Effectively engaging parents has been a continuing challenge for child protection workers. A lack of engagement can lead to significant negative consequences for families. This preliminary study explored the ability of family factors (e.g.; legal involvement, history with child protective services, substance abuse, child placement, intimate partner violence, identifying as Black, Latino or biracial) to predict parent engagement with child welfare services. A four dimensional measure of engagement with child protective services (Yatchmenoff, Res Soc Work Pract 15(2):84–96, 2005) was used which included receptivity, buy-in, working relationship and mistrust. The variables of parental substance abuse, intimate partner violence and identifying as Black, Latino or biracial were significant predictors of all four dimensions of engagement although each dimension was predicted by a unique combination of these factors. Substance abuse positively predicted engagement while intimate partner violence and identifying as Black, Latino or biracial negatively predicted engagement. The implications of these findings for child protection practice are described. Recommendations are made for future research.
