This study introduces a new method for test equating sleep functions, enabling score comparability across different sleep assessment tools. The novel methodology, combined with the International Classification of Functioning, Disability and Health (ICF), facilitates clinical and research result comparisons.

Area of Science:

  • Psychometrics
  • Health Sciences
  • Sleep Research

Background:

  • Score comparability across different instruments is often limited.
  • Test equating methodologies are crucial for comparing scores from various assessments.
  • The domain of sleep functions has seen limited score comparability studies.

Purpose of the Study:

  • To illustrate a novel test equating methodology applied to sleep functions.
  • To establish score comparability for instruments assessing sleep.
  • To address the scarcity of score comparability studies in sleep research.

Main Methods:

  • Utilized eight scales from two cross-sectional self-report studies.
  • Employed the International Classification of Functioning, Disability and Health (ICF) for content comparability.

  • Assessed direct (common persons) and indirect (common item) equating using Leunbach's model, including fit tests and Standard Error of Equating (SEE).

    • Main Results:

    • All items were linked to the ICF 'Sleep functions' category (b134).
    • Leunbach's model successfully equated 15 of 16 direct pairs and 8 of 12 indirect pairs.
    • Provided raw score conversion tables for 23 equated pairs; SEE was higher for indirect equating.

    Conclusions:

    • Leunbach's equating model was successfully applied to the sleep functions domain.
    • The novel methodology, with the ICF, enables comparison of clinical and research outcomes in sleep.
    • Facilitates improved communication among clinicians regarding sleep assessment results.
