Behavioural Approach to TREATING phobias Flashcards
What is Systematic Desensitisation, its AIMS π― and how does it work?
- Systematic Desensitisation (SD) is a behavioural πͺπΌ therapy designed to gradually reduce phobic π£ anxiety through the principle of CC.
If the sufferer can learn to relax π 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 π and relaxed π@ same time, 1οΈβ£ emotion prevents the other.
There are 2 types of SD:
> In-vivo- where individual is exposed π΅ to the actual object/situation
> In-vitro - where individual imagines π being exposed to the phobic object/ situation.
How many and what processes are involved in SD?
1) Relaxation π
2) The anxiety π£ hierarchy πΊ
3) Exposure π΅
What is the process of RELAXATION π in SD
The therapist π©π»βπ« teaches patient ππΌto relax as deeply as possible. i.e. might involve breathing exercises π, 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 π and gain composure in variety of situations or alternatively the patient might learn mental imaginary π techniques.
Patients can be taught to imagine π themselves in relaxing π situations (lying on the beach π ) or might learn mediation π€Έπ»ββοΈ.
What is the process of THE ANXIETY HIERARCHY π£πΊin SD
The anxiety hierarchy π£πΊis put together by the client ππΌ and therapistπ©π»βπ«.
It a list πof situations related to the phobia that provoke anxiety arranged in order from least πto most frighteningπ.
E.g. a spider π·phobic might identify seeing an image πΌ of a small spider as low β¬οΈ on their anxiety hierarchy and holding a tarantulaβπΌπ· at the top π of the hierarchy.
What is the process of EXPOSURE π΅ in SD
The patient is then exposed π΅to the phobic stimulus while in a relaxed π state.
This takes place across several sessions, starting at bottom β¬οΈ of the anxiety hierarchy.
When the patient can stay relaxed π in the presence of the lower β¬οΈ levels of the phobic stimulus they move up π the hierarchy.
Treatment is successful ππΌ when the patientπ©πΌcan stay relaxed π in situations high πon the anxiety hierarchy π£πΊ.
What are the evaluation points of SD in terms of its EFFECTIVENESS?
1) It is effective β
2) Relaxation π may not be necessary (placebo effect) βοΈ
Outline the evaluation point
1) It is effective β in terms of effectiveness
Point:
Strength πͺπΌ of SD for the treatment of phobias is that research π¬ shows that its effective in the treatment for specific phobias.
E:
Gilroy et al 2οΈβ£0οΈβ£0οΈβ£3οΈβ£ followed up π©π»βπΌx42 patients who had been treated for spider π· trauma in 3, 45 minute β± sessions of SD. A control group was treated by relaxation πwithout π«exposure π΅to spidersπ·
@ both 3 and 33 months after the treatment the SD group were less fearful than the relaxation group.
Additionally, McGrath et al 1οΈβ£9οΈβ£9οΈβ£0οΈβ£reported that 75% of clients π©π»βπΌ with phobias responded to SD.
According to Choy et al 2οΈβ£0οΈβ£0οΈβ£7οΈβ£ the key π to success lies with the actual contact with the feared stimulus, so IN-VIVO techniques are more successful than ones using images πΌ or imagining π 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 π may not be necessary π« (placebo effect) βοΈ in terms of EFFECTIVENESS
Point:
Weakness βοΈ is that it may be that the success is more to do with exposure π΅ to the feared situation than relaxation π.
Explain:
It might be that the expectation of being able to cope with the feared stimulus is important.
Example:
Klein et al 1οΈβ£9οΈβ£8οΈβ£3οΈβ£ 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 βactive ingredientβ 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 π for many clients π©π»βπΌ β
4) Symptom substitution βοΈ
Outline the evaluation point
3) More preferable to flooding π for many clients π©π»βπΌ β in terms of APPROPRIATENESS
Point:
Strength β
of SD is that patients π©π»βπΌ seem to prefer it to flooding π because they feel that it is less traumatic because of the more gentle π step by step approach.
Explain:
Largely because it doesnβt cause the same degree of trauma as flooding π - due to slowly working through the anxiety hierarchy is seen more ethical π.
Elaborate:
This is reflected in the low refusal rates (NO. of pβs refusing π
πΌββοΈ to start treatment) and low attribution rates (pβs 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 βοΈ in terms of APPROPRIATENESS
Point:
Limitation βοΈ of SD as treatment for phobias is that the psychodynamic model claims that SD ( & other behavioural therapies e.g. flooding π) focuses only on symptoms & ignores the cause of abnormal π½ behaviour.
Explain:
Psychoanalysts π©π»ββοΈ claim that symptoms are merely the tip of the iceberg π- the outward expression of deeper underlying emotional problems.
Elaborate:
Psychoanalysts π©π»ββοΈ 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 π« this criticism and claim that we need to not look beyond the behavioural symptoms as the symptoms are the disorder.
What is flooding π and the aim π― of it?
The aim π― of flooding π is to exposeπ΅ the suffererπ· to the phobic object or situation for an extended period of time in a safe and controlled environment.
