Freidman and Rosenman (1974) - Findings
At the end of the study, 275 men developed coronary heart disease and 70% of these men were time pressured, competitive and angry towards the world. The results showed that the CHD was not influenced by other factors such as smoking or obesity.
12 of 14
+ A large sample was used which means the results are more likely to be reliable and valid.
+ The link between Type A and CHD is supported by many other later pieces of research.
13 of 14
- Follow up research showed that 22 years after the study 15% of men had died of CHD but this was not found to be related to their personality type.
- The sample was restricted to Californian men and therefore cannot be generalised to everyone.
