Overall quality of life, the main study outcome measure, showed a decline between baseline ( M = 5.29, SD = 1.29) and M3 ( M = 5.14, SD = 1.32) ( t (583) = 3.71; p < 0.001) and then increased back to levels comparable to those at baseline (M6: M = 5.48, SD = 1.16; M9: M = 5.48, SD = 1.19; M12: M = 5.52, SD = 1.23), with all changes relative to M3 being significant at p < 0.001 and changes from M0 being non-significant ( p = 0.14 and p = 0.17 for M6 and M9, respectively) or marginally significant ( p = 0.033 for M12).
