How durable are the effects of cognitive-behavioural therapy‎ in controlling fibromyalgia symptoms? A prospective cohort study 2023 Zabihiyeganeh

Purpose

Cognitive-behavioural therapy (CBT) is widely used for the treatment of fibromyalgia. However, there is no consensus on the durability of its effects on these patients. In this study, we evaluated how durable are the effects of CBT in controlling fibromyalgia symptoms.

Methods
Forty-eight fibromyalgia patients treated with traditional face-to-face CBT were included. CBT was performed in 20 consecutive group sessions. To evaluate the durability of treatment, the effects of CBT on fibromyalgia symptoms were checked at five time-points: before the CBT, immediately after the CBT, 3 months after the CBT, 6 months after the CBT, and 12 months after the CBT. Outcome measures were the Fibromyalgia impact questionnaire (FIQ) and widespread pain index (WPI).

Results
The mean FIQ score of the patients was 68.3 ± 18.8 before the CBT and 50.5 ± 14.1 1 week after the CBT (p < 0.001). The mean post-CBT FIQ score did not significantly change three and 6 months after the CBT (p = 0.11 and p = 0.09, respectively) while the positive effects of CBT significantly diminished after 12 months (p < 0.001). The mean WPI was 10.4 ± 3.6 before the CBT and 8.6 ± 3.1 1 week after the end of CBT (p < 0.001). The mean WPI of three and 6 months was not statistically different from that immediately after the CBT (p = 0.18 and p = 0.15, respectively), while after 12 months, it significantly worsened (p < 0.001).

Conclusion
CBT's beneficial effects for fibromyalgia patients are durable for 6 months. Complementary CBT sessions could be implemented to boost the CBT effect after this period.
