Connecting families—randomised controlled trial of poverty screening and financial support navigation for families of young children in primary care: an internal pilot study informed protocol

INTRODUCTION: Poverty can have profound negative impacts on parent, child and family health. Primary care providers are in a unique position to address child poverty. Some team-based models have integrated community support workers (CSWs) for social service system navigation assistance. The overall aim of this study is to rigorously test a poverty reduction intervention (navigation of financial supports) embedded in primary care. The primary objective is to compare parenting stress between CSW-supported, structured review of financial supports and social system navigation (intervention) and receipt of written summary of local resources (usual care). METHODS AND ANALYSIS: ?') will be recruited during a scheduled health supervision visit from primary care practices in Kingston, Ontario. Intervention group participants will have a structured review of financial supports with a trained CSW and will meet up to 6 times over 6 months. Outcomes are measured at baseline, 6 months and 12 months after randomisation. The primary outcome is the Parenting Stress Index Fourth Edition Short Form (PSI-4-SF) total score at 6 months. Secondary outcomes include household income, food insecurity, parent mental health (depression and anxiety) and child health. An internal pilot study was used to obtain more reliable estimates of the SD of PSI-4-SF at 6 months to recalculate the sample size (if needed) and assess randomisation and completion rates. Qualitative interviews conducted 9 months after enrolment explore parent experiences with the CSW intervention. ETHICS AND DISSEMINATION: Research ethics approval by Queen's University Health Sciences REB. Results will be shared with the College of Family Physicians of Canada, the Ontario SPOR SUPPORT Unit and academic forums.
