Evaluation of attentional and neuromotor functions in 45 patients meeting the Research Diagnostic Criteria for schizophrenia, schizoaffective disorder, and other affective disorders showed that schizoaffectives could not be distinguished from patients with other affective disorders by any of the measures. However, schizophrenics differed from the other diagnostic groups on four measures: they showed significantly more oculomotor, stereognosis, and right-left identification abnormalities and more errors of omission on the attentional task under distraction conditions. The findings of this study are consistent with earlier reports that schizoaffectives are not generally different from patients with other affective disorders in family history, treatment response, or long-term outcome. There is not yet sufficient etiologic or behavioral evidence to indicate that schizoaffective disorder is a valid diagnostic category.
对45名符合精神分裂症、分裂情感性障碍及其他情感障碍研究诊断标准的患者进行的注意力和神经运动功能评估显示，分裂情感性障碍患者无法通过任何一项测量指标与其他情感障碍患者区分开来。然而，精神分裂症患者在四项测量指标上与其他诊断组不同：在分心条件下的注意力任务中，他们表现出明显更多的眼球运动、实体觉和左右辨别异常以及更多的遗漏错误。本研究结果与早期报告一致，即分裂情感性障碍患者在家族史、治疗反应或长期预后方面通常与其他情感障碍患者没有差异。目前尚无足够的病因学或行为学证据表明分裂情感性障碍是一个有效的诊断类别。
