title: Environmental demand and demand engendering behavior: an observational analysis of the type A pattern.
abstract: In a prospective, observational study, we examined Type A behavior as a predictor of source of work demands, volume of work and nonwork activity, whether work begun was finished, and attention to more than one activity at a time. Police radio dispatchers (N = 72) were observed throughout one work shift, and half of the sample was observed on two additional work shifts. Behavioral categories showed substantial stability between observation occasions. Hierarchical regression revealed that two components of the broader Type A pattern, Hard-Driving Competitiveness and Job Involvement, were better predictors of work demands and behavior than was the global A score. Results support an interactional personality perspective in that Type As, relative to Type Bs, received more externally imposed demands from particular sources such as superiors or peers. However, these same Type As also generated more demand by simultaneously initiating work tasks for themselves and attending to multiple tasks.
