615 neurotic patients from two outpatient Clinics were divided into three groups: only children, siblings with minimal age difference group, siblings not of minimal age difference group. The following hypothesis were to be examined: The younger of two siblings with minimal age difference are at greater risk to develop schizoid disorders. The hypothesis was proved correct. Amongst our patients the younger of two siblings of minimal age difference were at a particularly high risk in becoming schizoid. In addition we found the following risiko configuration in the early developmental period. Frequently these patients originated from families with many children, the age difference to the next sibling is also minimal, the mother is frequently lost before the age of three and the father is often self employed. These results confirm the so called "hypothesis of neglect" as it is observed in the development of schizoid disorders. A reexamination of the result of this research is to be desired.
来自两家门诊诊所的615名神经症患者被分为三组：独生子女组、年龄差最小的兄弟姐妹组、年龄差并非最小的兄弟姐妹组。以下假设有待检验：年龄差最小的两个兄弟姐妹中较年幼的一方患精神分裂样障碍的风险更高。该假设被证明是正确的。在我们的患者中，年龄差最小的两个兄弟姐妹中较年幼的一方患精神分裂样障碍的风险尤其高。此外，我们在早期发育阶段发现了以下风险模式。这些患者通常来自多子女家庭，与下一个兄弟姐妹的年龄差也最小，母亲经常在三岁前离世，父亲往往是个体经营者。这些结果证实了在精神分裂样障碍发展过程中观察到的所谓“忽视假说”。希望对这项研究的结果进行重新审视。
