Description: This research addressed whether the measurement properties of the John Henryism Scale and the Framingham Type A Questionnaire were the same for various types of subjects. The sample, consisting of 1017 respondents fifty years and older, came from the 1984/1985 Charleston Heart Study.

Hypothesis One. The John Henryism and the Framingham Type A Questionnaires would be reliable and valid instruments for measuring the concept of hard driving in black and white elderly individuals. (The resulting data indicated reliability of both instruments for black and white elderly respondents. Concurrent validity was supported for white, but not black respondents).

Hypothesis Two. Construct validity would be present in the John Henryism Scale as evidenced by (a) correlation of the John Henryism with the items of the Framingham Type A that measure hard-driving behavior, (Hypothesis supported for white respondents); (b) lack of correlation of the John Henryism with the items of the Framingham Type A that measure time-urgency (Hypothesis supported for all respondents); and (c) factor analysis that demonstrates an unidimensional construct for the John Henryism and the Framingham Type A (Hypothesis not supported).

Hypothesis Three. Race, sex, and education would be related to a person's hard-driving behavior as measured by a person's score on the John Henryism and the Framingham Type A and to time-urgency as measured by a person's score on the Framingham Type A (Hypothesis supported).

Hypothesis Four. A person's blood pressure would be related to the interaction of education and the person's hard-driving behavior as measured by the person's score on the John Henryism Scale. Within the low education group, John Henryism would be associated with higher blood pressures, but within the high education group, John Henryism would be associated with lower blood pressures (Hypothesis not supported, no significant correlations found for either group).

Hypothesis Five. A person's blood pressure would have no relation to the person's hard-driving behavior and time urgency as measured by the person's score on the Framingham Type A except for the following group: white males. White males with higher Framingham Type A scores would have higher diastolic blood pressure (Hypothesis not supported, no significant correlations found for any group).
