A study of the relationships among Type A behavior pattern, alexithymic tendency and stress diseases.

本研究旨在探讨A型行为模式、述情倾向与应激性疾病之间的关系。采用自编问卷对心身疾病患者和健康受试者进行测试。采用Egogram和明尼苏达多相人格问卷(MMPI)对心身疾病患者进行测评。通过检测溴隐亭对血清生长激素水平的影响，测定所有心身疾病患者下丘脑-脑垂体多巴胺能系统的反应性。根据患者血清生长激素水平的分泌模式，将患者分为有反应者(功能正常)和无反应者(功能障碍)，比较有反应者和无应答者的Egogram评分，统计分析显示，两者的得分没有显著差异。在MMPI上，显示两组之间有显著差异趋势的唯一规律性量表是抑郁量表。这一结果表明，无反应者表现出较少的情绪障碍-例如，较少抱怨不适、焦虑和紧张。这一结果表明，为什么很难使用自我报告测试来衡量无反应者的心理特征。采用多维度量表对健康受试者、心身应答者和心身无应答者进行区分。从这一分析中提取了两个解决方案。第一种解决方案区分了健康受试者和心身病人。第二种解决方案成功地区分了应答者和非应答者。第一种解决方案表明，与健康受试者相比，心身疾病患者的生活压力更大，行为模式更活跃。第二种解决方案表明，无反应者没有意识到他们所面临的压力情况。

This research was intended to study the relationships among Type A behavior pattern, alexithymic tendency and stress diseases. A newly constructed question list was administered to psychosomatic patients and healthy subjects. Egogram and Minnesota Multiphasic Personality Inventory (MMPI) were administered to psychosomatic patients. The responsiveness of the dopaminergic system of the hypothalamo-pituitary gland was measured in all psychosomatic patients by examining the effect of bromocriptine on serum growth hormone level. Patients were classified as either responders (normal function) or non-responders (dysfunction) based on their secretion patterns of serum growth hormone levels.Statistical analysis that compared responders and non-responders revealed no significant differences on the scores of Egogram. On the MMPI,the only regular scale revealed a tendency of significant difference between the two groups was the depression scale. This result indicated tant non-responders showed less emotional disturbance---for example less complaints of unwellness, anxiety and tension. This results suggests why it is difficult to use self-report tests for measuring the psychological characteristics of non-responders. Multidimensional scaling of the newly constructed question list was applied to discriminate between the healthy subjects, psychosomatic responders and psychosomatic non-responders. Two solutions were extracted from this analysis. The first solution discriminated between healthy subjects and psychosomatic patients. The second solution successfully discriminated between responders and non-responders. The first solution indicates that psychosomatic patients live more stressful lives and have more active behavior patterns compared with the healthy subjects. The second solution indicated that non-responders were not aware of the stressful situation to which they were exposed.
