The aim of this study was to investigate the amount and sources of stress in dental undergraduate students in Fujian, China, and the factors associated with stress.
This cross-sectional study was conducted during the second semester of the 2017-2018 academic year at the School of Stomatology, Fujian Medical University, China. A total of 396 students were surveyed with the Dental Environment Stress Questionnaire (DES) and the Perceived Stress Scale (PSS) using an online survey system. The participants' demographic information, including sex, age, year of study, and grade point average (GPA) was also collected. One-way analysis of variance (ANOVA) was performed to compare the stress scores. Pearson correlation and multiple linear regression analyses were conducted to explore the associated factors of stress and academic performance. All statistical analyses were performed at a significance level of 5%.
A total of 347 undergraduate students participated in the present study, for a response rate of 87.6%. There were no significant differences in the DES and PSS total scores among students of different grades and sexes. Significant differences were found in the DES "workload" and "self-efficacy beliefs" scores among students from different study years (all P < 0.05). The Multiple linear regression showed that DES and PSS scores were negatively correlated with GPA, while sex was positively correlated with GPA (all P < 0.05). Female students had significantly higher GPAs than male students.
Dental undergraduates in Fujian, China experienced moderate levels of stress. While the amount of stress did not differ by year of study, the sources of stress did differ. Stress scores and sex were negatively correlated with academic performance.
本研究旨在调查中国福建牙科学本科生的压力程度和来源，以及与压力相关的因素。
本横断面研究于 2017-2018 学年第二学期在中国福建医科大学口腔医学院进行。采用在线调查系统，用牙科环境应激问卷（DES）和应激知觉量表（PSS）对 396 名学生进行调查。还收集了学生的人口统计学信息，包括性别、年龄、年级和平均绩点（GPA）。采用单因素方差分析（ANOVA）比较应激评分。采用 Pearson 相关和多元线性回归分析探讨应激和学业成绩的相关因素。所有统计分析均在 5%的显著性水平上进行。
共有 347 名本科生参加了本研究，应答率为 87.6%。不同年级和性别的学生在 DES 和 PSS 总分上无显著差异。不同学习年限的学生在 DES“工作量”和“自我效能信念”评分上存在显著差异（均 P<0.05）。多元线性回归显示，DES 和 PSS 评分与 GPA 呈负相关，而性别与 GPA 呈正相关（均 P<0.05）。女生的 GPA 显著高于男生。
中国福建的牙科学本科生经历了中等程度的压力。虽然学习年限不同，压力程度没有差异，但压力来源不同。应激评分和性别与学业成绩呈负相关。
