Chapter 11: Substance-Related and Impulse-Control Disorders
Perspectives on Substance-Related
Disorders: An Overview (cont.)
Five Main Categories of Substances
Depressants – Result in behavioral sedation
Stimulants – Increase alertness and elevate mood
Opiates – Primarily produce analgesia and
euphoria
Hallucinogens – Alter sensory perception
Other drugs of abuse – Include inhalants, anabolic
steroids, medications
Abnormal Psychology: An Integrative Approach, 4th Edition, David H. Barlow, V. Mark Durand
Chapter 11: Substance-Related and Impulse-Control Disorders
The Depressants: Alcohol Use Disorders
Psychological and Physiological Effects of Alcohol
Central Nervous system depressant
Affects several neurotransmitter systems
Specific target is GABA
Effects of Chronic Alcohol Use
Alcohol intoxication & withdrawal
Associated conditions – Dementia & Wernicke’s
disease
Fetal alcohol syndrome
DSM-IV-TR Criteria for Disordered Alcohol Use
Abnormal Psychology: An Integrative Approach, 4th Edition, David H. Barlow, V. Mark Durand
Chapter 11: Substance-Related and Impulse-Control Disorders
Alcohol: Some Facts and Statistics
In the United States
Most adults view themselves light drinkers or
abstainers
Over 50% of the U.S. (> 12 years age) report
current use
15 million Americans are alcohol dependent
Rates are highest among Caucasian & Native
Americans
Males use and abuse alcohol more than females
Violence is associated with alcohol
Alcohol alone does not cause aggression
Abnormal Psychology: An Integrative Approach, 4th Edition, David H. Barlow, V. Mark Durand
Chapter 11: Substance-Related and Impulse-Control Disorders
Sedative, Hypnotic, or Anxiolytic
Substance use Disorders: An Overview
The Nature of Drugs in This Class
Sedatives – Calming (e.g., barbiturates)
Hypnotic – Sleep inducing
Anxiolytic – Anxiety reducing (e.g.,
benzodiazepines)
Effects Are Similar to Large Doses of Alcohol
Combining such drugs with alcohol is synergistic
All Influence the GABA Neurotransmitter System
DSM-IV-TR Criteria for this Class of Disorders
Main criteria and distinguishing features
Abnormal Psychology: An Integrative Approach, 4th Edition, David H. Barlow, V. Mark Durand
Chapter 11: Substance-Related and Impulse-Control Disorders
Stimulants: An Overview

Produce elation, vigor, reduce fatigue
Effects are followed by extreme fatigue and depression
DSM-IV-TR Criteria for Amphetamine Intoxication
Ecstasy and Ice
Produces effects similar to speed, but no “comedown”
2% of college students report using Ecstasy
Both drugs can result in dependence
Amphetamines stimulate CNS by
Enhancing release of norepinephrine and dopamine
Reuptake is subsequently blocked

Chapter 11: Substance-Related and Impulse-Control Disorders
Causes of Substance-Related Disorders:
Family and Genetic Influences
Results of Family, Twin, and Adoption Studies
Substance abuse has a genetic component
Much of the focus has been on alcoholism
Genetic differences in alcohol metabolism
Multiple genes are involved in substance abuse
Abnormal Psychology: An Integrative Approach, 4th Edition, David H. Barlow, V. Mark Durand
Chapter 11: Substance-Related and Impulse-Control Disorders
Causes of Substance-Related Disorders:
Neurobiological Influences
Results of Neurobiological Research
Drugs affect the pleasure or reward centers in the
brain
The pleasure center – Dopamine, midbrain, frontal
cortex
GABA turns off reward-pleasure system
Inhibition of neurotransmitters for anxiety /
negative affect
Abnormal Psychology: An Integrative Approach, 4th Edition, David H. Barlow, V. Mark Durand
Chapter 11: Substance-Related and Impulse-Control Disorders
Causes of Substance-Related Disorders:
Psychological Dimensions
Role of Positive and Negative Reinforcement
The self-medication and the tension reduction
hypotheses
Substance abuse as a means to cope with
negative affect
Opponent-Process Theory
Why the crash after drug use fails to stop drug use
Role of Expectancy Effects
Expectancies influence drug use and relapse
Abnormal Psychology: An Integrative Approach, 4th Edition, David H. Barlow, V. Mark Durand
Chapter 11: Substance-Related and Impulse-Control Disorders
Causes of Substance-Related Disorders:
Social and Cultural Dimensions
Exposure to Drugs is a Prerequisite for Use of Drugs
Media, family, peers
Parents and the family appear critical
Societal Views About Drug Abuse
Sign of moral weakness – Failure of self-control
Sign of a disease – Caused by underlying processes
The Role of Cultural Factors
Influence the manifestation of substance abuse
Abnormal Psychology: An Integrative Approach, 4th Edition, David H. Barlow, V. Mark Durand
Chapter 11: Substance-Related and Impulse-Control Disorders
An Integrative Model of Substance-Related Disorders
Exposure or Access to a Drug
Is necessary, but not sufficient for abuse and
addiction
Drug Use Depends on Social and Cultural
Expectations
Drugs Are Used Because of their Pleasurable Effects
Drugs Are Abused for Reasons that are More
Complex
The premise of equifinality
Stress may interact with psychological, genetic,
social, and learning factors

effects
Examples include naltrexone for opiate and
alcohol problems
Abnormal Psychology: An Integrative Approach, 4th Edition, David H. Barlow, V. Mark Durand
Chapter 11: Substance-Related and Impulse-Control Disorders
Biological Treatment of
Substance-Related Disorders (cont.)
