Physical similarity and the equal-environment assumption in twin studies of psychiatric disorders.

Behavior genetics - 1 Jul 1995

Hettema J M, Neale M C, Kendler K S

Abstract excerpt

The equal-environment assumption (EEA), upon which twin methodology is based, was examined for the impact of physical similarity on phenotypic resemblance in five common psychiatric disorders: major depression, generalized anxiety disorder, phobia, alcoholism, and bulimia. A population-based sample of 882 female-female twin pairs of known zygosity was rated for similarity of appearance by color photographs....
