Background:Attitudes and beliefs about pain determine the interpersonal interaction in evaluation and treatment of a chronic painful condition like fibromyalgia in a multidisciplinary healthcare system. Two distinct dimensions for pain attitudes and beliefs were identified as Biomedical and Behavioral. The former utilized a pathoanatomical model whereas the latter incorporated the psychosocial factors into clinical presentations.Objectives:The study aimed to evaluate the pain attitudes and beliefs amongst rhematologists, physical therapists and fibromyalgia patients and to compare the biomedical and behavioral dimensions between the three groups in study population of fibromyalgia syndrome (FMS).Methods:A nation-wide cross-sectional survey (online and direct interviews) was conducted between 2010-16 to identify first group- 18 (16 male, 2 female) rheumatologists (snowball sampling), and second group- 122 (44 male, 78 female) physical therapists (purposive sampling), both with previous experience of treating adults with fibromyalgia. Also 188 patients with FMS were also studied from outpatient departments of tertiary care hospitals as the third group. All participants filled the Pain Attitudes and Beliefs (PABS) scale and the scores were analysed to identify the two dimensions descriptively in percentiles, and their between-group comparisons were done using Chi-Square test at 95% confidence interval using SPSS version 22 for Windows software.Results:There was an overall predominance of biomedical dimension for FMS reported in all three groups, with rheumatologists being most prevalent (76.8%), followed by patients (65.6%) and then by physical therapists (54.12)%. Between-group comparisons were significant (p<.05) for all 6 analyses.Conclusion:Biomedical dimension was predominantly reported by rhematologists, physical therapists and patients for chronic pain in FMS and this necessitates further research on development and implementation of educational interventions in this part of the world.References:[1]Kumar SP, Jim A.
