The purpose of the evaluation is to:
The Sleep Hygiene Index (SHI) is a 13-item self-administered index intended to assess the presence of behaviors thought to comprise sleep hygiene. Participants are asked to indicate how frequently they engage in specific behaviors (always, frequently, sometimes, rarely, never). Items constructing the Sleep Hygiene Index are derived from the diagnostic criteria for inadequate sleep hygiene in the International Classification of Sleep Disorders (American Sleep Disorders Association, 1990). Item scores were summed providing a global assessment of sleep hygiene. Higher scores are indicative of more maladaptive sleep hygiene status.
