Psychometric Properties of Sleep Behavior Questionnaire among Bengali Population

Abstract

Aim: Numerous important biological functions in the human body are regulated by adequate amount of sleep. Manifestations of poor sleep are often misconceived as behavioural issues, cognitive dysfunction or systemic health concerns, which may present differently in adults and children. Sleep Behaviour Questionnaire (SBQ) is an assessment tool mostly filled by parents regarding their childs sleep behaviour and patterns. The present study aimed to assess the validity and reliability of the SBQ in relation to the Bengali population. Place and Duration: Department of Pediatric and Preventive Dentistry, Guru Nanak Institute of Dental Sciences & Research, Panihati, Sodepur, Kolkata from November 2020 till December 2020. Materials and Methods: SBQ was the assessment tool used. The original questionnaire was sent to a bilingual teacher (English-Bengali) for translation into Bengali (version1, V1). V1 was given to a Bengali language teacher for semantic correction and idiosyncratic variants (version 2, V2). In collaboration with a researcher and other mental health care professionals, V2 was compared to the final version of Bengali. The scale was then translated into the original (English) language. The final version was used for the study and was filled up by guardians of 50 children aged between 6 to 13 years. Data were tabulated and analyzed and the statistical methods used were Cronbachs alpha and Content Validity Ratio. Results: To ensure validity, Content Validity Ratio was checked and most items in the questionnaire were acceptable as per experts. To ensure reliability, Cronbachs alpha was calculated and the value was 0.778. Conclusion: The SBQ can be used with respect to the Bengali population as the findings support the psychometric properties of the questionnaire.
