Association Between Introversion Personality and Social Media Usage-Related Social Anxiety Among Chinese College Students: Chain Mediating Effects of Interaction Anxiousness and Mobile Phone Addiction.

内容摘要

BACKGROUND AND OBJECTIVE: Social anxiety arising from intensive social media usage (SMU) among adolescents and youth has gained extensive attention in recent years due to its negative influence on mental health and academic performance. In spite of that, there is a dearth regarding the etiology of SMU-related social anxiety. This study aims to further clarify the influence of introversion personality on SMU-related social anxiety and the mechanism underlying such an association and provide a new perspective for developing effective intervention strategies for the highly prevailing SMU-related anxiety among Chinese college students. METHODS: A cohort of 979 college students (266 males and 713 females) aged 20.90 ± 1.91 years was enrolled in this cross-sectional study. Four measures including the "extroversion" domain of Eysenck Personality Questionnaire Revised, Short Scale (EPQ-R-S E), Interaction Anxiousness Scale (IAS), Mobile Phone Addiction Index (MPAI), and Social Anxiety Scale for Social Media Users (SAS-SMU) were used to evaluate the influence of introversion personality on SMU-related social anxiety that was potentially mediated sequentially by interaction anxiousness and mobile phone addiction. Hayes PROCESS was used for correlation and mediation analysis. RESULTS: Interaction anxiousness (indirect effect = -1.331, 95% CI : -1.559 - -1.122) partially mediated the association between introversion personality and SMU-related social anxiety. Besides, a sequential mediation of interaction anxiousness and mobile phone addiction in the link between introversion personality and SMU-related social anxiety was revealed (indirect effect = -0.308, 95% CI : -0.404 - -0.220). No significant mediating effect was found with mobile phone addiction in the association between introversion personality and SMU-related social anxiety. CONCLUSION: Targeting interaction anxiousness and mobile phone addiction may represent an efficient strategy alleviating SMU-related social anxiety among Chinese college students with introversion personality. 背景和目的: 近年来，密集的社交媒体使用（social media usage，SMU）在青少年和青年群体中引发了日益普遍的社交焦虑问题，对他们的心理健康和学业均产生了负面影响。然而，目前对引发SMU相关社交焦虑的原因尚缺少了解。本研究旨在进一步阐明内向人格对与SMU相关的社交焦虑的影响及其潜在机制，并为针对中国大学生中普遍存在的与SMU相关的焦虑制定有效干预策略提供新的视角。方法: 本研究为横断面研究，研究对象为979名大学生（266名男生和713名女生），平均年龄为20.90± 1.91岁。问卷调查采用艾森克人格简短量表（Eysenck Personality Questionnaire Revised，Short Scale，EPQ-R-S E）中的“外向性”维度、交往焦虑量表（Interaction Anxiousness Scale，IAS）、手机成瘾指数量表（Mobile Phone Addiction Index，MPAI）以及SMU相关社交焦虑量表（Social Anxiety Scale for Social Media Users，SAS-SMU），以评估内向人格通过交往焦虑和手机成瘾对SMU相关社交焦虑的链式中介作用。使用Hayes PROCESS进行相关性和中介效应分析。结果: 交往焦虑（间接效应=-1.331，95% CI:-1.559~-1.12）部分中介了内向人格与SMU相关社交焦虑之间的关联。此外，交往焦虑和手机成瘾在内向人格与SMU相关社交焦虑间存在链式中介作用（间接效应=-0.308，95% CI:-0.404~-0.220）。在内向人格与SMU相关社交焦虑之间的关联中，未发现手机成瘾有显著的中介作用。结论: 针对性改善具有内向人格的青少年社交焦虑和手机成瘾可能是减轻SMU相关社交焦虑的一种有效策略。.
