Classifying System
DSM-IV – (1994)

system in the United States
• Common terminology across disciplines
• Etiology –
The causes of, or factors related to, the
development of a disorder
Explosion of Mental Disorders
•
•
Supporters of new
categories answer that
is important to
distinguish disorders
precisely.
Critics point to an
economic reason:
diagnoses are needed
for insurance reasons
so therapists will be
compensated.
Problems with DSM-IV
• Danger of overdiagnosis
• Power of labels (self-fulfilling prophecy)
• Confusion of serious disorders with
normal problems
• Illusion of objectivity and universality
What are the Consequences
of Labeling People?

problem (Rosenhan Study**)

VII. Drug Abuse and Addiction
• Biology and addiction.
– a person’s biochemistry,
– metabolism, and
– genetic predisposition
Learning, Culture, and Addiction
• Addiction patterns vary according to cultural
practices and the social environment.
• Policies of total abstinence tend to increase
addiction rates rather than reduce them.
• Not all addicts have withdrawal symptoms
when they stop taking a drug.
• Addiction does not depend on the properties
of the drug alone, but also on the reason for
taking it.
Failure of the Addiction Prediction
•
•
•
•
75% of US Soldiers who
tested “drug positive” in
reported being addicted
during their tour.
Fewer reported postVietnam drug use (blue
bar).
Even fewer still showed
dependency(green bar).
This contradicts what the
biomedical model of
addiction would predict.**
Debating the Causes of Addiction
• Problems with drugs are more likely when:
– A person has a physiological vulnerability to a
drug.
– A person believes she or he has no control over
the drug.
– Laws or customs encourage people to take the
drug in binges, and moderate use is neither
tolerated nor taught.
– A person comes to rely on a drug as a method
of coping with problems, suppressing anger or
fear, or relieving pain.
– Peer group uses drugs or drinks heavily, forcing
the person to choose between using drugs or
losing friends.
