Interobserver variation in diagnosis is thought to be an important source of bias in studies of cerebral palsy. Kappa (kappa) statistics were used as a measure of interobserver diagnostic agreement for two case series of 20 children attending an institution for the motor handicapped. kappa increased threefold after standardisation of diagnostic terms. Sources of diagnostic variation are discussed and possibilities and benefits of its further reduction explored.
在脑瘫研究中，观察者间诊断差异被认为是偏差的一个重要来源。对于两个包含20名就读于一所运动障碍机构儿童的病例系列，kappa统计量被用作衡量观察者间诊断一致性的指标。在诊断术语标准化后，kappa值增加了两倍。文中讨论了诊断差异的来源，并探讨了进一步减少差异的可能性和益处。
