The non-victimized siblings in incestuous families have often been ignored in research, literature, and treatment. This study explored these siblings' 1) relationship to the victim, 2) attribution of blame, and 3) adjustment. Participants were 30 non-victimized siblings of incest victims, between the ages of 8 and 14. They completed the Sibling Relationship Questionnaire, the Revised Children's Manifest Anxiety Scale, the Self-perception Profile for Children, the Children's Depression Inventory, and a questionnaire developed for this research. Participants' scores were compared with the normative sample scores on several measures. Siblings perceived little warmth and closeness in their relationships to their victimized sisters. Rivalry and conflict were within normal limits. Siblings blamed victims and other family members less than expected, with the greatest amount of blame attributed to perpetrators. Adjustment was impaired. Males demonstrated less athletic competence, less global self-worth, more worry and oversensitivity than normative samples. Females showed a tendency toward less global self-worth and heightened general anxiety. Siblings' overall level of emotional distress was higher than most of the normative samples.
