Validity and reliability related to the Persian version of the Children's Sleep Habits Questionnaire

Considering insomnia as a common health issue, it is essential to access valid assessment tools for sleep evaluations and research in all societies. For this purpose, we aimed to evaluate the cross-cultural validation and psychometric properties of the Persian version related to the Children's Sleep Habits Questionnaire CSHQ in Iranian children. This study was conducted on 300 parents of primary school children aged 7-12 years in Kashan city. Reliability was assessed using Cronbach's alpha coefficient. Construct validity was evaluated by factor analysis. The Spearman correlation coefficient was also applied to examine the convergence and divergence validity. The Cronbach's alpha coefficient was 0.80 for the entire questionnaire. There was a positive correlation between the results from CSHQ and Bear's. The range of convergence validity was 0.4 to 0.86. The range of divergence validity was 0.006 to 0.66. Factor analysis showed that eight factors had the special value (with eigenvalue >1), which means that the 33 questions are summarized in eight dimensions. Our findings imply good reliability and validity of the CSHQ in the Iranian society.
