Table 6.

Responsiveness indices: declined and unchanged groups based on “On a scale of 1 to 10, where 10 is best possible quality of life and 1 is the worst possible quality of life (as bad or worse than being dead) overall, how would you rate your quality of life?”a

aDeclined group declined two or more categories from baseline to follow-up (n = 16); Unchanged group had change of one point or less from baseline to follow-up (n = 35). All the scales scored on a 0 (worst) to 100 (best) possible range, except for the SF-36 PCS and MCS, which are T-scores (mean = 50, SD = 10) calculated against a reference population

bLarge effect size (effect size between 0.20 and 0.49)

cMedium effect size (effect size between 0.50 and 0.79)

dSmall effect size (effect size greater than or equal to 0.80)
