Differential efficacy between cognitive-behavioral therapy and mindfulness-based therapies for chronic pain: Systematic review.

Background/Objective: To assess the differential efficacy between mindfulness-based interventions and cognitive-behavioral Therapy (CBT) on chronic pain across medical conditions involving pain. Method: ProQuest, Science Direct, Google Scholar, Pubmed, and Embase databases were searched to identify randomized clinical trials. Measurements of mindfulness, pain, mood, and further miscellaneous measurements were included. Results: 18 studies met the inclusion criteria (fibromyalgia, n = 5; low back pain, n = 5; headache/migraine, n = 4; non-specific chronic pain, n = 4). In fibromyalgia, mindfulness based stress reduction (MBSR) was superior to the usual care and Fibroqol, in impact and symptoms. In low back pain, MBSR was superior to the usual care, but not to CBT, in physical functionality and pain intensity. There were no studies on differential efficacy between mindfulness and CBT for headache and non-specific chronic pain, but Mindfulness interventions were superior to the usual care in these syndromes. Conclusions: Mindfulness interventions are superior to usual cares in all diagnoses, but it is not possible to conclude their superiority over CBT. Comparisons between mindfulness interventions are scarce, with MBSR being the most studied. In central sensitization syndromes, variables associated with pain tend to improve with treatment. More research is needed to differentiate diagnosis and intervention.
