Toland, Michael D.; Li, Caihong; Kodet, Jonathan; Reese, Robert J.
Measurement and Evaluation in Counseling and Development, v54 n2 p90-105 2021
We assessed the psychometric properties of the visual analog scale (VAS) form of the Outcome Rating Scale (ORS) using item response theory (IRT) with a sample of 2,109 Canadian counseling clients. Findings indicate that the ORS was unidimensional and that the equal-interval assumption was not tenable for the VAS.
