A special thanks to my former student teacher--Ms. Sharon Mohr--for her diligent
research, insightful professional expertise, and valuable thoughtful effort in
compiling much of the information included in this overview of
Psychological Disorders.
Defining Abnormality
Difficult to define…
3 Criteria…
Deviance
 Distress
 Disability/Maladaptive Behavior

Symptom/Behavior Continuum:
_----_________________
Abnormal

Abnormal
Ancient Perspective
Perceived Causes
 movements
 lunacy-
 evil
of sun or moon
full moon
spirits
Ancient Treatments
 exorcism,
caged like animals, beaten, burned,
mutilated, blood replaced with animal’s blood
Bio-psycho-social Model
Biological
(chemistry, brain)
Sociocultural
(Societal expectations,
definition of normality
and disorder)
Psychological
( learned helplessness,
negative perceptions
and memories)
assumes that
biological,
sociocultural, and
psychological
factors combine
and interact to
produce
psychological
disorders
Medical Model
Diagnosis
 Label
for a set of symptoms
Prognosis
 Prediction
or forecast for the course of a
D/O
Etiology
 Suspected
cause of a disorder
Classifying Disorders
DSM-IV-TR
Diagnostic and Statistical Manual of Mental
Disorders, 4th edition, Text Revision
 Published by the American Psychiatric Association
 2000…(most recent update 2004)
 Next major revision (DSM-V) anticipated for 2011.

Provides for reliable classification and description
of all mental illnesses
Allows for better communication
DSM’s Multi-axial Diagnosis
Axis I Major Clinical Disorders
Axis II Mental Retardation & Personality Disorders
Axis III General Medical Conditions
Axis IV Psychosocial/Environmental
Stressors
Axis V Global Assessment of Functioning
# between 1 and 100
 Current and Highest in past year

Labeling Issues
Reasons to Label/Diagnose:
Needed for communication
 Guide treatment
 Insurance reimbursement

Arguments against Labeling:
Creates a stigma
 Creates a self-fulfilling prophecy
 Fail to see the person behind the disorder

TYPES OF PSYCHOTHERAPY — A number
of types of psychotherapy are used to treat
psychological disorders:
•Cognitive therapy identifies habitual ways
in which patients distort information (e.g.
automatic thoughts) and teaches patients to
identify, evaluate, and respond to their
dysfunctional thoughts and beliefs, using a
variety of techniques to change thinking,
mood, and behavior. Cognitive therapy is a
structured, goal oriented, problem focused,
and time limited intervention.
TYPES OF PSYCHOTHERAPY
•Behavioral therapy attempts to alter
behavior by systematically changing the
environment that produces the behavior.
Behavioral changes are believed to lead to
changes in thoughts and emotions.
•Exposure-based behavioral treatments
utilize gradual, systematic, repeated
exposure to the feared object or situation to
allow patients with anxiety disorders to
become desensitized to the feared stimulus.
TYPES OF PSYCHOTHERAPY
•Cognitive Behavioral therapy (CBT)
combines principles of both behavioral and
cognitive therapy, focusing simultaneously on
the environment, behavior, and cognition.
Cognitive behavioral therapy is also
structured, goal directed, problem focused.
Patients learn how their thoughts contribute
to symptoms of their disorder and how to
change these thoughts. Increased cognitive
awareness is combined with specific
behavioral techniques.
TYPES OF PSYCHOTHERAPY
•Problem Solving therapy, a short-term,
cognitive behavioral intervention, teaches a
systematic method for solving current and
future problems. Patients acquire new skills
for successfully resolving interpersonal
difficulties. These skills include the following
sequential steps: 1) Problem definition; 2)
Goal setting; 3) Generating, choosing, and
implementing solutions; and 4) Evaluating
outcomes.
TYPES OF PSYCHOTHERAPY
•Interpersonal therapy addresses issues
such as grief, role transitions, interpersonal
role disputes, and interpersonal deficits as
they relate to the patient's current
symptoms.
•Family therapy attempts to correct
distorted communications and relationships
as a means of helping the entire family,
including the identified patient. In patients
with serious mental illness, such as
schizophrenia, family therapy helps family
members learn about the disorder, solve
problems, and cope more constructively with
the patient's illness.
TYPES OF PSYCHOTHERAPY
•Psychoeducation provides patients with
information about their diagnosis, its treatment, how
to recognize signs of relapse, relapse prevention, and
strategies to cope with the reality of prolonged
emotional or behavioral difficulties.
•The goal of psychoeducation is to reduce distress,
confusion, and anxiety within the patient and/or the
patient's family to facilitate treatment compliance and
reduce the risk of relapse.
•Psychoeducation is often particularly helpful for
patients and the families of patients with chronic,
severe psychiatric disorders such as schizophrenia and
bipolar disorder.
