Eight definitions of schizo-affective psychosis have been compared in a sample of psychotic first admissions. Their mutual concordance is very low (mean 0.19) showing that there is very poor agreement about the meaning of the term 'schizo-affective' at present. Ten patients (4.5% of admissions and 8% of psychotic admissions within the age group studied) satisfied 3 definitions, a figure which demonstrates the numerical importance of this group of unclassified mental disorders.
在首次收治的精神病患者样本中，对精神分裂情感性精神病的八种定义进行了比较。它们之间的一致性非常低（平均为0.19），这表明目前对于“精神分裂情感性”这一术语的含义存在很大分歧。十名患者（在所研究年龄组中占入院患者的4.5%，占精神病入院患者的8%）符合三种定义，这一数字表明了这组未分类精神障碍在数量上的重要性。
