From: Validation of the Farsi version of the revised Adolescent Sleep Hygiene Scale (ASHSr): a cross-sectional study

  1. Note. Higher scores in the ASHSr reflect better sleep hygiene practices. Higher scores in the PSQI indices represent lower sleep quality. Therefore, negative correlations indicate that better sleep hygiene practices are associated with better quality of sleep
