The purpose of present study was to evaluate the structural pattern of the relationships between the pain vulnerability, catastrophizing, fear of pain and pain adjustment (pain intensity and inability) in the framework fear-avoidance model.Methods: Patients with chronic musculoskeletal pain were selected from hospitals and private clinics in Isfahan city, Iran, during 2015 using convenience sampling method. They participated in the research by filling out six questionnaires: NEO Five-Factor Inventory (NEO-FFI), Positive and Negative Affect Schedule (PANAS), Acceptance and Action Questionnaire (AAQ), Pain Catastrophizing Scale (PCS), Tampa Scale Kinesiophobia (TSK) and Graded Chronic Pain Scale (GCP). Data were analyzed using structural equation modeling method.Findings: Pain vulnerability had significant direct effects on catastrophizing and catastrophizing on fear of pain and fear of pain on pain adjustment (P < 0.001 for all). In addition, catastrophizing through pain vulnerability and fear of paintrough catastrophizing had indirect effects on pain adjustment; while the direct relationship between vulnerability and pain adjustment was not confirmed.Conclusion: The results of this research showed that pain vulnerability could predict pain adjustment in the framework fear-avoidance model. Therefore, reducing pain vulnerability can reduce pain intensity and inability in patients with chronic musculoskeletal pain.
