The effects of acceptance- and mindfulness- based interventions on chronic pain: A systematic review

Acceptanceand mindfulnessbased interventions as MindfulnessBased Stress Reduction program (MBSR), MindfulnessBased Cognitive Therapy (MBCT) and Acceptance and Commitment Therapy (ACT) are new generation of CognitiveBehavioral Therapies for the treatment of chronic pain. To evaluate the effectiveness of acceptanceand mindfulnessbased interventions on patients with chronic pain, a systematic review was conducted. Outcome measures were pain intensity, physical wellbeing and quality of life. Twentyfour randomized controlled trials were included, totaling 1521 patients with chronic pain. Based on the results, it can be concluded that acceptanceand mindfulnessbased interventions may have a positive effect on pain intensity, physical wellbeing and quality of life in patients with chronic pain. Additionally, mindfulnessbased interventions may have a superior effect than acceptancebased interventions on pain intensity. This review found limited evidence for the effectiveness of acceptancebased interventions on physical wellbeing and quality of life. A following metaanalysis and more highquality studies are recommended to produce more differentiated and validated findings.
