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

Article Abstract:

Research was conducted to examine the unresolved issues regarding the assessment of depression. Such issues include the ability of existing measures to detect differences in depressive severity, the relative effectiveness of response options and the extent to which certain groups use options and items differently. Results indicate that analytic techniques based on item response models do not only efficiently identify and resolve such issues but that they are also important in ensuring that abilities, conditions and traits are evaluated equitably and fairly.

The growing population of the elderly in the U.S. and other countries has resulted in an expansion of geriatric research and a need for for new methodologies.
