Cross-validation of the A/B typology in The Netherlands.

In a retrospective patient-control study in The Netherlands, relationships were established between the coronary-prone behavior pattern, as measured with the Structured Interview (SI) and the Jenkins Activity Survey (JAS), and selected Dutch questionnaires, i.e. The Maastricht Questionnaire (MQ) on vital exhaustion as a prodrome for myocardial infarction, the Western Time Attitude Scale (WTAS), and the Achievement Motivation Test (AMT), among others. The SI and the MQ discriminated best between patients (n = 58) and controls (n = 58); negative fear of failure (AMT subscale) was significantly associated with patients but not so with controls, as was time anxiety (WTAS subscale).
