    Area of Science:

    • Psychology
    • Behavioral Science
    • Developmental Psychology

    Background:

    • Type A personality, characterized by competitiveness and hostility, has been linked to cardiovascular disease.
    • Understanding the developmental trajectory of Type A behavior is crucial for early intervention and prevention strategies.

    Purpose of the Study:

    • To investigate the longitudinal relationship between childhood Type A-related behaviors and adult Type A personality.
    • To determine if specific childhood behavioral components predict adult Type A scores in a Swedish cohort.

    Main Methods:

    • A longitudinal study followed 170 Swedish males and females from age 13 to 27.
    • Childhood predictors included Aggression, Motor Hyperactivity, Overambition, and Overachievement.
    • Adult Type A scores were assessed using an abbreviated Jenkins Activity Survey (JAS)-based scale.

    Main Results:

    • For men, childhood Aggression and Overambition significantly predicted adult Type A scores (multiple correlation = 0.41, p < 0.01).
    • For women, childhood Motor Hyperactivity was the primary predictor of adult Type A scores (multiple correlation = 0.36, p < 0.05).
    • These findings indicate a notable stability of Type A-related behaviors over a 14-year period.

    Conclusions:

    • Type A-related behaviors can be identified as early as age 13.
    • These childhood behaviors demonstrate significant stability into adulthood, suggesting early-life origins of adult Type A personality.
    • Gender-specific patterns in the prediction of adult Type A behavior were observed.
