Development of the Cognitive Therapy Adherence and Competence Scale

Abstract

The authors present basic psychometric data for a new 21-item Cognitive Therapy Adherence and Competence Scale (CTACS; Liese, Barber, & Beck, 1995), which is based on the widely used Cognitive Therapy Scale (CTS; Young & Beck, 1980). The CTACS attempts to provide a wider coverage of cognitive therapists' activities than the CTS. Two expert cognitive therapists rated randomly chosen audiotaped therapy sessions from cocaine-dependent patients randomized to receive cognitive therapy, supportive-expressive dynamic therapy, or individual counseling as part of the training phase and the clinical phase (n = 60 and n = 69, respectively) of the National Institute on Drug Abuse Cocaine Collaborative Treatment Study. Results indicate that the CTACS has acceptable levels of interjudge reliability and criterion validity.
