Ch. 16 - Treatment of Psychological Disorders Flashcards
What are the 3 most common reasons a person doesn’t seek treatment for a psychological disorder?
- Not realizing they have a mental disorder that can be effectively treated
- Attitudinal barriers (beliefs about being able to “handle it themselves”, the treatment would be ineffective, stigma, etc.)
- Structural barriers (physically prevent access to treatment)
What are the major types of therapists?
- Psychologist
- Psychiatrist
- Clinical/psychiatric social worker
- Counsellor
What are the two broad types of treatments for psychological disorders?
Psychological treatment: the client interacts with a clinician in order to use the environment to change their brain and behaviour
Biological treatment: drugs, surgery, or other types of interventions directly treat the brain
Define psychotherapy
an interaction between a socially sanctioned clinicians and someone suffering from a psychological problem, with the goal of providing support or relief from the problem
What is eclectic psychotherapy?
a form of psychotherapy that involves drawing on techniques from different forms of therapy, depending on the client and the problem
• Allows therapists to apply an appropriate theoretical perspective suited to the problem at hand
What are the top 5 orientations to psychotherapy?
Most to least popular:
- Cognitive behavioural
- Humanistic/existential
- Psychodynamic
- Interpersonal
- Family systems
What are psychodynamic psychotherapies?
explore childhood events and encourage individuals to use the understanding gained from the exploration to develop insight into their psychological problems
What are the underlying beliefs/assumptions of humanistic and existential therapies?
- A reaction to the negative views that psychoanalysis holds about human nature
- Assumes human nature is generally positive
- Emphasizes the natural tendency to strive for personal improvement
- Assumes psychological problems stem from alienation, loneliness, failure to reach one’s potential, and failure to find meaning in life
What is person-centred/client-centred therapy?
assumes that all individuals have a tendency towards growth and that this growth can be facilitated by acceptance by and genuine reactions from the therapist (Carl Rogers)
What is Gestalt therapy?
has the goal of helping the client become aware of their own thoughts, behaviours, experiences, and feelings and to “own” or take responsibility for them (Frederick Perls)
What is behaviour therapy?
assumes that disordered behaviour is learned and that symptom relief is achieved through changing overt, maladaptive behaviours into more constructive behaviours
• A variety of behaviour therapy techniques have been developed based on learning principles (operant conditioning, classical conditioning)
How does behaviour therapy approach eliminating unwanted behaviours?
- Investigating what happens immediately before and after the behaviour
- Understanding that behaviour can be influenced by its consequences, and that adjusting these can change the behaviour (operant conditioning)
How does the behaviour therapy approach promote desired behaviour?
Token economy: involves giving clients “tokens” for desired behaviours that they can later trade for rewards
How does behaviour therapy approach reducing unwanted emotional responses?
Exposure therapy: an approach to treatment of the client that involves confronting an emotion-arousing stimulus directly and repeatedly, ultimately leading to a decrease in the emotional response
-Depends on the processes of habituation and response extinction
What is cognitive therapy?
focuses on helping a client identify and correct any distorted thinking about self, others, or the world
Instead of pathology being the outcome of classical/operant conditioning, it is the outcome of a person’s interpretation of the event
What is cognitive restructuring?
teaches clients to question the automatic beliefs, assumptions, and predictions that often lead to negative emotions and to replace negative thinking with more realistic and positive beliefs; clients are taught to examine evidence for-against a particular belief or to be more accepting of outcomes that may be undesirable
What is cognitive-behavioural therapy, and what are its two main characteristics?
a blend of cognitive and behavioural therapeutic strategies
• Problem-focused (undertaken for specific problems)
• Action-oriented (the therapist tries to assist the client in selecting specific strategies that could help address those problems; client is required to do things like journaling, exposure exercises, behaviour-changing skill practice, etc.)
What are some advantages of group therapy?
