title: Understanding condom use among heroin addicts in methadone maintenance using the information-motivation-behavioral skills model.
abstract: The current study represents the application of a health behavior model to account for unsafe sexual behavior (as opposed to unsafe needle use) among heroin addicts in methadone treatment. The Information-Motivation-Behavioral Skills (IMB) model of HIV preventive behavior asserts that HIV prevention information, motivation, and behavioral skills are fundamental determinants of HIV preventive behavior. Participants (N = 156 heroin-addicted individuals in methadone treatment) completed assessments of their levels of HIV prevention information, motivation, behavioral skills, and safer sexual behavior. Overall measures of fit generated via structural equation modeling indicate that the IMB model adequately fits the data obtained. The constructs of the model accounted for a substantial proportion of the variance in safer sexual behavior, and tests of parameter estimates indicate that while information and motivation had direct and reliable associations with safer sexual behavior in this population, behavioral skills did not. Discussion focuses on the primary roles of HIV prevention information and motivation as determinants of safer sexual behavior in this population, on the lack of a significant contribution of HIV prevention behavioral skills, and on the implications for intervention of this pattern of findings.
