The present study attempted to assess systematically a set of behavioral subcomponents associated with the Type A behavior pattern. Sixty middle-aged men underwent the structured interview (SI) and a repeated version of the SI after a four-month interval. A high degree of interrater reliability was established for a number of behavioral components including speed and volume of speech, motoric activity, expiratory sighs, response latency, interruptions, unevenness of speech, plosive words, and potential for hostility. In general, these behaviors were stable over the four-month interval, although they did not all distinguish Type As from Type Bs. Only four behaviors successfully discriminated Type As and Bs at both interview sessions: speed of speech, volume of speech, number of interruptions, and potential for hostility. The results are discussed in terms of how these behavioral subcomponents may contribute to increased risk of premature coronary disease.
本研究试图系统评估与A型行为模式相关的一系列行为子成分。60名中年男性接受了结构化访谈（SI），并在四个月后进行了该访谈的重复版本。对于包括语速和音量、运动活动、呼气叹息、反应潜伏期、打断、言语不均衡、爆破性词汇以及敌意倾向在内的一些行为成分，建立了高度的评分者间信度。总体而言，这些行为在四个月的间隔期内是稳定的，尽管它们并非都能区分A型和B型。只有四种行为在两次访谈中都成功区分了A型和B型：语速、音量、打断次数和敌意倾向。根据这些行为子成分如何可能导致冠心病发病风险增加来讨论研究结果。
