Title: Psychological Disorders
1Chapter 12
- Psychological Disorders
- Nearly 1 of every 4 Americans are diagnosed with
a mental heath disorder each year.
2Section 1 Defining What Is Normal
- Psychopathology
- Scientific study of
mental, emotional, and behavioral disorders - Term used to refer to a disorder
- Concepts in Normal vs. Abnormal Behavior
- Subjective Discomfort
- Private feelings of anxiety, depression, or
emotional distress - Statistical Abnormality
- Having extreme scores on some dimension, such as
intelligence, anxiety, or depression (see graph) - Social Nonconformity
- Disobeying societal standards for normal conduct
may lead to destructive or self-destructive
behavior - Situational Context
- Social situation, behavioral setting, or general
circumstances in which an action takes place - Is it normal to walk naked around strangers? If
you are in a locker room and in the shower area,
yes! - Cultural Relativity
- Judgments are made relative to the values of
ones culture
3There is no absolute normal or abnormal behavior,
therefore criteria were established to help
determine if a behavior is abnormal for an
individual.
- Three criteria for determining abnormal behavior
(book lists only 2) - All three criteria do not have to be met for a
person to be diagnosed with a psychological
disorderdiagnoses involve value judgments - Deviant - does it violate societal norms
- Maladaptive - does it impair a persons everyday
behavior - Causing personal distress does the person
experience discomfort, stress or pain of some
kind from the behavior - A continuum of normal/abnormal
- Antonyms such as normal vs. abnormal imply that
people can be divided into two distinct groups,
when in reality, it is hard to know when to draw
the line
4Disordered Behavior
- Mental Disorder
- Significant impairment in psychological
functioning is present - Psychotic Disorder
- Severe psychiatric disorder characterized by
hallucinations and delusions, social withdrawal,
and a movement away from reality - Organic Mental Disorder
- Mental or emotional problem caused by brain
pathology (e.g., brain injuries or diseases)
5Neurosis
- Archaic term
- Once used to refer to excessive anxiety,
somatoform, dissociative disorders, and some
kinds of depression
6Classifications of Major Disorders
- The diagnoses of disorders are made on Axes I and
II, with most falling on Axis I. - The remaining axes are used to record
supplemental information. A persons physical
disorders are listed on Axis III, and the types
of stress they have experienced in the past year
on Axis IV. Axis V estimates the individuals
current level of adaptive functioning. - The goal of this multiaxial system is to impart
information beyond a traditional diagnostic
label. - Axis I Clinical Syndromes
- Axis II Personality Disorders or Mental
Retardation - Axis III General Medical Conditions
- Axis IV Psychosocial and Environmental Problems
- Axis V Global Assessment of Functioning
7Types of Mental Disorders Defined in The DSM
(Diagnostic and Statistical Manual of Mental
Disorders)
8General Risk Factors for Developing a Mental
Illness

- Poverty, homelessness, overcrowding, stressful
living conditions - Family Factors

or criminal - Poor child discipline
- Severe marital or relationship problems
- Psychological Factors
- Stress, learning disorders, and low intelligence
- Biological Factors

9Insanity VS. Mental Disorder
- Insanity
- A legal term referring to an inability to manage
ones affairs or to be aware of the consequences
of ones actions - An insane person can not determine right from
wrong - Can only be established though testimony of an
expert witness in a court of law - May be psychologist, psychiatrist, and so on
- Mental Disorder
- Any mental, emotional, or behavioral abnormality
causing distress or interfering with a persons
ability to function

- Person is preoccupied with having a serious
illness or disease - Interpret normal sensations and bodily signs as
proof that they have a terrible disease - No organic cause can be found
- constant self-examination and self-diagnosis, and
a preoccupation with one's body. - Many individuals with hypochondriasis express
doubt and disbelief in the doctors' diagnosis,
and report that doctors reassurance about an
absence of a serious medical condition is
unconvincing, or un-lasting. - Many hypochondriacs require constant reassurance,
either from doctors, family, or friends, and the
disorder can become a disabling torment for the
individual with hypochondriasis, as well as his
or her family and friends.
22Somatization Disorder
- Person expresses anxieties through numerous
physical complaints - Many doctors are consulted but no organic or
physical causes are found - (also Briquet's disorder or, in antiquity,
hysteria) - Patients with Somatization Disorder will

FIGURE 12.4 (left) Glove anesthesia is a
conversion reaction involving loss of feeling in
areas of the hand that would be covered by a
glove (a). If the anesthesia were physically
caused, it would follow the pattern shown in (b).
(right) To test for organic paralysis of the arm,
an examiner can suddenly extend the arm,
stretching the muscles. A conversion reaction is
indicated if the arm pulls back involuntarily.

