The Reliability and Validity of the Outcome Rating Scale: A Replication Study of a Brief Clinical Measure
Abstract
There is an industry-wide trend toward making outcome evaluation a routine part of therapeutic services, yet most measures are infeasible for everyday clinical use. Consequently, the Outcome Rating Scale (ORS) was developed and recently validated by its authors (Miller, Duncan, Brown, Sparks, & Claud, 2003). This article reports the findings of an independent replication study evaluating the reliability and concurrent validity of the ORS as studied in a non-clinical sample. Concurrent validity was tested by comparing the ORS with the Outcome Questionnaire 45.2 (OQ) using correlation statistics. The findings re-confirm that the ORS has high test-retest reliability, strong internal consistency, and moderate concurrent validity. Implications for clinical practice and future research are discussed.
