Protocol: A systematic review and meta‐analysis of randomised controlled trials evaluating the impact of parenting programmes for parents of adolescents (10-18 years) on adolescent mental health outcomes, positive development and the parent-adolescent relationship

The primary objective of this review is to answer the following research question: do parenting programmes for parents of adolescents impact adolescent mental health outcomes, positive development and the parent–adolescent relationship? We will achieve this by systematically searching for and synthesising the extant evaluation evidence that meets the inclusion criteria for this review. The secondary objective of this review is answer the research question: does the impact of parenting programmes for parents of adolescents on adolescent mental health outcomes, positive development, and the parent–adolescent relationship vary by: (a) diagnosis; (b) sociodemographic risk status (e.g., family structure, household income); (c) type of caregiver (e.g., biological parent, foster carer, kinship caregiver); (d) geographical location of the study; (e) intervention setting and modality; (f) type of outcome measurement modality (e.g., observation, self‐report); (g) type of intervention model (prevention, early intervention, treatment, theoretical framework); (h) participant age (parent and/or adolescent); and/or (i) participant gender (parent and/or adolescent)? Data permitting, we will fulfil this objective through subgroup analyses.
