Methods	Demographic comparison using gender, race/ethnicity, age and time in home
Participants	Kinship n = 12 Foster n = 34 Drawn from all kin and unrelated caregivers in the county child welfare database who had infants 10 ‐ 15 months of age, who had been placed with the caregiver within the first 3 months of the child's life and who had been with the identified caregivers continuously for at least 6 months
Interventions	See Table 2
Outcomes	Family Relations ‐ Attachment Placement Stability ‐ Length of Placement
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Allocation concealment (selection bias)	Unclear risk	No attempt was made to equate the kinship care and foster care groups through controlling for covariates; Evidence on placement characteristics and child demographics was reported on the 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	Low risk	Kinship care and foster care groups were defined in same way; There was no evidence of biased assessment resulting from the type of placement
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	All participants were not accounted for in the reporting of results; Uncertain if attrition could 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 some instrumentation