What does flooding π include?
- Immediate exposure π΅ to the phobic stimulus
- Exhaustion π€π of phobic response
- Prevention π«of avoidance
What does it mean to Immediately π΅ expose the phobic stimulus?
Involves bombarding βοΈ the phobic patient π· 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 π· phobia (arachnophobia) receiving flooding π treatment may have large spider crawl over their hand βπΌπ·until they can fully relaxπ. As a result, flooding πsessions are longerβ± 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 π€πof phobic response?
Means that flooding π is without the option of avoidance π« behaviour, the patient π©π»βπΌ 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 π©π»βπΌ might even achieve relaxation π in presence of phobic stimulus simply because they become exhausted π€π of their own fear response.
What does it mean by Prevention π« of avoidance?
Avoidance π« behaviours maintain the phobia as the phobic π·cannot learn that the thing they fear is not harmful.
So stopping the phobic π· patient from making their usual avoidance π« responses is necessary to prevent reinforcement of the phobia.
Ethical π safeguards
Flooding π is not unethical, but it is an π© unpleasant experience so it is important that patients π©π»βπΌ give informed consent π.
They must be fully prepared and know what to expect .
Before exposure, the client might be trained in relaxation π techniques so that they are best able to control their fearful responses.
What are the evaluation points of flooding as a behavioural approach to treating phobias as an EFFECTIVENESS?
1) Effectiveness β
2) It is less effective for social phobia βοΈ
Outline the evaluation point
1) Effectiveness in terms of effectiveness β
Point:
Strength β
of flooding π as a treatment for phobias is that it appears to be an effective treatment and it is relatively quick (compared to Cognitive Behavioural Therapy).
Example:
Wolpe 1οΈβ£9οΈβ£7οΈβ£3οΈβ£ took a girl π±πΌββοΈ who was scared of cars π , and drove her around for hours π. Initially the girl π±πΌββοΈwas hysterical π©but she eventually calmed π down when she realised π§that her situation was safe. From then on she associated a sense of ease with cars.
Elaborate:
Also in comparison to SD, Choy et al 2οΈβ£0οΈβ£0οΈβ£7οΈβ£ reported that flooding π was the more effective of the two at treating phobias.
Re-cap:
The fact that flooding π is a quick treatment for phobias is also a strength β
because it means that patients are free of their symptoms faster and that makes the treatment cheaper π΅.
Outline the evaluation point
2) It is less effective for social phobia in terms of effectiveness βοΈ
Point:
Limitation βοΈ of flooding π as a treatment for phobias is that although flooding is highly effective for treating simple phobias it appears to be less so far more complex phobias like social phobias.
Explain:
This may be because social phobias have cognitive aspects.
Example:
E.g. a sufferer π· of a social phobia does not simply experience an anxiety response but thinks unpleasant thoughts about the social situation.
Elaborate:
This type of phobia may benefit more from cognitive therapies because such therapies tackle the irrational ππΌ π thinking.
Re-cap:
This suggests that the effectiveness of flooding π as a method of treating phobias is more dependent on the type of phobia.
What are the evaluation points of flooding π as a behavioural approach to treating phobias as APPROPRIATENESS ?
3) The treatment can be traumatic for patients βοΈ
4) Symptom substitution βοΈ
Outline the evaluation point
3) The treatment can be traumatic for patients βοΈ in terms of APPROPRIATENESS
Point:
Limitation βοΈ of flooding π as a treatment for phobias is that it can be a highly traumatic experience.
Explain:
It is important that a cost-benefit analysis is carried out before engaging with flooding π as it can be psychologically harmful (although the cost-benefit analyses may regard the long term benefits of getting rid of the phobia as outweighing the short term costs of distress).
Elaborate:
Flooding π is not unethical π (patients π©π»βπΌmust give fully informed consentπ and they must be fully prepared before the session), however, it might be viewed to be too traumatic for children π§π»π¦πΌ, and they may not be able to fully understand what they are consenting too.
Re-cap:
Additionally, many patients π©π»βπΌ who start with flooding π are unwilling to see it through to the end, which is a limitation βοΈof flooding πbecause time β±and money π° may be wasted preparing patients only to have them refuse to start or complete treatment.
Outline the evaluation point
4) Symptom substitution βοΈ in terms of APPROPRIATENESS
Point:
Limitation βοΈof flooding π as a treatment for phobias is that the psychodynamic model claims that flooding π (and the other behavioural therapies in general e.g. SD) focuses only on symptoms and ignores the causes of abnormal behaviour.
Explain:
Psychoanalysts π©π»βπΌclaim that the symptoms are merely the tip of the iceberg π- the outward expression of deeper underlying emotional problems.
Elaborate:
Psychoanalysts π©π»βπΌbelieve that whenever symptoms are treated without any attempt to work out the deeper underlying problems, then the problem will only show itself in another way, through different symptoms - known as symptom substitution.
Re-cap:
Behaviourists however reject this criticism and claim that we need not look beyond the behavioural symptoms as the symptoms are the disorder.
