Project Description

Author: Mahmood et al.


Poor sleep quality raises the morbidity burden of different diseases. To assess the quality of sleep is therefore essential and hence, a tool that could measure the problems is essential. To date, the available tool in Bangla is not appropriate to evaluate our patients and thus warranted. Therefore, this study is undertaken to develop a linguistically and culturally adapted, validated, and reliable Bangla version of the Pittsburgh Sleep Quality Index (PSQI). This will be a cross-sectional study conducted in the Basundhara Ad-din Medical College and Hospital, Dhaka. A total of 147 subjects aged more than 18 years of both sexes will be included according to inclusion & exclusion criteria. The original PSQI questionnaire will be translated into Bangla following established cross-cultural procedures. Reliability will be assessed for internal consistency and test-retest reliability by Chronbach’s Alpha coefficient and interclass correlation coefficient respectively. Validity will be assessed through face validity, content validity, and construct validity. Face validity will be assessed during the standard translation process. Content validity will be assessed by the content validity index (CVI). Spearman’s rank correlation coefficient will be used to assess convergent validity and The Kruskal-Wallis test will be used to assess known group validity. Factor analysis will be done by Principal Component Analysis with Varimax Rotation. The researcher will be duly careful about the ethical issues related to this study. Formal permission to undertake the study will be obtained from IRB (institutional review board). Confidentiality of the participants will be maintained, and informed written consent will be taken from the patient at the beginning of the study. The contents of the consent will be an explanation of the nature and purpose of the study, an explanation of the procedure of the study, and an explanation that they have the right to refuse or accept to participate in the study. The patient will not gain financial benefit from this study. Many researchers worked on the tool before but till to date we have not succeeded to find a comprehensive adaptation & validation of this important tool. It is expected that it will aid the researcher and clinician to understand the problem and make a potential solution in the future.
