OBJECTIVES: Psychosocial and environmental factors might have a potential causal relationship with chronic pain and the related disability. Psychosocial and environmental factors, socioeconomic status (SES) mediate the relationship among pain, disability, and can cause the morbidity and mortality among various conditions. Factor analyses of the Pain catastrophizing Scale (PCS) have shown that catastrophizing can be viewed as a multidimensional construct comprising elements of rumination, magnification and helplessness. The purpose of this study was to investigate the correlation between catastrophizing and the level of pain intensity, disability, in patients with chronic low back pain (CLBP). METHODS: An observational study was conducted. Participants were recruited from pain clinic of a public tertiary care hospital. Patients of either gender, aged 18–75 years with CLBP for ≥ 3 months, were eligible for study. Data regarding pain intensity, disability using MODQ (Modified Oswestry Disability Questionnaire), coping behaviour using PCS, socioeconomic status using Kuppuswamy scale, demographic and disease details were collected. Multiple correlation analysis was performed among the clinical variables with level of significance of 0.05.  RESULTS: A total of 74 patients were included in the study. Mean age and duration of low back pain was 46±14 yrs and 36±32 months respectively. The mean helplessness, magnification and rumination were found 11.7±3, 5.5±2 and 7.3±2 respectively. We found a signification positive correlation between total PCS and pain intensity (r = 0.66, P =0.001), disability (r = 0.67, P = 0.001). Socioeconomic status (r = 0.15, P = 0.09) and duration of low back pain (r = 0.06, P = 0.3) was not significantly correlated with total PCS score. A similar trend was seen among the subscales of PCS. CONCLUSIONS: Coping behaviours in patients was significantly negatively associated with pain intensity and disability. Treatment aimed at reducing pain intensity and disability can improve patients coping behaviour.
