A reliability assessment of the Psychotherapy Supervisory Inventory.

The authors investigated the reliability of the Psychotherapy Supervisory Inventory scales, which rate behaviors of supervisors on the basis of observation of supervision sessions. The scales assess focus on the therapist and the patient, intellectual and experimental orientation, number of clarifying and interpretive comments, intensity of confrontation, depth of exploration, verbal activity level of the supervisor, dominance of the supervisor and the therapist, comfort and tension levels, and empathy of the supervisor. Intraclass correlation coefficients were significant for all scales, indicating that trained observers can agree in distinguishing supervisory behaviors. These scales can be used in further research and for feedback to supervisors.
