The Pittsburgh Sleep Diary (PghSD) effectively quantifies sleep and waking behaviors. This validated instrument shows reliability and sensitivity in diverse populations, correlating well with objective sleep measures.

Area of Science:

  • Sleep Science
  • Behavioral Science
  • Psychometrics

Background:

  • Comprehensive documentation of sleep and waking behaviors is crucial for research and clinical practice.
  • Existing methods may lack the detailed, user-friendly approach needed for daily monitoring.
  • The Pittsburgh Sleep Diary (PghSD) was developed to address this need.

Purpose of the Study:

  • To demonstrate the usefulness, validity, and reliability of the Pittsburgh Sleep Diary (PghSD).
  • To assess the PghSD's sensitivity to various demographic and individual difference factors.
  • To compare PghSD measures with objective sleep assessments and other questionnaires.

Main Methods:

  • Collected two-week PghSD data from 234 subjects across different age groups, genders, and clinical statuses.

  • Compared PghSD data with polysomnography, actigraphy, personality, and circadian type questionnaires.
  • Assessed test-retest reliability of PghSD measures over a 12-31 month period.

    • Main Results:

    • The PghSD demonstrated sensitivity to differences related to weekends, age, gender, personality, and circadian type.
    • PghSD measures showed validity by agreeing with actigraphic estimates of sleep timing and quality.
    • High test-retest correlations (0.56-0.81) for sleep timing and quality indicate strong reliability over time.

    Conclusions:

    • The Pittsburgh Sleep Diary (PghSD) is a useful, valid, and reliable instrument for quantifying sleep and waking behaviors.
    • The PghSD can differentiate sleep patterns based on various influencing factors.
    • The diary's robust psychometric properties support its application in research and clinical settings.
