Several self-report measures of type A behavior were compared with the Rosenman and Friedman structured interview method of assessment in male and female college students. The student version of the Jenkins Activity Survey was found to correlate relatively weakly with the interview for both males and females, while scales derived from the Gough and Thurstone inventories showed moderate correlations with interview typing for both sexes. A brief scale derived from a recent reanalysis of the Framingham study correlated with the interview appreciably greater for females than for males. In all, these data suggest the need for caution in using only paper-and-pencil tests to assess type A behavior.
