Mental disorders and criminal re-referrals in juveniles who sexually offended.

OBJECTIVE: To investigate the prevalence of mental disorders in (subgroups of) juvenile suspects who sexually offended (JSOs), and its relation with criminal re-referrals five to eight years later. METHODS: A sample of 106 JSOs (mean age 15.0 ± 1.5 years) referred to the Dutch Child Protection Board between May 2003 and December 2006 was classified into JSOs with child victims (N = 19), solo JSOs with adolescents and/or adults victims (N = 29), and group JSOs with adolescents and/or adults victims (N = 58). Mental disorders were assessed at baseline by means of a semi-structured interview (K-SADS-PL), the level of functioning by means of the Children's Global Assessment Scale (CGAS) and re-referrals was ascertained from official judicial registration systems. RESULTS: Three quarters of JSOs met criteria for at least one mental disorder. Comorbidity was found in more than half of the subjects and almost two thirds of the JSOs were functionally impaired. As compared to the other subgroups, JSOs with child victims showed higher rates of affective disorders and had a lower overall level of functioning. Furthermore, JSOs re-referred for another sexual offense were more often diagnosed with an affective disorder, were more often sexually abused and had a lower level of global functioning than JSOs who were not re-referred for another sex offense. CONCLUSIONS: JSOs should receive mental assistance, as more than two thirds are functionally impaired due to mental problems. This may not only be important to safeguard the development of the juvenile offender but might also reduce repeated sexual offending.

Offense related characteristics and psychosexual development of juvenile sex offenders.

OBJECTIVE: This article reports on offense related characteristics and the psychosexual development in subgroups of juvenile sex offenders as measured by the Global Assessment Instrument for Juvenile Sex Offenders (GAIJSO). The predictive validity of these characteristics for persistent (sexual) offensive behavior in subgroups of juvenile sex offenders was investigated. METHODS: One hundred seventy four sex offenders (mean age 14.9 SD 1.4) referred by the police to the Dutch Child Protection Board were examined. Offense related characteristics were assessed by means of the GAIJSO and the BARO (a global assessment tool for juvenile delinquents), and criminal careers of the subjects were ascertained from official judicial records. RESULTS: Serious need for comprehensive diagnostics were found on the domains sexual offense and psychosexual development in juvenile sex offenders, especially in the group of child molesters. These youngsters displayed more internalizing and (psychosexual) developmental problems and their sexual offense was more alarming as compared to the other juvenile sex offender subgroups. Although one third of the juveniles had already committed one or more sex offenses prior to the index offense, at follow up (mean follow up period: 36 months SD 18 months) almost no sexual recidivism was found (0.6% of the entire sample). However, a substantial proportion of the entire sample of juvenile sex offenders showed non-sexual (55.6%) and violent recidivism (32.1%). Several predictors for a history of multiple sex offending and non-sexual recidivism were identified. CONCLUSION: This study revealed numerous problems in juvenile sex offenders. Assessment using the GAIJSO is helpful in order to identify indicators for extensive diagnostic assessment. In order to investigate the predictive validity for sexual reoffending a longer follow up period is necessary.

Criminal profiles of violent juvenile sex and violent juvenile non sex offenders: an explorative longitudinal study.

Few studies have longitudinally investigated the criminal profiles of violent juvenile sex and violent juvenile non-sex offenders. To make up for this lack, this study used police records of juveniles to determine the nature of the criminal profiles of violent sex offenders (n = 226) and violent non-sex offenders (n = 4,130). All offenders committed their first offense in 1996 and were followed for 7 years. Results showed that violent sex offenders and violent non-sex offenders cannot be considered a homogeneous group because of different background characteristics and criminal profiles. Sex and violent offenses often constitute a small part of a broader criminal pattern. Further research is necessary to reveal in more detail the developmental and criminological patterns of violent and sexual delinquency. Treatment and intervention programs may benefit from this.

Incarcerated Dutch juvenile sex offenders compared with non-sex offenders.

There is some debate about whether or not sex offenders are similar to non-sex offenders with regard to family background (parental characteristics), personality, and psychopathology. The central aim of this study focused on the comparison of juvenile sex offenders and non-sex offenders. The sample consisted of incarcerated juvenile male sex (n = 30) and non-sex (n = 368) offenders. It appeared that sex offenders resembled non-sex offenders with respect to most of the offender and parental characteristics. Results demonstrated some differences between both groups, while the majority of characteristics were similar. Limitations of the study are discussed, especially the low number of sex offenders, followed by suggestions for further research.

Juvenile sex offenders compared to non-sex offenders: a review of the literature 1995-2005.

An unresolved but clinically important issue in the literature on juvenile delinquency is to what extent juvenile sex offenders resemble non-sex offenders with respect to individual, familial, and environmental characteristics. The current article reviewed published studies (1995-2005) comparing sex offenders with non-sex offenders. The 17 articles meeting the inclusion criteria suggest that differences exist between sex offenders and non-sex offenders on personality characteristics, behavioral problems, history of sexual abuse, nonsexual offending, and peer functioning. Inconsistent results were found for demographic factors, family functioning and background, antisocial attitudes, and intellectual and neurological functioning. Although it is likely that sex offenders can be differentiated from nonsex offenders on a number of characteristics, caution is warranted because of methodological differences between studies and small samples size. Also, studies show that sex offenders are a heterogeneous group. Further research should take into account this heterogeneity by including sex offenders from clearly circumscribed groups and investigating characteristics specifically related to sexual behavior.

Violent juvenile sex offenders compared with violent juvenile nonsex offenders: explorative findings from the Pittsburgh Youth Study.

Only a limited number of studies have compared the psychosocial characteristics of juvenile sex offenders and nonsex offenders. The results of these studies have often been contradictory. Furthermore, studies in normal population groups are rare and most of those studies have been conducted in specific populations. This paper reports on the findings of a prospective, longitudinal study, the Pittsburgh Youth Study, in which violent male sex offenders (n = 39) were compared with violent nonsex offenders (n = 430) based on 66 demographic and psychosocial characteristics. The findings show that the sex offenders resembled the nonsex violent offenders with respect to nearly all child, family, peer and demographic risk factors. Some suggestions are made with regard to future research.

Juvenile sex offenders: a group on its own?

There is some debate about whether sex offenders are similar to non-sex offenders. It is known that sex and non-sex offenders are heterogeneous groups. Comparative studies must take this heterogeneity into account. Based on an aggregated database, a study was conducted among adjudicated juvenile (sex) offenders. The sample consisted of juvenile male sex and non-sex offenders who had been subjected to a psychological assessment at the request of the judge or district attorney. The central question focused on the differences between juvenile sex offenders, in particular rapists and sexual assaulters (n = 57), child molesters (n = 55), and non-sex offenders: violent (n = 85) and nonviolent offenders (n = 80). The results demonstrated that sex offenders differ from non-sex offenders with regard to demographic characteristics, problem behavior, and personality traits. Some reference is made regarding future research.
