The Multnomah Community Ability Scale is a 17 item instrument that case man
agers can use to rate levels of functioning for clients with severe mental
illness. Prior work in a large urban community mental health center showed
that the instrument predicted subsequent involuntary hospitalization. The c
urrent project involved some 2,487 clients of community mental health progr
ams throughout Oregon. This replication study again showed that low scores
on the instrument predicted subsequent psychiatric hospitalization.
