The multiple-factor analysis for anxiety, depression and acceptance of illness showed acceptance of illness to be a significant independent determinant of higher quality of life in the PCS (β = 1.580; p < 0.000) and MCS (β = 1.980; p < 0.000) domains.
Outcomes included mental and physical component summary scores (MCS and PCS) calculated from the Short Form (SF)-36v2 or SF-12v2, SF-6D health utility scores, self-reported psychological complaints (anxiety, depression and sleep difficulties), work productivity and activity impairment, and self-reported healthcare resource utilization.
