Abstract

-Objectives: Previous research on the Fear-Avoidance Model (FAM) of chronic pain suggested the personality traits neuroticism and negative affect (NA) influenced pain catastrophizing. However, their corroborating influence on pain catastrophizing remains unclear. This study examined four possible models of relationships between neuroticism and NA in pain catastrophizing within the FAM framework using structural equation modeling. -Methods: A total of 401 patients with chronic musculoskeletal pain completed measures of neuroticism, NA, three core FAM components (pain catastrophizing, pain-related fear, and pain anxiety), and adjustment outcomes (pain-related disability and depression). -Results: Regression analyses refuted the possibility that neuroticism and NA moderated each other's effect on pain catastrophic thoughts (p>0.05). Results of SEM evidenced superior data-model fit for the collapse models in which neuroticism and NA were two secondary traits underlying a latent construct, negative emotion (Disability: CFI=0.93; Depression: CFI=0.91). –Conclusion: The results offer preliminary evidence that patients presented with more neurotic symptom and heightened NA probably elicit more catastrophic thoughts about pain.
