The present study aims to fill that gap by testing the
efficacy of this training program in a randomized, controlled
trial (RCT) and comparing the intervention group (IG) with
wait-list controls (WLC). It was hypothesized that the paincontrol
training would significantly reduce pain symptoms
(frequency, duration, intensity, and pain-related impairment)
as well as increase health-related quality of life compared to
the wait-list controls, both directly post-treatment and at the
3-month follow-up post-treatment
