| Annotation | The Center for Epidemiologic Studies Depression Scale (CES-D) is frequently used in studies of older people. One controversy regarding its use turns on the issue of whether the effect of physical disorder on the CES-D total score reflects genuine effects on depression or item-level effects. The authors examine this issue, using medical examination data from 506 Australian over 75s living in the community, and who were part of the Sydney Older Persons' Study. A form of structural equation modelling, the Multiple Indicators, Multiple Causes (MIMIC) model, is used, enabling the effect of a physical disorder on CES-D total score to be partitioned into bias and genuine depression components. The results show substantial physical disorder-related artefacts with the CES-D total score. Caution is required in the use of CES-D (and possibly other) depression scales in groups, such as older people, in which physical disorders are present. (RH). |
