Final answer:
The personality pattern associated with increased risk of heart disease, characterized by impatience, haste, and hostility, is known as the Type A behavior pattern. Type A personalities have been found to be at a higher risk of cardiovascular diseases due to their aggressive nature and chronic sense of urgency.
Step-by-step explanation:
A person showing a psychological personality pattern characterized by impatience, haste, and frequently aggressive behavior towards others is described by the Type A behavior pattern. This contrasts with Type B, a more relaxed and easy-going behavior pattern. Extensive research, including that conducted by Friedman and his colleagues, demonstrates that individuals with a Type A personality are significantly more at risk for developing heart disease compared to their Type B counterparts. This connection stems from key components of Type A behavior, such as hostility, impatience, and a constant sense of urgent competitiveness. These tendencies can contribute to social strain and consequent cardiovascular responses that promote disease.
For example, a study by Chang et al. (2002) tracked medical students over several decades and found that those who had earlier exhibited higher levels of anger had a substantially greater risk of heart disease by age 55. In conclusion, individuals like Jeffrey exhibit a clear example of Type A behavior with characteristics leading to increased risk of heart disease due to interpersonal hostility and constant urgency.
