Outcome & change assessment - gereatric patients attending a day hospital

I'm looking for measures of change in mood and functioning of gereatric patients attending a day hospital. The measures of functioning are extensive enough for people with organic problems e.g. Alzheimer's, but I'm having problems finding a good measure for over 65's with chronic depression and anxiety.

I'd appreciate some help.
