Scores on four individual difference instruments used in investigations of hypertension and coronary heart disease were compared. 112 college undergraduates completed a Thematic Apperception Test to assess power motivation, the student form of the Jenkins Activity Survey to assess Type A behavior pattern, a version of the Harburg Anger-out Scale, and a new instrument, the Anger Expression Scale. Analyses yielded modest but significant correlations among some of the scales. Students scoring higher on anger-out coping style, as indexed by the anger-out subscale of the Anger Expression Scale and the Harburg Anger-out Scale, had higher scores on power motivation, global Type A, and the Speed and Impatience subscale of the Jenkins Activity Survey. Neither power motivation nor inhibited power motivation was significantly associated with Type A behavior pattern. Implications of the results are discussed within the context of recent findings in personality assessment and health psychology.
