Linguistic adaptation and psychometric evaluation of Italian version of children’s sleep habits questionnaire

Background: The Children’s Sleep Habits Questionnaire (CSHQ) is a parent-report questionnaire used to examine sleep behavior in children. Linguistic adaptation of CSHQ into several languages and/or psychometric analysis of reliability have been published. Main text: Our aim was to translate the original 33-items CSHQ from English to Italian and to examine its reliability for use in 4–10 years-old children of Italy. After translation and back-translation procedure of the original CSHQ, the Italian CSHQ (CSHQ-IT) was administered to 69 mothers of healthy children. Reliability of CSHQ-IT was examined by the internal consistency of the scale (using the Cronbach’s alpha coefficient), and by the test-retest analysis obtained by asking mothers who had completed the CSHQ-IT at baseline to re-complete it after a two-week interval (measured with the Lin’s Concordance Correlation Coefficient, CCC). The CSHQ-IT showed adequate internal consistency (Cronbach’s alpha = 0.81 for the total scale). The total CSHQ-IT score showed a strong correlation in retests (CCC 0.87; 95% Confidence Interval, 0.80; 0.92). Conclusion: CSHQ-IT is a valuable tool for evaluating sleep behavior in children 4–10 years-old in Italy. Future research should be implemented to provide definitive validity of CSHQ-IT in children with sleep-disordered breathing
