Research is attempting to examine the causes and effects of incestual child abuse and has discovered more complicated temporary and long-term repercussions than previously suspected. Fifteen subjects in a residential facility participated in a study to examine the self-concept and intellect of girls who had been victims of incest. Their scores on the Tennessee Self Concept Scale and the Wechsler Intelligence Scale for Children (WISC) were compared to the normative sample for the two instruments. Statistically significant differences were found between the incest group and the normative group on the Tennessee Self Concept subscores for general maladjustment, the Psychosis Scale and the Neurosis Scale. The incest group scored significantly lower on the Full Score and Verbal Scores on the WISC. The findings suggest that treatment of children who have been incest victims should include activities to improve their self-concepts. (Author/JAC)
