目的基于知信行理论设计适宜大学新生艾滋病防治的联合干预法,并对干预效果做出评价。方法随机选取大学新生135人,比较干预前后大学新生在艾滋病相关知识、信念、行为方面的变化。结果干预前后大学新生在艾滋病相关知识、信念、行为方面的变化差异有统计学意义(P均<0.05),各维度总分有明显变化,干预前、后知识均分的差值(d=2.59)最大,行为均分的差值(d=0.68)最小。成本效果比为20.27。结论基于知信行模式的联合干预法经济可行,对大学新生艾滋病防治的知识水平提高最快,对态度和行为的转变影响较为缓慢,建议今后分知识、态度、行为阶段进行干预。
Objective To design a joint intervention method suitable for prevention and treatment of AIDS among college freshmen based on the theory of knowledge and belief, and evaluate the effect of intervention. Methods A total of 135 college freshmen were randomly selected to compare the changes of HIV / AIDS related knowledge, beliefs and behaviors among freshmen before and after the intervention. Results There were significant differences in AIDS-related knowledge, beliefs and behaviors among freshmen before and after intervention (all P <0.05). The total score of each dimension changed significantly, and the difference of knowledge sharing before and after intervention (d = 2.59 ) Was the largest, and the difference of behavioral equality (d = 0.68) was the smallest. The cost-effectiveness ratio is 20.27. Conclusion The joint intervention based on the mode of knowledge and belief is feasible and feasible. It has the fastest effect on the AIDS prevention and treatment among freshmen, and has a slow influence on the change of attitude and behavior. It is suggested that intervention should be conducted in the knowledge, attitude and behavior stages in the future.
