In a pilot study of 150 manic or depressive patients, the authors used the Research Diagnostic Criteria (RDC) and the Schedule for Affective Disorders and schizophrenia (SADS) to perform preliminary analysis of symptom pictures of the index episode of different diagnostic groups, joint diagnostic classification of the different subtypes of major depressive disorder, and differential outcome by diagnostic groups. The results suggest that schizophrenic symptoms in affective disorders do have diagnostic and prognostic significance, that the term "psychotic depression" should be limited to impaired reality testing without reference to degree of incapacitation, that situational-nonsituational and endogenous-nonendogenous classifications are separate depressive subtypes, and that it may not be true that patients with endogenous major depressive disorder have a better prognosis than patients with nonendogenous depression.
在一项针对150名躁狂或抑郁患者的试点研究中，作者使用研究诊断标准（RDC）和情感障碍与精神分裂症量表（SADS），对不同诊断组索引发作的症状表现进行初步分析、对重度抑郁症不同亚型进行联合诊断分类，并按诊断组区分结局。结果表明，情感障碍中的精神分裂症症状确实具有诊断和预后意义，“精神病性抑郁”一词应限于现实检验受损，而不考虑失能程度，情境性-非情境性和内源性-非内源性分类是不同的抑郁亚型，内源性重度抑郁症患者的预后可能并不比非内源性抑郁症患者更好。
