Selection of outcome assessment instruments for inpatients with severe and persistent mental illness.

The purpose of this article is to describe a procedure to assist in selecting outcome measures for inpatients treated at a state psychiatric hospital. The procedure combines evidence-based criteria from the literature, instruments shown to be sensitive to change in clinical trials, and the perspectives of a multidisciplinary team of researchers, administrators, providers, and patient advocates. Recent efficacy and effectiveness studies were used to identify recurrently used outcome instruments.
