Measuring Feedback From Clients

Abstract

Treatment results can be improved by obtaining feedback from clients concerning their progress during therapy and the quality of the therapeutic relationship. This feedback can be rated using short instruments such as the Outcome Rating Scale (ORS) and the Session Rating Scale (SRS), which are being increasingly used in many countries. This study investigates the validity and reliability of the Dutch ORS and SRS in a large sample of subjects (N = 587) drawn from the clients of an outpatient mental healthcare organization. The results are compared to those of previous Dutch and American studies. While both the ORS and the SRS exhibited adequate test-retest reliability and internal consistency, their concurrent validity was limited (more for the SRS than for the ORS). New standards are proposed for the Dutch ORS and SRS. The scores obtained with these standards are interpreted differently than those obtained using American standards. The clinical implications of the limited validity of the ORS and the SRS are discussed, as is the use of different standards in conjunction with these instruments.
