    This study investigated coronary heart disease risk factors and Type A-B Behavior in twins. Certain psychological tests correlated with Type A-B Behavior and risk factors, suggesting potential screening tools.

    Area of Science:

    • Behavioral genetics
    • Cardiovascular disease research
    • Psychological assessment

    Background:

    • Coronary heart disease (CHD) risk factors are multifactorial.
    • Behavior Pattern Type A-B is a known correlate of CHD.
    • Twin studies are valuable for disentangling genetic and environmental influences on complex traits.

    Purpose of the Study:

    • To examine heritability of CHD risk factors and Behavior Pattern Type A-B in middle-aged twins.
    • To identify psychological correlates of Behavior Pattern Type A-B and CHD risk factors.
    • To explore the potential of psychological assessments for screening Type A-B Behavior.

    Main Methods:

    • Studied 190 twin pairs (93 MZ, 97 DZ) aged 44-55 years.
    • Assessed CHD risk factors and Behavior Pattern Type A-B.

  • Administered psychological tests including MMPI, CPI, Cattell PF, Gough Adjective Check List (ACL), and Thurstone Temperament Schedule (TTS).
  • Main Results:

    • Heritability was significant only for Thurstone Temperament Schedule (TTS) scales.
    • Twelve ACL scales and five TTS scales correlated significantly with Behavior Pattern Type A-B.
    • These scales also showed correlations with CHD risk factors like blood pressure and serum lipids.

    Conclusions:

    • Psychological scales, specifically certain ACL and TTS scales, show promise for assessing Behavior Pattern Type A-B.
    • These findings suggest potential for developing new screening questionnaires for Type A-B Behavior.
    • This research contributes to understanding the interplay of genetics, behavior, and cardiovascular health.
