This study examined the familial aggregation of spelling disability in a sample of 32 German school-aged children and their relatives. The influence of two different diagnostic criteria (low-achievement criterion, and regression-based IQ-discrepancy criterion) on the rate of affectedness was investigated. Results revealed that 52.3-61.9% of the sibs and 26-34% of the parents were spelling disabled. Little evidence was found for an influence of the diagnostic criterion on the rate of affectedness.
本研究在32名德国学龄儿童及其亲属样本中,对拼写障碍的家族聚集性进行了调查。研究了两种不同诊断标准(低成就标准和基于回归的智商差异标准)对患病比例的影响。结果显示,52.3% - 61.9%的同胞和26% - 34%的父母存在拼写障碍。几乎没有证据表明诊断标准对患病比例有影响。
