Reduction of Physiological,Behavioral,and Self-Report Responses in Type a Behavior: A Preliminary Report

Abstract

Recent reports indicate that Type A Behavior may be reducible by behavioral and other psychotherapeutic methods. To date, however, there has been virtually no demonstration of reduction of the actual, observed behavior. Furthermore, the physiologic hyperresponsiveness that seems to characterize many Type A individuals when under stress, has received relatively little therapeutic attention. This preliminary, uncontrolled report describes a cognitive-behavioral group intervention program, before and after which patients underwent assessment on physiologic, behavioral, and self-report assessments. These included heart rate and blood pressure responsiveness under stressful conditions, trained observer ratings of Type A Behavior, and a variety of subjective measures of Type A Behavior and psychological distress and symptoms. Results showed limited improvement on most behavioral and self-report indices. Relatively greater reduction of Type A Behavior was associated with higher pre-treatment levels of Type A Behavior, with the absence of coronary artery disease and with male gender.
