An instrument was developed to measure the cognitive triad conceptualized by Beck to be an important variable in depression (Beck, Rush, Shaw, & Emery, 1979). Reliability and validity statistics are reported on an original sample of 26 depressed patients and a replication sample of 28 depressed patients. The scale and its subscales were found to have high internal reliability. Comparison with rater measures and with two self-report measures, the Rosenberg Self-Esteem Scale (Rosenberg, 1965) and the Hopelessness Scale (Beck, Weissman, Lester, and Traxler, 1974) showed the Cognitive Triad Inventory (CTI) and its subscales to have good convergent validity.
Thirty‐two patients were seen by psychiatry residents, psychology interns, and social work fellows who were learning congnitive therapy of depression. Of these, 23 patients attended sufficient sessions for early response to be categorized as responding or not responding. Rapid response was not associated with positive perception of the therapist by the patient, self‐control scores, or patient collaboration as viewed by the therapist. The BDI score at intake was moderately predicitive of the BDI score at session 6, but it did not predict percent improvement. However, depressive severity at the beginning of session one was strongly predictive of the sixth session BDI, and it also predicted percent improvement. Another prdictor of respose was improvement in mood in the first therapy session, as measured by the VAS. However, outcome variance explained by the VAS did not significantly add to outcome variance explained by the first session BDI. Results are interpreted as indicating that imrpvement may be due to (1) a powerful beneficial effect the originates within the patient‐therapist matrix and independent of therapist techniques; or (2) a continuing improvement process that began prior to entering treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
