Psychophysiological responsivity and the type A behavior pattern

Studies were reviewed in which the psychophysiological responses of Type A and B subjects were studied in various contexts. It appears that Type A's manifest greater psychophysiological arousal than Type B's in solitary as well as interpersonal situations in which there is a moderate external incentive to accomplish something. and there is an intermediate probability of failing to accomplish that something. Further, Type A's appear to manifest greater psychophysiological arousal than Type B's in interpersonal situations in which another person annoys or harasses the subject. Why Type A's respond in these situations with greater psychophysiological arousal was discussed in terms of the possibilities that (a) these situations may engage some defining characteristic(s) of Type A's, (b) Type A's may fear and therefore try to avoid failure more vigorously than Type B's, and (c) Type A's may be more motivated to gain and maintain control over important environmental events and therefore are more aroused by threats to such control than Type B's.     

The assessment of type a behavior and the prediction of coronary heart disease: A review

The literature regarding the Type A behavior pattern and its association with the incidence of coronary disease has been accumulating for over 20 years. For any researcher contemplating the investigation of this syndrome and its pathological implications, a daunting and time-consuming task is presented in deciding which Type A measurement technique to use to identify Type A individuals. This article is designed to aid this process by presenting a review of all the prospectively validated Type A measures that have been shown to be predictive of coronary disease. Each measure is described, its development is outlined, and its advantages, disadvantages, and limitations are highlighted. This work was supported by a grant from the Health Education Council, London, under the supervision of Professor J.R. Eiser at the Department of Psychology, University of Exeter.     

Attributional style and the type A coronary-prone behavior pattern

The present two studies examined the attributional styles of Type A and B individuals. Past research suggests that Type A's exhibit greater performance deficits than Type B's following exposure to extended, salient uncontrollable stimuli. The reformulated learned helplessness model suggests that individuals most prone to such performance deficits should exhibit an attributional style characterized by internal, stable, and global attributions for negative outcomes, but external, unstable, and specific attributions for positive outcomes. However, a self-esteem protection explanation of learned helplessness findings predicts an opposite, self-serving attributional style. Results from both studies indicated that Type A's are more self-serving than Type B's in their attributions for positive and negative outcomes.     

Challenge seeking and the type A coronary-prone behavior pattern

The present investigation sought to further delineate the Type A coronary-prone behavior pattern and to elucidate the psychophysiological process through which this behavioral disposition is translated into heart disease. Type A and Type B male subjects engaged in tasks that required varying degrees of activity before an assessment of challenge-seeking tendencies. Type A participants sought greater degrees of challenge than did their Type B counterparts. In addition, the more active the person with Pattern A had been immediately before the challenge-seeking opportunity, the greater the degree of challenge sought. Precedent activity level did not significantly influence challenge seeking in the Type B population. The Type A subjects also had significantly faster heart rates during performance of a challenging task. Pattern A behavior may be translated into heart disease through the cumulative deleterious effects of chronic and excessive challenge-induced cardiovascular excitation.     

The type A behavior pattern, physical fitness, and psychophysiological reactivity

Joint effects of the Type A behavior pattern and aerobic fitness were examined with regard to heart rate (HR) and blood pressure (BP) changes elicited by laboratory challenges. Sixty-one college students were classified as Type A or B using the Structured Interview (SI), and as physically fit or sedentary using self-reports of activity level and estimated VO2max values obtained on a step test. Subjects were challenged with the SI, presentation of a snake, mental arithmetic, a cold pressor task, and two competitive card games. Significant A-B differences were found only on the SI and the card games. During the SI: As displayed significantly greater BP increases than Bs; sedentary subjects showed greater BP increases than fit subjects; and sedentary As revealed greater BP increases than either fit As, fit Bs, or sedentary Bs. In contrast, during the competitive games, physically fit As showed reliably greater BP increases than either sedentary As, sedentary Bs, or fit Bs. Since the physically fit subjects were almost exclusively varsity athletes and the sedentary subjects were college students who reported following a sedentary lifestyle, the differences between sedentary and fit groups may have been due to differences in aerobic fitness or to the improved ability of competitive athletes or those engaged in fitness training to match arousal level to task requirements.     

Personality, type A behavior, and coronary heart disease: the role of emotional expression

The nature of the relation between personality factors and coronary heart disease (CHD, the nation's greatest killer) is one of the most important if controversial issues in the field of psychology and health. Although there is still a great deal of conceptual confusion, progress is being made in refining the key components of a predisposition to heart disease. In this article we examine the construct of a coronary-prone personality in the context of the relations among personality, emotional expression, and disease. Special consideration is given to mode of measurement of the Type A behavior pattern--Structural Interview (SI) versus Jenkins Activity Survey (JAS)--and to components and non-Type A correlates of the general coronary-prone construct. Fifty middle-aged men who had had a myocardial infarction were compared with 50 healthy controls in terms of relevant aspects of their psychological functioning. Results indicate that the SI is better than the JAS as a predictor of coronary heart disease (CHD) because of its attention to emotional expressive style. Traditional emphases on hurry sickness in coronary proneness are deemed wholly inadequate. Furthermore, the results indicate that depression, anxiety, or both may relate to CHD independently of and in addition to Type A behavior. Other aspects of personality and social support are also discussed in the context of improving the construct of coronary proneness.     

