Perfectionism and depressive symptoms are among psychological concerns in medical students with suicidal ideation. While studies suggest a link between perfectionism and depression, the role of mediating mechanisms remains unclear.
This study aimed to examine the mediating role of hopelessness and repetitive negative thinking in the relationship between perfectionism and depressive symptoms among Iranian medical students.
The research employed a descriptive-correlational design using structural equation modeling (SEM). The study population comprised all medical students in Tehran in 2024, from which 355 individuals were selected through purposive sampling. Data were collected using the Beck Scale for Suicidal Ideation (BSSI), Tehran Multidimensional Perfectionism Scale (TMPS), Beck Depression Inventory (BDI-II), Repetitive Negative Thinking Questionnaire (RNTQ), and the Beck Hopelessness Scale (BHS). The data were analyzed using structural equation modeling.
The results indicated that the proposed model demonstrated an excellent fit, and perfectionism was significantly and directly associated with depressive symptoms (p < 0.01). Additionally, perfectionism indirectly predicted depressive symptoms (p < 0.001) through hopelessness (β = 0.35) and repetitive negative thinking (β = 0.37). Together, perfectionism, hopelessness, and repetitive negative thinking accounted for 58% of the variance in depressive symptoms (R² = 0.58).
These findings suggest that perfectionism contributes to an increase in depressive symptoms both directly and indirectly, by intensifying feelings of hopelessness and repetitive negative thinking.
完美主义和抑郁症状是有自杀意念的医学生所面临的心理问题。虽然研究表明完美主义与抑郁之间存在联系，但中介机制的作用仍不明确。
本研究旨在探讨无望感和重复性消极思维在伊朗医学生完美主义与抑郁症状关系中的中介作用。
本研究采用描述性相关设计，运用结构方程模型（SEM）。研究对象为2024年德黑兰所有医学生，通过目的抽样选取355名个体。使用贝克自杀意念量表（BSSI）、德黑兰多维完美主义量表（TMPS）、贝克抑郁量表（BDI-II）、重复性消极思维问卷（RNTQ）和贝克无望感量表（BHS）收集数据。采用结构方程模型对数据进行分析。
结果表明，所提出的模型拟合良好，完美主义与抑郁症状显著直接相关（p < 0.01）。此外，完美主义通过无望感（β = 0.35）和重复性消极思维（β = 0.37）间接预测抑郁症状（p < 0.001）。完美主义、无望感和重复性消极思维共同解释了抑郁症状变异的58%（R² = 0.58）。
这些发现表明，完美主义通过加剧无望感和重复性消极思维，直接和间接地导致抑郁症状增加。
