Background Sleep is associated with some behavioral factors such as maladaptive, which tend to disrupt its normal mechanism, therefore, a tool is needed to measure maladaptive sleep hygiene. This study aims to assess the psychometric properties of sleep hygiene index (SHI), translation, factor structure, validity, and reliability.Design and methods Data were collected from 101 Indonesia adolescents in junior high school, with SHI-Indonesia translated based on WHO guideline. The obtained data were analyzed using varimax rotation, while the convergent validity was evaluated by calculating the correlation between the item and total score. In addition, the Cronbach's alpha was computed to investigate internal consistency, and two-week interval test-retest was conducted to assess reliability.Results SHI is a unidimensional factor structure with an excellent test-retest reliability of P<0.001 at 0.618, and a positive convergent validity correlation between each item and the total score.Conclusions The SHI Bahasa translation is a reliable and valid tool to assess maladaptive sleep hygiene among Indonesia Adolescents.
