title: Assessment of patient and therapist perspectives of process: a revision of the Vanderbilt Psychotherapy Process Scale.
abstract: The present study was designed to revise the Vanderbilt Psychotherapy Process Scale (VPPS), an external-rater completed measure, into both patient and therapist-rated versions. The VPPS was altered into two versions by using simple pronoun changes and then submitted to a principal components analysis in order to identify component factors. This procedure resulted in two identical forms of the VPPS, one completed by the therapist (VPPS-T) and one completed by patients (VPPS-P). These scales have identical items and factor structures. Preliminary results suggest that the VPPS-P and VPPS-T may be useful measures of psychotherapy process when perspectives of session activity is desired from both patients and therapists.
