The etiological factors of mood disorders and psychopathologies are understudied. In this paper, we explored whether social psychological strains are related to depression, anxiety, and stress in non-clinical populations.
6,305 college students (39.3% men; 60.7% women) from six Chinese provincial-level jurisdictions completed a paper-and-pencil survey with Psychological Strain Scales (PSS-40) and Depression, Anxiety, and Stress Scales-21 (DASS-21), both validated in Chinese populations.
Both PSS-40 and DASS-21 have high internal consistency reliabilities, and are highly correlated with each other. Hence, Chinese college students with greater psychological strains (value, aspiration, deprivation, or coping) have greater depression, anxiety, and stress. These results still held after controlling for relevant socio-demographic variables in the multiple regression models.
This was a cross-sectional study, and the sample only included several provinces in mainland China, not a representative sample of all of them.
Mood disorders and psychopathologies are linked to suicidal thoughts and behaviors. The results of this study extend the Strain Theory of Suicide from explaining the risk factors of suicidality to mood disorders and psychopathologies. Hence, these findings can inform prevention measures among college students, and possibly the general population.
心境障碍和精神病理学的病因因素研究不足。在本文中，我们探讨了社会心理压力是否与非临床人群中的抑郁、焦虑和压力有关。
来自中国六个省级行政区的 6305 名大学生（39.3%为男性；60.7%为女性）完成了一份有心理压力量表（PSS-40）和抑郁、焦虑和压力量表-21（DASS-21）的纸笔调查，这两个量表都在中国人群中得到了验证。
PSS-40 和 DASS-21 的内部一致性信度都很高，且彼此高度相关。因此，中国大学生的心理压力（价值、愿望、剥夺或应对）越大，抑郁、焦虑和压力就越大。在多元回归模型中控制了相关社会人口学变量后，这些结果仍然成立。
这是一项横断面研究，样本仅包括中国大陆的几个省份，而不是所有省份的代表性样本。
心境障碍和精神病理学与自杀意念和行为有关。本研究的结果将自杀的应激理论从解释自杀风险因素扩展到心境障碍和精神病理学。因此，这些发现可以为大学生和可能的普通人群提供预防措施的信息。
