title: Capability of questionnaire of social and psychological factors to predict coronary heart disease and stroke.
abstract: It is well known that the incidence of stroke is higher in Japan than in the US, and that, conversely, the incidence of heart disease is higher in the US than in Japan. To clarify this fact, a socio-cultural investigation is indicated. This study was therefore conducted from that viewpoint. A questionnaire was devised and a survey conducted to investigate the effect of social, cultural, and psychological factors on coronary heart disease and stroke. The survey was based on the hypothesis that cultural differences between Japan and the US contribute heavily to differences in the incidence of stroke and heart disease between the two countries. The questionnaire was analysed and correlated with physical examination findings, using Hayashi's quantification method type II. Discrimination between two distinct groups for each disease was clear and the predictive capability of the questionnaire was thus ascertained. In this report we concentrated on use of the prediction table use of sample data, and prediction of the probability of abnormality.
