How do we classify and learn about Psychological Disorders??? We use the DSM DSM-IV-TR:DSM-IV-TR: – the big book of disorders –Classifies disorders on the basis of their distinctive features or symptoms Classifies and describes the disorders but does NOT NOT NOT discus their causes or treatments…WHY??
Two Major Classifications in the DSM Neurotic Disorders Distressing but one can still function in society and act rationally. Psychotic Disorders Person loses contact with reality, experiences distorted perceptions. John Wayne Gacy
So How does the DSM work?? Axes or Dimensions (5 in total)Uses a system of Axes or Dimensions (5 in total) that help the examiner conduct a comprehensive evaluation of a person’s mental health Axis I and Axis IIAxis I and Axis II –Contains lists of disorders Axis IIIAxis III –Contains general medial conditions and diseases Axis IVAxis IV –Any psychosocial and environmental problems that may impair function Axis VAxis V (GAF) –Global assessment of functioning (GAF) –A numerical value that indicates overall level of mental health
A Sample DSM Evaluation Angela was rarely reinforced for any of her accomplishments at school, but she gained her mother’s negative attention for what Mrs. Savanti judged to be poor performance at school or at home. Mrs. Savanti repeatedly told her daughter that she was incompetent, and any mishaps that happened to her were her own fault.......When Mr. Savanti deserted the family, Angela’s first response was that somehow she was responsible. From her mother’s past behavior, Angela had learned to expect that in some way she would be blamed. At the time that Angela broke up with her boyfriend, she did not blame Jerry for his behavior, but interpreted this event as a failing solely on her part. As a result, her level of self-esteem was lowered still more. Angela’s uncertainties intensified when she was deprived of the major source of gratification she had, her relationship with Jerry. Despite the fact that she was overwhelmed with doubts about whether to marry him or not, she had gained a great deal of pleasure through being with Jerry. Whatever feelings she had been able to express, she had shared with him and no one else. Angela labeled Jerry’s termination of their relationship as proof that she was not worthy of another person’s interest. She viewed her present unhappiness as likely to continue, and she attributed it to some failing on her part. As a result, she became quite depressed. The Clinical Picture of Angela Savanti
The Diagnosis Axis IAxis I –Major Depressive Disorder Axis IIAxis II –Dependent personality Disorder Axis IIIAxis III –Diabetes Axis IVAxis IV –Problems related to social environment (termination of relationship – Jerry and Father) Axis VAxis V –GAF = 55 The Clinical Picture of Angela Savanti
A Cautionary Note… The DSM-IV provides an invaluable tool to psychologists, but it doesn’t come without its criticismsThe DSM-IV provides an invaluable tool to psychologists, but it doesn’t come without its criticisms Some believe it can turn normal problems of living into “diseases” – i.e. ADHD or the argument over PMSSome believe it can turn normal problems of living into “diseases” – i.e. ADHD or the argument over PMS Also, some believe the DSM-IV makes diagnosis of disorders scientific when they are actually highly subjectiveAlso, some believe the DSM-IV makes diagnosis of disorders scientific when they are actually highly subjective The problem of Labeling…The problem of Labeling…
The Influence of Labels Should people who were once diagnosed with a psychological problem carry that diagnosis for the rest of their lives? Can lead to stigmatization Can lead to stigmatization –The Rosenhan Study –rooms for rent story Can change reality Can change reality –a student is “gifted” or “hostile”

Current Perspectives…cont. Bio-Psycho-Social Perspective: biologicalpsychological socioculturalassumes biological, psychological and sociocultural factors combine to interact causing disorders. One Example The Diathesis-Stress Model Inherited predisposition To develop the disorder Diathesis = predisposition or vulnerability EnvironmentalStressors Disorder
Are you Insane?? Mental Illness vs. Insanity Mental Illness Mental Illness –A medical decision Insanity Insanity –A legal decision –To be insane a person must be unable to control behavior and be unaware that behavior is wrong –Insanity defense is based on the principle that punishment is justified only if the person is capable of understanding and controlling his or her behavior

Early Theories on Mental Illness and Disorders Afflicted people were possessed by evil spirits.
Early Theories on Treatment Music or singing was often used to chase away spirits. In some cases trephining was used: Cutting a hole in the head of the afflicted to let out the evil spirit.
Early Theories on Treatment Another theory on treatment was to make the body extremely uncomfortable. Hopefully, this would drive out the evil spirits
History of Mental Disorders In the 1800’s, disturbed people were no longer thought of as madmen, but as mentally ill. Did this mean better treatment? They were first put in hospitals.
Early Mental Hospitals They were nothing more than barbaric prisons. The patients were chained and locked away. Some hospitals even charged admission for the public to see the “crazies”, just like a zoo.
Philippe Pinel and Dorethea Dix Doctors who were the first to take the chains off and declare that people are sick and “a cure must be found!!!” Moral-treatment Movement Out of this movement, large state- supported asylums were built Good intentions, but poor concept….why??
Deinstitutionalization New Drugs and a feeling of optimism – “all could make it if given a chance” – lead to an emptying of mental hospitals Most ended up either homeless or in prisons
