Brief Summary: To further clarify the concept of coronary-prone behavior and to develop methods of assessing coronary-prone behavior Specifically to revise the component scoring system for Potential for Hostility in the Structured Interviews measure of Type A behavior
Detailed Description: BACKGROUND

In 1978 a select Review Panel of biomedical and behavioral scientists met under the auspices of the NIH to evaluate the data linking the Type A behavior pattern to coronary heart disease Based on the scientific evidence available to them in December 1978 the members of the Panel issued a report in which they concluded that the Type A behavior pattern was an independent risk factor for coronary heart disease of a magnitude similar to that of other established risk factors such as cigarette smoking and serum cholesterol

At the time the Panel met the most impressive evidence linking the Type A behavior pattern to coronary heart disease was the prospective Western Collaborative Group Study WCGS which established a significant risk ratio for Structured Interview-assessed Type A behavior pattern for all clinical manifestations of coronary heart disease and three angiographic studies which reported significant associations between Structured Interview-defined Type A behavior pattern and severity of coronary artery disease Supporting evidence was provided by prevalence studies employing the Jenkins Activity Survey JAS measure of Type A behavior pattern and by incidence and prevalence data from the Framingham study using a six-item scale thought to assess aspects of Type A behavior

Subsequent to the conference studies had begun to emerge which called into question the robustness of the association between the Type A behavior pattern and various manifestations of coronary heart disease The most damaging of these was the prospective Type A study included in MRFIT In this study 3110 men were given the Structured Interview and Jenkins Activity Survey and followed for an average period of seven years while receiving annual medical examinations Analysis of the results at the end of the seven years revealed that Type A behavior pattern however assessed was completely unrelated to either coronary death or documented myocardial infarction

A major tool was the component scoring system for the Structured Interview to determine which of the many attributes comprising the multidimensional Type A behavior pattern were actually associated with coronary heart disease Component scoring had demonstrated that some components had consistent associations with coronary heart disease even when the global Type A behavior pattern showed no relationship Component analysis of the Type A behavior pattern in MRFIT revealed that of all the attributes assessed only Potential for Hostility was significantly related to incidence of coronary heart disease Several other studies were conducted under this project Tape-recorded Structured Interviews from the Western Collaborative Group Study were reanalyzed to assess the relationship between components of Type A behavior and incidence of coronary heart disease Rescoring was completed on Structured Interviews of over 1000 subjects who had undergone stress testing while blood pressure and heart rate were recorded An analysis was also conducted on the influence of cigarette smoking and situational stress on cardiovascular response in young male subjects

DESIGN NARRATIVE

In Study I tape-recorded Structured Interviews from MRFIT were re-scored for Potential for Hostility In Study II Structured Interviews were obtained from a new sample of participants in the BLSA In the BLSA the Structured Interview were expanded to include questions that dealt more directly and sampled more fully antagonistic self-descriptions attitudes and behaviors Alternative measures of Agreeableness-Antagonism were already available from the BLSA sample that were used to validate scores from the expanded Structured Interview and biomedical information on BLSA participants was used to further test the predictive utility of Antagonistic Hostility as a risk factor for coronary heart disease Previous research had scored Potential for Hostility from the Structured Interview by examining Content Intensity and Style as well as a clinical judgement of Total Potential for Hostility In the present study Antagonistic Hostility was measured in terms of Antagonistic Style and Self-Descriptions A total score was defined as the sum of these two components Antagonistic Style was scored using a 5-point scale when rudeness condescension and disagreeableness were expressed toward the interviewer Matched and unmatched logistic regressions were used to evaluate Antagonistic Hostility as a risk factor for morbidity and mortality outcomes Multivariate analyses were used to control for other standard risk factors
