APPLICATION OF AN INTEGRATED BEHAVIORAL-MODEL TO PREDICT CONDOM USE -A PROSPECTIVE-STUDY AMONG HIGH HIV RISK GROUPS

An integrated theoretical model using constructs from multiple behavio ral models was applied to understand and predict condom use among a sa mple of injecting drug users, commercial sex workers, men who have sex with men, and multipartnered heterosexuals. Elicitation interviews we re conducted to develop a questionnaire to measure model constructs th at may be predictive of condom use for sex with vaginal, anal, and ora l regular and casual partners. A prospective survey design was used, w ith 993 participants interviewed at Time 1, and 686 returning for Time 2 interviews 3 months later. Regression analyses were conducted using Time 1 measures to predict intention and Time 2 behavior. Strong supp ort was found for a model that includes attitude, social norm, and fac ilitators/constraints as predictors of behavior, with multiple correla tions in the .20 to .40 range. Findings also indicate perceived contro l and facilitators/constraints are distinct constructs and both, along with attitude and social norm, contribute to explaining behavioral in tention. Implications for intervention development are discussed.
