Normative data on cognitive measures of depression

The assessment of cognition and cognitive change is important for case conceptualization, monitoring the efficacy of specific interventions, and evaluating treatment outcome in cognitive-behavioral therapy. Unfortunately, a paucity of normative data exists on cognitive measures used for psychotherapy outcome research in depression, and little information is available to guide a practitioner's understanding of the magnitude and clinical significance of a patient's cognitive change. This article presents normative data on 6 self-report instruments that assess negative and positive automatic thoughts, hopelessness, cognitive biases and errors, and dysfunctional attitudes. Normative data were derived from studies published from the date of inception of a given cognitive index to the year 2000. Recommendations for the use of these normative data are provided.
