The aim of this study was to investigate the relationships between personality and behavioral responses in patients with acute myocardial infarction. In a first step, a new instrument (PSY Inventory) for assessment of six behavioral characteristics (Sense of Responsibility, Energy and Competitiveness, Obsessive Behavior, Anger and Hostility, Stress-related Disturbances, Time Urgency) was developed by using factor analysis on intercorrelations of responses from 524 subjects of the general population. Internal consistency reliability for each of the PSY subscales was estimated by Cronbach alpha coefficients. In a second step, the PSY Inventory was administered with the Cattell 16 PF Questionnaire to 838 patients affected by acute myocardial infarction. Significant correlations although relatively low in magnitude for PSY Inventory subscales and certain scales of the Cattell 16 PF were found. With factor analysis on 22 variables (including the six PSY Inventory subscales and the 16 scales of the Cattell 16 PF), five second-order factors were identified, namely, Extraversion, Neurotic Anxiety, Superego Strength, Pathemia, and Neurotic Hostility. While a Pathemia Factor (characterized by sensitivity, imagination, and self-sufficiency) was factorially independent of scales of the PSY Inventory, Extraversion, Neurotic Anxiety, Superego Strength, and Neurotic Hostility Factors were composed of the PSY Inventory scales and Cattell 16 PF scales combined. These relationships would reflect the concordance of internal constructs for behavioral measures of the PSY Inventory and those of personality traits of the 16 PF Questionnaire in patients with acute myocardial infarction.
本研究旨在调查急性心肌梗死患者的人格与行为反应之间的关系。第一步，通过对来自524名普通人群的受试者的反应进行相互关联分析，运用因子分析法开发了一种新的工具（PSY量表），用于评估六种行为特征（责任感、精力与竞争力、强迫行为、愤怒与敌意、与压力相关的障碍、时间紧迫感）。通过克朗巴哈α系数估计PSY各分量表的内部一致性信度。第二步，将PSY量表与卡特尔16种人格因素问卷一起施测于838名急性心肌梗死患者。结果发现，PSY量表各分量表与卡特尔16种人格因素问卷的某些量表之间存在显著相关性，尽管相关性程度相对较低。通过对22个变量（包括PSY量表的六个分量表和卡特尔16种人格因素问卷的16个量表）进行因子分析，确定了五个二阶因子，即外向性、神经质焦虑、超我力量、情感性和神经质敌意。虽然情感性因子（以敏感性、想象力和自给自足为特征）在因子上独立于PSY量表，但外向性、神经质焦虑、超我力量和神经质敌意因子是由PSY量表和卡特尔16种人格因素问卷的量表组合而成。这些关系将反映急性心肌梗死患者中PSY量表行为测量的内部结构与16种人格因素问卷人格特质的内部结构的一致性。
