同伴依恋与初中生手机成瘾的关系:有调节的中介效应分析

Peer Attachment and Junior High School Students’ Mobile Phone Addiction: Analysis of a Moderated Mediation Model

为明确同伴依恋与手机成瘾的关系及其机制,本研究构建了一个有调节的中介模型,重点考察了消极情绪的中介作用以及独处能力的调节作用。采用问卷法,对729名初中生的同伴依恋、消极情绪、独处能力及手机成瘾的情况进行调查。结果显示:(1)在控制性别、年龄、年级、是否独生、手机使用年限后,同伴依恋对手机成瘾具有显著的负向预测作用;(2)消极情绪在同伴依恋与手机成瘾的关系中起完全中介作用;(3)同伴依恋对手机成瘾的直接作用及消极情绪的中介作用均会受到独处能力的调节。研究结果不仅有利于从依恋理论及客体关系理论的视角理解同伴依恋与手机成瘾的内在机制,而且对引导初中生形成良好人际关系为其心理社会功能服务具有启示意义。

In order to give an interpretation for the relationship and complex mechanisms between peer attachment and mobile phone addiction, the present study conducted a moderated mediation model to examine the effects of peer attachment, negative affect and the ability to be alone on mobile phone addiction and the underlying mechanism. A total of 729 junior high school students participated in this study. Junior high school students’ peer attachment was measured with Inventory of Peer Attachment. The 21-item version of Depression Anxiety Stress Scale was used to assess negative affect. The ability to be alone was assessed with the Ability to Be Alone Scale. Junior high school students’ mobile phone addiction was measured by the Mobile Phone Addiction Index. All the measures have good reliability and validity. The results showed that:(1) Peer attachment has a negative direct effect on junior high school students’ mobile phone addiction;(2) The negative association between peer attachment and junior high school students’ mobile phone addiction was mediated by negative affect;(3) The mediating effect of negative affect was moderated by the ability to be alone. Specifically, the indirect effect was stronger for junior high school students with the higher ability to be alone than for those with the lower ability to be alone.
