Abstract
Anxiety about pain is increasingly recognized as one factor contributing to increased pain perception and pain behavior [McCracken, L. M., Faber S. D., & Janeck A. S. (1998) Pain-related anxiety predicts nonspecific physical complaints in persons with chronic pain. Behavior Research and Therapy, 36, 621–630; McCracken L., & Gross R. (1995). The pain anxiety symptoms scale (PASS) and the assessment of emotional responses to pain. Innovations in clinical practice: a source book, 14, 309–321]. To assess this emotional reaction to pain in chronic pain patients, McCracken, Zayfert and Gross [McCracken, L., Zayfert, C., & Gross, R. (1992). The Pain Anxiety Sympton Scale: development and validation of a scale to measure fear of pain. Pain, 50, 67–73] developed the Pain Anxiety Symptom Scale (PASS) composed of four subscales: Cognitive Anxiety, Fearful Appraisal, Escape Avoidance and Physiological Anxiety. The present study extended previous work by examining the relationship among pain anxiety dimensions, use of active and passive coping strategies and arthritis self-efficacy as predictors of functional status in 154 rheumatoid arthritis (RA) patients. Functional status was assessed using the Five-Factor Model of the Arthritis Impact Scale, 2nd ed., (AIMS2): Physical Functioning, Affective Experience, Symptoms, Social Interaction and Role Function. Hierarchical multiple regression analysis on each of the AIMS2 criterion variables showed that pain anxiety, pain and symptom self-efficacy, health status and coping strategies were able to explain between 9 and 38% of the variance in the five AIMS2 variables. The present results support the hypothesized role of pain anxiety along with previously established contributions of self-efficacy and coping strategies, in affecting physical, social, emotional and role functioning in chronic RA patients.
