Tobin, J. (2014). Effect of mindfulness-based interventions on symptoms of fibromyalgia: A meta-analysis (Doctoral dissertation, California State University, Fullerton).
From the Abstract. Mindfulness provides an alternative or supplement to traditional pharmacological treatment of fibromyalgia, but it is not yet clear how effective it is in reducing symptoms. The purpose of this meta-analysis was to explore the efficacy of mindfulness-based interventions on fibromyalgia impact, pain severity, and psychological distress in adults diagnosed with fibromyalgia. A total of 11 randomized controlled trials were included in the analysis, all of which measured at least one of the designated outcomes.
Studies’ data was pooled and standardized mean differences were calculated. Results showed a moderate to large intervention effect for each outcome. Subgroup analyses were conducted for each outcome based on control group type (active versus wait list), and for each outcome, all subgroups’ SMD significantly favored the experimental condition, with the exception of the active controls for psychological distress.
… While this analysis yielded results suggesting the efficacy of mindfulness in reducing symptoms of fibromyalgia, future meta-analyses may consider including studies of more diverse methodological quality to create more robust and powerful effect sizes, while exploring methodology as a potential moderator.
