Role ambiguity, Type A behavior, and job satisfaction: Moderating effects on cardiovascular and biochemical responses associated with coronary risk

Abstract

Studied 217 male managers (mean age 44 yrs), classified as Type A (coronary-prone) or Type B (non-coronary-prone), to examine the effects of job satisfaction as a moderator between a common job stressor (role ambiguity) and coronary risk indicators. For Type A's, the results support the hypotheses that changes in ambiguity are associated with changes in blood pressure and that intrinsic job satisfaction has both a direct and moderating effect on these changes. Few similar effects were found for extrinsic job satisfaction. For Type B's, the effects on systolic blood pressure were opposite to those for type A's. It is suggested that either Type A's and Type B's differ in autonomic and cardiovascular response or that ambiguity as a stressor may have differential effects for Type A's and Type B's, indicating that their "fit" with ambiguous environments may be opposite.
