青年人人格、自我控制双系统与拖延的关系

摘要

Objective:To explore the relationship between personality traits and procrastination in young people and the mediating role of self-control.Methods:A total of 344 college students (191 males and 153 females) were assessed with the Mini-IPIP Scale (Mini-IPIP), Dual-Mode of Self-Control Scale (DMSC-S, including control system and impulse system) and General Procrastination Scale (GPS).Results:The GPS scores were negatively correlated with scores of agreeableness subscale and conscientiousness subscale (r=-0.13, -0.53, Ps＜0.05), and positively correlated with scores of neuroticism subscales (r=0.27, P＜0.01).The structural equation modeling supported the impulse system fully mediated the relationship between neuroticism and procrastination (η2=0.15, 95％CI=0.02-0.25), and those two systems partly mediated the relationship between conscientiousness and procrastination (η2=0.20, 0.20;95％CI=-0.38——0.05, -0.70——0.24).Conclusion:The relationship between youth personality and procrastination may be mediated by a dual system of self-control.Additionally, the degree to how self-control affects the relationship between big five personality trait and procrastination is different under the different types of personality.%目的:探讨青年人人格特质与拖延的关系及自我控制在其中的中介作用.方法:选取某高校一年级研究生344名(男性191人,女性153人),采用简版大五人格量表(Mini-IPIP)、自我控制双系统量表(DMSC-S,包含冲动系统和控制系统两个维度)和一般拖延量表(GPS)进行测量.结果:GPS得分与Mini-IPIP宜人性、尽责性得分呈负相关(r=-0.13、-0.53,P＜0.05和P＜0.01),与神经质得分呈正相关(r=0.27,P＜0.01).以冲动系统和控制系统为中介变量的模型显示冲动系统在宜人性与拖延行为中起完全中介作用(η2=0.65,95％CI=-0.59～-0.15),控制系统在神经质与拖延行为中起完全中介作用(η2=0.15,95％CI=0.02～0.25),冲动系统和控制系统在尽责性对拖延行为中起部分中介作用(η2=0.20、0.20,95％CI=-0.38～-0.05、-0.70～-0.24).结论:青年人人格与拖延行为的关系受自我控制双系统的中介作用,在不同人格维度中自我控制双系统在二者关系中起作用的程度不同.
