101958: Genetic and environmental influences on thin-ideal internalization

Volume 45 Issue 8

About the Course:

Current research on the etiology of thin-ideal internalization focuses on psychosocial influences (e.g., media exposure). The possibility that genetic influences also account for variance in thin-ideal internalization has never been directly examined. This study used a twin design to estimate genetic effects on thin-ideal internalization and examine if environmental influences are primarily shared or non-shared in origin.
