relaxation strategies, and psychoeducational content over a four-week intervention period.

A pilot randomized controlled study with parallel allocation will be conducted involving family caregivers recruited in community and primary healthcare settings in Portugal. Participants will be allocated either to the TIVA intervention group or to a usual care control group. Outcomes will include positive mental health, caregiver burden, usability, satisfaction, adherence, and acceptability. Data will be collected at baseline, post-intervention, and follow-up.

This study intends to contribute to the development of accessible digital mental health strategies to support family caregivers and promote healthy ageing.

Descripción general del estudio

Descripción detallada

This pilot randomized controlled trial aims to evaluate the feasibility, usability, acceptability, and preliminary effects of the TIVA mobile health intervention designed to promote positive mental health among family caregivers of older adults.

The TIVA intervention is a culturally adapted mobile application based on Lluch's Positive 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 in Portugal. Eligible participants will be randomly allocated in a 1:1 ratio to either the intervention group (TIVA app plus usual care) or the control group (usual care only). Due to 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, caregiver burden, usability, satisfaction, adherence, and acceptability. Positive mental health will be assessed using the Positive Mental Health Questionnaire, and caregiver burden will be evaluated using the Zarit Burden Interview.

This study seeks to contribute to the development of accessible digital mental health strategies for family caregivers and to support healthy ageing policies and community-based care.
