3 Sensitivity and Specificity

4 Sensitivity by Age

5 Specificity by Age

10 Spearman Rank Correlation

13 Correspondence Analysis between W6 and D1.5 (cont.)

14 Correspondence Analysis between W6 and D1.6

15 Correspondence Analysis between W6 and D1.6 (cont.)

16 Results Summary In general, WG Q showed good specificity but very low sensitivity (28.4%) WHO DAS II questions on communication were more sensitive WG Q indicated higher sensitivity and lower specificity among older age groups

17 Results Summary (cont.) Fiji, followed by Indonesia, had significantly lower sensitivity scores W6 is significantly and moderately correlated with D1.5 and D1.6 D1.5 and D1.6 are significantly and highly correlated with each other W6 question, possibly due to the complicated phrasing, caused some cognitive problems
