TYPE A BEHAVIOUR
- Type A describes someone who wants to achiece more and more in les and less time... three major characteristics:
- 1) competitiveness and achievement striving
- 2) Impatience and time urgency
- 3) Hostility and aggressiveness
- These would lead to raised blood pressure and raised stress hormones
- Type B describes someone lacking these characteristics, being patient, relaxed and easy-going
- Believed to decrease an individuals risk of stress-related illness.
- Research On Type A Behaviour
- 3000 men 39-59 in california were exmined for signs of CHD and thei personalities were assessed by interview.
- It included questions about how they responded to everyday pressures e.g. asked how they would cope for having to wait in a long queue
- Trying to elicit type A behaviour... interviewer may speak slowly and hesitantly for Type A to interrupt
- After 81/2 years, twice as many Type A had a heart attack, compared to 6% of Type B.
- Type A also had higher bllod pressure and cholestrol
- Research support for the Type A/CHD link
- follow-up study of Western Collaborative Group participants in 1982-3, 22 years after the start
- 214 of men had died from CHD
- Study confirmed the importance of the CHD risk factors but found little evidence of a relationship between Type A behaviours and mortality, challening the earlier conclusion that Type A behaviour was a significant risk factor for CHD mortality.
