  1. Minimum and maximum scores, median, mean and standard deviations and identical responses on test and retest in percent (IR) of total and domain score for OSS, SPADI and WORC. Reliability statistics estimated by ICC with 95% CI and Cronbachs alpha.
  2. Descriptive data from the first administration of the questionnaires. Retest data is not reported. WORC domain scores presented from 0 (worst possible) to 100 (best possible). The percentage of respondents with maximum score in WORC lifestyle domain is given in parenthesis. 95% CI = 95% confidence interval. SD = standard deviation
