Introduction: In 2017, the American Diabetes Association (ADA) have introduced and recommended a Diabetes Risk Test for immediate detection of diabetes mellitus. Given the growing number of diabetics worldwide and in our country, early diagnosis and control of diabetes is vital. This study aimed to validate the modified filipino version of the ADA Diabetes Risk Test and the SLIM (St. Luke’s Internal Medicine) Diabetes Risk Test.

Methods: Phase I of this study involved questionnaire formulation, forward-back-forward translation, pilot testing and cognitive debriefing, and initial validation process (content validity, face validity, and test-retest reliability). There were 30 participants in the pilot testing, six experts for content validity, 40 patients in face validity, and 30 subjects for the test-retest reliability.

Results: The modified filipino version of the ADA Diabetes Risk Test and the SLIM Diabetes Risk Test formulated were considered relevant by majority of the subjects from the pilot testing and face validity and had content validity score from experts ranging from 80-100%. Items 1-4, and 8 of the questionnaires showed a kappa of one (p-value of <0.001) while the rest of the questions had kappa scores ranging from 0.60 to 0.86.

Conclusion: The St. Luke’s Internal Medicine (SLIM) Diabetes Risk Test, a 12-item questionnaire, was developed from the modified Filipino version of the ADA Diabetes Risk test incorporating other risk factors for diabetes to cater for adult Filipino patients. Phase I of this study showed that this questionnaire has acceptable content validity with moderate to perfect test-retesting reliability. Phase II of this study testing the criterion validity to determine diagnostic accuracy is ongoing.
