CHAPTER 17: THE NATURE AND CAUSES OF PSYCHOLOGICAL
DISORDERS
Etiology the causes or origins of a disorder.
Classification and Diagnosis of Psychological Disorders
What is Abnormal?
The term abnormal literally refers to any departure from the norm. Thus a
short or tall person is abnormal and so is someone who is especially
intelligent.
The tern abnormal has taken on a pejorative connotation: we use it to refer to
characteristics we dislike or fear.
Psychologists stress that the most important feature of a psychological
disorder is not whether a persons behaviour is abnormal different from that
of most other people but whether it is maladaptive.
Psychological disorders cause distress or discomfort and interfere with
peoples ability to lead satisfying, productive lives. They often make it
impossible for people to hold jobs, raise families, or relate to others socially.
Perspectives on the Causes of Psychological Disorders
In general, they are caused by the interaction of hereditary, cognitive, and
environmental factors.
Different psychologists and other mental health professionals approach the
study of psychological disorders from different perspectives, each of which places
www.notesolution.com
more or less emphasis on these factors.
The Psychodynamic Perspective:
According to the psychodynamic perspective, which is based on Freuds early
work, psychological disorders originate in intrapsychic conflict produced by the 3
components of the mind: the id, ego, and superego.
These conflicts may centre on attempts to control potentially harmful
expressions of sexual or aggressive impulses, or they may also arise from
attempts to cope with external dangers and traumatic experiences. For some
people, the conflict becomes so severe that the minds defence mechanisms
cannot produce a resolution that is adequate for mental health. The result is
that the defence mechanisms themselves distort reality or the individual begins
to function in some areas of life in a manner characteristic of an earlier
developmental stage.
The Medical Perspective:
The origins of the medical perspective lie in the work of the ancient Greek
physician Hippocrates.
Hippocrates formulated the idea that excesses of the four humours (black
bile, yellow bile, blood, and phlegm) led to emotional problems. Other
physicians, Greek and Roman alike, extended Hippocrates ideas and developed
the concept of mental illness illnesses of the mind.
The medical model is based on the idea that psychological disorders are
caused by specific abnormalities of the brain and nervous systems and that, in
principle; they should be approached for treatment in the same way as physical
illnesses.

The Cognitive-Behavioural Perspective:
The cognitive-behavioural perspective holds that psychological disorders are
learned maladaptive behaviour patterns that can best be understood by focusing
on environmental factors and a persons perception of those factors.
A psychological disorder is caused by the persons interaction with his or her
environment.
According to the cognitive-behavioural perspective, it is not merely the
environment that matters what also counts is a persons ongoing subjective
interpretation of the events taking place in his or her environment.
Therapists operating from the cognitive-behavioural perspective therefore
encourage their clients to replace or substitute maladaptive thoughts and
behaviours with more adaptive ones.
The Humanistic Perspective:
According to this view, psychological disorders arise when people perceive
that they must earn the positive regard of others. Thus, they become overly
sensitive to the demands and criticisms of others and come to define their
personal value primarily in terms of others’ reactions to them. They lack
confidence in their abilities and feel as though they have no stable, internal
value as persons.
The goal of humanistic therapy is to persuade people that they do have
intrinsic value and to help them achieve their own unique positive potential as
human beings.
