Personality Theories

Psychoanalytic


Childhood experience, ucs influence, dynamics,
conflict, defenses, development and identification
Humanistic
 Focus on self & self-actualization,
existential approach, flow & happiness
 Social-Cognitive Theory


Beliefs, thoughts & personal constructs, often
acquired from social interactions, shape behavior
Behavioral Theory

Learning history, self-perception theory, selfcontrol

Defining Abnormality
Medical approach
 Statistical approach
 Functional approach

These reflect two basic views of disorders
--brain based
--behavior/experience/situation based
The “two worlds” of psychiatry
DSM-IV
Axis 1: Syndromes (Scz, Depress, etc.)
 Axis 2: Retardation & Personality Disorders
 Axis 3: General Medical Condition
 Axis 4: Social/Environmental Problems
 Axis 5: Global Assessment & Coping
 Older classification (primarily of Axis 1 & 2)
dichotomized: Neuroses & Psychoses
 Mood (Dep. Bipolar) vs. Thought (Scz) Disrdr
 Now replaced by highly elaborated DSM-V

Prevalence of Neurotic Disorders by Age
Prevalence of Neurosis by Age & Social Class
Prevalence of Psychosis by Age & Gender
Heritability of Psychosis: Schizophrenia
Scz incidence & poverty/residential area
Some Interim Conclusions
Psychoses (focus on SCZ) is a disorder of
heredity and/or prenatal environment
 But it’s also a disorder of poverty (and that may
be bidirectional)!
 Another view of prevalence and recent dramatic
changes in prevalence

Incidence & Prevalence
Schizophrenia: approx. 1%
 Bipolar Disorder: approx. 1%
 Depression:

History

Earliest history

Psychological Treatments

Focused on changing the way the patient thinks
and behaves

Involves discussion, instruction, or training

Over 500 different forms of such treatment




Psychodynamic
Humanistic
Behavioral
Cognitive
Psychodynamic Approaches

Illness result of unconscious conflicts developed early in
childhood

Defense mechanisms shield from the inner conflict
 This can lead to symptoms of mental illness

Treatment: Uncovering unconscious desires and
conflicts, and resolving them
 Integrate thoughts and memories coherently
Psychodynamic Approaches

“Working through” the conflict

Transference


Used as a therapeutic tool
In order to be effective, therapist must remain
neutral
Humanistic Approaches

Based off of Freud’s “talking cure”

However, less focused on basic drives

Instead, focus on creating meaning

Clients need to take responsibility for their lives
and actions, and live in the “here and now”
Humanistic Approaches

Treatment directed at reducing or eliminating
problematic behaviors (because behavior is all
there is!)

Institutional control mechanism (humane)

Approach involves replacing old habits with more
effective or adaptive behaviors

Classical conditioning, operant conditioning, modeling
Behavioral Approaches
Classical Conditioning Techniques

Treatment of Phobias

Extinguish the association between the neutral
stimulus and the fearful stimulus

Exposure Therapy



Train clients in deep muscle relaxation, pair
relaxation with the fearful stimulus
Create a hierarchy of progressively more frightening
stimuli
Systematic desensitization: gradual exposure to the
real phobic stimulus
Systematic Desensitization
Behavioral Approaches
Operant Conditioning Techniques

Token economies



Earn tokens for positive behaviors, which can be exchanged
for prizes
Shaping
Contingency Management

Cognitive-Behavioral Approaches

Rational Emotive Behavioral Therapy
(Albert Ellis)

People typically think that an event
causes them to behave a certain way

Practice new ways skills or thought techniques
Eclecticism

there are often many
causes of mental
illness
Client-Therapist Relationship

Therapeutic Alliance

Support

Trust

Hope

Understanding
Group Therapies



problems, less on the
individuals’ emotions




Social support
Share advice, information
Observe other peoples’
successes

may reflect a larger issue for the entire family
or relationship
Can be extended to
 treating children
who have little control

(work with family tol change
situation/mileau)
Biomedical Treatments


Spinning
Biomedical Treatments

precise and used as a last
resort treatment
Electroconvulsive Therapy (ECT)

Brief electrical current
passed through the brain
causing a convulsive seizure

Originally developed to treat
schizophrenia

Very effective for treating
severe depression (70-90%
effective)

Memory impairment

Mechanisms are not known
Different Therapies for Different
Conditions (& Sometimes a Mix)

Medical: Brain targeted drug interventions
examples:
--SCZ: Dopamine receptor blockers (the
better the block the more effective it is)
--Other neurotransmitters involved as well
--Depression: ex. Norepinephrine uptake or
release+, Serotonin release+, & a host of
other neurotransmitter controls involved
-- Electro-convulsive shock therapy!
Pharmacological Treatments

Psychotropic drugs

Not only helped treat patients, but also further
understanding of the illness
Pharmacological Treatments

Antipsychotics



Treat positive symptoms of schizophrenia
Not effective for treating the negative symptoms
Most common are Thorazine, Haldol and Stelazine

Atypical Antipsychotics


Treat negative symptoms of schizophrenia, too
Risperdal, Clozaril, Seroquel

local community centers instead of institutions
Fewer people spending their lives in institutions
Shorter stays
Downside



Efficacy vs. Utility


conclusions about the efficacy of particular
treatments

In many circumstances, patients have more than
one illness

Also, therapists typically use more than one
approach

patients who received treatment fared
better than those without
Are all Therapies Equally Effective?
Who provides the most effective psychological
treatment?

Number of years of practice?



Not necessarily
No


Therapy alone 52% effective

Drug AND therapy 85% effective!
(New England Journal of Medicine, 2000)
Are all Treatments Equally Effective?

Treatment more effective than no
treatment

Combining treatments appears most
beneficial

Some therapies seem particularly effective
for specific disorders



Modern treatments are much more
effective and humane than past
treatments

Some people are able to cognitively
overcome even serious levels of disorders

Available to psychotherapy

Find meaning in some symptoms

Able to live normally or quasi-normally



Seek it! Ask for advice, or set up an appointment
with a counselor. It’s not a weakness.

Make sure the therapist is a good match for you!

Remember it can take time and you may face
some setbacks, but also…
