Chapter 17 Biological Theories Genetic Factors – Family history, adoption, and twin studies all suggest that genetics may play a substantial role in at least some forms of addiction. Alcohol Reactivity – The sons of alcoholics have a lower reactivity to moderate doses of alcohol which may lead them to drink substantially more before they begin to feel drunk.

Chapter 17 Behavioral and Cognitive Theories Children and adolescents learn alcohol-related behaviors from the modeling of their parents and important others in their culture. People who expect alcohol to reduce their distress and who do not have other, more adaptive means of coping available to them are more likely than others to drink alcohol when they are upset and are more likely to have social problems related to drinking.

Chapter 17 Sociocultural Approaches Chronic stress combined with an environment that supports and even promotes the use of substances as an escape is a recipe for widespread substance abuse and dependence. Substance use, particularly alcohol use, is much more acceptable for men than for women in many societies. When women do become substance abusers, their patterns of use and reasons for use tend to differ from men’s.
