Previous research has indicated that personality traits, loneliness, and problematic internet use (PIU) significantly contribute to the prevalence of adolescent depression. However, the specific interrelationships among these variables in explaining the occurrence of depression remain unclear. Drawing upon susceptibility theory and cognitive-behavioral theory, this study explored whether personality traits influences adolescent depression through loneliness and PIU.
A total of 2476 adolescents (aged 12-18) from all over the country completed a psycho-social test, including the 10-Item Big Five Personality Inventory (BFI-10), three-Item Loneliness Scale (T-ILS), Problematic Internet Use Questionnaire-Short Form (PIUQ-SF-6) and the Patient Health Questionnaire-9 (PHQ-9). The mediation model was built and bootstrap method was used to test the mediating effect.
Results showed that neuroticism, conscientiousness, openness, and agreeableness have a direct role on depression. Loneliness and PIU partially mediated the relationship between neuroticism, conscientiousness, agreeableness and depression, and completely mediated the relationship between extroversion and depression.
The results suggest that loneliness and PIU play important mediating roles in the relationship between personality traits and depression. This remind us that alleviating sense of loneliness and reducing overuse of the internet are a strategy for improve depression among adolescents.
先前的研究表明，人格特质、孤独感和网络成瘾问题（PIU）显著影响青少年抑郁的发生率。然而，这些变量在解释抑郁发生方面的具体相互关系仍不清楚。本研究基于易感性理论和认知行为理论，探讨了人格特质是否通过孤独感和 PIU 影响青少年抑郁。
本研究共纳入来自全国各地的 2476 名青少年（年龄 12-18 岁），他们完成了一项心理社会测试，包括 10 项大五人格量表（BFI-10）、三项目孤独感量表（T-ILS）、问题性互联网使用问卷-简化版（PIUQ-SF-6）和患者健康问卷-9（PHQ-9）。建立了中介模型，并使用自举法检验了中介效应。
结果表明，神经质、尽责性、开放性和宜人性直接影响抑郁。孤独感和 PIU 部分中介了神经质、尽责性、宜人性与抑郁之间的关系，完全中介了外向性与抑郁之间的关系。
研究结果表明，孤独感和 PIU 在人格特质与抑郁之间的关系中起着重要的中介作用。这提醒我们，减轻孤独感和减少互联网过度使用是改善青少年抑郁的一种策略。
