Substance misuse is a major problem among individuals involved in forensic-correctional mental health services. Urine drug screening detects substance use and deters the entry of contraband into forensic-correctional units, albeit with limitations. For example, a point-of-care urine sample may not be possible and patients can alter or substitute samples to avoid detection, highlighting the role of ancillary tools to detect contraband substances.

Purpose Of Review: Sexual offending perpetrated by women has historically been overlooked and understudied, and the potentially unique impact of that abuse is even more so.

Recent Findings: Women who have sexually offended against children typically do so against older boys, use little or no forms of force or coercion during the abuse, and are unlikely to be prosecuted or sentenced following the abuse. Boys whom women have sexually abused are unlikely to report or disclose the abuse that they have experienced, perhaps because social structures surrounding sexual abuse of boys by women are designed to minimize, excuse, or even encourage such sexual contact.

Despite a multitude of theoretical views, it is still unclear how individuals develop and sustain paraphilic interests (e.g., sexual attraction to children, interest in non-consensual violence).

While epidemiological description of psychiatric morbidity can promote evidenceinformed mental health services, there is a paucity of such evidence among incarcerated individuals in prisons with underserved healthcare. We evaluated 250 incarcerated individuals detained in an underserved prison in north-western Nigeria with the Mini International Neuropsychiatric Inventory (MINI). Predominantly, study participants were men (97.

The primary aim of these guidelines was to evaluate the role of pharmacological agents in the treatment of adolescents with paraphilic disorders who are also sexual offenders or at-risk of sexual offending. Psychotherapeutic and psychosocial treatments were also reviewed. Adolescents with paraphilic disorders specifically present a different therapeutic challenge as compared to adults.

The treatment of paraphilias remains a challenge in the mental health field. Combined pharmacologic and psychotherapeutic treatment is associated with better efficacy. The gold standard treatment of severe paraphilias in adult males is antiandrogen treatment with cognitive behavioral therapy.

There are many misconceptions about sexual offender treatment. This is not only a problem in the lay press and media but is also a problem amongst mental health professionals. In part, this relates to the inadequate teaching about sexual deviation in medical schools and psychiatric residency programs and even in forensic psychiatric fellowships.

Hormonal factors are important in multifactorial theories of sexual offending. The relationship between hormones and aggression in nonhumans is well established, but the putative effect in humans is more complex, and the direction of the effect is usually unclear. In this study, a large sample (N = 771) of adult male sex offenders was assessed between 1982 and 1996.

Biological factors are likely predisposing and modulating elements in sexually deviant behavior. The observation that paraphilic behavior tends to cluster in some families is intriguing and potentially raises questions as to whether shared genetic factors may play a role in the transmission of paraphilia. This pilot study introduces five families in which we found presence of paraphilia over generations.

Background: This study attempted to validate a clinical typology of dysfunctional anger proposed by DiGiuseppe and Tafrate (2007) using assessment data obtained from 197 participants assessed at an outpatient clinic for anger problems.

Methods: Several self-report scales assessing anger, hostility, impulsivity and aggression, as well as a structured interview regarding anger experience and expression, were administered; Axis I and II comorbidity were assessed using clinical assessment and the SCID-II PQ.

Results: We found support for four of the proposed eight types described by DiGiuseppe and Tafrate - Pervasive Dysfunctional Anger, Impulsive Type; Pervasive Dysfunctional Anger, Mixed Type; Impulsive Aggressive Dysfunctional Anger; and Suppressed Dysfunctional Anger - with significant, predicted group differences on self-report measures of anger, aggression, and impulsivity, as well as differences in Axis I and II diagnoses.

The field of medicine has moved toward best practices based on evidence. There is pressure on all medical disciplines, including forensic psychiatry, to adopt this approach. Some areas of forensic psychiatry have a stronger scientific basis that clearly fits the definition of evidence-based medicine than do other areas.

Objective: In this longitudinal study, the predictive validity of a psychiatric diagnosis of sexual sadism was compared with three behavioral indicators of sadism: index sexual offense violence, sexual intrusiveness, and phallometrically assessed sexual arousal to depictions of sexual or nonsexual violence.

Method: Five hundred and eighty six adult male sexual offenders were assessed between 1982 and 1992, and these offenders were followed for up to 20-years postrelease via official criminal records. Assessment information included the Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnosis, offense characteristics, phallometric assessment results, and an actuarial risk measure (the Sex Offender Risk Appraisal Guide).

Objectives: The primary aim of these guidelines was to evaluate the role of pharmacological agents in the treatment and management of paraphilia, with a focus on the treatment of adults males. Because such treatments are not delivered in isolation, the role of specific psychosocial and psychotherapeutic interventions was also briefly covered. These guidelines are intended for use in clinical practice by clinicians who diagnose and treat patients with paraphilia.

The purpose of this study is to examine the predictive accuracy of the Risk Matrix 2000 on an independent sample of 351 sexual offenders, followed in the community for an average duration of 11.4 years (range 0-20 years, SD = 4.4 years).

This study examined whether there were variables that moderated the relationship between denial and recidivism among adult male sexual offenders. The first study (N = 489) found that the relationship with sexual recidivism was moderated by risk (as measured by the Rapid Risk Assessment for Sexual Offense Recidivism) but not by psychopathy (as measured by the Psychopathy Checklist-Revised). Contrary to expectations, denial was associated with increased sexual recidivism among the low-risk offenders and with decreased recidivism among the high-risk offenders.

The relationship between incarceration and recidivism was investigated in a sample of 627 adult male sexual offenders. Incarceration for the index offense was unrelated to sexual or violent recidivism. This was the case whether incarceration was examined as a dichotomous variable (incarceration vs.

This study examined the utility of the diagnosis of pedophilia in a sample of extra-familial child molesters assessed at a university teaching hospital between 1982 and 1992. Pedophilia was defined in one of four ways: (1) DSM diagnosis made by a psychiatrist; (2) deviant phallometric profile; (3) DSM diagnosis and a deviant phallometric profile; and, (4) high scores based on the Screening Scale for Pedophilic Interest (Seto & Lalumière, 2001). Demographic data, psychological tests, and offence history were obtained and group differences were analyzed along with the ability of certain variables to contribute uniquely to the classification of pedophilia.

Exhibitionism has historically been viewed as more of a nuisance than a serious criminal justice matter. Research has demonstrated that the number of exhibitionists who are detected re-offending is a significant under-representation of the number who actually re-offend. The objective of this study was to extend a previous study conducted on exhibitionists, while attempting to solve the limitations described in that study.

On sexual violence.

Curr Opin Psychiatry

September 2006

Purpose Of Review: Sexual violence is a multidimensional concept that is not completely understood even within forensic psychiatry. Violent sexual behaviour such as sexually sadistic homicides would be included within the definition, but it is commonly defined more broadly as any deviant sexual behaviour. In this review, the broadest definition of sexual violence is used in order to facilitate the most comprehensive review of scientific articles in the field.
