ABNORMAL BEHAVIOR I
Definitions of Abnormal Behavior
3. A Sense of Personal Discomfort Seen As Abnormality

·
Discomfort can be in the form of anxiety, distress, or guilt.
4. Inability to function effectively
·
People, who cannot function and perform as effectively as they ought to, are seen as abnormal.

This definition includes adjusting, and adapting to the social requirements.
5. The Legal Definition of Abnormality
·  Laws in different countries define abnormality according to their legal standards.
·  It is primarily needed for differentiating sanity from insanity.
·  Abnormality may be viewed as not being able to foresee and understand the consequences of
the criminal act.
·
Or it can be taken as inability to control one's own thoughts and behaviors.
·
Or it can be the ability to see right as different from wrong.
Perspectives on Abnormality
·
Approaches to studying, describing, understanding, explaining, and predicting abnormality.
·
These approaches affect the way a mental patient will be treated.
1. Medical Perspective
·
Psychological problems are caused by physiological factors.
·
These can be the biological processes and systems, genetic factors, the nervous system and the
neurotransmitters, hormonal changes, or external variables affecting the biology of a person.
2. Psychodynamic Perspective

Childhood experiences are the root cause of mental disorders.
·
Unconscious determinants are significant.
3. Behavioral Perspective

Abnormality is a learned response.
·
It results from our interaction with the external world.
4. Cognitive Perspective

in abnormality behavior.
6. Sociocultural Perspective

Classification of Mental Disorders
·
Kraepelin gave the first classification system of mental disorders.
·
A number of classification systems followed afterwards.
·
The purpose was to assist the clinicians diagnose mental disorders, as well as to determine the
extent of the problem.
Classification Systems
·
DSM- IV- TR
·
ICD
DSM-IV-TR
·
Diagnostic and statistical manual of mental disorders is the classification system compiled by
the American Psychiatric Association.
·
This is the most widely used classification system all over the world.
ICD: International Classification
·
For decades, mental health professionals in Western Europe and a major part of the world used
this classification system.
·
The World Health Organization developed ICD.
·
ICD is a comprehensive classification system of all kinds of diseases, including psychological or psychiatric illnesses.
·
For a number of years ICD9 remained a popular diagnostic system.
·
Research, in the last more than a decade, reflected that the revised and improved versions of
DSM had an edge over ICD in many respects.
·
Besides, there were no major differences as such in the two systems.
·
Also, the need for a single universally accepted system was intensely felt.
·
Therefore today DSM-IV-TR is recognized as a universally accepted diagnostic system.
DSM-IV-TR
·
The first DSM was published in 1917.
·
It originated from a project of the American Medico-Psychological Association, now known as
American psychiatric Association and United States Bureau of the Census.
·
In order to collect uniform data on hospitalized mental patients, they developed a list of 59
mental illnesses.
·
The list was further expanded with the publication of the first DSM in 1952.
·
The first DSM included a list of 106 mental illnesses.
·
DSM-II was published in 1968.
·
DSM-III was published in 1980.
·
DSM-III-R was published in 1987.

DSM-IV-TR was published in 2000.
DSM-IV-TR contains definitions of more than 200 mental disorders.
These disorders are organized into 17 major categories.
Multi Axial System of DSM-IV-TR

the diagnosis of a patient.
Axes of DSM-IV-TR
·  Axis I: Clinical disorders
·  Axis II: Long standing problems that are frequently overlooked in the presence of disorders
listed in axis mental retardation, personality disorder, and I.
·
Axis III: General medical conditions that may be relevant to a psychological disorder.
·
Axis IV: Psychosocial or environmental problems that a person is facing.
