Reliability and validity of instruments containing reported sleep measures among children from birth to <5 years of age: A systematic review.

Valid and reliable sleep measures during the early years are crucial for practitioners and researchers seeking accurate evaluation methods. The authors in this review systematically examined the psychometric properties of instruments containing reported sleep measures in children from birth to <5 years of age. The search was conducted using several electronic databases, including MEDLINE, EMBASE, PsycINFO, Web of Science, CINAHL, SPORTDiscus, Scopus and HaPI, with the most recent update on August 30, 2022. The quality of the included studies was assessed using the COSMIN methodology. A total of 79 studies were analyzed. However, none of these measures had undergone a comprehensive evaluation of all psychometric properties. Unfortunately, suitable reported sleep measures for children aged 0-4.99 years could not be identified through this review. Further research is needed to develop and validate psychometrically robust sleep assessment tools for this specific age group.
