Abnormal Psychology

This is not a course about the problems of someone else. Mental illness touches all of us at some time during our lives; if we are not the ones afflicted, then it will be a family member, loved one, or close friend.

The problem of abnormal behavior is personally relevant and emotionally charged, but in this course we will explore the problem from an objective and scientific point of view. Although we must be dispassionate in our study of the problem, it is important that we keep in mind the importance and the intense personal ramifications of what we are studying.

PsychopathologyPsychopathology ... beyond behavior

1. Thought: problems in how and what we think

2. Emotion: problems in momentary mood and chronic temperament

3. Conation: problems in momentary motives and persistent needs

... the “subject matter” and the “data base”

The Definition of “Psychopathology”The Definition of “Psychopathology”

Topics: The importance of the historical context

A.A. UnderstandingUnderstanding: scientific description and explanation... the history of our curiosity

B.B. InterventionIntervention: the change technologies

... the history of our compassion

4

History History ... of understanding and intervention

3 broad perspectives on both:

1. Sociocultural: natural and supernatural

2. Biological: body and brain

3. Psychological: three theories of the mind

Examples:

2.2. PsychologyPsychology: three “meta-theories”

A. Learning Theories: adaptation to the present and the behavior

and cognitive therapies

B. Phenomenological Theories: growth into the future and the

directive and non-directive therapies

C. Psychodynamic Theories: conflict from the past and the

psychoanalytic therapies

3.3. Sociocultural factorsSociocultural factors: natural and supernatural

Understanding problems, in the past the causes of problems

Intervening with people, in the future the course of life

The Lesson Lesson of History

“The lessons of the past

were obliterated by the aspirations

of the present.”

- Alexander Leighton

57

The Lesson Lesson of History

“It ain’t what you don’t know

that gets you; it’s the things you

know that ain’t so.”

- Mark Twain

58

The Lesson Lesson of History

“Confusion now hath made

his masterpiece.”

- MacBeth

59

The Lesson Lesson of History...Limitations to Progress

1. Understanding (finding causes): post hoc explanations correlates and causes longitudinal and experimental research the problem of base rates (BR)

60

The Lesson Lesson of History...Limitations to Progress

2. Intervention (finding cures): placebo effects spontaneous remission (SR) superstitious behaviour publication bias

61

The Lesson Lesson of History...Limitations to Progress

Summary:

1. Understanding: it is hard to find out whywhy something

happens when it doesn’t happen very oftendoesn’t happen very often

2. Intervention: it is hard to find out if anything makes a makes a

differencedifference to the course when that course is

erraticerratic and unpredictableunpredictable

The Modern Diagnostic System(DSM)

Why diagnosis?

... a present description

...with future implications

“Diagnosis is prognosis”

67

The Modern Diagnostic System(DSM)

DSM I (1952) and DSM II (1968)

DSM III (1980) and DSM IV (1994) ... TR, now

ICD 1 (1948) to 10 (1992) ... CM, now

68

The Modern Diagnostic System(DSM)

What have we gained?

1. ResearchResearch: no false positives

2. PracticePractice: no false negatives

... communication – in principle

... but research biasesbiases in practice

69

Diagnosis of psychopathology(DSM)

Axis I -Axis I - Clinical syndromes

Axis II -Axis II - Personality disorders (and MR)

Axis III -Axis III - Medical conditions

Axis IV -Axis IV - Stress

Axis V -Axis V - Coping (GAF)

Diagnosis of psychopathology(DSM)

“Other conditions that may

be the focus of clinical attention”,

including psychological factors

affecting medical conditions,

and the “V” code.

71

Diagnosis of psychopathology(DSM)

Issues: 1. reliability & validity

2. categories, dimensions & prototypes

(“polythetic” clarification)

3. comorbidity, artifactual & real

4. subjectivity & biases

5. the problem of labeling

Causal Factors and Viewpoints

Causation in psychopathology

1. Primary / necessary and sufficient causes

  2. Predisposing / contributory causes (and the concept of "relative risk")

  3. Precipitating / proximal and distal causes

4. Perpetuating / reinforcing (maintaining) causes

EXAMPLE: “25% of people experiencing Major Depressive Disorder (MDD) had an exit event.” “Only 5% of the control group without MDD had an exit event.” (“Exit Event”=physical departure of a significant person in the last six months”) Do exit events cause MDD?  Base rate for MDD (point prevalence): 2%

Take a population of 10,000 adults...200 MDD ... 25% with exit events = 509800 not MDD ... 5% with exit events = 490

So, we have 540 exit events, with fewer than 10% associated with MDD

Adjustment Disorders

Dx: inference of the causal importance of stress

Types: – depressed– anxious– conduct disturbance ...– ... “mixed” types– “N.O.S”

104

Anxiety Disorders Related to Extreme Stress

Acute Stress Disorder and Post-Traumatic Stress Disorder (PTSD)

Crucial for Dx: re-experiencing of an extremely traumatic event

The demographics of PTSD: BR and SR

Why do some people develop PTSD?– The nature of the trauma– The nature of the person– The nature of subsequent experience

Implications for treatment:– Social support, “debriefing”, exposure & stress-induced analgesia– The crisis in “Crisis-Counseling”
