Risky sexual behaviours: The role of substance use, psychopathic traits, and attachment insecurity among adolescents and young adults in Quebec

The purpose of this study was to examine how substance use, psychopathic traits, and attachment representations explain sexual risk-taking in adolescence. Variables used to define risky sexual behaviours were age at first sexual intercourse and number of lifetime sexual partners. A sample of 1,553 adolescents and young adults completed a battery of questionnaires including measures of substance use, psychopathic traits, attachment representations, and sexual behaviours. Structural equation modelling demonstrated that, in the present sample, risky sexual behaviours were best modelled through both direct effects of avoidant attachment representations and indirect effects of psychopathic traits and abandonment anxiety through increases in substance use. This model was gender-invariant and may represent a contemporary trend toward homogenization of sexual practices among young people in Quebec.
