PROTOCOL: Psychosocial, pharmacological and legal interventions for improving the psychosocial outcomes of children with substance misusing parents

Abstract This review aims to first enhance and update existing reviews by comprehensively synthesising the full array of psychosocial, pharmacological and legal interventions that aim to improve the psychosocial outcomes of children with substance misusing parents. Second, the review aims to use network meta‐analysis to integrate and examine the comparative impact of these interventions. Specifically, the review will address the following research questions: (1) What is the comparative impact of psychosocial, pharmacological, and legal interventions for improving the psychosocial outcomes of children with substance misusing parents? (2) Does the impact of interventions vary according to the child developmental period (e.g., infancy, early childhood, adolescence) or the type of (a) outcome measure; (b) substance misuse; (c) practitioner implementing the intervention; or (d) intervention setting? (3) Does the impact of interventions vary by the country of implementation?
