Type D Personalities are usually grouchy or grumpy.: image via Harbon.com You may not have paid much attention to your 'personality type,' those rubrics of A, B, and C, developed by psychologists in the 1950's. A comprehensive study of Type D personality (a Type added to the group in the 1990's), its relationship to heart disease, and the findings will no doubt be disappointing to those in that group. This will make them really grumpy.
Briefly, Type A personality (which we probably hear about more than other Types) is the driven type that works and plays excessively and almost compulsively; they also tend towards perfectionism. Type B personalities are more laid back, easy-going types, patient and relaxed. Type A's become impatient with Type B's and Type B's try to stay away from Type A's.
Type C personalities are thorough and perfectionist. They get to the bottom of every challenge they face and are very detail-oriented. Unfortunately Type C's have difficulty expressing their emotions and are often unaware of having them. Accountants and engineers are often Type C personalities.
Now, Type D's have been described as anxious, irritable, and pessimistic. They are the grumps and the grouches of the world. They are not necessarily clinically depressed; negativity is just an overwhelming feature of their personalities.
Though some early studies had shown that Type A's were at the greatest risk for cardiovascular disease, later research found fault with that data. Now an in depth literature research of 49 previous studies involving 6000 patients, found that it's Type D personalities who are the most likely to have cardiovascular disease and are those most likely to have another cardiac incident after experiencing the first one. They are three times more likely than other personality types, according to this research, to experience peripheral artery disease, heart failure, and heart attack.
The research was led by Johan Denollet, a medical psychology professor at Tilburg University
in the Netherlands, and is published as "A General Propensity to Psychological Distress Affects Cardiovascular Outcomes:
Evidence From Research on the Type D (Distressed) Personality Profile" in the journal of Circulation: Cardiovascular Quality and Outcomes.
Denollet strongly suggests that cardiologists learn more about their patients' personalities and give them advice about changing their normal thinking habits.
Grouchy just has to go!
