Friedman and Rosenman are known for their research on personality types and their relationship to coronary heart disease (CHD). They defined two main personality types: Type A and Type B. Type A individuals are characterized as competitive, aggressive, and highly driven, while Type B individuals are more relaxed and less stressed.
In their findings, they discovered that compared to Type Bs, Type As had higher rates of CHD. This implies that Type As were more likely to experience health issues related to heart disease due to their personality characteristics. Therefore, the correct statement is:
Compared to Type Bs, Type As had higher rates of CHD.
