Background: The Armidilo has two scales--the risk scale and the protective scale. Research has been confined to the risk scale which appears to predict future incidents with medium to large effect sizes. There have been no publications on the use of the protective scale. Methods: The Armidilo was completed on four individuals with IDD who were…

Background: The purpose of the present study was to add to the literature on the predictive accuracy of a dynamic intellectual disability specific risk assessment tool. Method: A dynamic risk assessment for sexual reoffending (ARMIDILO-S), a static risk assessment for sexual offending (STATIC-99), and a static risk assessment for violence…

Background: Several studies have shown the positive effects of sex offender treatment for men with intellectual disabilities who have perpetrated sex offences or inappropriate sexual behaviour. The present study investigates the process of treatment change and compares two groups of offenders against adults and offenders against children. Method:…

Background: There have been several developments in research on emotional disorders in people with intellectual disability (ID). Although a large amount of work has been completed in mainstream clinical fields on the "Beck Anxiety Inventory" (BAI) and the "Beck Depression Inventory"-2nd Edition (BDI-II), to date there has been…

Background: Hayes (1991) and Day (1994) have developed hypotheses about the importance of social and developmental variables in the aetiology of sexual offences in offenders with intellectual disability. The present study is the first of its kind to investigate the perceived quality of life and relationships of sex offenders in comparison to an…

This article reports an evaluation of a community intellectual disability offender service over the period from 1990 to 2001. Men who committed sex offenses or sexually abusive incidents (n = 106) and men who committed other types of offenses and serious incidents (n = 78) are compared on personal characteristics, referral sources, forensic…

Background: This report employs a recently developed assessment on attitudes consistent with sexual offending [Questionnaire on Attitudes Consistent with Sexual Offences (QACSO)] to compare different groups of sex offenders with intellectual disability. Method: Two studies are reported each from a different region and each conducted by different…

This article presents four case studies of male adolescent sex offenders with intellectual disabilities. All were successfully treated in a group program that focused on specific techniques for cognitive change for thinking errors related to sex offending, problem-solving in offending situations, and analysis of behavior and routines consistent…

Although many writers have provided a theoretical framework for treatment of mainstream sex offenders, this research has not been extended to sex offenders with mild intellectual disability. My purpose here is to bring together several research strands to provide a theoretical model for working in this field, including theories of sex offending,…

Background: Research on prediction of violent and sexual offending behaviour has developed considerably in the mainstream criminological literature. Apart from one publication [Quinsey (2004) "Offenders with Developmental Disabilities," pp. 131-142] this has not been extended to the field of intellectual disabilities. Methods: Work on actuarial…

Background: The extensive research on prediction of risk in offenders has developed a number of reliable static risk predictors. There is also a developing body of work on proximal, dynamic risk factors and their importance in predicting violent and sexual offending. Although this work has not been done specifically on offenders with intellectual…

Purpose: Research on dynamic risk assessment has developed over the last 10 years and a number of variables have emerged as being possible predictors of future sexual and violent offences. These variables include hostile attitude/anger and compliance with routine. In 2002, Thornton ("Sexual Abuse: A Journal of Research & Treatment" 14, 139)…
