  1. * High values represent a bad level for the items 'physical strain in work' and 'resigning coping'.
  2. A high value is good for all other items.
  3. Data are given as medians (min-max) and as differences within groups.
  4. p 1 = differences between the groups at baseline (Mann Whitney U)
  5. p 2 = baseline compared with 10-week follow-up within the groups (Wilcoxon Signed Ranks Test)
  6. p 3 = baseline compared with 9 month follow-up within the groups (Wilcoxon Signed Ranks Test)
