Abstract:
This study investigated heterosexual HIV risk behaviors, changes in stage of change for safer sex and factors associated with such changes, among a diverse sample of 560 heterosexually active individuals presenting at publicly funded HIV C&T sites. Questionnaires were administrated before HIV C&T, and three months afterwards. Positive serostatus was the most significant predictor of safer behavior after C&T. Many seronegative participants stopped sex with non-main partners. Behaviors with main partners were particularly resistant to change. Predictors of change varied by stage at pre-test. C&T services should tailor approaches and referrals based on stage of change and other client characteristics.