- Attending a group with individuals who have similar problems shows clients that they are not alone in their suffering
- Group members model appropriate behaviours for each other and share their insights about how to deal with problems
- Often just as effective as individual therapy
What are some disadvantages of group therapy?
- May be difficult to assemble a group of individuals who have similar needs
- May become a problem if one or more members undermine the treatment of others group members (dominating discussions, threatening others, making others uncomfortable, having dual relationships with group members, etc.)
- Clients get less individualized attention
How did the original antipsychotic drugs support the dopamine hypothesis?
The drugs both block dopamine receptors and work to decrease positive symptoms of schizophrenia, suggesting schizophrenia is caused by excess dopamine
What is different about atypical antipsychotic medications?
Affect both the dopamine and serotonin systems; work well for both positive and negative symptoms
How do benzodiazepines work?
facilitate the action of the neurotransmitter GABA, which inhibits certain neurons in the brain and produces a calming effect
Why are doctors cautious when prescribing benzodiazepines?
- Potential for abuse
- Drug tolerance
- Risk of withdrawal symptoms
- Negative side effects
- Do not interact well with alcohol
What are the 4 common types of antidepressants?
MAOIs: prevent the enzyme monoamine oxidase from breaking down neurotransmitters
Tricyclic antidepressants: block the reuptake of norepinephrine and serotonin
SSRIs: block the reuptake of serotonin in the brain
SNRIs
What are the 3 illusions of psychological treatment?
- Natural improvement: the tendency of symptoms to return to their mean or average level; causes the patient to mistakenly conclude that a treatment has made them better even though it would have gotten better anyways
- Placebo effects: recovery that is the result of nonspecific treatment effects that are not related to the proposed active ingredient of the treatment; recovery may be attributed to the treatment, when in reality it was another factor (ex. simply believing you are getting a treatment)
- Reconstructive memory: thinking you have improved or believing that your symptoms were much worse before treatment;
“getting what you want by revising what you had”
What are the two levels of empirical support developed by the APA for psychological treatments?
Well-established treatments (those with a high level of support, such as evidence from several randomized controlled trials)
Probably efficacious treatments (those with preliminary support)
Define iatrogenic illness
a disorder or symptom that occurs as a result of a medical or psychotherapeutic treatment itself
May result from psychotherapy based in an incorrect diagnosis (being treated for a disorder causes symptoms of the disorder, even though the person didn’t have it in the first place), being influenced through hypnosis or repeated suggestion in therapy, “trading one symptom for another” with psychotropic medications, etc.
What 4 principles are ethical standards for psychotherapy based on in Canada?

- Responsible caring
- Integrity in relationships
- Responsibility to society
What is agoraphobia?
Social isolation secondary to a fear of panic
What are the 6 most common obsessive themes in OCD?
- Harm
- Contamination
- Sexuality
- Perfectionism
- Religion
- Loss of control
What are the two most effective treatments for OCD?
- Exposure therapy
- Deep brain stimulation
Which neurotransmitter(s) do MAOIs act on?
MAOIs inhibit the breakdown of norepinephrine, serotonin, and dopamine
Which neurotransmitter(s) do SSRIs act on?
SSRIs block the reuptake of serotonin
Which neurotransmitter(s) do SNRIs act on?
SNRIs block the reuptake of serotonin and norepinephrine
Which neurotransmitters do tricyclic antidepressants act on?
Tricyclic antidepressants block the reuptake of serotonin and norepinephrine
What are the two most effective treatments for bipolar disorder?
- Mood stabilizers (lithium, valproate)
- Electroconvulsive therapy
What are some structural changes in the brain associated with schizophrenia?
- Enlarged ventricles
- Progressive tissue loss
What are the names of some common antipsychotic medications?
- Zyprexa
- Seroquel
- Abilify
- Risperdal
What is labelling theory?
Criminologists theorize that labelling (conduct disorder, APD, etc.) increases further criminality
