目的：在态度-意向-行为的中介模型的基础上,引入预先应对这一时间知觉特征变量,探索其对健康态度、健康意向和健康行为3个变量的调节作用.方法：选取北京、上海、深圳、西安等地的企业员工220人,分两次进行施测.采用自编健康态度问卷测量健康态度,风险与健康行为量表（RHB）测量健康意向和健康行为,未来取向应对量表（PCI）测量预先应对,用PROCESS程序考察条件化的间接效应,即有中介的调节模型和有调节的中介模型.结果：将健康意向作为因变量,健康态度与预先应对的交互项无统计学意义（P=0.995）,预先应对对健康态度和健康意向的调节作用不成立,因而有中介的调节模型不成立;健康态度到健康意向的回归系数有统计学意义（β=0.93,P＜0.001）,健康态度与预先应对的交互项对健康行为的回归系数有统计学意义（β=0.04,P＜0.01）.事后分析表明,只有在高预先应对（得分高于一个标准差）的情况下健康意向的中介效应才成立,低预先应对（得分低于一个标准差）的情况下中介效应不存在,有调节的中介模型成立.结论：预先应对调节健康意向与健康行为之间的关系,有调节的中介模型成立.而预先应对对健康态度和健康意向之间的关系影响不大,有中介的调节模型不成立.

英文摘要：

Objective： Based on previous finding that intention mediates the relationship between attitude and behavior, this study introduced a temporal perception proactive coping as a moderator, aiming to explore its impact on the relationship among health attitude, health intention and health behavior. Methods： In this longitudinal study, 220 people working in various industrial fields were selected from Beijing, Shanghai, Xi＇an and Shenzhen. Their health attitude, health intention, health behavior and proactive coping were assessed with the Proactive Coping In- ventory, Risk and Health Behaviors and a self-designed questionnaire. The conditional process model was tested by using a versatile computational tool PROCESS. Results： Interaction between health attitude and proactive coping was not significant on health intention （ P = 0. 995）. Therefore, the mediated moderation model was not valid. On the other hand, there was a significant effect of health attitude on health intention （β=0.93, P 〈0. 001）, and a sig- nificant effect of interaction between health attitude and proactive coping on health behavior （β = 0. 04, P 〈 0. 01）. Post-hoc analysis indicated that only when the score of proactive coping was higher （above one standard deviation）, health intention was a mediator between health attitude and health behavior. When the score of proactive coping was lower, the mediate effect was not valid. Therefore, the moderated mediation model wasconfirmed. Conclusion： The moderated mediation model is feasible, that is, proactive coping is a moderator between health intention and health behavior, but has little effect on health attitude-health intention pathway.
