作者采用基于经验和数学的方法--聚类分析来研究抑郁症的分类。在NIMH抑郁症心理生物学合作研究的228例患者样本中,使用横断面症状生成聚类;病程、家族史和治疗变量作为自变量来评估聚类的有效性。所确定的四个聚类大致对应于具有内源性特征的严重抑郁症、不太严重的抑郁症、在发作内循环的双相抑郁症和精神病性抑郁症。本研究支持研究诊断标准和DSM-III方法对抑郁症的分类。
The authors examine the classification of depressive disorders with an empirically and mathematically based method, cluster analysis. In a sample of 228 patients from the NIMH Collaborative Study of the Psychobiology of Depression, clusters were generated by using crossectional symptoms; course of illness, family history, and treatment variables were used as independent variables to evaluate the validity of the clusters. The four clusters identified correspond roughly to severe depressions with endogenous features, less severe depressions, bipolar depression with cycling within the episode, and psychotic depressions. This study supports the Research Diagnostic Criteria and DSM-III approaches to the classification of depressive disorders.
