Being discriminated against is a potential interpersonal factor leading to suicidal ideation. Compared to nonimpoverished students, impoverished students have disadvantages in different aspects, leading to high risks of negative psychological states. However, few studies have contrasted the mechanism of discrimination in suicidal ideation between impoverished and nonimpoverished college students. The present study aimed to contrast the mediating effects of social support, depressive symptoms, and nonsuicidal self-injury (NSSI) between perceived discrimination and suicidal ideation among impoverished and nonimpoverished college students.
The convenience cluster sampling method was used. A total of 1897 Chinese college students (1084 female; M = 19.93, SD = 1.44) participated in the two-wave survey with a six-month interval.
Perceived discrimination significantly predicted suicidal ideation. Social support, depressive symptoms, and NSSI acted as mediators. However, the structural weights were significantly different between impoverished and nonimpoverished students. Specifically, the role of social support was more significant among impoverished students, while the role of depressive symptoms was more significant among nonimpoverished students.
Discrimination is a risk factor leading to suicidal ideation for college students. To intervene in suicidal ideation caused by discrimination, school and social workers should pay extra attention to reduce stress and increase social support for impoverished students.
遭受歧视是导致自杀意念的一个潜在人际因素。与非贫困学生相比，贫困学生在不同方面处于劣势，导致出现消极心理状态的风险较高。然而，很少有研究对比贫困和非贫困大学生在自杀意念方面的歧视机制。本研究旨在对比贫困和非贫困大学生在感知到的歧视与自杀意念之间，社会支持、抑郁症状和非自杀性自伤（NSSI）的中介作用。
采用便利整群抽样法。共有1897名中国大学生（1084名女性；M = 19.93，SD = 1.44）参与了间隔六个月的两波调查。
感知到的歧视显著预测了自杀意念。社会支持、抑郁症状和NSSI起到了中介作用。然而，贫困和非贫困学生之间的结构权重存在显著差异。具体而言，社会支持在贫困学生中的作用更为显著，而抑郁症状在非贫困学生中的作用更为显著。
歧视是导致大学生自杀意念的一个风险因素。为了干预由歧视引起的自杀意念，学校和社会工作者应格外注意减轻压力，并为贫困学生增加社会支持。
