Quality-of-life assessment in a home care program for advanced cancer patients: a study using the Symptom Distress Scale.

Abstract

Quality-of-life assessment in advanced cancer patients should include the study of physical function, psychological status, social interactions, and symptoms. "Symptom distress" relates to the degree of discomfort caused by specific symptoms. A Symptom Distress Scale, which has been developed by McCorkle and Young, is a self-rating instrument that evaluates 13 symptoms. In the present study, the Italian version of the Symptom Distress Scale (SDS) was used to assess the quality of life in advanced cancer patients. The internal consistency of this version was found to be good (Cronbach's coefficient alpha = 0.78). A sample group of 43 patients treated in a home care program was asked to fill out the SDS on a weekly basis. The scores showed a reduction in symptom distress, which was primarily due to improvement in pain, nausea, and bowel pattern. Home care was less effective in improving concentration and, more generally, psychological aspects. This study confirms the validity of a quality-of-life monitoring system that uses a patient self-rating symptom assessment instrument.
