Description

The Familial Control Method is defined as "Using a measure of the same trait in the parent as the child as a covariate in models estimating the effect of the rearing environment"; the covariate "serves as a proxy control for the genetic transmission effect". The authors advise assessing the trait in both parents, because the child shares all their genes with both parents but only 50% with one. It is designed for traits transmitted mostly through genes, like reading ability, and is currently the most feasible proxy genetic control for most behavioral researchers, requiring neither twin/adoption samples nor DNA.
