基于信息-动机-行为技巧模型的女性性工作者艾滋病高危行为研究

A study on AIDS risk behavior based on the information-motivationbehavioral skills model among female sex workers

目的以信息-动机-行为技巧模型为理论基础,分析女性性工作者艾滋病高危行为的影响因素及相互作用机制。方法采用同伴推动法招募328名女性性工作者进行问卷调查,应用结构方程模型建模方法构建该人群的艾滋病高危行为模型。结果建立模型的拟合评价指数均在可接受范围之内,模型中预防信息和动机可通过行为技巧影响预防行为,动机对预防行为直接和间接效应差异均有统计学意义(P<0.05),行为技巧对预防行为的效应大于动机的效应。结论行为技巧对预防行为的效应最大,同时作为中介变量调节着预防信息和动机对预防行为的效应。

Objective To analyze the influncing factors and interaction mechanisms of acquired immune deficiency syn- drome（AIDS） high risk behavior among female sex workers （FSWs） based on the information-motivation-behavioral skills （ IMB ） model. Methods Participants （ n = 328 ） were recruited using respondent-driven sampling method. A self- administered questionnaire was used to collect the data. Structural equation modeling was used to assess the IMB mod- el. Results The fitting evaluation index of the IMB model was accepted. Prevention information and motivation worked through behavioral skills to influence prevention behaviors. Motivation had direct and indirect effects of statisti- cal significance on the prevention behaviors（ P 〈 0.05 ）. Behavioral skills had more effects on prevention behaviors than motivation. Conclusion Behavioral skills had the most effects on prevention behaviors and also acted as a metavariable to regulate the effects of prevention information and motivation on prevention behaviors.
