Abstract

Objective: To perform cross-cultural adaptation of the Dental Environment Stress (DES), to test its construct validity and reliability, and to identify the sources of stress among Brazilian dental students. Material and Methods: The DES was transculturally adapted to Portuguese using translation/back-translation, review by an expert bilingual committee and consensus building. The first version was tested in a sample of 42 dental students to check the understanding level of the alternatives. The final version was applied to all the students enrolled in a Brazilian Public Dental School. Construct validity was assessed through factor analysis, performed by principal components analysis and Varimax rotation and reliability by internal Cronbach’s alpha coefficient (95% CI). Wilcoxon rank sum was conducted to test for gender and Kruskall-Wallis for year comparison. Multivariate analysis relied on ordinal logistic regression modeling. Results: Factor analysis revealed five factors that possessed eigenvalues greater than 1.5 and together explained 46.88% of the total variance. Internal consistency of each factor was adequate, with Cronbach's alpha ranging from 0.65 to 0.84.  ‘Examinations and grades’ (82.80%) was the highest scored item. Females presented higher rates, as well as second’s and fifth’s years students. The entering students were generally concerned with factors related to “Academic Performance”, whereas clinical year students with “Insecurity Concerning their Professional Future”. Conclusion: The Portuguese version of the DES presented good results, thus it could be a valid instrument to assess the factors of perceived stress in Lusophone countries, subsidizing the development of strategies to minimize the stress and optimize school performance.
葡语牙科学生口腔环境压力调查
目的:对牙科环境压力(DES)进行跨文化适应,检验其结构效度和信度,并确定巴西牙科学生的压力来源。材料和方法:通过翻译/反翻译,由双语专家委员会审查和建立共识,将DES跨文化地改编为葡萄牙语。第一个版本在42名牙科学生的样本中进行了测试,以检查他们对替代方案的理解程度。最终版本适用于巴西公立牙科学校的所有学生。通过因子分析评估结构效度,主成分分析和Varimax旋转评估结构效度,内部Cronbach 's alpha系数(95% CI)评估结构信度。采用Wilcoxon秩和检验性别,采用Kruskall-Wallis进行年度比较。多变量分析依赖于有序逻辑回归模型。结果:因子分析显示有5个因子的特征值大于1.5,解释了总方差的46.88%。各因子的内部一致性较好,Cronbach's alpha在0.65 ~ 0.84之间。“考试和成绩”(82.80%)是得分最高的项目。女生的比例更高,二年级和五年级的学生也是如此。初入大学的学生普遍关心“学业成绩”相关因素,而临床年级的学生则关心“对职业前途的不安全感”。结论:葡萄牙语版的DES结果良好,因此它可以作为评估葡语国家学生感知压力因素的有效工具,为制定减少压力和优化学校表现的策略提供资助。
