愉悦追求在自我调节疲劳与大学生智能手机成瘾之间的中介作用:自然联结的调节作用

采用问卷法对564名大学生进行调查，考察愉悦追求在自我调节疲劳和智能手机成瘾之间的中介作用，以及该中介作用是否会受到自然联结的调节。结果表明：（1）自我调节疲劳对大学生智能手机成瘾具有显著的正向预测作用；（2）愉悦追求在自我调节疲劳与大学生智能手机成瘾之间起着部分中介作用；（3）自我调节疲劳和愉悦追求的关系（中介效应的前半段路径）受到自然联结的调节，即自我调节疲劳对愉悦追求的正向影响随着自然联结的增强而减弱。因此，自我调节疲劳和大学生智能手机成瘾之间存在有调节的中介效应。

The Mediating Effects of Pursuing Pleasure between Self-regulatory Fatigue and Smartphone Addiction among Undergraduate Students: The Moderating Effects of Connectedness to Nature

To investigate the impact of self-regulatory fatigue on the smartphone addiction, 564 undergraduate students were recruited to participate in this study, and they anonymously filled out questionnaires regarding self-regulatory fatigue, the pursuit of pleasure, connectedness to nature, smartphone addiction. This study indicated that:(1) Self-regulatory fatigue had a significantly positive prediction for smartphone addiction of undergraduate students; (2) The pursuit of pleasure of undergraduate students mediated the relationship between self-regulatory fatigue and smartphone addiction; (3) The relationship between self-regulatory fatigue and pursuit of pleasure was moderated by connectedness to nature. That is, with connectedness to nature being strengthen, the influence of self-regulatory fatigue on the smartphone addiction of undergraduate students was decreased. Therefore, there was a moderated mediation model between self-regulatory fatigue and smartphone addiction.
