Psychosocial Features of Shift Work Disorder

Area of Science:

• Occupational Health
• Sleep Medicine
• Psychosocial Research

Background:

• Shift Work Disorder (SWD) presents challenges for night workers, impacting sleep quality and daily functioning.
• Understanding the interplay between work schedules, sleep patterns, and psychosocial well-being is crucial for managing SWD.

Purpose of the Study:

• To investigate insomnia, sleepiness, and psychosocial characteristics in night workers with and without SWD.
• To compare night workers to day workers with and without insomnia.

Main Methods:

• Observational study involving 79 night workers and 40 day workers.
• Diagnostic interviews for sleep disorders and psychopathologies, questionnaires, and 14-day sleep diaries were utilized.
• Two-way ANCOVAs analyzed psychosocial variables, with effect sizes calculated.

Main Results:

• Distinct worker groups emerged based on clinical evaluation.
• Shift Work Disorder (SWD) was characterized by high total wake time and low total sleep time, with persistent sleepiness.
• Cognitive activation levels differentiated night worker groups; other psychosocial differences were smaller than those in day workers.

Conclusions:

• Shift Work Disorder (SWD) evaluation necessitates a comprehensive approach, considering all sleep periods.
• Key indicators for SWD assessment include self-reported total wake time, state sleepiness, and cognitive activation levels.
