Abstract

To validate SODA (severity of dyspepsia assessment) questionnaire in our population for evaluating symptoms severity in patients with dyspepsia. Content and appearance validity were measured, and then a modified questionnaire was developed. A pilot test was made and reliability, construct validity and responsiveness were measured. An adequate content and appearance validity were obtained. On the pilot test, reliability of the complete questionnaire and by components had Cronbach alpha values over 0,7. Construct validity of SODA was evaluated by correlating modified SODA results with SF-36 scores using Pearson test: -0.72 (p<0.001). When we compared results of modified SODA questionnaire and the score of a question about subjective perception of the disease using Spearman test we obtained similar results: 0.72 (p<0.001). Two means of SODA questionnaire scores, before and after treatment, were compared using Student's T test, and a significant difference was found, (p<0.001) with a drop mean of 5.70 ±5.33. Modified SODA questionnaire meets all criteria of validity and it could be used to measure dyspepsia severity and its evolution in a Peruvian population.
