The relationship between sexual reconviction and the actual level of offence-related sexual behaviour was assessed using a sample of sexual offenders in England and Wales. Official reconviction rates (i.e., Government crime statistics) were calculated using data from the Offenders Index (OI) and the Police National Computer (PNC). These were compared to unofficial rates of offence-related sexua...

We review the human literature examining the effects of neurological insult on human sexual behaviour. We provide a synthesis of the findings to date, and identify key brain regions associated with specific aspects of human sexual behaviour. These include subcortical and cortical regions, with the mesial temporal lobe and the amygdala in particular being a crucial structure in the mediation of ...

In natural populations, genetic variation in seasonal male sexual behaviour could affect behavioural ecology and evolution. In a wild-source population of white-footed mice, Peromyscus leucopus, from Virginia, U.S.A., males experiencing short photoperiod show high levels of genetic variation in reproductive organ mass and neuroendocrine traits related to fertility. We tested whether males from ...

OBJECTIVES To determine the prevalence of STI/HIV risk behaviours in a sample of homosexual men and investigate the psychosocial and cognitive variables associated with these behaviours. METHOD A sample of 123 users of a homosexual men's sexual health clinic completed a questionnaire which included demographic information, psychometric measures, history of sexual risk behaviour, and history o...

OBJECTIVE To determine if risky sexual intercourse, sexually transmitted diseases, and sexual intercourse at an early age are associated with psychiatric disorder. DESIGN Cross sectional study of a birth cohort at age 21 years with assessments presented by computer (for sexual behaviour) and by trained interviewers (for psychiatric disorder). SETTING New Zealand in 1993-4. PARTICIPANTS 99...

OBJECTIVES To identify the changes in sexual behaviour that led to the dramatic reduction in the prevalence of HIV in Uganda in the early 1990s. METHODS Seven different types of evidence were examined: (1) models of HIV prevalence and incidence in Kampala and other sentinel sites in Uganda; (2) reports of behaviour change in the primary newspaper in Uganda; (3) surveys with questions about pe...

Both family structure and processes have been associated with young people's sexual behaviour, but most studies are cross-sectional and focus on only one outcome: age at first intercourse. This paper uses longitudinal data from a survey of Scottish teenagers (N=5041) to show how low parental monitoring predicts early sexual activity for both sexes (with some reverse causation), and for females ...

Sexual selection is a powerful evolutionary mechanism that has shaped the physiology, behaviour and morphology of the sexes to the extent that it can reduce viability while promoting traits that enhance reproductive success. Predation is one of the underlying mechanisms accounting for viability costs of sexual displays. Therefore, we should expect that individuals of the two sexes adjust their ...

Despite the profusion of social cognitive models for the prediction of sexual behaviour, we have only limited knowledge as to the role of individual values in predicting risky sexual activity. This study assessed the relationship between a recently developed value structure and sexual behaviour in the context of rising HIV infection in central and eastern Europe. Five hundred and three responde...

BACKGROUND Adolescents' health is greatly influenced by social determinants, including gender norms. Although research has shown that there is an association between gender attitudes and adolescents' sexual behaviour, few studies have assessed this relationship carefully. The Attitudes toward Women Scale for Adolescents (AWSA) is widely used to assess gender attitudes among adolescents; however...
