The Differential Personality Inventory was administered to four samples of subjects: 404 alcoholic patients, 292 college students, 720 prison inmates, and 181 general psychiatric patients. Exploratory factor analysis on the self-report data yielded seven factors in each sample. The six factors, interpreted as common across samples, were: hypochondriacal complaining, blunted affect versus emotional reactivity, interpersonal conflict, depressed withdrawal, cognitive disorganization, and dysfunctional coping. Implications for the empirical development of a multiaxial diagnostic system and the construction of a case-identifying instrument in psychiatric epidemiological research were discussed.
404名酗酒患者、292名大学生、720名监狱囚犯和181名普通精神科患者。对自我报告数据进行探索性因素分析后，每个样本均得出七个因素。六个被认为在各样本中普遍存在的因素分别是：疑病性抱怨、情感迟钝与情绪反应性、人际冲突、抑郁退缩、认知紊乱和功能失调性应对。讨论了在多轴诊断系统的实证发展以及精神疾病流行病学研究中构建病例识别工具方面的意义。
