The aim of the current study was to evaluate the utility of maternal recall for obtaining history of obstetric complications (OCs) in psychiatric research.
Obstetric information from in-depth structured maternal interviews and from hospital birth records was compared in 45 mothers of schizophrenic patients and 34 control mothers. Both types of information were blindly and independently scored for OCs using the McNeil-Sjöström OC Scale.
Considerable discrepancies were observed between interviews and records, irrespective of maternal group. No significant differences were found between patient and control mothers in error type (omission, commission, total retrospective error) or recall facility for selected events. More errors of commission were made by mothers of patients with negative family history than mothers of patients with positive family history for psychiatric disorder. Patients had significantly more OCs than controls only when hospital record information was utilized.
OC history obtained by maternal recall has methodological limitations.
本研究的目的是评估在精神病学研究中，通过母亲回忆获取产科并发症（OCs）病史的效用。
对45名精神分裂症患者的母亲和34名对照母亲，比较了深入结构化母亲访谈和医院出生记录中的产科信息。使用麦克尼尔 - 舍斯特罗姆OC量表，对这两种类型的信息进行盲法独立评分以评估OCs。
无论母亲所属组别如何，访谈和记录之间均观察到显著差异。患者母亲和对照母亲在错误类型（遗漏、误报、总回顾性错误）或选定事件的回忆能力方面未发现显著差异。精神病家族史阴性患者的母亲比家族史阳性患者的母亲出现更多误报错误。仅当使用医院记录信息时，患者的OCs才显著多于对照。
通过母亲回忆获得的OC病史存在方法学上的局限性。
