&NA;行为表征在冠心病的发病机制和治疗中得到越来越多的使用和研究。已发现一种称为 A 型的特定行为模式与致命性和非致命性冠心病独立相关。 A 类的评估是在没有基于标准化访谈中的言语和非言语行为的定量准则的情况下进行的。本研究试图仅根据可量化的言语行为进行这种分类。两个天真的人接受了训练，根据之前评估过 A 类的行为模式访谈录音来编码言语行为。间编码器和内编码器的可靠性是可以接受的。使用回归分析，87% 的访谈的分类与之前的标准评估一致。研究发现，音量和语速对预测的贡献最大。其他言语特征（包括爆破音）也很重要。结论是，A 型可以通过标准化访谈中的言语行为进行有效且可重复的测量。
&NA; Behavior characterization is increasingly used and studied in the pathogenesis and management of coronary disease. A specific behavior pattern called Type A has been found to be independently associated with fatal and nonfatal coronary disease. The assessment of Type A is made without quantitative guidelines based on verbal and nonverbal behaviors in a standardized interview. This study has attempted to make this classification solely on the basis of quantifiable verbal behaviors. Two naive persons were trained to code speech behaviors from tape recorded behavior pattern interviews on which Type A had previously been assessed. Intercoder and intracoder reliability was acceptable. Using regression analysis 87% of the interviews were classified in agreement with the previous, standard assessment. Volume of voice and speed of speech were found to make the greatest predictive contribution. Other verbal characteristics including plosiveness were also important. It is concluded that Type A can be validly and repeatably measured by verbal behaviors in the standardized interview.
