CLINICAL- Anxiety disorders Flashcards
The 3 anxiety disorders are
- Generalized anxiety disorder
- Agoraphobia
- Specific phobia (blood injection phobia)
Describe Generalized anxiety disorder
- This is a long term- condition wherein feelings of anxiety may be on everyday events such as health, finances or family
symptoms are: - fear of losing control
- Nausea
- feeling dizzy or light headed
- sweating
Describe agoraphobia
- This is characterized by excessive fear in response to situations where escape may be difficult or help is unavailable such as:
- public transport
- crowded areas
- being outside home alone.
- Being in enclosed spaces
- The person is scared of having panic attacks or other embarrassing symptoms in a public place
Describe specific phobia
- This is characterized by excessive fear/ anxiety when exposed to or in anticipation of a specific stimulus
- The fear is usually disproportionate to the actual threat from the stimulus
- The symptoms can persist for several months and can impair important parts of functioning.
What are the 2 measures used for anxiety disorders
- The Generalized Anxiety Disorder 7 (GAD-7)
- The Blood Injection Phobia Inventory (BIPI)
Describe the GAD-7
- This is a questionnaire
- It has 7-items that measure the severity of anxiety. examples of items:
> feeling nervous
> being so restless its hard sit still
> feeling afraid as if something might happen . - Respondents are asked to provide a score between 0-3 for each item whereby it checks the frequency of their symptoms:
0= not at all
1=several days
2=more than half the days
3=nearly everyday
Describe the BIPI
- This is a self-report measure containing 18 possible situations involving blood and injections
- for each situation they are asked to evaluate different reactions they might experience for that situation.
- These include psychological, cognitive and behavioural
EXAMPLE SITUATION: When i see someone injured/bleeding on the road
EXAMPLE REACTIONS:
a) I wont bear the situation
b) I think I am going to faint
c) I think something bad is going to happen to me - The must rate on a scale 0-3 with 0- never and 3-always
What did Mas et al 2010 find about the BIPI
- he found the BIPI has excellent reliability and concurrent validity and was able to clearly discriminate between diagnosed with the phobia and those that werent.
Evaluate the GAD-7 and BIPI
- High concurrent validity
- Response bias due to self-report
- Reductionists as they rely on a single quantitative measurement of a complex patient experience.
- Cultural bias does not support non-western cultures due to medical procedures being rare
What does the Biological explanation suggest for this disorder
GENETICS:
- It suggests that we are born prepared to fear certain objects.
- There are stimuli in the environment that pose a threat to survival that we are genetically set up to avoid.
in Ost et al. Describe what the blood-phobic patients went through
- they watched a 30 mins silent colour video of surgery being performed
- They were told not to close their eyes but try to watch as long as they could
- the experimenter would track their gaze direction
- if the participant looked away or stopped the video, the test would end
in Ost et al. Describe what the injection- phobic patients went through
- This involved 20 steps from the individuals fingertip being cleaned to having a fingertip being pricked
- The steps were described to the patients and they were to say whether or not it was ok to perform
Describe the measures used in Ost et al.
- The measures recorded their maximal performance and rated their fainting behaviour (0-4)
- the patients would do a self-rating of anxiety (0-10)
- The patients were given another questionnaire on their thoughts and feelings during the tests
- Their blood pressure and heart rate were monitored
state one result found in Ost et al.
There was a higher proportion of the participants with blood phobia (70%) and injection phobia (56%) that had a history of fainting when exposed to their respective phobic stimuli compared to those with other specific phobias.
what did Ost et al. conclude
There seems to be a strong genetic link for these behaviours which are more likely for these phobias than other phobias to produce a strong physiological response (fainting)
Evaluate the biological explanation
- Supports nature
- Reductionist
- Deterministic
- Objective uses standardized behavioural tests and interviews with large groups
what does the Behavioural (psychological) explanation suggest about this disorder: Classical condition
- Classical conditioning: An individual may develop a phobia of a harmless stimulus if it is paired with a frightening stimulus. Future association with the neutral stimulus will produce a fearful conditioned response
- Watson and Rayner used the principles of classical conditioning to create a phobia in a young healthy 9-month-old infant ‘‘Little Albert’’
- little Albert was shown a variety of neutral stimuli such as a white rat, a rabbit, or a dog
- He was then exposed to the unconditioned stimulus which was the loud noise of a metal bar leading to an unconditioned response of fearful crying
- The experimenters combined Neutral stimulus + unconditioned stimulus and after conditioning it became a conditioned stimulus (white rat or anything similar) to bring out a conditioned response (fearful crying and avoidance)
what does the Behavioural (psychological) explanation suggest about this disorder: operant condition
- Operant conditioning is based on the principle of learning through consequences
- Negative reinforcement is the increased likelihood of repeating a behaviour due to the removal of something negative or unpleasant
- Negative reinforcement can explain how phobia persists
- The removal of the phobic stimulus reduces the fear and so acts as a reward and the avoidant will continue this behaviour
- This leads to a continuation of the phobia because, avoiding the stimulus completely, gives the avoidant no opportunity to see that there is little fear
what does the Psychodynamic (psychological) explanation suggest about this disorder
- A fear is repressed into the unconscious to protect the ego
- Freud suggested that phobias are a result of the id being denied/repressed during the psychosexual stages of development
- . Conflict is repressed into the unconscious
and the phobic object/situation symbolises this conflict. - Example study Little Hans
What had the father of Hans reported to Freud
- He believed that his fear of horses was due to their large penis
- He said that one dream he had was when he had several children with his mother and the father was the grandfather
- He also dreamed that a plumber came to cut his penis off and replace it with a larger one
- The Oedipus complex was further supported by the 2 fantasies which represented the dynamic of the 3-way relationship between Little Hans and his parents
Evaluate the Psychological explanation
- Supports nurture side
- Deterministic: If you are subject to conditioning where an association is made between a feared stimulus
- Ethical concerns were found in Little Albert as he was exposed to psychological harm however there was parental consent
- Both Little Hans and Albert were case studies, so they are not generalizable. However one could argue that Watson carried out a number of trials
- In-depth and qualitative research was carried out in Freud’s study which can help get a better understanding
What refers to systematic Desensitisation
- This is a way of reducing undesirable responses to a particular situation. It assumes that nearly all behavior is a conditional response to stimuli
- Wolpe et al. introduced the idea of reciprocal inhibition, which is the impossibility of 2 strong opposing emotions at the same time
- the aim is to put the fearful feelings associated with the phobic stimulus in conflict with feelings of calmness/relaxation.
What are the steps that systematic desensitization goes through:
1- The patient is first taught relaxation techniques such as progressive relaxation exercises or anti-anxiety drugs
2- The patient and therapist will then work together to create an anxiety hierarchy which is a list of anxiety-provoking situations that increase in severity. They will depend on whether they are working with in vitro or in vivo exposure to each stage.
3- At each stage of the hierarchy, they will be required to remain calm using the different techniques learned. The patient cannot move to the next level in the hierarchy unless they report no feeling of anxiety in their current stage
How does CBT treat anxiety disorders
- They work by challenging their irrational thoughts
- Next, replace them with more rational ones
- The rational thinking leads to changes in behavioral and emotional response until the phobia is treated.
