Effectiveness of mHealth-based psychosocial interventions for breast cancer patients and their caregivers: A systematic review and meta-analysis.

Background: Breast cancer causes significant distress in patient-caregiver dyads. While psychosocial and/or mHealth-based interventions have shown efficacy in improving their psychosocial well-being, no reviews have synthesised the effectiveness of such interventions delivered specifically to the breast cancer patient-caregiver dyad.

Objective: To synthesise available evidence examining the effectiveness of mHealth-based psychosocial interventions among breast cancer patient-caregiver dyads in improving their psychosocial well-being (primary outcomes: dyadic adjustment, depression and anxiety; secondary outcomes: stress, symptom distress, social well-being and relationship quality), compared to active or non-active controls.
