Behavioural Approach to TREATING phobias Flashcards
What is Systematic Desensitisation, its AIMS ๐ฏ and how does it work?
- Systematic Desensitisation (SD) is a behavioural ๐ช๐ผ therapy designed to gradually reduce phobic ๐ฃ anxiety through the principle of CC.
If the sufferer can learn to relax ๐ in the presence of the phobic stimulus then a new response (relaxation instead of anxiety) is learned and the phobia is cured.
The learning of a new response is called counter-conditioning. So SD aims to replace faulty association between the CS and the CR that has resulted in a phobic response.
- Its impossible to be afraid ๐ and relaxed ๐@ same time, 1๏ธโฃ emotion prevents the other.
There are 2 types of SD:
> In-vivo- where individual is exposed ๐ต to the actual object/situation
> In-vitro - where individual imagines ๐ญ being exposed to the phobic object/ situation.
How many and what processes are involved in SD?
1) Relaxation ๐
2) The anxiety ๐ฃ hierarchy ๐บ
3) Exposure ๐ต
What is the process of RELAXATION ๐ in SD
The therapist ๐ฉ๐ปโ๐ซ teaches patient ๐๐ผto relax as deeply as possible. i.e. might involve breathing exercises ๐, e.g. may be taught the 7/11 technique, where you breathe in for a count of 7 and out for 11.
Its used to help people relax ๐ and gain composure in variety of situations or alternatively the patient might learn mental imaginary ๐ญ techniques.
Patients can be taught to imagine ๐ญ themselves in relaxing ๐ situations (lying on the beach ๐ ) or might learn mediation ๐คธ๐ปโโ๏ธ.
What is the process of THE ANXIETY HIERARCHY ๐ฃ๐บin SD
The anxiety hierarchy ๐ฃ๐บis put together by the client ๐๐ผ and therapist๐ฉ๐ปโ๐ซ.
It a list ๐of situations related to the phobia that provoke anxiety arranged in order from least ๐to most frightening๐.
E.g. a spider ๐ทphobic might identify seeing an image ๐ผ of a small spider as low โฌ๏ธ on their anxiety hierarchy and holding a tarantulaโ๐ผ๐ท at the top ๐ of the hierarchy.
What is the process of EXPOSURE ๐ต in SD
The patient is then exposed ๐ตto the phobic stimulus while in a relaxed ๐ state.
This takes place across several sessions, starting at bottom โฌ๏ธ of the anxiety hierarchy.
When the patient can stay relaxed ๐ in the presence of the lower โฌ๏ธ levels of the phobic stimulus they move up ๐ the hierarchy.
Treatment is successful ๐๐ผ when the patient๐ฉ๐ผcan stay relaxed ๐ in situations high ๐on the anxiety hierarchy ๐ฃ๐บ.
What are the evaluation points of SD in terms of its EFFECTIVENESS?
1) It is effective โ
2) Relaxation ๐ may not be necessary (placebo effect) โ๏ธ
Outline the evaluation point
1) It is effective โ in terms of effectiveness
Point:
Strength ๐ช๐ผ of SD for the treatment of phobias is that research ๐ฌ shows that its effective in the treatment for specific phobias.
E:
Gilroy et al 2๏ธโฃ0๏ธโฃ0๏ธโฃ3๏ธโฃ followed up ๐ฉ๐ปโ๐ผx42 patients who had been treated for spider ๐ท trauma in 3, 45 minute โฑ sessions of SD. A control group was treated by relaxation ๐without ๐ซexposure ๐ตto spiders๐ท
@ both 3 and 33 months after the treatment the SD group were less fearful than the relaxation group.
Additionally, McGrath et al 1๏ธโฃ9๏ธโฃ9๏ธโฃ0๏ธโฃreported that 75% of clients ๐ฉ๐ปโ๐ผ with phobias responded to SD.
According to Choy et al 2๏ธโฃ0๏ธโฃ0๏ธโฃ7๏ธโฃ the key ๐ to success lies with the actual contact with the feared stimulus, so IN-VIVO techniques are more successful than ones using images ๐ผ or imagining ๐ญ the feared stimulus (IN-VITRO).
Re-cap:
These pieces of research demonstrate that SD is a useful technique in the treatment of specific phobias.
