ABSTRACT

The aim of this study was twofold. Firstly, it explored the relationships between morningness, Big Five personality traits, depression, and problematic Internet use (PIU). Secondly, it examined the possible mediating role of depression in these relationships. The following measures were used: the Internet Addiction Test, the Composite Scale of Morningness, the International Personality Item Pool–Big Five Markers–20, and the Center for Epidemiologic Studies Depression Scale. The participants in the study were 398 university students 18 to 30 (M = 20.37, SD = 2.29) years of age. The study found that PIU Total, PIU Mental Disorder, and PIU Time Management Disorder are positively related to depression and negatively related to morningness, Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Openness. PIU was more often found in individuals with an evening chronotype. The study confirmed the role of depression as a mediator in the relationship of personality traits and morningness to PIU Mental Disorder and PIU Time Management Disorder. For PIU Mental Disorder, the study revealed a full mediation effect of depression in the case of morningness, Emotional Stability, and Extraversion, and partial mediation in the case of Agreeableness and Intellect. For PIU Time Management Disorder, there was a full mediation effect of depression in the case of Emotional Stability, Extraversion, and Agreeableness, and partial mediation in the case of morningness and Intellect. The results highlight the importance of including depression when investigating the relationship between morningness and personality in studies of PIU.

摘要

这项研究的目的是双重的。首先，它探讨了早起、大五人格特质、抑郁和有问题的互联网使用 (PIU) 之间的关系。其次，它研究了抑郁在这些关系中可能的中介作用。使用了以下措施：网络成瘾测试、晨曦综合量表、国际人格项目库 - 大五标志 - 20和流行病学研究中心抑郁量表。该研究的参与者是 398 名 18 至 30 岁的大学生（M = 20.37，SD = 2.29) 岁。研究发现，PIU Total、PIU 精神障碍和 PIU 时间管理障碍与抑郁呈正相关，与早恋、外向性、宜人性、责任心、情绪稳定性和开放性呈负相关。PIU 更常见于晚间型的个体。该研究证实了抑郁症在人格特质和早睡与 PIU 精神障碍和 PIU 时间管理障碍的关系中的中介作用。对于 PIU 精神障碍，该研究揭示了抑郁在晨起、情绪稳定和外向的情况下的完全中介作用，以及在宜人性和智力的情况下的部分中介作用。对于 PIU 时间管理障碍，在情绪稳定、外向性、宜人性，以及早晨和智力的部分调解。结果强调了在 PIU 研究中调查早起与性格之间的关系时包括抑郁症的重要性。
