Catastrophizing, Acceptance, and Coping as Mediators Between Pain and Emotional Distress and Disability in Fibromyalgia

Abstract

Catastrophizing, acceptance, and coping have an important predictive value in chronic pain; however, it is not known which of these variables has the greatest contribution in fibromyalgia (FM). This study explored the mediating role of catastrophizing, acceptance, and coping in the relationship between pain and emotional distress/disability in a FM sample. Ninety-two FM patients and 51 healthy participants controls were evaluated on pain- and psychological-related variables. Catastrophizing, acceptance, behavioral coping, and emotional coping were significantly correlated with emotional distress and/or disability. Catastrophizing had a significant effect as a mediator on the relationship between pain and depression/anxiety. The current management of FM could improve by including cognitive techniques aimed at modifying the negative appraisal of pain.
