特质焦虑对大学生社交媒体依赖的影响：时间管理倾向与压力知觉的链式中介作用

The Effect of Trait Anxiety on Social Media Dependence among College Students: The Chain Mediating Role of Time Management Disposition and Perceived Stress

摘要: 目的：考察大学生特质焦虑对社交媒体依赖的影响，并探讨时间管理倾向和压力知觉在其中的链式中介作用。方法：采用特质焦虑量表、青少年时间管理倾向量表、压力知觉量表和社交媒体成瘾量表，对588名大学生进行调查。结果：① 大学生特质焦虑能显著正向预测社交媒体依赖；② 时间管理倾向和压力知觉在特质焦虑与社交媒体依赖之间分别起中介作用；③ 时间管理倾向和压力知觉在特质焦虑与社交媒体依赖之间起链式中介作用。结论：时间管理倾向和压力知觉在特质焦虑对大学生社交媒体依赖的影响中起到中介作用，二者共同构成“特质焦虑→时间管理倾向→压力知觉→社交媒体依赖”的链式中介路径。

Abstract: Objective: To investigate the effect of trait anxiety on social media dependence among college students and explore the chain mediating role of time management disposition and perceived stress. Methods: A questionnaire survey was conducted among 588 college students using the Trait Anxiety Scale, Adolescent Time Management Disposition Scale, Perceived Stress Scale, and Social Media Dependence Scale. Results: (1) Trait anxiety significantly positively predicted social media dependence among college students; (2) time management disposition and perceived stress separately mediated the relationship between trait anxiety and social media dependence; (3) time management disposition and perceived stress jointly played a chain mediating role in the relationship between trait anxiety and social media dependence. Conclusion: Time management disposition and perceived stress mediated the effect of trait anxiety on social media dependence among college students, and they jointly formed a chain mediation pathway of “trait anxiety → time management disposition → perceived stress → social media dependence”.
