ObjectivesThis study pursued three objectives: provide a descriptive behavioral profile of preschool-aged children having disclosed sexual abuse (SA); assess their attachment representations; and explore whether SA characteristics and child attachment security can predict children's symptomatology, while controlling for parental psychological distress. MethodParents consulting a specialized medical clinic in Montreal following the child's disclosure of sexual abuse (n=116) completed measures regarding parental psychological distress (Échelle de Détresse Psychologique de l’Enquête de Santé Québec; Préville, Boyer, Potvin, Perrault, & Légaré, 1992) and behavioral and psychological problems concerning their preschool-aged children (3 to 6 years) (Child Behavior Checklist for Ages 11/2–5 (CBCL) (Achenbach & Rescorla, 2000a). Children responded to a semi-structured interview assessing their attachment representations (Attachment Story Completion Task; Bretherton, Oppenheim, Buchsbaum, & Emde, 1990). Data concerning SA characteristics were provided by medical records (History of Victimization Form; Wolfe, Gentile, & Boudreau, 1987). ResultsSecure attachment was observed in 58.6% of the children evaluated, and 73.3% of the children had experienced a very severe SA. Parental psychological distress, the intra-familial nature of the sexual abuse experienced, and disorganised/disoriented child attachment were found to predict clinical levels of internalizing behavior problems. Clinical levels of externalizing behavior problems were predicted by child age, avoidant attachment and disorganized/disoriented attachment. ConclusionsDisorganised/disoriented attachment brings a unique contribution to the prediction of sexually abused preschoolers’ clinical internalizing and externalizing difficulties, beyond SA characteristics (type and severity) and parental psychological distress. This underscores the importance of attachment representations in the prediction of emotional and behavioural difficulties in sexually abused children. Practice implications: clinical intervention for sexually abused preschoolers should focus on personal and familial variables, namely attachment security and the quality of parent–child relationships.
