AbstractAdult survivors of institutional abuse were interviewed with a comprehensive assessment protocol which included the Childhood Trauma Questionnaire, the Institutional Child Abuse Processes and Coping Inventory, the Structured Clinical Interviews for Disorders of the Diagnostic and Statistical Manual of Mental Disorders IV axis I disorders and personality disorders, the Trauma Symptoms Inventory, a Life Problems Checklist, the Experiences in Close Relationships Inventory and the Kansas Marital Satisfaction Scale. Profiles were identified for subgroups that described severe sexual (N = 60), physical (N = 102), or emotional (N = 85) abuse as their worst forms of maltreatment. Survivors of severe sexual abuse had the most abnormal profile, which was characterised by higher rates of all forms of child maltreatment and higher rates of post‐traumatic stress disorder, alcohol and substance abuse, antisocial personality disorder, trauma symptoms and life problems. Survivors of severe emotional abuse were better adjusted than the other two groups. The profile of survivors of severe physical abuse occupied an intermediate position between the other two groups. A thorough assessment of abuse history and current functioning should be conducted when providing services to adult survivors of institutional abuse, since this may have important implications for the intensity of services required. Survivors of severe sexual abuse may require more intensive services. Copyright © 2009 John Wiley & Sons, Ltd.
