To determine the prevalence of bedtime procrastination (BtP) among Indian university students and to evaluate the performance of the Bedtime Procrastination Scale (BPS). The BPS (scoring range, 9-45), with separate, additional questions related to sleep and influences thereon, was administered to all on-campus graduate and postgraduate students attending Navrachana University, Gujarat, India. The variable of regular sleep habits was defined as a BPS total score of 9-18 and BtP as a BPS total of 36-45. The BPS was examined using factor analysis. The study was conducted from November 2021 to December 2021. Completed forms were received from 560 of 567 eligible students. The mean BPS total score was 29.1. BPS total scores did not differ significantly between males and females. Few students (n = 54, 9.6%) had study-defined regular sleep habits. One-fifth of the sample (20.2%) had study-defined BtP. Higher BtP total scores showed a small but statistically significant correlation with daytime tiredness ( = 0.26). Factor analysis of the BPS yielded a 2-factor solution that explained 49.3% of the variance in the data. The latent variables appeared to represent "Going to bed late" and "Going to bed on time." Potential problems, not previously discussed in the literature, were identified based on the manner in which BPS items were presented and scored. Few university students have regular sleep habits. BtP is present in a sufficiently large enough proportion of students to be of health concern. The BPS is likely to require modifications for future use.
确定印度大学生中睡前拖延（BtP）的患病率，并评估睡前拖延量表（BPS）的性能。对印度古吉拉特邦纳夫拉查纳大学所有在校研究生和本科生施测BPS（评分范围为9 - 45），该量表还有与睡眠及其影响相关的单独附加问题。将规律睡眠习惯变量定义为BPS总分9 - 18，将BtP定义为BPS总分36 - 45。使用因子分析对BPS进行检验。研究于2021年11月至2021年12月进行。在567名符合条件的学生中，有560名提交了完整表格。BPS总分均值为29.1。男性和女性的BPS总分无显著差异。很少有学生（n = 54，9.6%）有研究定义的规律睡眠习惯。五分之一的样本（20.2%）有研究定义的BtP。较高的BtP总分与白天疲劳呈微弱但具有统计学意义的相关性（ = 0.26）。BPS的因子分析产生了一个双因子解决方案，解释了数据中49.3%的方差。潜在变量似乎代表“晚睡”和“按时上床睡觉”。根据BPS项目的呈现和评分方式，识别出了文献中此前未讨论过的潜在问题。很少有大学生有规律的睡眠习惯。BtP在足够大比例的学生中存在，值得关注健康问题。BPS未来使用可能需要修改。
