Type A behavior and occupational stress: a cross-cultural study of blue-collar workers.

Psychophysiological, archival, unobtrusive observation, and self-report data were compared for Type A and Type B male bus drivers in the United States and India. Type A bus drivers in comparison with their Type B counterparts have more accidents, absenteeism, official reprimands, and self-reports of occupational stress. In India, but not in the United States, Type A drivers brake, pass, and blow their horns more often than Type B drivers. Although drivers exhibited expected elevations in blood pressure and catecholamines on the job, the magnitude of these increases did not differ as a function of the Type A/B classification.
