Responsiveness of psychological scales
| Scale | PPMS (n = 104) | Rehabilitation (n = 64) | Steroids (n = 77) | χ2* (DR)† |
|---|---|---|---|---|
| *χ2 values from Kruskal Wallis ANOVA; †DR (differential responsiveness) = pairwise χ2 values (for example, for SF-36MH = 100×22.4/56.9); ‡ES, effect size; SRM, standardised response mean; §z values from Wilcoxon’s signed ranks test; ¶RE (relative efficiency) = pairwise square z values (for example, for SF-36MH in rehabilitation = 100×(−3.441)2/(−4.954)2). | ||||
