目前的研究代表了一个健康行为模式的应用，以说明不安全的性行为（反对不安全的针头使用）在海洛因成瘾者在美沙酮治疗。信息-动机-行为技能（IMB）模型认为，艾滋病预防信息、动机和行为技能是艾滋病预防行为的基本决定因素。参与者（N = 156海洛因成瘾者在美沙酮治疗）完成了他们的艾滋病毒预防信息，动机，行为技能和安全性行为水平的评估。通过结构方程模型生成的拟合的总体措施表明，IMB模型充分拟合所获得的数据。该模型的结构在安全性行为的方差中占很大比例，参数估计的检验表明，虽然信息和动机与该人群中的安全性行为有直接和可靠的关联，但行为技能没有。讨论的重点是艾滋病毒预防信息和动机的主要作用，在这一人群中的安全性行为的决定因素，缺乏一个显着的贡献，艾滋病毒预防行为技能，并对干预的影响，这种模式的调查结果。
The current study represents the application of a health behavior model to account for unsafe sexual behavior las 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.
