The structure interview assessment of global Type A behavior and six components of Type A behavior were related to eight indices of psychological symptoms and life enjoyment. The Type A component of verbal response latency (faster responding) was found to be positively correlated with the "Life Enjoyment" index and negatively correlated with the "Life Dissatisfaction," "Psychosomatic Symptoms," and "Depressed Affect" indices. The Type A component of hostility was found to be positively correlated with the indices of "Irritability" and "Anxiety." The hostility and response latency components were the primary, independent predictors of the psychological symptoms and life enjoyment indices in a series of multiple regression analyses in which the global Type A assessment and Type A components were entered as predictors and the effects of demographic variables were held constant. The composition of a global score from component scores which relate to external variables in opposite directions yields attenuated correlations of those external variables with the global score. Failure to attend to interactions of the global or component scores with other classes of variables, such as demographics, can also mask relationships with external variables.
