The SLEEP-50 questionnaire shows promise for identifying various sleep disorders. This tool can help screen for common sleep conditions in the general population.

Area of Science:

  • Psychiatry
  • Sleep Medicine
  • Psychometrics

Background:

  • Sleep disorders are prevalent and impact public health.
  • Accurate screening tools are essential for early detection and intervention.
  • The Diagnostic and Statistical Manual of Mental Disorders (DSM) provides diagnostic criteria for sleep disorders.

Purpose of the Study:

  • To evaluate the initial psychometric properties of the SLEEP-50 questionnaire.
  • To determine the SLEEP-50's effectiveness in detecting sleep disorders.
  • To assess the questionnaire's reliability and validity.

Main Methods:

  • The study involved 377 college students, 246 sleep patients, 32 nightmare sufferers, and 44 healthy volunteers.
  • Internal consistency was assessed using Cronbach's alpha (α = .85).

  • Test-retest reliability was examined, yielding correlations between .65 and .89.
  • Principal component analysis with direct oblimin rotation was performed.
  • Sensitivity, specificity, and kappa agreement (κ = .77) were calculated.

    • Main Results:

    • The SLEEP-50 demonstrated high internal consistency (Cronbach's alpha = .85).
    • Test-retest correlations ranged from .65 to .89, indicating good reliability.
    • The factor structure aligned with the designed structure.
    • Sensitivity and specificity scores were promising across all assessed sleep disorders.
    • Substantial agreement was found between clinical diagnoses and SLEEP-50 classifications (kappa = .77).

    Conclusions:

    • The SLEEP-50 questionnaire exhibits favorable initial psychometric properties.
    • The findings suggest the SLEEP-50 is effective in detecting a variety of sleep disorders.
    • The SLEEP-50 can serve as a valuable screening tool for common sleep disorders in the general population.
