Table 1.

Distribution-based estimates of the minimal important difference (MID) and results.

Method MID calculation MID (min) MID (s)
SEM SDbaseline * sqrt (1 − ICC) −0.38 22.8
Empirical rule effect size 0.08 * 6 * SDΔ −0.41 24.6
Cohen's effect size 0.5 * SDΔ −0.43 25.8
0.5 times SD 0.5 * SDbaseline −0.84 50.4
MDC 1.96 * sqrt (2) * SEM −1.05 63.2

MID, minimal important difference; SEM, standard error of measurement; SD, standard deviation; sqrt, square root; ICC, intraclass correlation coeficiente; Δ, difference in Glittre ADL-test (end − baseline rehabilitation); baseline, time in Glittre ADL-test at baseline; MDC, minimal detectable change.
