| الوصف: | Fibromyalgia is a chronic pain condition associated with substantial suffering and societal costs. Traditional cognitive behavior therapy (T-CBT) is the most evaluated psychological treatment, but exposure therapy (Exp-CBT) has shown promise with a pronounced focus on the reduction of pain-related avoidance behaviors. In a recent randomized controlled trial (N = 274), we found that Exp-CBT was not superior to T-CBT (d = −0.10) in reducing overall fibromyalgia severity. This study investigated pain-related avoidance behaviors, pain catastrophizing, hypervigilance, pacing, overdoing and physical activity as potential mediators of the treatment effect. Mediation analyses were based on parallel process growth models fitted on 11 weekly measurement points, and week-by-week time-lagged effects were tested using random intercepts cross-lagged panel models. Results indicated that a reduction in avoidance behaviors, pain catastrophizing, and hypervigilance were significant mediators of change in both treatments. An increase in pacing and a reduction in overdoing were significant mediators in T-CBT only. Physical activity was not a mediator. In the time-lagged analyses, an unequivocal effect on subsequent fibromyalgia severity was seen of avoidance and catastrophizing in Exp-CBT, and of overdoing in T-CBT. Exposure-based and traditional CBT for fibromyalgia appear to share common treatment mediators, namely pain-related avoidance behavior, catastrophizing and hypervigilance. |
