The published literature regarding reactions of nonoffending parents to the sexual abuse of their child is reviewed. Research suggests that mothers generally believe their children's allegations, either totally or in part. Although the majority of mothers are supportive/protective, a substantial number are not. Even mothers who are generally supportive and protective often exhibit inconsistent and ambivalent responses. Studies examining factors that predict parental belief support, and protection have failed to yield consistent results. Few studies have examined nonoffending fathers' reactions following disclosure. Both nonoffending mothers and fathers often experience significant distress following their children's allegations. Parental support is consistently associated with the adjustment of sexually abused children. Few studies have examined interventions targeting nonoffending parents, although two series of well-designed studies suggest that cognitive-behavioral treatment that combines parent and child interventions may lead to better adjustment in both the child and the parent. Implications for mental health professionals are provided.
