This study was conducted to assess quality of life in patients suffering from different density of chronic low back pain. The sample consisted of 101 patients with chronic low back pain attending to the Rheumatology Research Center of Tehran University of Medical Sciences between July and September 2003. All patients were female, married, aged 18 years or over and underwent rheumatologic clinical examination. Data were collected by face-to-face interviews using the Iranian version of the Short Form Health Survey (SF-36). Relative to mean score of bodily pain, patients were divided into 2 groups: severe pain group (group 1) and mild pain group (group 2). Then, quality of life scores was compared between these two groups.
