Development of a therapist activity rating scale: preliminary findings

A 61-item scale was constructed of relatively explicit descriptions of behavior in which a psychotherapist might engage. The scale is largely noninferential, is basically atheoretical but applicable to psychodynamically oriented therapy, may be completed by either the therapist or an independent rater with minimal training, and may be used to rate entire therapy sessions or specific segments of sessions. The scale shows high interrater reliability and discriminant validity.
