Q

Describe the GAD-7

A
  • 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

Q

Describe the BIPI

A
  • 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

Q

Evaluate the GAD-7 and BIPI

A
  • 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 (western culture)

Q

What does the Biological explanation suggest for this disorder

A

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.

Q

in Ost et al. Describe what the blood-phobic patients went through

A
  • 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

Q

in Ost et al. Describe what the injection- phobic patients went through

A
  • 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

Q

Describe the measures used in Ost et al.

A
  • 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

Q

state one result found in Ost et al.

A

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.

Q

what did Ost et al. conclude

A

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)

16
Q

Evaluate the biological explanation

A
  • Supports nature
  • Reductionist
  • Deterministic
  • Objective uses standardized behavioural tests and interviews with large groups
17
Q

what does the Behavioural (psychological) explanation suggest about this disorder: Classical condition

A
  • 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)
18
Q

what does the Behavioural (psychological) explanation suggest about this disorder: operant condition

A
  • 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
19
Q

what does the Psychodynamic (psychological) explanation suggest about this disorder

A
  • 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
20
Q

What had the father of Hans reported to Freud

A
  • 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
21
Q

Evaluate the Psychological explanation

A
  • 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
22
Q

What refers to systematic Desensitisation

A
  • 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.
23
Q

What are the steps that systematic desensitization goes through:

A

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

24
Q

How does CBT treat anxiety disorders

A
  • 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.
25
Q

What were the main theories and explanations in Chapman and Delapp

A
  • CBT is an effective treatment for a range of phobias as it enables the individual to challenge their irrational thoughts and replace them with more rational ones
  • this form of CBT involves applying tension. Because fainting is a result of lowered blood pressure, the therapy aims to reduce instances of fainting and other unpleasant responses by applying tension to the muscles
26
Q

Evaluate the psychodynamic explanation

A
  • There is no empirical evidence to support the explanation
  • Case study has low generalizability
  • Han’s father provided the correspondence so could have been biased in information to fit the theory
  • Use of longitudinal study allowed detailed collection
  • Deterministic, unresolved conflict leads to fear and anxiety and individuals have no control over this development
27
Q

Evaluate systematic desensitzation

A
  • Supports nurture as some phobias come from traumatic events
  • Time-consuming to learn relaxation and move down the hierarchy
  • Applicable as once they have learned it, they can apply it away from therapy
  • Individualistic as individual differences may happen
  • Reductionist only focuses on negative associations
  • Free will as it is up to the patient to decide to go through therapy
28
Q

Describe how applied tension for blood/injection phobia works

A
  • This works by applying tension to the muscles to increase blood pressure throughout certain areas in the brain as blood phobia is associated with a drop in blood pressure and fainting
29
Q

What is the aim in Chapman

A
  • They want to investigate whether BII phobia can be successfully treated by CBT and applied tension
30
Q

Describe the sample

A
  • One participant
  • Male
  • 42 year old
  • diagnosed with BII phobia
  • referred to as “T’’ throughout the study
31
Q

List the 5 measures used in the study by Chapman

A
  • Beck Anxiety Inventory (BAI
  • Beck Depression Inventory (BDI)
  • The Quality of Life Satisfaction Questionnaire (Q-LES-Q)
  • The Blood Injection Symptom Scale (BISS)
  • Subjective Unit of Discomfort Scale (SUDS)
32
Q

What were the results of the interview about T’s history with anxiety

A
  • He witnessed several deaths of family members
  • he lived with a highly anxious grandmother who used a scanner to listen to emergency dispatch calls throughout
  • he witnessed other family members faint during medical procedures
33
Q

What was the Procedure in Chapman

A
  • T underwent 9 CBT sessions and applied muscle tension
  • During CBT, T was educated about common phobias and created a fear hierarchy
  • He then took the SUDS and gave his ratings of anxiety (0-100) at different stages of the hierarchy exposure
34
Q

What were the results BEFORE the treatment

A
  • T’s self assessments showed he and severe anxiety
  • minimal depressive symptoms
  • Overall good health
  • showed intense fear/anxiety surrounding blood and injections
35
Q

What were the results at the 4, 10 and 12 month post-treatment

A
  • It showed that his anxiety levels had significantly dropped and he no longer showed fear to medical-related stimuli
36
Q

What did Chapman conclude

A
  • CBT and applied muscle tension are effective treatments to BII phobia
37
Q

Evaluate Chapman

A
  • Case studies gives detailed understanding of their background and the cause of the phobia
  • Quantitative data was provided
  • detailed interviews for qualitative analysis
  • Applicable to everyday life
  • Lack of generalizability
  • A case study cannot be replicated
  • Self reports lack validity due to social desirability and subjective interpretation
