Mental health practitioners are increasingly being called on to evaluate the effectiveness of the treatment they provide. The partial hospitalization component of the mental health industry also has felt this call for outcome research. This article presents the results of one program's attempts to answer that call through an assessment of treatment outcome and client satisfaction at a partial hospitalization program. Participants (N = 287) were evaluated at admission, discharge, and 3-month follow-up. The article outlines the procedures used for assessment and uses the results as an example of the type of data that can be obtained through outcomes measurement. The article is intended to provide an example of program evaluation that is easy and inexpensive to administer.
