Introduction Effectiveness of prevention programmes to reduce suicidal-related behaviours among adolescents could improve when systematically involve interventions for parents/caregivers to enhance family functioning and parental skills. We aim to systematically review parental or family-based family prevention interventions and meta-analyse its effectiveness, as evidence on this topic has not been recently and systematically synthesised.
Methods and analysis We will conduct a systematic review and meta-analysis of randomised controlled trials of parent-based prevention interventions to reduce suicidal-related behaviours in adolescents aged 10–19 years. Studies involving a comparison group, postintervention and/or follow-up assessments of suicidal ideation, self-harm, suicidal attempts, psychopathology, emotional regulation and behavioural and functional outcomes will be reviewed.
The CINAHL, CENTRAL, PubMed, Scopus and Web of Science (WOS) databases were searched, without time limits, for eligible studies in English or Spanish, and with results available. Databases were searched from November 2025 to March 2026.
