摘　　要：目的:探讨健康行为自我效能和身体活动在数字媒介对健康行为的链式中介作用方法:采用数字媒介量表、健康行为量表、健康行为自我效能量表以及身体活动量表,对江西、安徽、云南各抽取一所本科学校共900名大学生进行调查。结果:①数字媒介对健康行为具有正向预测作用;②健康行为自我效能和身体活动在数字媒介对健康行为的影响中均存在单独中介;③健康行为自我效能和身体活动在数字媒介对大学生健康行为的影响中发挥链式中介作用。结论:数字媒介可以直接影响大学生健康行为,既可以通过健康行为自我效能或身体活动的中介作用,也可以通过两者的链式中介作用正向预测大学生健康行为。Objective:To explore the serial mediating roles of health behavior self efficacy and physical activity in the influence of digital media on health behaviors.Methods:A survey was conducted on a total of 900 college students from three provinces,Jiangxi,Anhui,and Yunnan,each selecting one undergraduate institution.The survey utilized the Digital Media Scale,Health Behavior Scale,Health Behavior Self Efficacy Scale,and Physical Activity Scale.Results:①Digital media has a positive predictive effect on health behaviors.②Both health behavior self efficacy and physical activity serve as individual mediators in the influence of digital media on health behaviors.③Health behavior self efficacy and physical activity exert serial mediating effects in the impact of digital media on college students’health behaviors.Conclusion:Digital media can directly affect the health behavior of college students,which can positively predict the health behavior of college students through the mediation effect of health behavior self efficacy or physical activity,or through the chain mediation effect of both.
