时间洞察力特质对大学生饮食失调的影响:自我控制的中介作用

Impact of time perspective on eating disorders in college students:the mediating role of self-control

目的考察大学生的时间洞察力特质类型对其饮食失调行为的影响以及自我控制在其中的中介作用。方法采用时间洞察力问卷、自我控制问卷和进食态度问卷中文版对367名大学生进行调查。结果①现在时间定向特质与自我控制呈负相关(r=-0.162,P<0.01),与饮食失调呈正相关(r=0.384,P<0.01);未来时间定向特质与自我控制呈正相关(r=0.323,P<0.01),与饮食失调行为呈负相关(r=-0.363,P<0.01);②现在时间定向特质能正向预测饮食失调行为(β=0.24,t=7.95,P<0.01),而未来时间定向特质能负向预测饮食失调行为(β=-0.29,t=-7.43,P<0.01)结论大学生的时间洞察力类型可以通过自我控制的中介作用影响其饮食失调行为的发生。

Objective To investigate the impact of time perspectives on disordered eating behaviors and the mediating role of self-control in college students.Methods A questionnaire survey was conducted among 367 college students using the Chinese versions of the Zimbardo Time Perspective Inventory,Self-Control Scale,and Eating Attitudes Test.Results①The present-oriented time perspective was negatively correlated with selfcontrol(r=-0.162,P<0.01)and positively correlated with eating disorders(r=0.384,P<0.01);the the future-oriented time perspective was positively correlated with self-control(r=0.323,P<0.01)and negatively correlated with eating disorders(r=-0.363,P<0.01).②Significantly,the present-oriented time perspective positively predicted the eating disorders(β=0.24,t=7.95,P<0.01),whereas the future-oriented time perspective negatively predicted the disordered eating behaviors(β=-0.29,t=-7.43,P<0.01).Conclusion Among the college students,the type of time perspective had an impact on their disordered eating behaviors via the mediating role of self-control.