The type a behavior pattern and the need to prove oneself: A correlational study

This study set out to investigate the relationship between the Type A behavior pattern, the need for approval, and the need to prove oneself. One hundred and two subjects completed four questionnaires: two measuring A-type behavior, one social desirability, and one—especially devised for this study—the belief in the need to prove oneself consistently. Results showed that Type A’s have significantly lower needs for approval than Type B’s, yet appear to show considerably greater interest in comparing their achievements with others. It seems that Type A’s do not have any special need to prove their worth to others, but that they must constantly prove themselves to themselves. Limitations of this preliminary study are discussed.     

Long-term effects of lifestyle behavior change in coronary artery disease: effects on recurrent coronary events after percutaneous coronary intervention.

This study evaluated the effects of a behaviorally oriented cardiac rehabilitation and secondary prevention program on lifestyle changes and on coronary recurrence rates. Patients recently treated with percutaneous coronary intervention (PCI) were randomized to an intervention with an aggressive focus on lifestyle changes (smoking, diet, exercise, and stress; n=46) or to a standard-care control group (n=42). Results showed that the intervention group had significantly larger overall lifestyle changes than the control group after 12, 24, 36, and 60 months. The intervention group had significantly lower rates of all coronary events (acute myocardial infarction, coronary artery bypass graft, PCI, cardiac death; 30.4% vs. 53.7%), and of cardiovascular mortality (2.2% vs. 14.6%). The need for future large-scale and long-term evaluations of lifestyle-oriented secondary prevention interventions of this kind is emphasized.     

An experimental study about the congruence between type A behavior pattern and type of task

This paper is an experimental study, the basic aim of which is to check whether the congruence between personality characteristics and task characteristics has positive effects for performance and satisfaction on individuals. The results obtained reveal that Type A behavior pattern individuals get better results in cases of congruence than in cases of incongruence, while the performance of Type B behavior pattern individuals is not related to the (in)congruence between personal needs/aims and the task's demands. Besides, we have found that Type A behavior pattern individuals also have greater levels of satisfaction in cases of congruence than in cases of incongruence. However, Type B behavior pattern individuals show the same levels of satisfaction in both cases.     

Gender differences in the relationship between hostility and the type A behavior pattern

A group of 97 male and 111 female undergraduates completed the Jenkins Activity Survey, the Framingham Type A Scale, the Adjective Checklist Type A Scale, the Spielberger State-Trait Anxiety Inventory, and the Buss-Durkee Hostility Inventory. A factor analysis revealed three dimensions: Anger-Emotionality, Anger-Aggression, and Residual Pattern A. All Type A measures loaded highly on the Type A factor, with the Jenkins Activity Survey loading the highest. The Framingham Type A Scale was related to Anger-Emotionality, the Adjective Checklist Type A Scale was related to Anger-Aggression, and the Jenkins Activity Survey was related to neither of the anger dimensions. Women scored higher than men on Anger-Emotionality and the Guilt, Resentment, and Irritability subscales and lower than men on the Assaultiveness subscale. Women showed higher correlations between Type A and the Guilt subscale, and men between Type A and the Suspiciousness subscale. We conclude that Type A is a multidimensional construct that manifests itself differently in men and women.     

The Myers-Briggs type indicator and coronary heart disease

Researchers have for many years attempted to establish a relationship between coronary heart disease (CHD) and personality type. In our study, 103 subjects completed Form G of the Myers-Briggs Type Indicator (MBTI). Comparisons were made between 93 CHD patients and an age-appropriate control group (Group C) on each of the four MBTI dimensions: Extraversion-Introversion, Sensing-Intuition, Thinking-Feeling, and Judging-Perceiving. The comparison between CHD patients and Group C showed that CHD patients were significantly more likely to prefer sensing and feeling.     

Effects of parental styles on anxiety and type A behavior pattern

The present study examined the effect of reported parental styles on 35 undergraduates' anxiety and the Type A behavior pattern. The modified version of Kelly and Goodwin's Parental Control-style Questionnaire, the State-Trait Anxiety Inventory, and the student version of the Jenkins Activity Survey were administered. Analysis showed that the subjects who had autocratic parents exhibited more Type A behavior pattern as well as having higher scores on the anxiety scales than those who had either permissive or democratic parents.     

Relinquishment of control and the type A behavior pattern: the role of performance evaluation

We investigated the role of information processing in the control relinquishment decisions of Type As and Bs. Pairs of subjects worked independently on a task and received feedback indicating that their partner had performed at a comparable or superior level. On a second task, subjects combined their efforts and made decisions concerning who would work on different parts of that task. One third of the subjects made this decision before completing an evaluation of the initial performances. Another third completed the evaluation without knowing that they would subsequently make a control decision. The final third of the subjects completed their evaluations knowing that a control decision would follow. Results indicated that when the evaluations were completed last, or when the evaluations were completed first but without knowledge of the impending decision, Type As relinquished less control to a superior partner than did Type Bs. When the evaluations were completed with knowledge of an impending control decision, Type As and Bs did not differ in their decisions. These results suggest that under certain conditions, Type As use an automatic or mindless decision style with potentially maladaptive consequences.     

The type A behavior pattern in children: relationships with performance on speed oriented tasks

The Matthews Youth Test for Health (MYTH) was completed by teachers to evaluate 85 fifth- and sixth-grade boys. Type A and B groups of 20 boys each were selected based on MYTH scores. Each boy performed a signalled reaction time task and a perceptual search task. No performance difference was found between the Type A and B boys on the reaction time task. On the perceptual search task, each boy had to scan a set of pictures and report the number of "Snoopy's" seen in each picture. A group difference in response time was found, with the Type A boys having a mean of 5.98 s versus 7.87 for the Type B boys.
