This study used cluster analysis in 126 homicide cases based on Personality Assessment Inventory (PAI; Morey, 1999). PAI was implemented by 126 homicides and then dichotomously coded for the presence or absence of cut‐off PAI scale score in order to create criteria for analysis. These cases were input for the agglomerative hierarchical cluster using Ward's method as the clustering algorithm. The results of the analysis classified five clusters: “normal,” “antisocial,” “submissive‐depressive,” “soma‐anxiety” and “isolated.” The representative characteristics were explored and compared with five clusters. As a result, these five clusters significantly differed in various criminogenic variables, such as criminal record and imprisonment experience. But, other variables were not significantly discriminated.

行为特征和罪犯特征：基于杀人案件中人格评估表（PAI）的类型学

这项研究基于人格评估表（PAI； Morey，1999）对126起凶杀案进行了聚类分析。PAI由126起凶杀案实施，然后根据是否存在临界PAI量表分数进行二分编码，以创建分析标准。这些情况是使用Ward方法作为聚类算法输入到聚集层次聚类中的。分析结果将五个类别分类为：“正常”，“反焦虑”，“顺从-抑郁”，“躯体焦虑”和“孤立”。探索了代表性特征，并与五个聚类进行了比较。结果，这五个类别在犯罪记录和监禁经验等各种犯罪因素方面存在显着差异。但是，其他变量没有明显区别。
