Test-retest reliability of the Arabic version of the Pittsburgh Sleep Quality Index.

ABSTRACT: This study aimed to assess the test-retest reliability and validity of the Arabic version of the Pittsburgh Sleep Quality Index (A-PSQI), a 19-item sleep evaluation tool, in a population of medical students and interns in Saudi Arabia. Following a 16-person pilot study, 202 participants completed 2 A-PSQI questionnaires with a 2-week test-retest interval to avoid a carryover effect. Statistical analysis using RStudio included Cronbach alpha, Spearman rank correlation, and the intraclass correlation coefficient (ICC). The ICC results showed moderate to strong correlations in most PSQI components. The "Sleep efficiency" component had the lowest ICC (0.460), while "Sleep latency" had the highest (0.730). Overall, the PSQI reliability score is 0.694. Gender (sex assigned at birth) and academic
