Clinical assessment using the Clinical Rating Scale: Thomas and Olson revisited.

Does the Clinical Rating Scale retain its validity when it is used, not by researchers, but by psychotherapists in their clinical practice? Students in a marital and family therapy training center routinely used the Clinical Rating Scale as part of the intake process. Although they had modest training in its use, confirmatory factor analysis indicated that they produced data that provided a reasonable approximation of the underlying factor structure. Therefore, although primarily considered a research instrument, the Clinical Rating Scale may have a role in clinical assessment and treatment planning.
