Abstract

The study aimed to investigate the factorial structure, reliability, and validity of the Bengali version of the brief Questionnaire on Smoking Urges (QSU-Brief) tool in a sample of Bangladeshi smokers. The Bengali version QSU-Brief scale’s reliability and validity were assessed on the basis of the data provided by 460 Bangladeshi smokers. To substantiate the data reliability, internal consistency and test-retest reliability were measured. Exploratory factor analysis (EFA), followed by confirmatory factor analysis (CFA), was conducted to validate the psychometric properties of the 10-item-QSU-Brief tool. The questionnaire showed good internal consistency (Cronbach’s α = 0.94; Intraclass correlation coefficient = 0.91; p<0.001). The EFA and CFA confirmed that a two-factor solution explained 75.1% of the total variance and considered the best item structure of the Bengali version of QSU-Brief across the current study setting. The first factor reflected a strong desire to smoke, which comprised items 1, 2, 3, 5, 6, 9, and 10. While the second factor displayed expectation of relief from the negative implications, which contained items 4, 7, and 8. The study findings showed that the Bengali QSU-Brief had good reliability, validity, and factorial structure. Therefore, this tool could be an excellent candidate to evaluate smoking urges in Bangladeshi settings.
