Two groups of patients suffering from primary unipolar major depressive disorder, one with (n = 145) and one without (n = 119) psychotic disorders were compared, in order to elucidate whether psychotic depressive disorder represents a distinct subtype or a severe variation of the illness. Except for more frequent appearance of psychomotor disturbances among the psychotic depressives, no demographic, family history and course variables were found to distinguish between those with or without psychotic features. The findings from our study are compatible with the view that psychotic depressive disorder is a severe variant of major depressive illness.
对两组原发性单相重度抑郁症患者进行了比较，一组有精神病性障碍（n = 145），另一组无精神病性障碍（n = 119），以阐明精神病性抑郁障碍是该疾病的一种独特亚型还是严重变体。除了精神病性抑郁症患者中精神运动性障碍出现得更频繁外，未发现人口统计学、家族史和病程变量能区分有无精神病性特征的患者。我们的研究结果与以下观点相符，即精神病性抑郁障碍是重度抑郁性疾病的一种严重变体。
