Table 2.
Meaningful change estimates for the Mini-BESTest based on patient and physiotherapist ratings using the global rating scale and distribution-based methods (n = 50).
Mini-BESTest component | Global rating of change scale collapsed, mean (SD) | SEM | MDC95 | MCID small change* | MCID substantial change* | ||

Anticipatory patient | 0.7 (0.8) | 0.4 (0.7) | 0.9 (0.9) | 0.4 | 1.0 | 1 | 1 |

SEM: minimal clinically important difference; MDC: minimal detectable change; MCID: minimal clinically important difference.
Global Rating Change scale collapsed: about the same (a little better/not meaningful and about the same); a little better/meaningful and much better.
The minimal clinically important difference value for small change was selected as the larger of either the anchor-based estimate for small change (about the same and a little better) or the distribution-based standard error of measurement, rounded to the nearest whole number. The minimal clinically important difference value for substantial change was selected as the larger of either the anchor-based estimate for substantial change (much better) or the distribution-based MDC95, rounded to the nearest whole number.
