This study aimed to analyze the correlation between cognitive and emotional factors with chronic low back pain among women in Isfahan, Iran. Methods and Materials: In this cross-sectional research, the target population included all women with chronic low back pain that referred to clinics and hospitals of Isfahan during summer 2011. A total number of 50 women with chronic low back pain were selected by simple random sampling. Instruments used in this research included a demographic questionnaire, the multidimensional pain inventory, the fear-avoidance beliefs inventory, the pain catastrophizing scale, and the hospital anxiety scale. The obtained data was analyzed by stepwise and hierarchical regression analysis and Pearson's correlation coefficient. Findings: Pain was positively related with fear-avoidance beliefs, catastrophizing, and anxiety. The results of stepwise regression showed that fear-avoidance beliefs and catastrophizing explained 45.6% of the variance of the pain. In addition, moderated hierarchical regression analysis revealed that job had a moderating effect on the relationship between anxiety and pain. Conclusions: Chronic low back pain can be predicted by fear-avoidance beliefs and catastrophizing. Moreover, decreasing professional stress would reduce the overall anxiety and thus low back pain among women.
