States there is a difference in genetic predisposition to drugs and alcohol between children of alcohol-dependent parents and those of non-dependent parents?

• A. Etiology of substance related disorders
• B. Sociocultural view of etiology
• C. Behavioral view of etiology
• D. Biological view of etiology

Answer: (D)

Genetic predisposition to substance use disorders explains why children of alcohol-dependent parents have higher risk than those of non-dependent parents. This is the biological view of etiology, which focuses on inherited genetic and neurobiological factors that influence susceptibility to alcohol and drug problems. Family studies show a higher risk among relatives, and twin and adoption research points to heritability and biological pathways involving brain reward systems, metabolism, and related processes. While environment and learning play roles, the key point here is that inherited biology helps explain the difference in risk between these groups.
