| 中文摘要: |
| 目的 拟建立预防艾滋病知识-动机-心理模型并通过结构方程模型验证,为制定MSM人群的艾滋病综合防治规划提供科学依据。方法 在新疆乌鲁木齐市两个MSM非政府组织,通过滚雪球法招募MSM 550人,采用问卷调查获取其艾滋病防治相关信息,信息完整者477人。由文献及课题组前期研究确定影响艾滋病预防行为的相关因素,建立MSM预防艾滋病知识-动机-心理模型。利用结构方程模型拟合问卷数据并对模型进行修正,验证艾滋病相关知识、动机、心理与预防行为的关系及影响程度。结果 结构方程模型拟合良好,修正后拟合指数:RMSEA=0.035、NFI=0.965、RFI=0.920。修正后外生潜变量包含动机、知识、心理;内生潜变量为预防行为。动机、知识、心理对预防行为的标准化总效应分别为0.44、0.41、0.17,动机、知识与心理间相关系数分别为0.16、-0.17(P<0.05),动机与知识相关系数无统计学意义。结论 MSM人群中存在知识动机分离情况。在进行艾滋病相关知识宣传教育的同时,应把动机提升作为预防艾滋病的新突破点,并通过正面引导减轻、消除MSM人群的消极心理。 |

| Objective Knowledge-motivation-psychological model was set up and tested through structural equation model to provide evidence on HIV prevention related strategy in Men who have Sex with Men(MSM).Methods Snowball sampling method was used to recruit a total of 550 MSM volunteers from two MSM Non-Governmental Organizations in Urumqi, Xinjiang province.HIV prevention related information on MSM was collected through a questionnaire survey.A total of 477 volunteers showed with complete information.HIV prevention related Knowledge-motivation-psychological model was built under related experience and literature.Relations between knowledge, motivation and psychological was studied, using a‘structural equation model’with data from the fitting questionnaires and modification of the model.Results Structural equation model presented good fitting Results.After revising the fitting index:RMSEA was 0.035, NFI was 0.965 and RFI was 0.920.Thereafter the exogenous latent variables would include knowledge, motivation and psychological effects.The endogenous latent variable appeared as prevention related behaviors.The standardized total effects of motivation, knowledge, psychological on prevention behavior were 0.44, 0.41 and 0.17 respectively.Correlation coefficient of motivation and psychological effects was 0.16.Correlation coefficient on knowledge and psychological effects was-0.17(P<0.05).Correlation coefficient of knowledge and motivation did not show statistical significance.Conclusion Knowledge of HIV and motivation of HIV prevention did not show any accordance in MSM population.It was necessary to increase the awareness and to improve the motivation of HIV prevention in MSM population. |
