Abstract
INTRODUCTION: Substance use disorder (SUD) and problematic substance use are global public health concerns with significant multifaceted implications for physical health and psychosocial well-being. The impact of SUD extends beyond the individual to their family while imposing financial and social burdens on the community. Though family-centred interventions have shown promise in addressing SUD, their implementation and impact in low-income and middle-income countries (LMICs) remain underexplored. METHODS AND ANALYSIS: Per Joanna Briggs Institute's scoping review protocol, a systematic search strategy was employed across OVID Medline, Embase, PsycINFO, Web of Science-Core Collection, Global Health and CINAHL from 22 February 2024 to 26 February 2024, to identify relevant studies focused on family-centred interventions for SUD in LMIC, devoid of publication time and language constraints. Two independent reviewers will screen the titles, abstracts and full texts, with discrepancies resolved through discussion or third-party reviews. The extracted data charted in a structured form will be visualised by diagrams or tables, focusing on the feasibility and impact of family-centred interventions for SUD in LMIC. For qualitative studies, the findings will be synthesised and presented in thematic clusters, and for studies that report quantitative outcomes, specific health, including SUD and psychosocial, outcomes will be synthesised, aligning with the Population, Concept and Context framework. ETHICS AND DISSEMINATION: These data on substance use, psychosocial outcomes and perspectives of individuals with SUD and their families will be presented in narrative format, highlighting patterns and identifying research gaps. This review aims to synthesise the existing evidence on family-centred interventions for improving substance use and/or psychosocial outcomes in individuals with SUD in LMIC and seeks to inform future policy and practice. Ethics approval is not required for this scoping review, and modifications to the review protocol will be disclosed. Findings will be disseminated through conference proceedings and peer-reviewed publication.
