Cognitive-affective assets and vulnerabilities: two factors influencing adaptation to fibromyalgia

This study set to explore whether variables related to cognitive-affective assets would complement measures of psychological vulnerability for the prediction of physical functioning and pain tolerance in 138 women with Fibromyalgia Syndrome (FMS). Depression, anxiety, stress response and negative affect were defined a priori as measures of vulnerability, while pain self-efficacy, internality and positive affect were identified as assets. Confirmatory factor analyses supported the validity of the hypothesised two-factor structure in FMS. A structural equation model (SEM) revealed that the two factors were associated with different outcomes in FMS as predictors. Pain and associated symptoms appeared related to psychological vulnerabilities in FMS patients, whereas physical functioning and tolerance for pain were better predicted by assets. These results are discussed with reference to current theoretical models concerning the role of psychological factors in FMS, and intervention methods designed to improve quality of life and reduce pain in FMS patients.
