The DSM-III employs a categorical model for the classification of personality disorders. A dimensional model provides certain advantages, but there has not yet been an empiric attempt to identify an optimal set of dimensions. We systematically assessed the presence of each of the symptoms for the personality disorders in 84 patients. The number of symptoms of each of the personality disorders possessed by each patient was correlated across patients, and the correlations were subjected to a multidimensional scaling program. A three-dimensional solution was compared with the placements of the personality disorders predicted by dimensions published previously.
《精神疾病诊断与统计手册》第三版采用分类模型对人格障碍进行分类。维度模型具有一定优势，但尚未有基于实证的尝试来确定一组最优维度。我们系统评估了84例患者中人格障碍各症状的存在情况。对每位患者所具有的每种人格障碍的症状数量在患者之间进行相关性分析，并将这些相关性分析结果应用于多维标度程序。将三维解决方案与先前发表的维度所预测的人格障碍分类位置进行比较。
