Why diagnose?
1) Usefulness for treatment planning2) Implications for prognosis3) Contribution to protecting consumers of
mental services4) Value in enabling the therapist to convey
empathy5) Role in reducing the probability that certain
easily frightened people will flee from treatment
McWilliams N (2011)

Has psych diagnosis labeled rather than enabled patients?
Pros of diagnosis• Provides boundary and
enables psychiatrists maintaining its integrity
• Framework to disseminate the knowledge gained
Cons of diagnosis• Overmedicalization• Diagnostic overshadowing
(physical symptoms misattributed to mental illness)
• Ticket to long-term institutionalization
• Patients may be deprived of their legal capacity

Three questions for psychiatrists
1. What is psychiatry’s domain of study?2. How can one make reliable and valid
observation in that domain?3. How is the domain generated by the brain?

The Perspectives of Psychiatry
![Page 11: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/11.jpg)
Systematic Psychiatric Evaluation
1. A detailed history2. A history obtained and presented in a specific
sequence3. A history obtained from multiple sources
(including collateral informants)4. A systematic mental state exam5. A careful differentiation between
observations and interpretations
![Page 12: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/12.jpg)
Mental state exam
1. Appearance/behavior2. Speech
1. Volume2. Rate3. Rhythm4. Fluidity5. Spontaneity6. Latency7. Thought disorder
3. Mood and affect (observed and reported)
1. Stability, reactivity, appropriateness
2. Vital sense3. Self-attitude4. Thoughts of death,
suicide, homicide

Mental state exam (ctnd.)
4. Abnormal Perceptions1. Illusions2. Hallucinations
5. Content of Thought1. Delusions2. Obsessions3. Compulsions4. Phobias

The Life-story perspective:
1. Is a personal perspective2. Is based on the logic of narrative with its triad
of setting, sequence, and outcome, which is produced meaningfully and understandably
3. It applies to psychiatric conditions that arise from something an individual has encountered
4. It suggests rescripting as the treatment goal
![Page 16: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/16.jpg)
The life-story perspective
A recently widowed patient may seek treatment for feelings of loneliness and sadness following the loss of her husband. Her clinician understands her symptoms as arising from loss and uses psychotherapy to help the patient “rescript” her life story and regain a feeling of mastery over her circumstances. Type of story told may be less important than the therapeutic relationship and other factors.
Peters ME et al. 2011
![Page 17: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/17.jpg)
Life story
Pros• Vivid way to capture a part
of reality• Best way to enhance our
natural sympathy• Whole / holistic
appreciation
Cons• Bias• Causation contrived• Difficult to refute• Must deal with fiction
![Page 18: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/18.jpg)
The dimensional perspective:
1. Focuses on individual psychological dimensions that are universal, measurable, and graded (cognition and temperament)
2. Has an underlying conceptual triad of potential, provocation, and response
3. Applies to psychiatric conditions that arise from who a person is
4. Suggests guidance as the treatment goal
![Page 19: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/19.jpg)
Quantitative dimensions
• Intelligence (mental retardation / ASD)– Defining a psychological disposition– Is a potential to change
• Personality type (personality disorders)
![Page 20: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/20.jpg)

The behavior perspective:
1. Seeks to identify and explain disorders of individual choice
2. Has an underlying conceptual triad of choice, physiologic drive, and conditioned learning
3. Applies to psychiatric conditions characterized by what a person does
4. Suggests interrupting as the treatment goal,prompting choice of recovery.
![Page 22: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/22.jpg)
• Dependence / abuse• Anorexia / bulimia nervosa
![Page 23: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/23.jpg)
Stage
• Precomtemplative stage– No thoughts of changing behavior
• Contemplative stage– Considering change but they were not ready to
accept the implications for the way of life• Action stage– Ready to act against the behavior
![Page 24: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/24.jpg)
Therapies considered
Treatments of drive• Satisfaction replacements
– Methadone, nicotine patch
• Drive reduction– Medroxyprogesterone
acetate
• Response punishment– Disulfiram [antabuse]
• Reinforcement blockage– Naltrexone
• Harm reduction
Treatments of social learning• Redirection with
psychotherapy to better consequences
• Rewards for appropriate choices and responses(token economies)
• Social restructuring and rehabilitation(family therapy)
![Page 25: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/25.jpg)
The disease perspective:
1. At its essence is about an abnormality in the structure or function of the brain expressed in the development of a syndrome
2. Has an underlying conceptual triad of clinical syndrome, pathology, and etiology
3. Applies to psychiatric conditions that a patient has
4. Suggest curing as the treatment goal
![Page 26: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/26.jpg)
Disease reasoning
• Documenting a patient’s clinical history• Conducting a physical and psychological exam• Observing the progress of symptoms over time You just assess how closely the pt resembles other pts• Identifying symptoms• Linking the symptoms to a pathology• Arriving at a cause
![Page 27: Systematic Psychiatric Evaluation](https://reader030.fdocuments.us/reader030/viewer/2022032513/55d09d23bb61eba1058b4791/html5/thumbnails/27.jpg)
Strengths and weakness
• Strengths– Familiar to most students of medicine– Produces testable models– Encourages research– Supportive of collaborative efforts btw physicians and basic
scientists• Weakness
– May neglect to consider the individual and his or her unique vulnerabilities to distress
– A disease model can be endlessly refined – Provokes the temptation to presume a brain source for all
matters of mental distress

• Relatively-known neuropathologies– Dementia– Delirium – …
• “Original madness” or “Psychosis”– Manic-depression– Schizophrenia
