Abstract：
Internet addiction (IA) has become a global concern among college students. To explore the psychophysiological mechanism that is related to IA, this study investigated the role of resilience, loneliness, and resting respiratory sinus arrhythmia (RSA) in IA through a moderated mediation model. A group of 108 (Mage = 18.93, SD = 0.914; 68 male) Chinese undergraduate students completed questionnaires of resilience, loneliness, and IA. Physiological data were collected during their visit to a university laboratory. Results revealed that loneliness mediated the negative association between resilience and IA, with resting RSA and resilience interactively predicted loneliness. Specifically, resilience was negatively related to loneliness only when students had low, rather than high, levels of resting RSA. These findings enrich our understanding of how resilience is related to college students\' IA and highlight the protective role of resting RSA in this association.
摘要：
网络成瘾（IA）已成为全球大学生关注的问题。探讨与IA相关的心理生理机制，这项研究调查了韧性的作用，孤独,和静息呼吸性窦性心律失常（RSA）在IA中通过调节调解模型。一组108名（Mage=18.93，SD=0.914；68名男性）中国本科生完成了韧性问卷，孤独,和IA。生理数据是在他们访问大学实验室期间收集的。结果表明，孤独感介导了韧性与IA之间的负相关，休息RSA和韧性交互预测孤独。具体来说,只有当学生的孤独感很低时，弹性才与孤独感负相关，而不是高，restingRSA的水平。这些发现丰富了我们对复原力如何与大学生IA相关的理解，并强调了静息RSA在这种关联中的保护作用。
