Start Date: Jan 09 2008
End Date: OPEN
Establish the feasibility of the three in-house assessments methods—Mail in forms with live phone, automated telephone IVR technology and computer-based kiosk assessment and validate them by comparing them to traditional evaluation instruments.

To examine medication adherence as a performance based assessment of functional ability in all 3 methods.
