Metacognitions on Pain, Functionality and Intensity of Pain in Women with Fibromyalgia

To determine the explanatory capacity of pain metacognitions and beliefs over the functionality, coping and pain intensity, following the Model of Self-Regulatory Executive Functions (S-REF) in a sample of women with fibromyalgia from Medellín and its Metropolitan Area. Method: Metacognitions Scale on Symptom Control, Pain Self-efficacy Questionnaire, Chronic Pain Catastrophizing Scale, Chronic Pain Coping Questionnaire, WHODAS 2.0 Scale, and Pain Intensity Numerical Scale. The sample was represented by 108 women between 24 and 60 years old with a diagnosis of fibromyalgia. A modeling process was carried out through an analysis of structural equations. Results: The final model fails to fit. Despite this, the analysis suggests that negative metacognitions and pain self-efficacy have an effect over the tendency to catastrophizing. The latter and the pain self-efficacy are the main mediators in the effects of functionality. The intensity of pain is not determined by the metacognitions related to it.
