Figure 1From: Variability in depression prevalence in early rheumatoid arthritis: a comparison of the CES-D and HAD-D Scales Item map showing location values for the combined items of the CES-D13 and HADS-D. The item map shows the relative positioning of the items in terms of their difficulty. CES-D item 19 is the most difficult item to endorse and therefore indicative of the severe end of the levels of depression, whereas HADS-D item 8 is the least difficult item to endorse and therefore indicative of the lowest of depression levels.Back to article page
