Background: Pittsburgh Sleep Quality Index (PSQI) assesses perceived quality of sleep. Bengali is the 6th language in the world according to the number of first language speakers. PSQI is presently not available in Bengali. Poor quality of sleep affects work efficiency and health of individual and it is increasing in urban as well as in rural population. Aim: The aim of the study was (1) to adapt PSQI in Bengali Language and (2) to find the prevalence rate of poor quality of sleep among urban and rural populations and to compare the rate. Materials and Methods: First, Bengali PSQI (BPSQI) was adapted by linguistic validation methods. Then, a cross-sectional survey was conducted among sample in a municipal ward and in a village by BPSQI. The prevalence of poor sleep quality among the sample was ascertained. Data were presented in percentage, mean and standard deviation. Chi-square test and unpaired t-test were used according to necessity with α = 0.05. Results: Adapted BPSQI instrument was found of acceptable internal consistency (Cronbach's α = 0.816). The prevalence rate of poor sleep quality in urban adult population was 42.58% and rural population was 35.89% (χ2 = 4.004, P = 0.0454). Adult females in urban area showed more prevalence rate of poor sleep quality (58.74%) than those of adult females in rural area (45.96%). Conclusion: Adapted BPSQI can be used as a self-administered questionnaire among Bengali native speakers. A significant percentage of urban and rural adult population suffers from poor quality of sleep. Adult population in urban area, especially adult females, suffers more from poor quality of sleep than rural population.
