The sensitivity index was calculated as the ratio between the mean change in scores from t1 to t2 and the standard deviation of the baseline mean scores. Values > 0.2 = modest sensitivity; > 0.5 = moderate sensitivity; > 0.8 = good sensitivity.
↵2-150 p = 0.05.
↵2-151 The ceiling effect for each subscale is shown by the % and number of subjects with a maximum score at baseline.
