Chapter 17: The Natures and Causes of Mental Disorders
-Emil Kraepelin: created the first comprehensive classification system of psychological disorders
What is Abnormal?
-abnormal refers to any departure of the norm
-most important feature of a mental disorder is not whether a persons behavior is abnormal, but whether it
is maladaptive
Perspectives on the Causes of Mental Disorders
-mental disorders are caused by the interaction of hereditary, cognitive, and environmental factors
The Psychodynamic Perspective
-Freud: mental disorders originate in intrapsychic conflict produced by the three components of the mind
the id, ego, and superego
-for some, the conflicts become so severe that the minds defense mechanisms cannot produce a resolution
that is enough for mental health
-the resultant is the defense mechanisms distort reality
-psychodynamic therapists attempt to make their clients aware of their intrapsychic conflict and defense
mechanism failures to regain mental health
The Medical Perspective
-Hippocrates: believed that excesses of the four humors (black bile, yellow bile, blood, and phlegm) led to
emotional problems
-today many people with mental disorders are not longer treated in mental hospitals, instead they are
treated on an outpatient basis with drugs
-the medical model suggests that mental disorders are caused by specific abnormalities of the brain and

nervous system and should be approached for treatment in the same manner as physical illnesses
The Cognitive-Behavioral Perspective
-mental disorders are learned maladaptive behavior patterns that can be understood by focusing on
environmental factors and a persons perception of those factors
-example, a persons excessive use of alcohol may be reinforced by the relief from tension
-what also counts is a persons ongoing subject interpretation of the events taking place in his/her
The Humanistic Perspective
-mental disorders arise when people perceive that they must earn the positive regard of others becoming
overly sensitive to the demands and criticisms of others
-they begin to feel no control over the outcomes of the important events in life resulting in depression
-humanistic therapy help people realize that they do have intrinsic value
The Sociocultural Perspective
-cultures play a significant role in the development of mental disorders
-mental disorders exist that appear to occur only in certain cultures—a phenomenon called culture-bound
The Diathesis-Stress Model of Mental Disorders
-a casual account of mental disorders based on the idea that mental disorders develop when a person
possess a predisposition for a disorder and faces stressors that exceed his or her abilities to cope with them
-the combination of a persons genetics and early learning experiences yield a predisposition for a mental

Global Assessment
of Functioning
(GAF) scale
-GAF=100 represents the absence or near absence of impaired functioning
-GAF=represents serious problems in functioning
-GAF=10 represents impairment that may result in injury
Some Problems with DSM-IV Classification
-diagnosis and treatment based on the DSM-IV emphasizes biological factors thus potential cognitive and
environmental determinants may be overlooked
-another problem is reliability
-diagnosing a psychological disorder only describes the symptoms of the disorder and does not explain the
cause and psychological processes
The Need for Classification
-Thomas Szasz: believed that all attempts to classify mental disorders should be abandoned because
labeling can have negative effects
-proper classification has advantages for the patient: recognition of a specific diagnostic category leads to
the development of successful treatment
-a patient may have multiple symptoms, but before the cause of the disorder can be discovered the primary
symptoms must be identified first
