RESUMO
OBJECTIVES: This study was proposed to evaluate the reliability by 2005 Sasangin Diagnosis Questionnaire for Mongolian (05' SDQ-M). DESIGN: Questions from the 05'SDQ were translated into Mongolian, and the 05'SDQ-M was constructed. The questionnaire was administered to 193 Mongolians and they were asked to complete the questionnaire again 2 weeks after the first administration. To evaluate the internal consistency, Cronbach's alpha coefficient was calculated. A reliability analysis for each individual question was conducted using the test-retest method to verify the independence and agreement between the questions. To verify independence, a chi(2) test with crosstabs analysis and p-values was used. The agreement verification was conducted by using the Cohen kappa coefficient. In addition, the constitutional variable was defined as the constitutional attribute of each question, and Pearson's correlation coefficient was confirmed after testing the scale. RESULTS AND CONCLUSIONS: After testing the internal consistency of the scale, the consistency was shown to range from 0.59 to 0.67, suggesting that the questions on the questionnaire were reliable. The test-retest method showed that Pearson's correlation coefficients for the results of the two tests ranged from 0.65 to 0.80. The x(2) test results indicated that one independent item demanded close attention. Among the other 123 questions, the agreement test revealed that 80 questions (64.5%) showed common agreement.
