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, ...
