Input: One-hundred-and-two quasi-experimental studies, with 666,615 children are included in this review. The 'Risk of bias' analysis indicates that the evidence base contains studies with unclear risk for selection bias, performance bias, detection bias, reporting bias, and attrition bias, with the highest risk associated with selection bias and the lowest associated with reporting bias. The outcome data suggest that children in kinship foster care experience fewer behavioural problems (standardised mean difference effect size -0.33, 95% confidence interval (CI) -0.49 to -0.17), fewer mental health disorders (odds ratio (OR) 0.51, 95% CI 0.42 to 0.62), better well-being (OR 0.50, 95% CI 0.38 to 0.64), and less placement disruption (OR 0.52, 95% CI 0.40 to 0.69) than do children in non-kinship foster care. For permanency, there was no difference on reunification rates, although children in non-kinship foster care were more likely to be adopted (OR 2.52, 95% CI 1.42 to 4.49), while children in kinship foster care were more likely to be in guardianship (OR 0.26, 95% CI 0.17 to 0.40). Lastly, children in non-kinship foster care were more likely to utilise mental health services (OR 1.79, 95% CI 1.35 to 2.37). This review supports the practice of treating kinship care as a viable out-of-home placement option for children removed from the home for maltreatment. However, this conclusion is tempered by the pronounced methodological and design weaknesses of the included studies.
Output:

This review was designed to help find out if research studies could tell us which kind of placement is best. We found 102 studies with 666,615 children that met the methodological standards we considered acceptable. Wherever possible we combined the data from studies looking at the same outcome for children, in order to be more confident about what the research was telling us. Current best evidence suggests that children in kinship foster care may do better than children in traditional foster care in terms of their behavioural development, mental health functioning, and placement stability. Children in traditional foster care placements may do better with regard to achieving adoption and accessing services they may need. There were no negative effects experienced by children who were placed in kinship care. The major limitation of this systematic review is that the quality of research on kinship care is weakened by the poor methods of the included studies. Implications for practice and future research are discussed.
