Validation of the Arabic Version of the Short Form Leed's Dyspepsia Index (SF-LDQ) Amongst Patients with Type II Diabetes
Clinical epidemiology and global health(2021)
Abstract
Since an unambiguous clinical definition of dyspepsia does not currently exist, the diagnosis is made on the basis of symptoms. For this purpose, a tool which is valid, reliable and convenient to use is needed that can accurately assess both frequency and severity of dyspepsia. Short-Form Leeds Dyspepsia Questionnaire meets all of these requirements and thus, has to be validated in native languages before it can be used to diagnose dyspepsia. We conducted a cross-sectional study at King Abdullah Bin Abdulaziz University Hospital (KAAUH) in Riyadh, Saudi Arabia. Adult patients with type II diabetes were recruited in the study after giving informed consent. A total of 245 patients were recruited in the study; 95 (38.8%) were males, while 149 (61.1%) were females. We found that 27.3% (n = 67) of the participants had dyspepsia according to the SF-LDQ Arabic version compared to 24.1% (n = 59) by physician's diagnosis. The Area Under the Curve was 0.86 (95% CI: 0.81–0.9). At a cut-off value of 7/32, the tool has a sensitivity of 69.49% and a specificity of 83.24%. In conclusion, The Short-Form Leeds Dyspepsia Questionnaire was found to be valid for assessment of frequency and severity of dyspepsia among Arab diabetes Type 2 patients.
