Sickness impact profile: a measure of dysfunction with chronic pain patients

Although chronic pain may affect all facets of a patient's life, there is no generally accepted method of measuring the extent of the disability experienced. This component of a larger study examined changes in usual activities and relationships for patients experiencing chronic nonmalignant pain, in order to understand the impact of pain on an individual's life. The effect of pain intensity and depression on the performance of usual daily activities was assessed by the Sickness Impact Profile (SIP). The sample of 34 subjects, 17 women and 17 men, rated their pain as moderate to severe on a linear analogue scale (mean 64). Thirty percent of subjects were moderately to severely depressed as measured by the Beck Depression Inventory (mean 21). The SIP scores indicated severe disruption in daily activities and relationships for this sample. Significant correlations between the SIP and visual analogue scales measuring coping adequacy and activity levels were interesting and warrant further study.
