Measurement of the Type A behavior pattern from adolescence through midlife: further development of the adolescent/adult Type A behavior scale (AATABS).

We reported in 1990 the development of the Adolescent/Adult Type A Behavior Scale (AATABS). While the measure showed considerable promise, improvements to its component structure were indicated. The present study reports such modifications and also provides data on the use of the new scale, the AATABS-R, with middle-aged subjects as well as young adults from the United States.
