The study highlights a complex relationship between the coronary-prone Type A behavior pattern and impulsivity, driven by opposing directions in risk-taking and non-planning components.
Opposing impulsivity facets in Type A suggest refined behavioral profiling for CAD risk; leaves open prospective validation.
It has recently been suggested that individuals showing the Type A behavior pattern may be less impulsive than those not showing the pattern. In this way the failure of the Type A individual to make many errors in reaction time tasks may be accounted for. A correlational study with 56 male and female college undergraduates does show a trend towards a negative relationship between Type A and impulsivity, but within the construct of impulsivity two components, risk-taking and non-planning, show relationships with Type A in opposing directions.
