In order to examine the hypothesis that being a firstborn or only child is specifically associated with obsessive-compulsive disorder, the birth order positions and sibship sizes of 62 patients with obsessive-compulsive disorder were compared with those of 60 agoraphobic and 92 depressed patients. No significant group differences were found for men, women, or both sexes combined. Results conflict with earlier findings which supported the hypothesized relationship between birth order status and development of obsessive-compulsive patterns in men. In addition to possible differences in methodology, discrepancies between the present findings and those of earlier studies may reflect a decline over the past 20 years in the percentage of male obsessive compulsives that were either firstborn or only children.
为了检验长子或独生子女与强迫症存在特定关联这一假设，将62名强迫症患者的出生顺序位置和家庭规模与60名广场恐惧症患者及92名抑郁症患者的进行了比较。在男性、女性或男女合计方面均未发现显著的组间差异。研究结果与早期支持出生顺序状态与男性强迫症模式发展之间假设关系的研究结果相冲突。除了方法上可能存在的差异外，当前研究结果与早期研究结果之间的差异可能反映出在过去20年中，身为长子或独生子女的男性强迫症患者的比例有所下降。
