Medical education can be a challenging and stressful process. Additional stressors can make the medical education process even more complex and impair a student's attention and concentration. To the authors' knowledge, there is no valid and reliable scale to measure medical school stress in Turkish medical students. Therefore, this study aimed to determine the validity and reliability of the Perceived Medical School Stress (PMSS) Scale in Turkish medical students. The Perceived Medical School Stress Scale is a self-assessment tool developed to measure medical school-induced stress in medical students. It consists of 13 items divided into two subdimensions. Scale items are answered using a four-point (0-4) Likert system The total score that can be obtained from the PMSS ranges from 0 to 52, with higher scores indicating higher levels of perceived stress. First, the scale was applied as a pilot to 52 students by performing the scale's back-and-forth translation into Turkish. Then, the scale was applied to 612 volunteer medical students to ensure validity. Convergent validity and confirmatory factor analysis are used to assess the construct validity of a scale. Test-retest, item correlations, and Cronbach's alpha coefficients are used to evaluate the reliability of a scale. As a result of confirmatory factor analysis, the two-factor structure of the original scale was confirmed. The fit indices of the model obtained showed excellent fit. The Generalized Anxiety Disorder-7 (GAD-7) Scale was used for convergent validity. The GAD-7 is a self-assessment tool that measures the level of generalized anxiety. It is answered with a four-point Likert scale for the last two weeks. The score that can be obtained from the scale is between 0-21. A score of ten or more indicates possible anxiety disorder. The students' mean perceived medical school stress score was 39.80±8.09, and their GAD-7 score was 11.0±5.5. A significant positive relationship was found between the total scores of the scales (r = .48, P < .001). The Cronbach's alpha value of the scale was .81, and test-retest reliability was significant for all scale items (P < .001 for all). No item was deleted according to Cronbach's alpha values and item-total correlations. There was no significant relationship between Turkish version of the PMSS and GAD-7 scores and age, sex, income status, tobacco use, or exercise (P>.05). The Turkish version of the Perceived Medical School Stress Scale is a valid and reliable scale that can be used to investigate the medical school-specific stress of students.
医学教育可能是一个具有挑战性和压力的过程。额外的压力因素可能会使医学教育过程更加复杂，并损害学生的注意力和专注力。据作者所知，目前没有有效的、可靠的量表可以衡量土耳其医学生的医学院压力。因此，本研究旨在确定感知医学院压力量表（PMSS）在土耳其医学生中的有效性和可靠性。感知医学院压力量表是一种自我评估工具，用于衡量医学生因医学院而产生的压力。它由 13 个项目组成，分为两个子维度。量表项目采用四点（0-4）李克特量表回答。PMSS 可获得的总分范围为 0 至 52，得分越高表示感知压力越高。首先，通过将量表反向翻译为土耳其语，对 52 名学生进行了初步测试。然后，向 612 名志愿医学生应用量表，以确保其有效性。采用收敛效度和验证性因素分析来评估量表的结构效度。重测信度、项目相关性和克朗巴赫 α 系数用于评估量表的可靠性。验证性因素分析的结果证实了原始量表的两因素结构。获得的模型拟合指数显示出极好的拟合度。采用广泛性焦虑障碍 7 项量表（GAD-7）进行收敛效度评估。GAD-7 是一种自我评估工具，用于衡量广泛性焦虑症的程度。它采用四点李克特量表回答过去两周的情况。量表的得分为 0-21。10 分或以上表示可能患有焦虑症。学生的平均感知医学院压力得分为 39.80±8.09，GAD-7 得分为 11.0±5.5。量表总分之间存在显著的正相关（r =.48，P <.001）。量表的克朗巴赫 α 值为.81，且所有量表项目的重测信度均显著（所有 P <.001）。根据克朗巴赫 α 值和项目总分相关性，没有删除任何项目。土耳其语版 PMSS 与 GAD-7 评分以及年龄、性别、收入状况、吸烟和运动之间无显著关系（P>.05）。土耳其语版感知医学院压力量表是一种有效且可靠的量表，可用于研究学生的医学院特定压力。
