Title: Psychological pain treatment in fibromyalgia syndrome: efficacy of operant behavioural and cognitive behavioural treatments
Author: Thieme, Kati; Flor, Herta; Turk, Dennis C.
Abstract: The present study focused on the evaluation of the effects of operant behavioural (OBT) and cognitive behavioural (CBT) treatments for fibromyalgia syndrome (FMS). One hundred and twenty-five patients who fulfilled the American College of Rheumatology criteria for FMS were randomly assigned to OBT (n = 43), CBT (n = 42), or an attention-placebo (AP) treatment (n = 40) that consisted of discussions of FMS-related problems. Assessments of physical functioning, pain, affective distress, and cognitive and behavioural variables were performed pretreatment and post-treatment as well as 6 and 12 months posttreatment. Patients receiving the OBT or CBT reported a significant reduction in pain intensity post-treatment (all Fs > 3.89, all Ps less than 0.01). In addition, the CBT group reported statistically significant improvements in cognitive (all Fs > 7.95, all P less than 0.01) and affective variables (all Fs graeater than 2.99, all Ps less than 0.02), and the OBT group demonstrated statistically significant improvements in physical functioning and behavioural variables (all Fs greater than 5.99, all Ps less than 0.001) compared with AP. The AP group reported no significant improvement but actually deterioration in the outcome variables. The post-treatment effects for the OBT and CBT groups were maintained at both the 6- and 12-month follow-ups. These results suggest that both OBT and CBT are effective in treating patients with FMS with some differences in the outcome measures specifically targeted by the individual treatments compared with an unstructured discussion group. The AP group showed that unstructured discussion of FMSrelated problems may be detrimental.
