Relationship between Type A behavior pattern and mental and physical symptoms: a comparison of global and component measures.

Although the Type A behavior pattern (TABP) is typically considered a set of distinct components, most studies of TABP have used global measures, which collapse several components into a single index. These measures are inherently multidimensional and, as such, contain several conceptual and methodological problems. In this study, data from 240 executives were used to compare global and component TABP measures as predictors of mental and physical symptoms. Global measures included the Bortner scale, the Framingham scale, and the Jenkins Activity Survey. Component measures were constructed by recombining items from the global measures on the basis of results from previous confirmatory factor analyses (Edwards, Baglioni, & Cooper, 1990). Results indicate that the component measures were superior to the global measures in terms of number of relationships detected, interpretability, and total explanatory power. Implications for research and practice are discussed.
