In a longitudinal study of a sample of Swedish males and females (n = 170), Type A-related behavior at age 13 was related to the scores on an abbreviated Type A scale based on JAS which was administered when the same subjects were 27 years old. Aggression, Motor Hyperactivity, Overambition, and Overachievement measured at age 13 were used as predictors in a multiple regression analysis, with Type A score at age 27 as the dependent variable. The following results were obtained: 1) for men the multiple correlation was 0.41 (p less than 0.01), with Aggression and Overambition accounting for most of the prediction, and b) for women the multiple correlation was 0.36 (p less than 0.05), with Motor Hyperactivity accounting for most of the prediction. It was concluded that Type A-related behavior could be identified rather early and that it shows an unexpected degree of stability over a period of 14 years.
在一项针对瑞典男性和女性样本（n = 170）的纵向研究中，13岁时与A型相关的行为与基于詹金斯活动调查表（JAS）的简化A型量表得分相关，该量表是在同一受试者27岁时进行施测的。在多重回归分析中，将13岁时测量的攻击性、运动多动、过度抱负和过度成就用作预测变量，以27岁时的A型得分作为因变量。得到了以下结果：1）对于男性，多重相关系数为0.41（p小于0.01），其中攻击性和过度抱负占了大部分预测作用；b）对于女性，多重相关系数为0.36（p小于0.05），其中运动多动占了大部分预测作用。研究得出结论，与A型相关的行为可以在相当早的时候被识别出来，并且在14年的时间里表现出了出乎意料的稳定性。
