The present literature indicates that chronic pain patients who report higher levels of anger, reported poor adjustment to pain adjustment. In this study, 149 chronic pain patients completed the following measures: mood, physical disability, anger, pain intensity, pain-related interference with daily activities and physical and mental components of quality of life. In addition, all patients were required to answer the following question: "Who (or what) do you think is responsible for the onset of your pain? Anger was prevalent among the study sample; Patients who scored higher in anger were more depressed and scored lower in the mental components of quality of life. In the present study, patients were classified according to their response to the question: "Who (or what) do you think is responsible for the onset of your pain?" The resulting three groups did not differ in pain intensity and mental and physical components of quality of life. However, patients who held the belief that their pain resulted from the intent or negligence of someone else (Group3) scored higher on depression and anger, compared to the patients in groups 1 and 2. Furthermore, patients in group 3 scored higher on physical disability and pain-related interference in daily activities, relative to patients in group 2. The patients in Groups 1 and 2 were not statistically different in any of the study variables.
