Neuroticism and maladaptive coping in patients with functional somatic syndromes.

The results give support to a generic cognitive-behavioural model of FSS. Targeting symptom catastrophizing may be an essential component in CBT for patients with FSS, regardless of their specific diagnosis. Statement of contribution What is already known on this subject? Previous studies have found support for single components of the cognitive-behavioural model such as dysfunctional illness beliefs or avoidant coping. Most studies have investigated single functional somatic syndromes (FSS) such as fibromyalgia or irritable bowel syndrome. What does this study add? Predisposing neuroticism was linked to poor physical health through symptom catastrophizing across a range of FSS. Reduced symptom catastrophizing during group cognitive-behavioural therapy partially mediated its long-term effect. Addressing symptom catastrophizing may be a key element of the management of patients with FSS.
