Stress and its association with academic performance among dental undergraduate students in Fujian, China: a cross-sectional online questionnaire survey

Abstract

Background: 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. Methods: 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%. Results: 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. Conclusions: 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.

Perceived Stress Among Chinese Medical Students Engaging in Online Learning in Light of COVID-19

“…This result seemed consistent with another Chinese study that noted that the strongest stressor among Chinese dental students was “performance pressure”, specifically, fear of examinations, competition with peers, and uncertainty about the future. 51 This result suggested that “academic performance” and “career expectations” may be sustained demands or challenges among Chinese medical school students. In addition, health-related stressors were also proposed by our participants.…”

“…Deve ser pontuado que o estresse e a exaustão emocional podem levar ao desenvolvimento da Síndrome de Burnout e influenciar negativamente no desempenho das atividades acadêmicas do curso e na qualidade do tratamento ao paciente (Jiménez-Ortiz et al, 2019). Procedimentos direcionados para reduzir o estresse são indicados, visando à melhoria no desempenho do estudante (Lin et al, 2020).…”

New psychometric evidences on the Dental Environment Stress questionnaire among Romanian students

“…Over the past 35 years, research studies showed a significant amount of stress experienced by undergraduate dental students. [ 1 2 3 4 5 ] In order to address the educational psychological, and social needs of their students, teachers should be aware of the main sources of stress and its impact on academic performances or well-being. Thus, the evaluative feedback from dental students enables to improve the education performance.…”
