Self-Report Depression Scales in the Elderly: The Relationship between the CES-D and ZUNG

Abstract

Depression is one of the most common mental health problems in the elderly, but there is little consensus about the best way to assess depression in the aged. The relationship between the CES-D and the ZUNG self-report depression scales was investigated in seventy-eight elderly people with osteoarthritis (mean age 71). The correlation between the scales was r = .69, with the CES-D classifying 15 percent of the participants as depressed, as compared to 6 percent by the ZUNG. Psychological symptoms had the strongest relationship with overall depression scores on both scales. No sex differences were found on psychological items on either scale, but females reported more somatic symptoms on the ZUNG. People over age seventy-four reported more psychological symptoms than their younger counterparts.
