Research that focuses on the relationship between interpersonal conflict at work (i.e., intragroup conflict and intergroup conflict) and depression that also considers differences in socioeconomic status (SES) is limited. The purpose of the current study is to investigate the relationship between interpersonal conflict at work and depression at different levels of SES. A cross-sectional study was conducted with a total of 17,390 males and 2923 females employed in nine factories located in several regions of Japan. These participants were surveyed using a self-administered questionnaire that included self-reported measures of interpersonal conflict at work (intragroup conflict and intergroup conflict), SES (education and occupation), worksite support (supervisor support and coworker support), depression (assessed using the Center for Epidemiologic Studies Depression [CES-D] scale), and other demographic covariates. Those who had scores of 16 + on the CES-D scale (4066 males and 873 females) were classified as experiencing depression. The association of interpersonal conflict with depression was significantly greater among males of a high SES (i.e., higher educational status and non-manual workers) than males of a low SES (i.e., lower educational status and manual workers) after adjusting for demographic variables, supervisor support, and coworker support. More specifically, the association of intergroup conflict with depression was significantly greater among males of a high SES than males of a low SES. However, this pattern was not observed in females. The current study suggests that males of a higher SES are more vulnerable to interpersonal conflict at work in terms of developing depression than males of a lower SES.
目前针对工作中人际冲突（即群体内冲突和群体间冲突）与抑郁之间关系的研究，大多都没有考虑到社会经济地位（SES）的差异。本研究旨在探讨不同 SES 水平下工作中人际冲突与抑郁之间的关系。采用横断面研究，共调查了日本九个地区九个工厂的 17390 名男性和 2923 名女性员工。这些参与者通过自我报告问卷进行调查，问卷内容包括工作场所人际冲突（群体内冲突和群体间冲突）、SES（教育和职业）、工作场所支持（主管支持和同事支持）、抑郁（使用流行病学研究中心抑郁量表评估）以及其他人口统计学协变量。CES-D 量表得分≥16 分（男性 4066 人，女性 873 人）的被诊断为患有抑郁。在校正了人口统计学变量、主管支持和同事支持后，高 SES（即较高教育程度和非体力劳动者）男性的人际冲突与抑郁之间的关联明显大于低 SES（即较低教育程度和体力劳动者）男性。具体而言，高 SES 男性的群体间冲突与抑郁之间的关联明显大于低 SES 男性。然而，这一模式在女性中并未观察到。本研究表明，与低 SES 男性相比，高 SES 男性更容易因工作中的人际冲突而患上抑郁。
