Frequency of depression among oncology outpatients and association with other symptoms

Abstract
Depression occurs among an estimated 15% of cancer patients (range, 1–77.5%). Our main objective was to identify the frequency of reported depression by using the Brief Edinburgh Depression Scale (BEDS) among cancer outpatients. Our secondary objective was to identify associated symptoms of cancer using the Edmonton Symptom Assessment System (ESAS) and to evaluate the screening performance of depression between ESAS and BEDS.
