Surgery and electroshock.

The Question of Drugs
©2002 Prentice Hall
Antipsychotic Drugs



Many block or reduce sensitivity of brain
receptors that respond to dopamine.
Some increase levels of serotonin, a
neurotransmitter that inhibits dopamine
activity.
Can relieve positive symptoms of
schizophrenia but are ineffective for or
even worsen negative symptoms.

Antidepressant Drugs

Monoamine oxidase inhibitors (MAOIs)


Tricyclic antidepressants


Elevate norepinephrine and serotonin in brain by
blocking an enzyme that deactivates these
neurotransmitters.
Boost norepinephrine and serotonin in brain by
preventing normal reuptake of these substances.
Selective serotonin reuptake inhibitors

work same way as tricyclic antidepressants but target
serotonin.

Tranquilizers


Increase the activity of the neurotransmitter
gamma-aminobutyric acid (GABA).
Developed for treatment of mild anxiety
and often overprescribed by general
physicians for patients who complain of
any mood disorder.

Lithium Carbonate




Used to treat bipolar disorder.
Moderates levels of norepinephrine or by
protecting cells from being overstimulated
by the neurotransmitter, glutamate.
Must be given in right dose and
bloodstream levels need to be monitored.
Newer drug treatments for bipolar disorder
include Tegetrol and Depakote.

Cautions About Drug Treatment




Placebo effect
High Relapse and dropout rates.
Dosage problems.
Long-term risks
©2002 Prentice Hall
Placebo effect


The apparent success of a treatment that is
due to the patient’s expectation of hopes
rather than to the drug or treatment itself.
Meta-analyses indicates that clinicians
considered medication helpful yet patient
ratings in treatment groups were no greater
than patient ratings in placebo groups.
©2002 Prentice Hall
High Relapse and Dropout Rate


There may be short term success but many
patients (50% to 66%) stop taking
medication due to side effects.
Individuals who take antidepressants
without learning to cope with problems are
more likely to relapse.
©2002 Prentice Hall
Dosage Problems


Finding the therapeutic window or the
amount of medication that is enough but
not too much.
Drugs may be metabolized differently in:


men and women, old and young, and in
different ethnic groups.
Groups may differ in dosages due to
variations in metabolic rates, amount of body
fat, number or type of drug receptors in the
brain, smoking and eating habits.

Long term risks

Antipsychotic drugs can be dangerous,
even fatal if taken for many years.


Tardive dyskinesia
Antidepressants are assumed to be same
but no long term studies have been
conducted.

Surgery and Electroshock

Psychosurgery


Any surgical procedure that destroys selected
areas of the brain believed to be involved in
emotional disorders or violent, impulsive
behavior.
Electroconvulsive Therapy (ECT)

A procedure used in cases of prolonged and
severe major depression, in which a brief
brain seizure is induced.

Kinds of Psychotherapy




Psychodynamic therapy.
Behavioral and Cognitive therapy.
Humanist and Existential therapy.
Family therapy.
©2002 Prentice Hall
Psychodynamic Therapy

Goal is exploring the unconscious

Free Association


In psychoanalysis, a method of uncovering
unconscious conflicts by saying freely whatever
comes to mind.
Transference

In psychodynamic therapies, a critical step in which
the client transfers unconscious emotions or
reactions, such as conflicts about his or her parents,
onto the therapist.

Behavior and Cognitive Therapy

Behavior therapy






Systematic desensitization.
Aversive conditioning.
Exposure treatments.
Behavioral records and contracts.
Skills training.
Cognitive therapy
©2002 Prentice Hall
Behavior Therapy

A form therapy that applies principles and
techniques of classical and operant
conditioning to help people change self
defeating or problematic behaviors.
©2002 Prentice Hall
Systematic Desensitization


A step by step process of desensitizing a
client to a feared object or experience,
Based on counterconditioning.
©2002 Prentice Hall
Exposure (Flooding)

A technique whereby a person suffering
from an anxiety disorder such as a phobia
or panic attack, is taken directly into the
feared situation until the anxiety subsides.
©2002 Prentice Hall
Behavioral Records

A method of keeping careful data on the
frequency and consequences of the
behavior to be changed.
©2002 Prentice Hall
Skills Training

An effort to teach a client skills he or she
may lack as well as new more constructive
behaviors to replace self-defeating ones.
©2002 Prentice Hall
Cognitive Techniques



Examine the evidence for beliefs.
Consider other explanations for the
behavior of others.
Identify assumptions and biases.
©2002 Prentice Hall
Humanist Therapy

Humanist therapy



Based on the assumption that people seek selfactualization and self-fulfillment.
Emphasized people’s free will to change, not past
conflicts.
Client-Centered (Nondirective) Therapy

Developed by Carl Rogers and emphasizes the
therapist’s empathy with the client, seeing the
world as client does, and creating climate of
Unconditional Positive Regard.

Helps clients explore the meaning of existence
and face with courage the great issues of life such
as death, freedom, free will, alienation and
loneliness.

Family and Couples Therapy



Problems develop in the context of family, are
sustained by the dynamics of the family and that any
changes made will affect all members of the family.
Can look for patterns of behavior across generations
and create a family tree of psychologically
significant events.
Family-System Perspective
 Therapy with individuals or families that focuses
on how each member forms part of a larger
interacting system.

©2002 Prentice Hall
problems.
Evaluating Psychotherapy




The scientist-practitioner gap.
When therapy helps.
Which therapy for which problem?
When therapy harms.
©2002 Prentice Hall
The Scientist-Practitioner Gap



Some psychotherapists believe that
evaluating therapy using research methods
is futile.
Scientists find that therapists who do not
keep up with empirical findings are less
effective and can do harm to clients.
Economic pressures require empirical
assessment of therapies.
©2002 Prentice Hall
Is More Psychotherapy Better?


With additional therapy
sessions, the percentage
of people improved
increased up to 26
sessions.
Rate of improvement
then levels off


Based on a summary of
15 studies, 2400 clients
(Howard, et al., 1996).
Patients’ sense of
improvement slower but
more steady.

Psychotherapy Research Questions



What are the common ingredients in
successful therapies?
What kinds of therapy are best suited for
which problems?
Under what conditions can therapy be
harmful?
©2002 Prentice Hall
Common Ingredients in Successful
Therapies



When there is a bond between therapist and
client (a.k.a. Therapeutic Alliance).

When therapists distinguish normal cultural
patterns from individual psychological
problems.

Which Therapy for Which Problem?

Health Problems



method of therapy.
Qualities of client and therapist, and their alliance,
also determine success.

When Therapy Harms




Sexual intimacies, or other unethical
