We examined child, family and system-related factors associated with reunification across African American, Latino, Asian and White families involved in the child welfare system in one large and ethnically diverse California County. Data were obtained from extensive reviews of child welfare case records and multivariate analysis was performed on a wide array of variables not found in previous research. Results indicated that when taking other factors into account, ethnicity was not a strong predictor of reunification. Factors that predicted reunification varied across ethnic groups, with none of the predictors being significant for the Asian group. Implications and suggestions for further research are discussed.
