Type A in relation to job-stress, social and bioclinical variables: the Belgian Physical Fitness Study.

The present study focuses on the relationship of Type A behavior, a suspected coronary-prone behavior pattern in its overall or specific aspects, to "stress" experienced at work, and to social and coronary bioclinical risk factors. In order to measure Type A behavior and Job-Stress, respectively, the Jenkins Activity Survey Questionnaire (J.A.S. for employed persons, 1969 version) and a self-constructed Job-Stress Questionnaire were administered at a base-line examination to 2,302 men aged 40-50 years. The multivariate analysis shows: A strong Type A behavior-Job-Stress relationship; An important relationship between employment grade, educational attainment and--to a lesser extent--, marital status and, overall Type A behavior, Speed and Impatience and Job-Involvement, A weak relationship between cholesterol and triglycerides (not found in univariate analysis), and, overall Type A behavior; a small weak relationship between smoking habits, and, Speed and Impatience and Hard-Driving. A direct relationship between heavy physical activity during leisure-time and Job-Involvement.
