An 11-item questionnaire to ascertain the incidence and significance of major risk factors for atherosclerotic cardiovascular diseases was used to survey a nationwide television audience. Of 250,000 responses, 131,603 were complete and suitable for inclusion in the validity study of the questionnaire. Results of factor analysis and stepwise multiple regression analysis indicate that the questionnaire is a valid instrument for predicting the risk of developing atherosclerotic heart disease.
