Two methods of assessing the Type A coronary-prone behavior pattern in Belgium

Abstract

Two methods developed in U.S.A. for measuring the Type A coronary-prone behavior pattern—the Structured Interview and the self-administered Activity Survey, were translated into French and Flemish and utilized in a large preventive cardiology study in Belgium. The distribution of behavior-type judgments made by trained interviewers were compared to similar data from North America and found to be similarly symmetrical but clustering more toward central categories in Belgium. The Activity Survey, when scored by the scoring key developed in California, yielded averages for this Belgian group which appeared to be more in the Type B direction than the California sample, particularly in terms of Job-Involvement and tendencies toward haste and impatience. The Activity Survey scales and Structured Interview judgments showed a strong correspondence, with a 70% agreement observed between the Interview and Type A scores. This comparability between findings in Belgium and U.S.A. suggests that the concept of the Type A behavior pattern has sufficient cross-cultural validity to permit the derivation of reliable measurements and to make feasible the determination of whether Type A behavior is a risk factor for coronary disease internationally.
