Measuring Psychodynamic-Interpersonal and Cognitive-Behavioral Techniques: Development of the Comparative Psychotherapy Process Scale

Many instruments have been developed to assess techniques and interventions in a variety of psychotherapies. However, existing scales are limited by several factors such as relatively weak psychometric properties, applicability to only a single form of treatment or manual, and extensive time required for completion. The authors report on the development of a new measure, the Comparative Psychotherapy Process Scale (CPPS). The CPPS is designed to assess the distinctive features of psychodynamic-interpersonal and cognitive-behavioral treatments. Data are presented on the psychometric properties, reliability, and validity of the CPPS. The findings suggest that the scale possesses excellent interrater reliability and internal consistency as well as promising validity. Clinical utility, potential limitations, and future research of the CPPS are discussed.
