Shortening of the CES-D to improve its ability to detect cases of depression

Article Abstract:

The Center of Epidemiologic Studies-Depression Scale (CES-D) is commonly used to identify depressed individuals. Primary care patients with and without major depressive disorders endorsed individual response options on the CES-D, and the results were used to identify a subset of items, which improved the effeciency with which depressed individuals were identified. The CES-D could be more efficient with improved analytic techniques, but it is still limited as a self-report screening measure.

Progress in the technology of measurement: applications of item response models

Article Abstract:

A study was conducted to analyze the fundamentals of item response models and their applications. Differences between nonparametric item response models and parametric response frameworks were examined. Issues correlated with the realization of a fair and equitable assessment of traits, abilities, or conditions were also determined. In addition, examples of option characteristic curves modeled with a parametric logistic model were characterized.
