Predicting intention to use condoms in homosexual men: An application and extension of the theory of reasoned action

Abstract

A questionnaire based on the Theory of Reasoned Action was developed and tested to identify predictors of intention to use condoms. The questionnaire consisted of three original components: Behavioral Intentions, Attitudes and Subjective Normative Beliefs, and a new component, Behavioral Norms. Age of HIV antibody status were also collected. Internal consistency of the four components of the questionnaire was high: Cronbach's alpha coefficients ranged from 0.76 to 0.87. Logistic modelling identified the significant predictors of intentions to use a condom as Attitudes (Odds Ratio = 2.7, 95% CI 1.80?4.06, P < 0.001) and Behavioral Norms (Odds Ratio = 1.49,95% CI 1.06?2.11, P = 0.03). Contrary to the theory that demographic variables are not important predictive variables of intention, HIV antibody positive status and age were found to directly influence Behavioral Intentions to use a condom. About 50% of men older than 25 years of age intended to use a condom, irrespective of HIV status. Overall, 59% of men 25 years of age and younger intended to use a condom, but the percentage was affected by HIV status; 22% in men who were HIV positive and 63% in men who were HIV negative. These findings indicate that after modification, to include HIV antibody status, Age and Behavioral Norms, the Theory of Reasoned Action can identify significant predictors of intention to use a condom.
