Testa 2001.

Methods	Multivariate effect sizes adjusted using covariates for age, duration of placement, kinship status, gender, placement variables, and degree of relatedness
Participants	Kinship n = 955 Foster n = 955 Data drawn from 2 sources: (1) the IDCFS Integrated Database designed for the Department of the Chapin Hall Center for Children, and (2) the 1994 RCSA survey Administrative case records extracted from the Integrated Database of kinship and non‐related foster placements that began in Cook County, Illinois between July 1 1991 and June 30 1995 ‐ placements tracked longitudinally with administrative data until case resolution, placement disruption or June 30 1999 Dataset created by linking records from the Integrated Database to RCSA respondents ‐ a comparable sample of children in non‐related foster care was matched by the child's age and duration of placement
Interventions	See Table 2
Outcomes	Placement Stability ‐ Placement Disruption Permanency ‐ Adoption; Guardianship
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Allocation concealment (selection bias)	Low risk	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 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	Uncertain if 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	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 some instrumentation
