短视频使用对女大学生限制性饮食的影响

The Impact of Short-Video Use on Restrained Eating of Female College Students

为了探究短视频使用对女大学生限制性饮食的影响及其中介机制,采用短视频使用强度量表、计划行为理论问卷和荷兰饮食问卷对河南省345名具有短视频使用经验的女大学生进行调查。结果发现:(1)短视频使用、行为态度、主观规范、知觉行为控制与限制性饮食两两显著正相关;(2)短视频使用不能直接影响限制性饮食,但通过行为态度和知觉行为控制的并列中介作用对限制性饮食产生间接影响。研究认为,行为态度和知觉行为控制在短视频和限制性饮食之间起完全中介作用,计划行为理论可以被用来解释短视频使用与女大学生限制性饮食的关系,降低短视频使用强度以改变行为态度和知觉行为控制是干预女大学生限制性饮食的有效策略。

To explore the effects of short-video use on restrained eating and its mediating mechanism in female college students from the perspective of the theory of planned behavior(TPB),a sample of 345 female college students in Henan province who had been use short-videos for more than three months were surveyed with the Short-video Use Intensity Scale,the TPB Questionnaire and the Dutch Eating Behavior Questionnaire.Correlation analysis showed that short-video use,behavioral attitude,subjective norm,perceived behavioral control and restrictive eating were significantly and positively correlated with each another.Multiple mediation modeling indicated that short-video use could not directly affect restrained eating,but could indirectly affect it through the parallel mediating roles of behavioral attitude and perceived behavioral control.It suggests TPB can be used to explain the relationship between short-video use and restrained eating of female college students,and behavioral attitude and perceived behavioral control play as complete mediating roles between them.Therefore,decreasing short-video use intensity to change behavioral attitude and perceived behavioral control is an important strategy to interfere with restrained eating of female college students.
