Psychological DisordersAn Introduction

Psychological Disorder

• A “harmful dysfunction” in which behavior is judged to be atypical, disturbing, maladaptive and unjustifiable.

What is abnormal, disturbing maladaptive and unjustifiable depends on:

•Culture

•Environmental Conditions

•Individual Person

•Time Period

Defining Psychological Disorders

Mental health workers view psychological disorders as persistently harmful thoughts, feelings, and actions.

When behavior is deviant, distressful, and dysfunctional psychiatrists and

psychologists label it as disordered (Comer, 2004).

The 3 D’s

Deviant, Distressful & Dysfunctional

1.Deviant behavior (going naked) in one culture may be considered normal, while in others it may lead to arrest.

2.Deviant behavior must accompany distress.

3. If a behavior is dysfunctional it is clearly a disorder.

In the Wodaabe tribe men wear costumes to

attract women. In Western society this would be considered

abnormal.

Early Theories

• Afflicted people were possessed by evil spirits.

Understanding Psychological Disorders

Ancient Treatments of psychological disorders include trephination, exorcism, being caged

like animals, being beaten, burned, castrated, mutilated, or transfused with animal’s blood.

Trephination (boring holes in the skull to remove evil forces)

Early Theories

• Music or singing was often used to chase away spirits.

•In some cases trephening was used:

Cutting a hole in the head of the afflicted to let out the evil spirit.

Trephening

Early Theories• Another theory was to make the body

extremely uncomfortable.

History of Mental Disorders

• In the 1800’s, disturbed people were no longer thought of as madmen, but as mentally ill.

Did this mean better treatment?

They were first put in hospitals.

Early Mental Hospitals• They were nothing more than barbaric

prisons.

•The patients were chained and locked away.

•Some hospitals even charged admission for the public to see the “crazies”, just like a zoo.

Philippe Pinel

• French doctor who was the first to take the chains off and declare that these people are sick and “a cure must be found!!!”

Somatogenic

• At this time- it was believed that mental illness had a bodily cause- Somatogenic.

But Somatogenic could not explain disorders such as hysteria (now called conversion disorder).

Many disorders are psychogenic: the origin is psychological, not physical.

Medical Model

When physicians discovered that syphilis led to mental disorders, they started using medical models

to review the physical causes of these disorders.

1. Etiology: Cause and development of the disorder.

2. Diagnosis: Identifying (symptoms) and distinguishing one disease from another.

3. Treatment: Treating a disorder in a psychiatric hospital.

4. Prognosis: Forecast about the disorder.

Current Perspectives

• Medical Perspective: psychological disorders are sicknesses and can be diagnosed, treated and cured.

Current Perspectives

• Bio-Psycho-Social Perspective: assumes biological, psychological and sociocultural factors combine to interact causing psychological disorders.

Used to be called Diathesis-Stress Model: diathesis meaning predisposition and stress meaning environment.

Classifying Psychological Disorders

The American Psychiatric Association rendered a Diagnostic and Statistical Manual of Mental Disorders (DSM) to

describe psychological disorders.

The most recent edition, DSM-IV-TR (Text Revision, 2000), describes 400

psychological disorders compared to 60 in the 1950s.

Classifying Psychological Disorders

• DSM-IV: Diagnostic Statistical Manual of Mental Disorders: the big book of disorders.

Two Major Classifications:

Neurotic Disorders

• Distressing but one can still function in society and act rationally

Psychotic Disorders•Person loses contact with reality, experiences distorted perceptions

Multiaxial Classification

Are Psychosocial or Environmental Problems (school or housing issues) also present?

Axis IV

What is the Global Assessment of the person’s functioning?Axis V

Is a General Medical Condition (diabetes, hypertension or arthritis etc) also present?

Axis III

Is a Personality Disorder or Mental Retardation present?

Axis II

Is a Clinical Syndrome (cognitive, anxiety, mood disorders [16 syndromes]) present?

Axis I

Multiaxial Classification

Note 16 syndromes in Axis I

Multiaxial Classification

Note Global Assessment for Axis V

Goals of DSM

1. Describe (400) disorders.2. Determine how prevalent the

disorder is.

Disorders outlined by DSM-IV are reliable. Therefore, diagnoses by different professionals are similar.

Others criticize DSM-IV for “putting any kind of behavior within the compass of psychiatry.”

Labeling Psychological Disorders

1. Critics of the DSM-IV argue that labels may stigmatize individuals.

2. Rosenthal-Being sane in insane places

Labeling Psychological Disorders

2. Labels may be helpful for healthcare professionals when communicating with one another and establishing therapy.

memory of specific events that took place, usually traumatic. The loss of memory is localized with a specific window of time. For example, a survivor of a car wreck who has no memory of the experience until two days later is experiencing localized amnesia.

• Selective amnesia happens when a person can recall only small parts of events that took place in a defined period of time. For example, an abuse victim may recall only some parts of the series of events around the abuse.

• Generalized amnesia is diagnosed when a person's amnesia encompasses his or her entire life.