Disorders
- Psychosis loss of contact with shared views of
reality - Delusions and hallucinations are core features of
psychosis - Delusions
- False beliefs that individuals insist are true,
regardless of overwhelming evidence against them - Hallucinations
- Imaginary sensations, such as seeing, hearing, or

world - Most common psychotic hallucination is hearing
voices - Note that olfactory hallucinations sometimes
occur with seizure disorder (epilepsy) - Flat Affect

impairment in old age caused by brain
deterioration - Archaically known as senility
- Experiences could really occur!
- Paranoid Psychosis
- most common delusional disorder
- Centers on delusions of persecution
- Alzheimers Disease
- Symptoms include impaired memory, confusion, and
progressive loss of mental abilities - Ronald Reagan was perhaps the most famous
Alzheimers victim - Common Causes
- Circulatory problems, repeated strokes, and
shrinkage and atrophy of the brain - Delusional Disorder
- Marked by presence of deeply held false beliefs
(delusions) - May involve delusions of grandeur, persecution,
jealousy, or eroticism
29Schizophrenia
- Psychotic disorder characterized by
hallucinations, delusions, apathy, thinking
abnormalities, and split between thoughts and
emotions - Does NOT refer to having split or multiple
personalities
30The Four Subtypes of Schizophrenia
- Disorganized Type
- Incoherence, grossly disorganized behavior,
bizarre thinking, and flat or inappropriate
emotions - Catatonic Type
- Marked by stupor, rigidity, unresponsiveness,
posturing, mutism, and sometimes agitated,
purposeless behavior - Paranoid Type
- Preoccupation with delusions
- Also involves auditory hallucinations that are
related to a single theme, especially grandeur or
persecution - Undifferentiated Type
- Any type of schizophrenia that does not have
paranoid, catatonic, or disorganized features or
symptoms
31Causes of Schizophrenia
- Environment
- In utero exposure to the flu
- Malnutrition during pregnancy
- Complications during birth
- Psychological Trauma
- Psychological injury or shock, often caused by
violence, abuse, or neglect - Disturbed Family Environment
- Stressful or unhealthy family relationships,
communication patterns, and emotional atmosphere - Heredity
- Biochemical Abnormality
- Disturbance in brains chemical systems or in the
brains neurotransmitters - Dopamine
- Neurotransmitter involved with emotions and
muscle movement - Works in limbic system
- Dopamine over-activity in brain may be related to
schizophrenia
32FIGURE 12.8 Dopamine normally crosses the synapse
between two neurons, activating the second cell.
Antipsychotic drugs bind to the same receptor
sites as dopamine does, blocking its action. In
people suffering from schizophrenia, a reduction
in dopamine activity can quiet a persons
agitation and psychotic symptoms.

and unique to a specific society, we call
theseCultural Maladies
Culture and Mental Health
- Amok
- Men from Malaysia, Laos, Philippines, and
Polynesia who feel they have been insulted will
brood then erupt violently - Susto
- Insomnia, irritability, phobias, and an increase
in sweating and heart rate affecting Latin
Americans who are frightened by a black magic
curse - Ghost Sickness

- Major Risk Factors
- Drug or alcohol abuse
- Prior suicide attempt
- Depression or other mood disorder
- Availability of a firearm
- Severe anxiety or panic attacks
- Family history of suicidal behavior
- Shame, humiliation, failure, or rejection
FIGURE 12.15 Suicidal behavior usually progresses
from suicidal thoughts, to threats, to attempts.
A person is unlikely to make an attempt without
first making threats. Thus, suicide threats
should be taken seriously (Garland Zigler,
1993).
45Factors Affect Suicide Rate
- Gender
- Men are more likely to complete suicide, but more
women attempt - Ethnicity
- Rates vary from country to country, but
Caucasians have higher suicide rates - Native Americans have highest suicide rate in
country - Age
- Suicide rates increase with age
- Marital Status
- Married individuals have lower suicide rates
46Common Characteristics of Suicidal Thoughts and
Feelings (Shneidman)
- Escape
- Unbearable Psychological Pain
- Emotional pain that the person wishes to escape
- Frustrated Psychological Needs
- Such as searching for love, achievement, or
security - Constriction of Options
- Feeling helpless and hopeless and deciding that
death is the only option left
47The Psychology of SuicideAdapted from Suicide
and Crisis Intervention Service, MemphisTraining
Manual
- The suicidal person dose not fear death less than
others they do fear something in life more. - Those who fear death fear more the process than
the result, by choosing suicide they pick the
manner of death. - People with terminal or chronically painful
illness may choose suicide out of self-love.
They do not wish to put themselves through
seeming needless pain. - People who have committed an act they consider
reprehensible may choose suicide out of
self-hate. They perform a self conviction and
execution. - Someone in extreme conflict with another may
choose suicide out of hatred for another. They
kill themselves to punish the other person, in a
sense they accuse/blame the other person for
their own death. - Someone suffering from psychosis may not choose
suicide, but rather not realize that death will
be the result of their actions. - People in need of other attention or assistance
may commit a near-suicidal act to secure
attention. Unfortunately they may be more
successful than they intended.
48The Signs of SuicideAdapted from Suicide and
Crisis Intervention Service, MemphisTraining
Manual
- Lack of concern about their appearance, grooming,
health, or clothing. - Withdraws from social contact.

or pain. Perceives a real threat to happiness. - Acts impulsively.

- Reduced fantasy or living capacity. Can not find
joy in anything. - Talks symbolically of death or may even have a
plan for their own death. - Signs are not limited to the ones above, any
major change in behavior may signal a problem.
49What Can You Do to Prevent A SuicideAdapted
from Suicide and Crisis Intervention Service,
MemphisTraining Manual
- First, protect your own psyche you can not
really prevent or cause others actions. You are
not responsible for others decisions. - Once you understand the above statement you can
proceed to try to help someone else. Some
suggestions - Always try to get the person profession help.
- Listen empathetically and non-judgmentally to the
person. - Identify what they really fear and help provide
HOPE for overcoming the problem. - Help the person identify real solutions that they
can DO. (Never leave a solution with a dont
only, that behavior needs to be replaced with
something a do.) - Check on the person as often as you can until the
crisis has been resolved. - Follow up with professional help yourself if
needed, dont find yourself being drawn in to
hopelessness.
