Mental Disorder, Predisposition, Prediction, and Ability to Control: Evaluating Sex Offenders for Civil Commitment

Elwood, R. W. — Mon, 09 Nov 2009 13:11:42 PST

Nearly 20 years after the first sexually violent person (SVP) statutes were introduced in the United States, the civil commitment of sex offenders remains controversial. SVP laws require that a sex offender has a mental condition that predisposes them to commit sex offenses and poses a high risk to reoffend because of serious difficulty controlling behavior. The controversy over the commitment of sex offenders is fueled by different interpretations of those key constructs. This article reviews those constructs; evaluates them from clinical, epidemiologic, and legal perspectives; and proposes interpretations that address both the major criticisms of civil commitment and the challenges in SVP assessment.

Circles of Support & Accountability: A Canadian National Replication of Outcome Findings

Wilson, R. J., Cortoni, F., McWhinnie, A. J. — Mon, 09 Nov 2009 13:11:42 PST

Circles of Support & Accountability (COSA) started 15 years ago in Ontario, Canada, as an alternate means of social support to high-risk sexual offenders released at the end of their sentences without any community supervision. The pilot project in South-Central Ontario has since assisted almost 200 offenders. Projects based on this model are now in place in the United Kingdom, several jurisdictions in the United States, and throughout Canada. Initial research into the efficacy of the COSA pilot project showed that participation reduced sexual recidivism by 70% or more in comparison with both matched controls and actuarial norms. The current study sought to replicate these findings using an independent Canadian national sample. A total of 44 high-risk sexual offenders, released at sentence completion and involved in COSA across Canada, were matched to a group of 44 similar offenders not involved in COSA. The average follow-up time was 35 months. Recidivism was defined as having a charge or conviction for a new offense. Results show that offenders in COSA had an 83% reduction in sexual recidivism, a 73% reduction in all types of violent recidivism, and an overall reduction of 71% in all types of recidivism in comparison to the matched offenders. These findings suggest that participation in COSA is not site-specific and provide further evidence for the position that trained and guided community volunteers can and do assist in markedly improving offenders’ chances for successful reintegration.

Absolute Versus Relative Ascertainment of Pedophilia in Men

Blanchard, R., Kuban, M. E., Blak, T., Cantor, J. M., Klassen, P. E., Dickey, R. — Mon, 09 Nov 2009 13:11:42 PST

There are at least two different criteria for assessing pedophilia in men: absolute ascertainment (their sexual interest in children is intense) and relative ascertainment (their sexual interest in children is greater than their interest in adults). The American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, 3rd edition (DSM-III) used relative ascertainment in its diagnostic criteria for pedophilia; this was abandoned and replaced by absolute ascertainment in the DSM-III-R and all subsequent editions. The present study was conducted to demonstrate the continuing need for relative ascertainment, particularly in the laboratory assessment of pedophilia. A total of 402 heterosexual men were selected from a database of patients referred to a specialty clinic. These had undergone phallometric testing, a psychophysiological procedure in which their penile blood volume was monitored while they were presented with a standardized set of laboratory stimuli depicting male and female children, pubescents, and adults.The 130 men selected for the Teleiophilic Profile group responded substantially to prepubescent girls but even more to adult women; the 272 men selected for the Pedophilic Profile group responded weakly to prepubescent girls but even less to adult women. In terms of absolute magnitude, every patient in the Pedophilic Profile group had a lesser penile response to prepubescent girls than every patient in the Teleiophilic Profile group. Nevertheless, the Pedophilic Profile group had a significantly greater number of known sexual offenses against prepubescent girls, indicating that they contained a higher proportion of true pedophiles. These results dramatically demonstrate the utility—or perhaps necessity—of relative ascertainment in the laboratory assessment of erotic age—preference.

Does Victim Age Differentiate Between Perpetrators of Sexual Child Abuse? A Study of Mental Health, Psychosocial Circumstances, and Crimes

Mon, 09 Nov 2009 13:11:42 PST

To test the theory that sexual offenders who abuse very young children (0-5 years) have more severe mental health and psychosocial problems than those who victimize older children, authors compared psychiatric diagnoses, social circumstances, and crime-related data in all sexual offenders against minors referred to forensic psychiatric investigation in Sweden during a 5-year period. Thirty-one men had committed index crimes involving victims between the ages of 0 and 5 years (Group 1), 90 had 6-to 11-year-old victims (Group 2), and 41 had 12- to 15-year-old victims (Group 3). All three offender groups were characterized by severe mental health problems, in many cases fulfilling American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for both Axis I and Axis II diagnoses, but these problems did not differ between groups. Neither did social situation or sexual orientation. Offenders with 0- to 5-year-old victims significantly more often abused both boys and girls. Frequencies of retrospectively diagnosed childhood-onset behavior disorders were high in all three offender groups. The authors’ data did not support previous findings of increasingly severe mental health problems with decreasing victim age.

Female Sex Offender Recidivism: A Large-Scale Empirical Analysis

Sandler, J. C., Freeman, N. J. — Mon, 09 Nov 2009 13:11:42 PST

Using a sample of 1,466 females convicted of a sexual offense in New York State, the current study explored the following: (a) offending prior to the commission of the offenders’ first sexual offense, (b) rates of recidivism following their first sexual offense conviction, and (c) factors associated with the likelihood of sexual recidivism. Results showed the recidivism rates of female sex offenders to be lower than those of male sex offenders for all types of recidivism studied (any rearrest, felony rearrest, violent [including violent sexual] felony rearrest, and sexual rearrest). Several significant differences were found between the group of female sex offenders who sexually recidivated and the group who did not, including crime of first sexual conviction and measures of prior offending.

Construct Validity of the Violence Risk Scale--Sexual Offender Version for Measuring Sexual Deviance

Canales, D. D., Olver, M. E., Wong, S. C. P. — Mon, 09 Nov 2009 13:11:42 PST

Previous studies have identified sexual deviance as a particularly strong predictor of sexual recidivism in sex offenders. The present study examined the construct validity (i.e., convergent and discriminant validity) of the three dynamic factor domains (Sexual Deviance, Criminality, Treatment Responsivity) of the Violence Risk Scale— Sexual Offender version (VRS-SO) as well as the Screening Scale for Pedophilic Interests (SSPI; for comparison purposes) with respect to phallometric measures of sexual deviance. VRS-SO and phallometric data were collected from 124 federally incarcerated sex offenders from a maximum security forensic psychiatric facility. The Sexual Deviance factor and SSPI were positively correlated to varying degrees with computed arousal indexes (Percent Full Erection, difference scores) for child stimuli but were not significantly correlated with nondeviant arousal, supporting the convergent and discriminant validity of these measures, respectively. Convergent validity also appeared stronger for sex offender subtypes with child victims. Criminality and Treatment Responsivity did not correlate with male stimuli, although they were positively correlated with arousal to female profiles. The VRS-SO Sexual Deviance factor and some phallometric indexes of deviant arousal (e.g., female children) were predictive of sexual recidivism whereas the SSPI was not. The pattern of findings across analyses broadly supports the construct validity of the VRS-SO in assessing sexual deviance.
