Key result
Type A students with frequent self-references exhibited higher systolic blood pressure, higher distress, and lower heart rate than Type A students with less frequent self-references.
Why the study?
Does self-involvement, measured by self-references, affect cardiovascular response during stress tasks in Type A versus Type B students?
Population
Coronary-prone Type A and noncoronary-prone Type B students
Comparison
Battery of stress tasks including cold pressor… vs Noncoronary-prone Type B students

Does self-involvement, measured by self-references, affect cardiovascular response during stress tasks in Type A versus Type B students?
Frequent self-references in Type A individuals are associated with heightened cardiovascular reactivity during stress tasks, suggesting a role for self-involvement in coronary-prone behavior.
Scherwitz et al. (1978) conducted an observational in Coronary-prone Type A and noncoronary-prone Type B behavior. Type A behavior with frequent self-references vs. Type A behavior with less frequent self-references and Type B behavior was evaluated on Cardiovascular response (blood pressure, heart rate, digital vasoconstriction) and distress. Type A students with frequent self-references exhibited higher systolic blood pressure, higher distress, and lower heart rate than Type A students with less frequent self-references.
