Psychological Disorders
(Abnormal or Clinical Psychology)

We wlll look at a film excerpt from Bellevue: Inside Out

Consider the following questions about these three people:

What did you see/hear which was "abnormal"?

How did the people at the hospital treat them?


Abnormal Behavior: Is It A Disease?


[devil]


Demonic Possession

  Abnormal behavior  ->   devil's work

  • Belief that the "abnormal" individual acts in that manner because of the influence of evil forces (such as the Devil).

DSM-5

DSM-5 (2013)

"Medical Model"

Abnormal behavior  ->  disease
  • Modern psychiatry & clinical psychology treats abnormal behavior as a disease.
  • Diagnosis: distinguishing one illness from another
  • Etiology: the cause & developmental history of the illness
  • Prognosis: a forecast or prediction about the probable course of the illness
  • Social Stigma of mental illness: people feared, rejected, etc.

[Th. Szasz, MD]
Thomas Szasz, MD
(died 2012)

Deficient Problem Solving

  • Abnormal behavior  ->   socially unacceptable
  • Thomas Szasz, MD: "Abnormal" is a moral judgment about behaviors we don't like.
  • Persons who are "abnormal" don't suffer an illness of the mind; illnesses can only be physical
  • This is very much a minority viewpoint, but does get us to think

Abnormal Behavior: What Does "Abnormal" Mean?

Psychology uses the term "abnormal" in at least three different ways:

1. Deviance: The behavior(s) deviates or is different from what society considers to be acceptable.

2. Maladaptive Behavior: There is an impairment in daily life which comes from the behavior(s)

3. Personal Distress: The individual reports significant levels of personal pain or distress

 


 
DSM

Psycho-diagnosis: Classifying Disorders

"A mental disorder is a syndrome characterized by clinically significant disturbance in an individualís cognition, emotion regulation, or behavior that reflects a dysfunction in the psychological, biological, or developmental processes underlying mental functioning. Mental disorders are usually associated with significant distress or disability in social, occupational, or other important activities. An expectable or culturally approved response to a common stressor or loss, such as the death of a loved one, is not a mental disorder. Socially deviant behavior (e.g., political, religious, or sexual) and conflicts that are primarily between the individual and society are not mental disorders unless the deviance or conflict results from a dysfunction in the individual, as described above." (American Psychiatric Association, 2013, p. 20)
Mental disorders affect our lives negatively
Cultural responses to stress and loss like crying or grieving are not mental disorders
The fact that a specific culture doesn't like or approve of a person's political, religious, or sexual behavior does not make that behavior evidence of a mental disorder.  



Anxiety Disorders

Central Issue in All Anxiety Disorders  ->  Fear - Apprehension - Anxiety

Five (5) Types

1. Generalized Anxiety Disorder

  • Chronic high levels of anxiety not tied to a specific threat
  • Constant worry
  • Physical symptoms such as dizziness, diarrhea, trembling, muscle tension

2. Phobic Disorder

[Different Phobias]

  • Irrational fear of a specific object or situation which is not actually dangerous
  • The Phobia List
Some Common Phobias

Animals = Zoophobia
Closed spaces = Claustrophobia
Crossing bridges = Gephyrophobia
Death or dying = Thantaophobia
Heights = Acrophobia
Snakes = Ophidiophobia
Spiders = Arachnophobia
Storms = Brontophobia

Number 13 = Triskaidecaphobia


3. Panic Disorder & Agoraphobia

  • Sudden & overwhelming feelings of anxiety & fear
  • Agoraphobia = Fear of going out into public places

4. Obsessive-Compulsive Disorder

  • Persistent, uncontrollable intrusions of unwanted thoughts (obsessions) or urges to engage in useless rituals (compulsions)
  • Obsessions such as fear of harming another or self, failure at work, sexual acts
  • Compulsions such as consistent hand washing, checking locks on door, touching objects in a certain order
4. Post-traumatic Stress Disorder (PTSD)
  • Originally recognized as a distinctive disorder during the early 1970s (Vietnam War).
  • For the general population, a lifetime prevalence rate of 7-8% (10% among F & 5% among M)
  • The diagnosis requires the following elements:
    • Exposure to an event involving danger of death or witnessing death of others
      • War, terrorism, rape, prison stay, assault, domestic abuse, emergency service responder work (EMT, firefighter, etc.)
      • Note that we too often exaggerate what might be a cause of PTSD
    • Symptoms
      • Reliving the event in flashbacks, memories, nightmares, etc.
      • Avoidance reactions: emotional numbing, detachment feelings, lack of interest in activities, feeling one has no future, inability to remember aspects of the trauma
      • Arousal: concentration difficulties, startle reactions, hypervigilance, irritability & anger, sleep difficulties, dizziness, fainting, heart palpitations
    • Symptoms have been present for at least 30 days
      • If less than 30 days following event, = "acute stress disorder"
      • Symptoms of PTSD may appear weeks or months after the traumatic event. Their failure to appear immediately after the event is not an indication against the diagnosis.

Etiology (= Causes): Where do Anxiety Disorders come from?

1. Biological

  • Moderately high level of concordance in identical twins (ca. 35%) compared to fraternal twins (ca. 15%). This suggests some genetic vulnerability.
  • May be related to problems in neural circuits using the neurotransmittter GABA which generally inhibits our nervous system's responses. If it is not working properly, the nervous system may become overly excited and reactive to even small matters.

2. Conditioning & Learning: Fears come from experiences in life

  • Some studies have found people can identify specific events which gave rise to the phobia
  • Martin Seligman's (1971) Preparedness Theory: some people are biologically (often, genetically) more predisposed to develop fears than others

3. Cognitive Factors

  • Some individuals may have a thinking style which promotes anxiety disorders through
    • Misinterpreting nonthreatening situations as threatening
    • Overemphasizing threat
    • Selectively recalling threat information
  • Research shows that anxious individual are much more likely to evaluate statements as threatening than non-anxious individuals

4. Personality Factors

  • High levels of neuroticism (one of the Big 5 traits) often present: nervous, insecure, gloomy, guilty

5. Stress

  • Clearly seen in Post-Traumatic Stress Disorder (PTSD)
  • Other types of anxiety disorders often preceded by high levels of stress
