• Abstract: 目的：探究研究生抑郁情绪的潜在类别，并分析不同类别抑郁情绪在自杀风险上的差异。方法：采用整群抽样法选取某高校9515名研究生，使用抑郁自评量表和中国大学生心理健康筛查量表中的自杀意图指标进行问卷调查。采用潜在剖面分析对研究生抑郁情绪进行分类，运用BCH卡方检验法探讨抑郁情绪潜在类别与自杀风险的关系。结果：研究生抑郁情绪存在3种潜在类别：C1低抑郁波动组、C2无抑郁组和C3低抑郁稳定组。研究生抑郁情绪的潜在类别在自杀风险上存在显著差异（χ2=177.05，p<0.001）。多重比较结果显示，C3低抑郁稳定组的自杀风险最高，C2无抑郁组次之，C1低抑郁波动组最低。结论：研究生抑郁情绪具有显著的群体异质性和个体差异性，C3低抑郁稳定组是自杀风险的高危群体。
• Objective: To understand the categorical characteristics of postgraduate’s depression and analyze the differences in suicide risk among potential categories of depression. Methods: A cluster sampling method was used to select 9515 postgraduate students from a certain university, and a questionnaire survey was conducted with the depression self-rating scale and the suicidal intention indicators in the college students mental health screening scale. Using latent profile analysis to classify depression emotions among postgraduate students, and Chi-square test with BCH method was used to explore the relationship between demographic characteristics and suicide risk. Results: The depression of postgraduates could be divided into C1 low depression fluctuation group, C2 non-depression group and C3 low depression stable group. There were significant differences in the suicide risk of the potential category of depression among postgraduate students（χ2=177.05, p<0.001）, with the highest suicide risk in the C3 low depression stable group, followed by the C2 non-depression group, and the lowest in the C1 low depression fluctuation group. The results of multiple comparisons showed that the risk of suicide was highest in the C3 low depression stable group, followed by the C2 non-depression group, and the C1 low depression fluctuation group was the lowest. Conclusion: There is significant group heterogeneity and individual differences in depression among postgraduate students, and the C3 low depression stable group is a high-risk group for suicide.
