Testing a psychosocial model of sexual communication and sexual risk-taking: A cross-sectional, online survey study of Australian University students.

Objective: Sexually transmitted infection rates are higher among young people relative to other age groups. Despite much investigation, there is not enough research about in-the-moment factors associated with risky sexual behaviour, such as relational and situational variables. The present study sought to test a comprehensive psychosocial model of sexual risk-taking that included a range of factors: individual (emotion dysregulation, impulsivity), relational (attachment, communication), societal (norms, gender), and situational (dating application use, alcohol use).

Methods: 1244 young people aged 18 to 25 years (82.9 % women; 59.2 % single, 36.0 % in a monogamous relationship) participated in an online survey. The cross-sectional model was tested using Structural Equation Modelling.

Results: Sexual communication mediated the relationship between attachment anxiety and sexual risk. However, contrary to predictions, greater sexual communication was related to higher risk. Post-hoc analysis showed that this unexpected relationship may be due to the way sexual risk was measured, as an alternative model specifying casual unprotected sex as the outcome showed no positive relationship between sexual communication and risk.

Conclusion: Findings indicate that young people with anxious attachment are less confident communicating about sexual health. Measures of sexual risk focusing on specific risk activities in context yield different findings to those assessing general sexual behaviours. Findings support interventions focusing on addressing perceived sexual risk norms and the dating application context to reduce risk.
