Abstract

Background: Inappropriate sleep hygiene may result in disturbed daily functioning; therefore, the importance of using a sleep hygiene measurement scale is on the rise. The purpose of this study was to assess the reliability and validity of the Persian version of Sleep Hygiene Index (SHI) among the women of Kermanshah city.

Method: In this study, 455 women were randomly selected. Data were collected from the study samples by SHI, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale and Insomnia Severity Index. Twenty percent of participants recompleted the Sleep Hygiene Index after 4-6 weeks interval to measure test-retest reliability. Then, Pearson product-moment correlation coefficient between SHI and PSQI, ESS and ISI was computed. The factor structure of the SHI was evaluated by explanatory factor analysis.

Results: The internal consistency of the questionnaire was 0.83 (P<0.01) and Sleep Hygiene Index was found to have a good test-retest reliability (r= 0.84, P<0.01). Explanatory factor analysis indicated three factors, `sleep-wake cycle behaviors` (four items), `bedroom factors` (three items), and ‘behaviors affecting sleep`(six items). Moreover, SHI was positively correlated with the total score of Pittsburgh Sleep Quality Index (r=0.61, P<0.01), Epworth Sleepiness Scale (r=0.63, P<0.01) and Insomnia Severity Index (r=0.62, P<0.01).

Conclusion: The Persian version of SHI could be considered as a reliable and valid tool for evaluating sleep hygiene in Iranian women.
