The absence of a screening questionnaire for delayed sleep phase disorder (DSPD) remains a barrier to its detection and subsequent clinical evaluation. We developed a questionnaire to screen for DSPD risk and assessed its impact on self-reported absenteeism and functioning in work/school, social, and family life.
Cross-sectional, with 13,844 individuals responding to a survey through an Internet survey provider, from which 1315 completed surveys were obtained from eligible participants.
A total of 1315 individuals who self-identified as evening type (n=979) or as non-evening type (n=356).
A total of 295 participants were at high risk for DSPD, which is 5.1% of the total eligible survey respondents and 22.4% of our final sample with completed surveys. Compared to those who were not at high risk for DSPD, those who were at high risk were more likely to report frequent absenteeism, frequent loss of productivity, disruption to work or school activities, disruption to social life or leisure activities, and disruption to family life or home responsibilities. Difficulty with daytime sleepiness was more common in those at high risk for DSPD than those who were not. Increased sleep deficit on nights before school or work was also associated with more frequent difficulties with daytime sleepiness; 15.4% of those with no sleep deficit reported always or usually having difficulties with daytime sleepiness compared to 55.7% of those with a sleep deficit of 3hours or more.
DSPD risk is associated with increased absenteeism and impaired functioning in work/school, social, and family life.
缺乏用于筛查延迟睡眠相位障碍（DSPD）的问卷仍然是其检测及后续临床评估的障碍。我们编制了一份问卷来筛查DSPD风险，并评估其对自我报告的缺勤情况以及在工作/学业、社交和家庭生活中的功能的影响。
横断面研究，13844人通过互联网调查提供商对一项调查做出回应，从符合条件的参与者中获得了1315份完整的调查问卷。
总共1315名自我认定为夜型（n = 979）或非夜型（n = 356）的个体。
共有295名参与者存在DSPD高风险，占符合条件的调查受访者总数的5.1%，占我们最终完成调查问卷样本的22.4%。与DSPD低风险者相比，高风险者更有可能报告频繁缺勤、频繁生产力下降、工作或学校活动受到干扰、社交生活或休闲活动受到干扰以及家庭生活或家庭责任受到干扰。白天嗜睡困难在DSPD高风险者中比非高风险者更常见。上学或上班前一晚睡眠不足增加也与白天嗜睡困难更频繁相关；无睡眠不足者中有15.4%报告总是或通常存在白天嗜睡困难，而睡眠不足3小时或更长时间者中这一比例为55.7%。
DSPD风险与缺勤增加以及工作/学业、社交和家庭生活功能受损有关。
