The associations between Type A B behavioural dimension and Type 2 4 personality patterns

This study set out to examine possible associations between Type A B behaviour as measured by the Jenkins Activity Survey (JAS) and Type 2 4 personalities measured by the Short Interpersonal Reactions Inventory (SIPRI). Comparisons were made both within a CHD risk group and a control group consisting of randomly selected subjects from the general population. In the risk group no significant associations between Type A B and Type 2 4 were found. However, in the control group a significant positive correlation was found between the Hard-driving and Competitive scale of the JAS and Type 2, when all subjects were considered together. The difference in findings within the risk group and control group were attributed to behavioural changes in the former, which may have had a different impact on JAS vs SIPRI scores.
