Self-reported reading ability of the parents of 174 reading-disabled children and of 182 controls was used to estimate the posterior probability that a child will become reading disabled given that a parent is affected. Using Bayesian inverse probability analysis, it was found that the risk for reading disability is increased substantially (by a factor of from about 4 to over 13) if either parent has had difficulty in learning to read. The absolute risk appears to be sufficiently high to warrant clinical application of family history information as one component of a multifactorial risk assessment battery.
