Methods	Demographic comparison using ethnicity, gender, removal reason, placement history, and length of stay
Participants	Kinship n = 352 Foster n = 638 Drawn from Los Angeles County data that included only adolescents, 16 years of age and older, in relative placements or in non‐relative foster family placements, as well as, only white, African‐American and Hispanic adolescents
Interventions	See Table 2
Outcomes	Behavioural Development ‐ Behavioural Problems Mental Health ‐ Psychiatric Disorders Educational Attainment ‐ Grade Level
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Allocation concealment (selection bias)	High risk	No attempt was made to equate the kinship care and foster care groups through controlling for covariates; Evidence on setting, placement characteristics, and child demographics was reported on the non‐comparability of the groups
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Kinship care and foster care groups did not experience different exposure to the intervention; Uncertain if groups received different services during placement
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Kinship care and foster care groups were defined in same way; There was evidence of biased assessment resulting from the type of placement
Incomplete outcome data (attrition bias) All outcomes	Low risk	All participants were accounted for in the reporting of results; Attrition could not have influenced the results
Selective reporting (reporting bias)	Unclear risk	Instrumentation used to measure the outcomes was specified completely; Reliability and/or validity information was not reported for instrumentation
