Higher scores indicate better QoL for all QLQ–C30 measures except fatigue; more benefit finding; and better CSE. Lower scores indicate less QLQ–C30 fatigue, less distress on K10 and more functional illness perceptions. dInt−Wait = effect size for Intervention improvement corrected for Waitlist improvement. Effect sizes associated with statistically significant interactions for RCT participants (p < 0.05) are shown in bold text; effect sizes associated with interaction trends (p < 0.10) are underlined.
