An additional group of 52 questionnaires tested for false negatives among those patients whose records did not meet the case definition but who did have a record of diabetes and treated neuropathy; for example when a diabetic patient had peripheral neuropathy but was already on prescription treatment for an analgesic at the time of the first mention of peripheral neuropathy.

Our analyses of associations revealed two groups of correlated questionnaire items, and based on those, we created two indices that we designated the knowledge index and the skills index.
The final 13-item pool was then validated using data from a cohort of patients with moderate severe COPD (N = 547) enrolled in a randomized clinical trial (RCT), to demonstrate the internal consistency, reliability, and validity (convergent and known-groups) of the questionnaire [ 8].
