Area of Science:

  • Psychology
  • Health Sciences
  • Medical Assessment

Background:

  • Sleep quality significantly impacts overall health and life satisfaction.
  • Individual factors influencing sleep quality necessitate personalized assessment methods.
  • Existing sleep quality questionnaires lack comprehensiveness.

Purpose of the Study:

  • To develop a novel instrument for measuring sleep quality.
  • To evaluate the validity and reliability of the new scale.
  • To provide a comprehensive tool for sleep quality assessment.

Main Methods:

  • Development of the Sleep Quality Scale (SQS) using item and factor analysis.
  • Assessment of construct validity by comparing scores between insomniacs and normal subjects.
  • Evaluation of concurrent validity through correlation with the Pittsburgh Sleep Quality Index.
  • Determination of internal consistency and test-retest reliability.

Main Results:

  • The 28-item SQS, comprising six factors, explained 62.6% of the total variance.
  • Significant differences in SQS scores confirmed construct validity (t = -13.8, P = 0.000).
  • Strong correlation with the Pittsburgh Sleep Quality Index indicated concurrent validity (r = 0.72, P = 0.000).
  • High internal consistency (Cronbach's alpha = 0.92) and test-retest reliability (r = 0.81) were observed.

Conclusions:

  • The developed Sleep Quality Scale (SQS) is a valid and reliable instrument.
  • SQS offers a comprehensive approach to assessing individual sleep quality.
  • This scale can be a valuable tool in clinical and research settings for sleep evaluation.
