We examined cultural mistrust of mental health professionals among Black males who are transitioning from the foster care system (N = 74) and its relationship to their level of satisfaction with child welfare services and the frequency of negative social contextual experiences. Results of hierarchical regression analysis showed that the level of satisfaction with child welfare services moderated the relationship between negative social contextual experiences and cultural mistrust of mental health professionals. Specifically, more frequent negative social contextual experiences were related to greater cultural mistrust of mental health professionals for Black males reporting low satisfaction with child welfare services, but not for those reporting high satisfaction with child welfare services. Implications for service delivery are discussed.
