There are scales that measure INDEPENDENCE, not "dependence."  From these measurements, we determine if the older adult is able to live in the community or does that person require assistance?  ADL, IADL, Frailty Wheel, GDS-SF, Nestle Nutritional Assessment, and add a cognitive assesment such as SLUMS or GP-COG Modified.  Also, if the individual drives, a driving assessment is in order [with simulator].  These assessments must be conducted by an experienced and qualified geriatrician [not a novice or student].  They are available from PAR.  If they approve you to buy them, you can administer them.  Don't be tempted by using bootleg copies, as it could really get you into trouble.  Jan Vinita White, PhD Gerontologist
