↵* Unless indicated otherwise.
↵† Test-retest interval was 5–6 mo (June–December 2000). N/C = not computed since response categories were different in June and December.
↵‡ General practitioners
↵§ Items were worded slightly differently in the June and December versions.
↵¶ For the test-retest analysis, responses for the June version were coded into 3 levels.
VAS = visual analogue scale.
