A new questionnaire helps identify risk for delayed sleep phase disorder (DSPD). High risk for DSPD correlates with increased absenteeism and impaired daily functioning in work, social, and family life.
Area of Science:
- Sleep Medicine
- Psychiatry
- Public Health
Background:
- Delayed sleep phase disorder (DSPD) lacks a validated screening questionnaire, hindering diagnosis.
- Early detection is crucial for managing DSPD's impact on daily life.
Purpose of the Study:
- Develop and validate a screening questionnaire for DSPD risk.
- Assess the impact of DSPD risk on absenteeism and functioning.
Main Methods:
- Cross-sectional internet survey with 13,844 initial respondents.
- 1315 eligible participants completed the survey, including evening types and non-evening types.
- Assessed self-reported absenteeism and functioning in work/school, social, and family domains.
Main Results:
- 5.1% of respondents screened positive for high DSPD risk.
- High DSPD risk was significantly associated with increased absenteeism, reduced productivity, and disruptions.
- Daytime sleepiness and sleep deficits were more prevalent in high-risk individuals.
Conclusions:
- DSPD risk is linked to significant negative impacts on work, social, and family life.
- The developed questionnaire aids in identifying individuals at risk for DSPD.
- Screening for DSPD is essential for improving patient outcomes and daily functioning.
