尽责性对问题性手机使用的影响:时间管理倾向和自我控制的链式中介作用

The Impact of Conscientiousness on Problematic Mobile Phone Use:Time Management and Self-Control as Chain Mediator

采用中国版10项目大五人格量表、问题性手机使用量表、青少年时间管理倾向量表和自我控制量表调查1200名青少年尽责性对问题性手机使用的作用机制。结果表明:尽责性能够直接影响问题性手机使用行为,也能够通过时间管理倾向和自我控制能力的完全中介作用影响问题性手机使用。这说明尽责性可能是作为一种远端的人格变量,通过时间管理倾向和自我控制间接作用于问题性手机使用行为。

Problematic mobile phone use of adolescence has already become an unavoidable social issue on account of the development of communication technology.Since it has a quantity of harmful physical and mental effect,more and more researchers focus on problematic mobile phone use and its influencing factor.According to current studies,personality and self-control has shown to be important predictive variables of problematic mobile phone use.According to the Sociogenomic Model of Personality,personality can not only directly affect specific behaviors,but also explain behaviors through indirect effects of cognitive factors.Specifically,personality may indirectly affect problematic mobile use behaviors by influencing one’s self-control ability.What’s more,time management,which is closely correlated with conscientiousness according to some studies,may influence the ability of self-control as cognitive monitoring.We call this theory the self-control model.Therefore,the major problem we focused on was how and to what extent time management and self-control can influence the process from conscientiousness on problematic mobile phone use.This research collected self-reported data from 1200 teenagers in one high school and one middle school in Beijing,which included the grade of junior one and two together with senior one and two.We measured the level of conscientiousness by the Chinese version of Ten Items Personality Inventory(TIPI-C).The short version of Mobile Phone Problematic Use Scale(MPPUS)was used to gather the current situation about mobile phone use.Time management was assessed by Adolescence Time Management Questionnaire(ATMQ).Adolescence Effortful Control Scale from Early Adolescent Temperament Questionnaire-Revised was used to assess the level of Self-control.The results showed that:(1)Conscientiousness may negatively predict problematic mobile phone use behavior;(2)Conscientiousness influenced problematic mobile phone use behavior through the full mediating effect of self-control ability;(3)Conscientiousness influenced self-control ability through the mediating effect of time management view,thus promoting the change of problematic mobile phone use behavior.That is to say,time management and self-control can fully exert the negative influence of mediating conscientiousness on problematic mobile phone use behavior.These findings make contributions to the mechanism about how conscientiousness can impact the problematic mobile phone use,as well as some ideas about how to deal with problematic mobile phone use through behavior modification.Since conscientiousness is relatively stable and difficult to change,improve the level of time management and self-control in order to decrease the behavior of mobile use seems to be quite feasible.However,extra behavior modification experiments should be done to prove this method.What’s more,this research focused on the overall use of mobile instead of specific use such as entertainment,study,communication or other,further studies can be done based on these.