Outline the evaluation point
2) Relaxation ๐ may not be necessary ๐ซ (placebo effect) โ๏ธ in terms of EFFECTIVENESS
Point:
Weakness โ๏ธ is that it may be that the success is more to do with exposure ๐ต to the feared situation than relaxation ๐.
Explain:
It might be that the expectation of being able to cope with the feared stimulus is important.
Example:
Klein et al 1๏ธโฃ9๏ธโฃ8๏ธโฃ3๏ธโฃ compared SD with supportive psychotherapy (therapy that combines psychodynamic and cognitive therapies) for patients with specific or social phobias.
Elaborate:
They found no difference in the effectiveness, suggesting that the โactive ingredientโ in SD may simply be the generation of hopeful expectancies that the phobia can be overcome.
Re-cap:
Suggests the exact reason why SD is effective remains unclear.
What are the evaluation points of SD in terms of its APPROPRIATENESS ?
3) More preferable to flooding ๐ for many clients ๐ฉ๐ปโ๐ผ โ
4) Symptom substitution โ๏ธ
Outline the evaluation point
3) More preferable to flooding ๐ for many clients ๐ฉ๐ปโ๐ผ โ in terms of APPROPRIATENESS
Point:
Strength โ
of SD is that patients ๐ฉ๐ปโ๐ผ seem to prefer it to flooding ๐ because they feel that it is less traumatic because of the more gentle ๐ step by step approach.
Explain:
Largely because it doesnโt cause the same degree of trauma as flooding ๐ - due to slowly working through the anxiety hierarchy is seen more ethical ๐.
Elaborate:
This is reflected in the low refusal rates (NO. of pโs refusing ๐
๐ผโโ๏ธ to start treatment) and low attribution rates (pโs dropping out of treatment) of SD.
Re-cap:
Suggests that for many clients with phobias, SD is an appropriate treatment.
Outline the evaluation point
4) Symptom substitution โ๏ธ in terms of APPROPRIATENESS
Point:
Limitation โ๏ธ of SD as treatment for phobias is that the psychodynamic model claims that SD ( & other behavioural therapies e.g. flooding ๐) focuses only on symptoms & ignores the cause of abnormal ๐ฝ behaviour.
Explain:
Psychoanalysts ๐ฉ๐ปโโ๏ธ claim that symptoms are merely the tip of the iceberg ๐- the outward expression of deeper underlying emotional problems.
Elaborate:
Psychoanalysts ๐ฉ๐ปโโ๏ธ believe that whenever symptoms are treated without any attempt to work out the deeper underlying problems, the problem will only show itself in another way, through different symptoms - known as SYMPTOM SUBSTITUTION.
Re-cap:
Behaviourists however reject ๐ซ this criticism and claim that we need to not look beyond the behavioural symptoms as the symptoms are the disorder.
What is flooding ๐ and the aim ๐ฏ of it?
The aim ๐ฏ of flooding ๐ is to expose๐ต the sufferer๐ท to the phobic object or situation for an extended period of time in a safe and controlled environment.
What does flooding ๐ include?
- Immediate exposure ๐ต to the phobic stimulus
- Exhaustion ๐ค๐ of phobic response
- Prevention ๐ซof avoidance
What does it mean to Immediately ๐ต expose the phobic stimulus?
Involves bombarding โ๏ธ the phobic patient ๐ท with the phobic object (IN-VIVO exposure) until the person is calm and does not fear the stimulus, without a gradual build up.
So a spider ๐ท phobia (arachnophobia) receiving flooding ๐ treatment may have large spider crawl over their hand โ๐ผ๐ทuntil they can fully relax๐. As a result, flooding ๐sessions are longerโฑ than SD and last for 2-3 hours. Sometimes only 1 long session is required to cure the phobia.
What does it mean by Exhaustion ๐ค๐of phobic response?
Means that flooding ๐ is without the option of avoidance ๐ซ behaviour, the patient ๐ฉ๐ปโ๐ผ quickly learns that the phobic object is harmless through the exhaustion of their fear response - aka extinction.
In CC terms, the result is that the CS (spider) no longer produces the CR (fear).
In some cases patient ๐ฉ๐ปโ๐ผ might even achieve relaxation ๐ in presence of phobic stimulus simply because they become exhausted ๐ค๐ of their own fear response.
