Clinically meaningful reductions in pain severity are indicated by a 30% reduction or more.
Clinically meaningful differences are indicated by a 9.5-point reduction or more.
A clinically meaningful cut-off score for the Pain Catastrophizing Scale is 20.
A cut-off score of 10 and above indicates major depressive disorder.
Indicates that this score (in bold) satisfies criteria for cut-score/clinically meaningful change at follow-up.
n/a = participant did not complete the questionnaire. Note: Participant 11 did not complete the postprogram or follow-up questionnaires due to early program drop-out but did participate in the interview.
