Home Visiting Interventions and Their Impact on Mental Health, Psychosocial, and Parenting Practice Outcomes of Vulnerable Caregivers: A Systematic Review and Meta-Analysis

Past reviews have found home visiting interventions to be successful at improving caregiver outcomes. Though, no review has looked specifically at the effect of home visiting interventions on caregivers with high vulnerability and complex needs. This review aimed to examine and synthesis the literature on the impact of home visiting programs administered to caregivers with young children, high vulnerability and complex needs by professionals/paraprofessionals. Interdisciplinary databases, reference lists, and the Home Visiting Evidence of Effectiveness database were searched for articles that fit the inclusion criteria. Together searches resulted in a total of 623 articles, 34 of these articles were included in the final review, all from high-income countries. Twenty-five interventions were implemented across the 34 studies. Findings showed that these interventions were effective at improving a range of mental health, parenting, and family violence outcomes in caregivers with high vulnerability and complex needs. However, weighted mean standardized effect sizes ranged from 0.01-0.24 (small effect), with only one (i.e., practical parenting skills) of the five significantly different from 0 (standardized mean difference 0.24; 95% CI: 0.10, 0.38; z = 3.39, p = 0.00) and results favoring the control group. Missing information together with considerable variation in interventions, meant that identifying a clear pattern in treatment components that lead to effective verses non-effective interventions was not possible. Further research is therefore needed to assess the effectiveness of these interventions.
