This type of personality concerns how people respond to stress.
Friedman & Rosenman (both cardiologists) developed their theory based on an observation of the patients with heart conditions in their waiting room.
Unlike most patients, who wait patiently, some people seemed unable to sit in their seats for long and wore out the chairs. They tended to sit on the edge of the seat and leaped up frequently.
What was unusual was that the chairs were worn down on the front edges of the seats and armrests instead of on the back areas, which would have been more typical. They were as tense as racehorses at the gate.
The two doctors labeled this behavior Type A personality. They subsequently conduced research to show that people with type A personality run a higher risk of heart disease and high blood pressure than type Bs.
Although originally called 'Type A personality' by Friedman & Rosenman it has now been conceptualized as a set of behavioral responses collectively known as Type A Behavior Pattern.
Type A Behavior Pattern (TABP)
Typical responses of TABP include:
Type A individuals tend to be very competitive and self-critical. They strive toward goals without feeling a sense of joy in their efforts or accomplishments.
Interrelated with this is the presence of a significant life imbalance. This is characterized by a high work involvement. Type A individuals are easily ‘wound up’ and tend to overreact. They also tend to have high blood pressure (hypertension).
Type A personalities experience a constant sense of urgency: Type A people seem to be in a constant struggle against the clock. Often, they quickly become impatient with delays and unproductive time, schedule commitments too tightly, and try to do more than one thing at a time, such as reading while eating or watching television.
Type A individuals tend to be easily aroused to anger or hostility, which they may or may not express overtly. Such individuals tend to see the worse in others, displaying anger, envy and a lack of compassion.
When this behavior is expressed overtly (i.e. physical behavior) it generally involves aggression and possible bullying (Forshaw, 2012). Hostility appears to be the main factor linked to heart disease and is a better predictor than the TAPB as a whole.
Type B & C Personalities
People with Type B personality tend to be more tolerant of others, are more relaxed than Type A individuals, more reflective, experience lower levels of anxiety and display higher level of imagination and creativity.
The Type C personality has difficulty expressing emotion and tends to suppress emotions, particularly negative ones such as anger. This means such individual also display 'pathological niceness', conflict avoidance, high social desirability, over compliance and over patience.
Friedman & Rosenman (1976) conducted a longitudinal study to test their hypothesis that Type A personality could predict incidents of heart disease.
The Western Collaborative Group Study followed 3154 healthy men, aged between thirty nine and fifty nine for eight and a half years.
Examples of questions asked by Friedman & Rosenman:
- • Do you feel guilty if you use spare time to relax?
• Do you need to win in order to derive enjoyment from games and sports?
• Do you generally move, walk and eat rapidly?
• Do you often try to do more than one thing at a time?
From their responses, and from their manner, each participant was put into one of two groups:
Type A behavior: competitive, ambitious, impatient, aggressive, fast talking.
Type B behavior: relaxed, non-competitive.
According to the results of the questionnaire 1589 individuals were classified as Type A personalities, and 1565 Type B.
The researchers found that more than twice as many Type A people as Type B people developed coronary heart disease. When the figures were adjusted for smoking, lifestyle, etc. it still emerged that Type A people were nearly twice as likely to develop heart disease as Type B people.
For example, eight years later 257 of the participants had developed coronary heart disease. By the end of the study, 70% of the men who had developed coronary heart disease (CHD) were type A personalities.
As a result, they are more likely to have the stress hormones present, which over a long period of time leads to a range of stress-related illnesses.
Limitations of the study involve problems with external validity. Because the study used an all male sample it is unknown if the results could be generalized to a female population.
