“…The most common research design evaluated the effectiveness with which a variety of therapeutic approaches [e.g., physical relaxation (2)(3)(4)(5)(6), cognitive self-instruction (7), insight (4,5), group support (6)] reduced Type A hyperreactivity in small groups of subjects (from 14 to 42) over short periods of time (from 5 to 14 hr). Reductions in the type A behavior pattern (TABP) were assessed using Type A questionnaires [e.g., the Jenkins Activity Survey (3)(4)(5)(6), the Framingham Type A Behavior Scale (6), the Bortner Type A Rating Scale (7), Type A components questionnaires (e.g., the Novaco Anger Scale (6), the Thurstone Adjective Checklist (6)], and measures of psychologic distress [e.g., the State-Trait Anxiety Inventory (3,5)]. To evaluate the clinical significance of the behavioral change, observations were made on indices of sympathetic nervous system reactivity at rest and under challenge [e.g., blood pressure (4-7), heart rate (6), cholesterol (2,4,5,7), free fatty acids (6)].…”
