Background: Inadequate sleep hygiene may result in difficulties in daily functioning; therefore, reliable scales for measuring sleep hygiene are important. Objectives: The purpose of this study was to assess the psychometric properties of the Persian version of the Sleep Hygiene Index (SHI). Results: The interclass correlation coefficient was 0.89, and SHI was found to have good test–retest reliability (r = 0.89, P < 0.01). The SHI was positively correlated with the total score of the PSQI (r = 0.60, P < 0.01), ESS (r = 0.62, P < 0.01) and ISI (r = 0.60, P < 0.01). Exploratory factor analysis extracted three factors, namely “sleep–wake cycle behaviors” (four items), “bedroom factors” (three items), and “behaviors that affect sleep” (six items). Conclusions: The Persian version of the SHI can be considered a reliable tool for evaluating sleep hygiene in the general population.
