The aim of the present study was to assess the prevalence as well as the possible risk factors of HIV, hepatitis B and hepatitis C, in 194 male prisoners who had been convicted for rape (n=105) or child molestation (n=89). HBsAg, HBeAg, anti-HBc, anti-HBs, anti-HCV and anti-HIV-1/2 were tested for. The participants also completed a standard sociodemographic questionnaire, indicating possible risk factors, the Barratt Impulsiveness Scale, and the life-time history of aggression. Anti-HIV antibodies were not found in any of the prisoners. HBsAg was found in 25 (13%), anti-HBc in 94 (49%), anti-HBs in 40 (21%) and anti-HCV in 13 (6.5%) subjects. Logistic regression analysis showed that anti-HCV positivity was associated with intravenous drug use (OR 20.7, 95% CI 1.1–4.9, P<0.001), while HBsAg positivity was associated separately with being foreign (OR 4.0, 95% CI 0.2–2.5, P<0.01), as well as with impulsiveness score (OR 1.06, 95% CI 0.01–0.11, P<0.02). The prevalence of HBV and HCV infection in this sex offender sample was highly increased in relation to the general population. Since it has been proved that sex offenders are a high-risk group for reoffending, monitoring their health is a necessary step towards prevention of sexually transmitted diseases being spread.
In this chapter, we will discuss sexual offending behavior perpetrated by those individuals who suffer from psychotic mental illness (MI) including schizophrenia, bipolar disorder, delusional disorder,andatypical psychoses.Thediagnosis of MI is often comorbidly associated with other disorders such as personality disorder and intellectually disabilities. Here we intend to concentrate on those with severe and enduring mental health difficulties. While there is relatively good consensusamongresearchers and clinicians about the diagnoses of schizophrenia (Hodgins, 2004), and the assessment and treatment of sexual offenders (Beech, Craig, & Browne, 2009), there is a shortage of research on the assessment and treatment of sexual offenders with psychotic MI (Garrett & Thomas- Peter, 2009). As Hodge and Renwick (2002) argue, “there has been a general lack of consideration given to the factors underpinning mentally disordered offenders . . . and examination of motivational issues in this population is long overdue” (p. 221). This is particularly true for sexual offenders with psychoticMI, and as a result, relatively little attention has been paid to the assessment and treatment of those with psychotic MI who display sexually abusive behaviors.
