This document discusses objections that have been raised regarding the validity and reliability of the Outcome Rating Scale (ORS) as a measure of client outcomes. It addresses concerns that the ORS is too brief and simple to be meaningful, that clients cannot give honest feedback to their therapists, and that the ORS only measures patient satisfaction rather than outcomes. The document also considers more recent questions about whether the ORS measures outcomes on its own or is just a component of a larger intervention. It draws on responses from experts to argue that the ORS has adequate validity and reliability as a stand-alone outcome measure that provides useful real-time feedback to clinicians.
