Do expressive speech characteristics during an interview better discriminate Type A behavior compared to the Jenkins Activity Survey?
Expressive speech characteristics during interviews provide an independent method from the Jenkins Activity Survey for classifying Type A behavior, a psychological predictor of coronary heart disease.
Speech characteristics of both an interviewer and respondents were scored from recorded interviews that were conducted to assess Type A behavior. A stepwise regression analysis indicated that the expressive speech characteristics were the best discriminators of behavior typing by the interview. A similar analysis employing the Jenkins Activity Survey as the criterion for typing showed that only the content of the respondents' answers predicted typing. The Activity Survey and the interview assessment appeared to classify individuals on independent aspects of Type A behavior. Correlations of the interviewer's speech characteristics with the respondents' feeling reports and speech characteristics show stronger associations among these variables for Type A than for Type B subjects. The analysis of speech characteristics id discussed as a method of refining the assessment of behavior type and of identifying the psychological predictors of coronary heart disease.
