The association between quality of sleep and psychological distress among dental undergraduate students is a critical area of research due to the high levels of stress and demanding schedules these students face. The objective of this study was to determine the prevalence of sleep disturbance and psychological distress among undergraduate dental students.
In a cross-sectional study conducted among 104 first year dental undergraduate students for a period of 1 month, quality of sleep was analyzed. Prevalidated questionnaires of Pittsburgh Sleep Quality Index (PSQI) and Kessler's (K10) psychological distress scale were used to collect the data.
As per PSQI analysis, 43 students (43.1%) report good sleep quality (global score of 0-5), 52 students (51%) reports poor sleep quality (overall score of 6-10), and 7 students (6.9%) reports very poor sleep quality (overall score of 11-21). Responses from K10 revealed that 33 students (32.4%) are likely to be well (total score of 10-19), 23 students (22.5%) have mild psychological distress (total score of 20-24), 13 students (12.7%) have moderate psychological distress (total score of 25-29), and 33 students (32.4%) have severe psychological distress (total score of 30-50). F-Statistic, between and within groups was 0.0064 suggested significant differences in sleep quality across different psychological distress levels.
57.9% of the students reported poor sleep quality, with many experiencing sleep disturbances such as delayed sleep onset, reduced sleep duration, and daytime sleepiness. PSQI revealed that over half of the participants had poor or very poor sleep quality, while the K10 scale indicated that a significant portion of students experienced moderate to severe psychological distress. The results show that students facing severe psychological distress tend to have worse sleep quality, as evidenced by the statistically significant differences in sleep quality across distress levels.
由于牙科本科学生面临的高压力和紧张日程，睡眠质量与心理困扰之间的关联是一个关键的研究领域。本研究的目的是确定本科牙科学生睡眠障碍和心理困扰的患病率。
在一项对104名牙科本科一年级学生进行为期1个月的横断面研究中，分析了睡眠质量。使用匹兹堡睡眠质量指数（PSQI）和凯斯勒（K10）心理困扰量表的预验证问卷收集数据。
根据PSQI分析，43名学生（43.1%）报告睡眠质量良好（全球评分0 - 5），52名学生（51%）报告睡眠质量差（总评分6 - 10），7名学生（6.9%）报告睡眠质量非常差（总评分11 - 21）。K10的回答显示，33名学生（32.4%）可能状况良好（总评分10 - 19），23名学生（22.5%）有轻度心理困扰（总评分20 - 24），13名学生（12.7%）有中度心理困扰（总评分25 - 29），33名学生（32.4%）有重度心理困扰（总评分30 - 50）。组间和组内的F统计量为0.0064，表明不同心理困扰水平的睡眠质量存在显著差异。
57.9%的学生报告睡眠质量差，许多人经历睡眠障碍，如入睡延迟、睡眠时间缩短和日间嗜睡。PSQI显示，超过一半的参与者睡眠质量差或非常差，而K10量表表明相当一部分学生经历中度至重度心理困扰。结果表明，面临重度心理困扰的学生往往睡眠质量更差，不同困扰水平的睡眠质量存在统计学显著差异证明了这一点。
