The Concerns of Abnormal PsychologyDescribe, Explain, Predict and Control
Abnormal Psychology: Scientific study aimed at describing, explaining, predicting, and treating strange or unusual behavior.
Describe-Systematic observationsPsychodiagnosis: Attempt to describe, assess, and
systematically draw inferences about psychological disorders.
A diagnosis can be nothing more than a label!Labels describe a slice in time, not the changes
present in real lives.

The Concerns of Abnormal PsychologyDescribe, Explain, Predict and Control
Explain—Intrapsychic conflicts? Social isolation? Cognitive malfunctioning? Biology?
Predict—Proper diagnosis should allow for prediction based on other people in the past who shared the diagnosis.
Control—Therapy: Systematic intervention aimed at modifying client’s behavioral, emotional, and/or cognitive state.

Defining Abnormal BehaviorConceptual Definitions
Conceptual Definitions: Deviation from what is considered normal in a sociocultural context.Statistical deviation (think large z-scores here!)
Infrequent behaviorsAn IQ of 50 might be abnormal, how about 150?Requires quantificationDoesn’t consider cultural differences
Deviation from ideal mental healthProposed by humanistsWhat is ideal is in the eye of the beholder
Multicultural perspectivesContinued…

Defining Abnormal BehaviorCultural Considerations in Abnormal Behavior
Culture: Shared learned behavior transmitted from generation to generation.Culture is a powerful determinant of how behavior
is defined and treated.Cultural Universality: Origins, processes,
manifestation of disorders are the same across cultures.If true then diagnosis and treatment same for all
Cultural Relativism: What is normal/abnormal may vary from culture to culture.Not only do behaviors vary, but definitions of
acceptable change.

Defining Abnormal BehaviorPractical Definitions
Discomfort: If behaviors cause the actor pain (psychological or physical), then they are abnormal.
Deviance: Bizarre/unusual behaviorSimilar to statistical deviationVery subjective, though sometimes this is pretty
straightforwardDysfunction: Inability/loss of ability to perform one’s normal
roles.Compare performance with requirements for a roleCompare performance with potential

Defining Abnormal BehaviorIntegrated Definitions
Thomas Szasz: Mental illness is a myth:Used to control and change peoplePeople may suffer from “problems in living,” not “mental
illness.”Abnormal behavior labeled because it is different,
not because it is a reflection of an illnessUnusual belief systems are not necessarily wrongAbnormal behavior often the result of the fault of
society, not the individualDrapetomania: Mental illness of slaves who want to be
free.

Defining Abnormal BehaviorIntegrated Definitions
Perhaps the definition of abnormal should come from multiple sources.
Strupp & Hadley’s (1977) three vantage points for judging mental health:SocietyThe individualThe mental health professional
Wakefield (1992)To label dysfunction we must know natural functioningDefinition of dysfunction must come from biologyDysfunction must involve the harm component

Defining Abnormal BehaviorThe Surgeon General’s and DSM’s Definitions
“a clinically significant behavioral or psychological syndrome or pattern that occurs in an individual and that is associated with present distress or disability or with a significantly increased risk of suffering death, pain, disability, or an important loss of freedom.”

The Frequency and Burden of Mental Disorders
Prevalence: Percentage of people in a population with a disorder at a given time.
Lifetime Prevalence: Total proportion of people in a population who have ever had a disorder.
Incidence: Onset or occurrence of a disorder over a period of time.

The Frequency and Burden of Mental DisordersCurrent Research into Epidemiology
Schizophrenia affects 1% of Americans.Gender differences seen in different mental
disordersMales more likely to have substance abuse problems,
women more likely to have depression and anxiety.Age differences in onset and prevalence of
different disorders

The Frequency and Burden of Mental DisordersStereotypes About the Mentally Disturbed
Mental illness is strictly inheritedMental illness can never be cured and someone
with a mental illness will never be able to hold a job
Mental illness can be prevented with a strong will
A mentally disturbed person is always dangerous

Historical Perspectives on Abnormal Behavior
Prehistoric and ancient beliefsDemonology, treated by trephining or exorcism
Sympathetic Magic: The belief that by influencing things that are similar to a person or that were once close to that person, one can influence the person.
Homeopathic Magic: The type of sympathetic magic involving the belief that doing something to the likeness of a person will influence that person.
Contagious Magic: The type of sympathetic magic which involves the belief that what one does to something that a person once owned or that was close to a person will influence that person.
Magical beliefs are upheld by occasional “success”Bleeding or trepanation used to remove spirits.

Closing Thoughts
The study of abnormal psychology is complex and influenced by historical time.
No single explanation fits all situations.Biopsychosocial Approach: Biological,
psychological, and social factors must all be considered to explain and treat mental disorders
Guard against “Medical Student Syndrome”: Avoid diagnosing self and others!We all have all disorders, it simply a matter of
degree

understand such complex processesMultipath model consists of following factors:
