    Area of Science:

    • Behavioral psychology
    • Cardiovascular health research

    Background:

    • The Type A behavior pattern is linked to increased risk of coronary heart disease.
    • Specific behavioral subcomponents contributing to this risk require systematic assessment.

    Purpose of the Study:

    • To systematically assess behavioral subcomponents of the Type A behavior pattern.
    • To determine the stability and discriminative validity of these subcomponents.
    • To explore their association with premature coronary disease risk.

    Main Methods:

    • Sixty middle-aged men participated in a structured interview (SI) and a repeated SI after four months.
    • High interrater reliability was achieved for multiple behavioral components.
    • Statistical analysis identified behaviors differentiating Type A from Type B individuals.

    Main Results:

    • Behaviors like speech speed, volume, interruptions, and hostility potential were stable over four months.
    • These four behaviors reliably discriminated Type A from Type B individuals across both interview sessions.
    • Other assessed behaviors showed less consistent discrimination between groups.

    Conclusions:

    • Specific behavioral subcomponents, including speech speed, volume, interruptions, and hostility potential, are reliable indicators of the Type A behavior pattern.
    • These identified behaviors may play a significant role in the increased risk of premature coronary disease associated with Type A individuals.
