Case management service provision and client change.

The present study examines the relationship between case management service provision to the chronically mentally ill and consequent client change. Subjects were clients who had been in the Mississippi case management system for at least six months. It was predicted that the services of linkage/referral and advocacy would account for the most change in the number of problems and severity of problems on the part of the client. However, less than three percent of the variance in overall client change was explained by all five services combined. Results are discussed in light of certain constraints within the system.
