Final answer:
The model of eating disorders within the internalizing/externalizing framework that fits best is a combination of internal emotional vulnerabilities and external behavioral factors.
Step-by-step explanation:
Within the internalizing/externalizing framework, the model of eating disorders that fits best, based on the findings from For bush et al. (2010), is a complex one that involves both internalizing and externalizing factors. The study suggests that eating disorders are influenced by a combination of genetic factors, such as temperament and personality traits, and environmental factors, including social and cultural influences. This model recognizes that individuals with eating disorders may have both internal emotional vulnerabilities and external behavioral factors influencing their disorder.
