Type A behavior, age, and psychological well-being.

Investigated psychological well-being among Type A (coronary prone) and Type B (noncoronary prone) individuals across the age span. It was hypothesized that the hard-driving, achievement-oriented lifestyle exhibited by Type A's would be adaptive in younger age groups but would lead to lower well-being in later life because of increased limitations on the range and level of activities. By contrast, the more relaxed, easygoing style of Type B's would match better the slower pace of old age but would not be as conducive to success in younger age groups. 319 adults (aged 18–89 yrs) completed a battery of instruments that included the Jenkins Activity Survey and scales of life changes and psychopathology. Results confirm the hypotheses but indicate that psychological differences may be mediated in part by differences in physical well-being. Experience with life events and the structure and function of social networks may contribute to the differences in well-being. (59 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
