ABSTRACT
OBJECTIVE:
To determine the Physical Component Summary (PCS) score's minimal clinically important difference (MCID) on the Short Form 36 (SF-36) for people with stroke.METHODS:
We conducted secondary analysis of data from a large randomized controlled trial (N = 400) in the post-hospital discharge phase of stroke rehabilitation with outcome measurement 6 and 12 months following stroke. Three methods were used for estimating the MCID two anchor and one distribution. Method 1 compared SF-36 PCS scores at 12 months for responses to the SF-36's Perceived Health Change (PHC) question. Method 2 compared the change in PCS score between 6 and 12 months for responses to the PHC question. Method 3 used Cohen's method to estimate the MCID from the PCS score distribution.RESULTS:
Method 1 the mean PCS score increased by 3.0 units (95% confidence interval [CI] 2.2-3.9) for each unit change in the PHC question. Method 2 the mean change in PCS score increased by 2.1 units (95% CI 1.4-2.8) for each unit change in the PHC question. Method 3 the MCID was estimated to be 1.8 units.CONCLUSIONS:
Our estimate of the MCID for the PCS in patients with stroke was 1.8 to 3.0 units.Palabras clave
