Changes in mode of control and self-control for post myocardial infarction patients evidencing Type A behavior: the effects of a cognitive/behavioral intervention and/or cardiac counseling.
A control model of psychological health was utilized to assess the effects of a cognitive/behavioral intervention and/or cardiac counseling with post myocardial infarction patients evidencing Type A behavior. A previously developed four quadrant control inventory measuring perceived mode of control and perceived self-control was given to groups in two sections of the Recurrent Coronary Prevention Project. The experimental group (coronary counseling plus cognitive/behavioral intervention) was tested after one year (E1) and two years (E2) of treatment. The cardiac counseling group was assessed only after two years (C2). As hypothesized, the cognitive/behavioral treatment section at E2 had a significantly higher overall satisfaction level and congruence between real and ideal self on each of the four quadrants than at E1, and than the cardiac counseling only (C2). Further, on each of the four quadrants, E2 had a psychologically healthier mode of control profile than the cardiac counseling only (C2); and a healthier profile on both the positive assertive and positive yielding mode of control than at E1. Finally, E2's self-control score was significantly higher than C2's. Comments on future directions in measuring perceived control, and on the relationship of control and Type A behavior are offered.
