1. Develop computer code to administer the Center for Epidemiologic Studies Depression Scale (CES-D scale) using a handheld device.
2. Explore mode effects that might be present when monitoring depression symptomology with the CES-D using a handheld device.
3. Collect additional items measuring depressive symptomology to be used for development of a CAT measuring depression symptomology to be administered using the handheld device that would not depend on mode effects. |
