The “abbreviated” version of the questionnaire contains the 33 items that were used for scoring. Total CSHQ score and 8 subscale scores can be calculated, and a higher score is indicative of more sleep problems. This structure was originally validated for children aged 4 to 10 years old but the questionnaire has also been used for younger 2 to 3 years old children.
The “longer” version of the CSHQ also contains additional items which, although not utilized in either the subscale or total scores, may yield clinically relevant information.
The CSHQ-PT project (Portuguese version of the CSHQ) started in 2009 with a preliminary contact with Prof. Judith Owens that welcomed the initiative. The cross-cultural adaptation of the long version of the questionnaire was made according to published international guidelines and the back translation was approved by the author in 2010. Thereafter the CSHQ-PT was validated for children aged 2 to 10 years old and the first results were presented at the 5th Europaediatrics Congress in June 2011 showing that the CSHQ-PT psychometric properties are similar to the versions from other countries and adequate for research (1,2).
The Portuguese version of the CSHQ is available in this page (portuguese).
