An interview schedule was used to record the personality traits of 130 psychiatric patients, 65 with a primary clinical diagnosis of personality disorder and 65 with other diagnoses. The results were analysed by factor analysis and three types of cluster analysis. Factor analysis showed a similar structure of personality variables in both groups of patients, supporting the notion that personality disorders differ only in degree from the personalities of other psychiatric patients. Cluster analysis revealed five discrete categories; sociopathic, passive-dependent, anankastic, schizoid and a non-personality-disordered group. Of all the personality-disordered patients 63 per cent fell into the passive-dependent or sociopathic category. The results suggest that the current classification of personality disorder could be simplified.
采用访谈计划记录了130名精神科患者的人格特质，其中65例初步临床诊断为人格障碍，65例为其他诊断。通过因子分析和三种聚类分析方法对结果进行了分析。因子分析表明两组患者的人格变量结构相似，支持了人格障碍与其他精神科患者的人格仅在程度上有所不同的观点。聚类分析揭示了五个不同的类别：反社会型、被动依赖型、强迫型、分裂样型和非人格障碍组。在所有患有人格障碍的患者中，63%属于被动依赖型或反社会型。结果表明，目前人格障碍的分类可以简化。
