Time Urgency and Type a Behavior

Abstract
The time urgent compotent of the Type A coronary-prone behavior pattern was investigated through examination of temporal placement of participation in a questionnaire study. Subjects volunteered to complete a questionnaire battery during an eight-week time period in order to gain extra-credit toward their course grade. Results indicated that Type As participated earlier in the time period than Type Bs. It was suggested that Type A-B status could be confounded with systematic changes in a study that occur as a function of time. Random assignment of subjects to participation times appears to be essential in such cases.
