情绪表达抑制在成人依恋与大学生手机成瘾间的中介作用

Adult attachment and emotion expressive suppression as predictors of cell phone addiction

目的:探讨成人依恋对大学生手机成瘾的影响及其作用机制,为大学生手机成瘾的预防与干预提供实证依据。方法:整群随机抽取江苏省755名在校大学生为研究对象,采用亲密关系经历量表(Experience in Close Relationship Inventory,ECR)、手机成瘾指数量表(Mobile Phone Addiction Index,MPAI)、情绪调节问卷(Emotion Regulation Questionnaire,ERQ)进行调查。结果:大学生手机成瘾检出率为5.12%,不同年级、不同专业大学生的手机成瘾得分有显著差异性(F=5.13,16.47;P<0.01),其中,大一学生手机成瘾得分最高,医学专业学生手机成瘾得分最低。相关分析显示,手机成瘾与依恋焦虑、依恋回避和情绪表达抑制均呈显著正相关关系(r=0.37,0.18,0.18;P<0.01)。中介效应分析发现,依恋焦虑显著正向预测手机成瘾(β=0.35,P<0.001),情绪表达抑制在依恋焦虑对手机成瘾的影响中起部分中介作用(中介效应值=0.014,Bootstrap 95%CI=0.004~0.030);依恋回避对手机成瘾的直接效应无统计学意义,完全通过情绪表达抑制影响手机成瘾(中介效应值=0.017,Bootstrap 95%CI=0.005~0.035)。结论:成人依恋和情绪表达抑制是大学生手机成瘾的重要影响因素,成人依恋可通过情绪表达抑制间接影响手机成瘾。

Objective:To explore the relationship among adult attachment,emotion expressive suppression and mobile phone addiction in college students,and provide the reference for reducing their mobile phone addiction.Methods:Experience in Close Relationship Inventory,Mobile Phone Addiction Index,and Emotion Regulation Questionnaire were administrated to a total of 755 college students in Jiangsu province.Results:There were significant differences of mobile phone addiction in grades and majors(F=5.13,16.47;P<0.01).The scores of mobile phone addiction of freshmen were higher than those of sophomores,juniors and above,and the scores of medical students were lower than those of social science and arts.Cell phone addiction was positively correlated to attachment anxiety,attachment avoidance and emotion expressive suppression(r=0.37,0.18,0.18;P<0.01).Attachment anxiety can positively predict cell phone addiction(β=0.35,P<0.001),and emotion expressive suppression worked as a partial mediating role in the relationship between attachment anxiety and cell phone addiction(indirect effect=0.014,Bootstrap 95%CI=0.004~0.030);emotion expressive suppression served as a full mediating role in the relationship between attachment avoidance and cell phone addiction(indirect effect=0.017,Bootstrap 95%CI=0.005~0.035).Conclusion:Adult attachment and emotion expressive suppression are two important predictors of cell phone addiction in college students,and emotion expressive suppression serves as a mediating role on the relationship between adult attachment and cell phone addiction.
