Depression, anxiety, and stress (DAS) have been linked to poor academic outcomes. This study explores the relationships among DAS, academic engagement, dropout intentions, and academic performance - measured by Grade Point Average (GPA) - in medical students. It aims to understand how these factors relate to each other and predict academic performance.
Data were collected from 351 medical students (74.9 % female) through an online survey. The average age was 20.2 years. Psychometric instruments measured DAS, academic engagement, and dropout intentions. Structural equation modeling was used to test the relationships between these variables and their prediction of GPA.
DAS was negatively associated with academic engagement β̂=-0.501p<0.001 and positively associated with dropout intentions β̂=0.340p<0.001. Academic engagement positively predicted GPA β̂=0.298p<0.001 and negatively associated with dropout intentions β̂=-0.367p<0.001. DAS had a nonsignificant direct effect on GPA β̂=-0.008p=0.912. However, the indirect effect of DAS - via academic engagement - on GPA and dropout intention was statistically significant.
The study's limitations include the use of a convenience sample and the collection of all variables, except GPA, at the same time point, which may affect the generalizability of the results.
The study supports the important role of DAS in its association with academic engagement and dropout intentions, which can predict GPA. Addressing DAS could enhance academic engagement and reduce dropout rates, leading to better academic performance.
抑郁、焦虑和压力（DAS）与学业成绩不佳有关。本研究探讨了医学专业学生的 DAS、学业投入、辍学意向与学业成绩（以平均绩点 GPA 衡量）之间的关系。目的是了解这些因素之间的相互关系，并预测学业成绩。
通过在线调查，从 351 名医学生（74.9%为女性）中收集数据。平均年龄为 20.2 岁。心理测量工具测量 DAS、学业投入和辍学意向。结构方程模型用于检验这些变量之间的关系及其对 GPA 的预测作用。
DAS 与学业投入呈负相关（β̂=-0.501，p<0.001），与辍学意向呈正相关（β̂=0.340，p<0.001）。学业投入与 GPA 呈正相关（β̂=0.298，p<0.001），与辍学意向呈负相关（β̂=-0.367，p<0.001）。DAS 对 GPA 没有显著的直接影响（β̂=-0.008，p=0.912）。然而，DAS 通过学业投入对 GPA 和辍学意向的间接影响是显著的。
本研究的局限性包括使用方便样本和所有变量（除 GPA 外）在同一时间点收集，这可能会影响结果的普遍性。
本研究支持 DAS 在与学业投入和辍学意向的关联中的重要作用，这些因素可以预测 GPA。解决 DAS 问题可以提高学业投入，降低辍学率，从而提高学业成绩。
