  1. Change scores of all negative items are reversed. A positive change score indicates an improvement in HRQOL, a negative change score indicates a decline in HRQoL. A positive β of the positive items = more positive mood associated with an improvement in mood. A positive β of the negative items = decline negative mood/symptomology associated with an improvement in health/mood. All regression models were adjusted for baseline momentary (mean) and retrospective scores
  2. *P values < 0.05 were considered significant
