Validation of the Arabic version of the Short Form Leed's Dyspepsia Index (SF-LDQ) amongst patients with type II diabetes

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.
