信息-动机-行为技能(IMB)模型(Fisher&Fisher，1992)被用作预测被诊断患有严重精神疾病的滥用药物的男性和女性(n=320；150名男性和170名女性，主要是少数族裔)无保护性行为的理论框架。在结构方程模型中，性别、HIV传播知识、支持避孕套的规范和态度的动机变量以及感知的敏感度预测了行为技能标记物：避孕套使用技能和避孕套使用自我效能。与模型中的其他变量一起，避孕套技巧和避孕套自我效能被假设为预测六个月内避孕套的使用情况。结果表明，女性性别、积极的避孕套态度和传播知识可以预测更多的避孕套技能。支持避孕套的标准、较低的感知敏感度和较高的避孕套自我效能预测了较低的无保护性行为比率。对避孕套的积极态度对无保护性行为的发生率有显著的间接影响，这种影响是通过避孕套使用自我效能感来实现的。结果表明，改变个人对避孕套的态度，并在重要的其他人中加强支持避孕套的态度，将鼓励严重精神病(SMI)成年人使用避孕套，这些成年人是艾滋病毒和其他性传播疾病(STDS)的高危人群。
The information-motivation-behavioral skills (IMB) model (Fisher & Fisher, 1992) was used as the theoretical framework for predicting unprotected sexual behavior among substance abusing men and women diagnosed with serious mental illnesses (n = 320; 150 men and 170 women, primarily of minority ethnicity). In a structural equation model, gender, HIV transmission knowledge, and motivational variables of pro-condom norms and attitudes, and perceived susceptibility predicted behavioral skills markers: condom use skills and condom use self-efficacy. Along with the other variables in the model, condom skills and condom self-efficacy were hypothesized to predict condom use over a six-month period. Results showed that greater condom skills were predicted by female gender, positive condom attitudes, and transmission knowledge. Engaging in lower rates of unprotected sex was predicted by pro-condom norms, less perceived susceptibility, and greater condom self-efficacy. Positive attitudes toward condoms had a significant indirect effect on rates of unprotected sex, exerting its influence through condom use self-efficacy. Results suggest that changing personal attitudes about condoms and reinforcing pro-condom attitudes among significant others will encourage condom use among seriously mentally ill (SMI) adults who are at high risk for HIV and other sexually transmitted diseases (STDs).
