Although the Type A behavior pattern has been linked to serious health disorders, recent evidence suggests that the Type A style only produces negative health consequences when its fit with the environment is poor. A study was undertaken to determine whether there was a difference between Type A and Type B persons in general lifestyle pace preference. College students (N=140) completed a number of stress measurements, the Jenkins Activity Survey (JAS) Form D, and a brief survey assessing preferred pace style and current style. Students were categorized as Type A or Type B by their JAS scores. Pace incongruence was determined by subtracting the preferred pace score from the current pace score. The results indicated that, compared to Type B students, Type A students preferred a faster paced environment and reported a faster paced current environment. Students who were pace-incongruent reported significantly greater stress on all stress measures. Approximately twice as many Type A students as Type B students were pace-incongruent, and Type A students reported more stress related to their current pace. When pace-congruent Type A students were compared with pace-congruent Type B students, Type A students still reported significantly more stress with the exception of pace-control stress, where congruent Type A's were significantly less stressed. These results support the person-environment fit stress hypothesis, and confirm the Type A preference for faster paced environments and the Type A propensity to be in lifestyles which are pace-incongruent.
