Abstract
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.Keywords
