Behavioural approach to treating phobias Flashcards
What are the two behavioural methods used in the treatment of phobias?
- systematic desensitisation
- flooding
What is systematic desensitisation?
- a behaviour therapy designed to gradually reduce phobic anxiety through the principle of classical conditioning
- phobic stimulus is paired with relaxation instead of anxiety- counter conditioning
What is the first process of SD and explain it?
1) anxiety hierarchy - client & therapist put this together in which objects/stressful events are placed from least to most frightening
E.g. photo of dog=least
proximity to dog=most
What is the second process of SD and explain it?
2) Relaxation - client is taught relaxation techniques e.g. breathing exercises, meditation or drugs etc
- fear and relaxation can’t co-exist, so one emotion prevents the other -this is called reciprocal inhibition
What is the last process of SD and explain it?
3) Exposure- client is exposed to phobic stimulus in relaxed state over several sessions
- starts at the bottom of hierarchy and gradually makes way up each time they are relaxed in a level of the hierarchy
What is flooding?
- A behavioural therapy in which a person with a phobia is exposed to extreme from of phobic stimulus immediately without a gradual build up
- important client gives informed consent >unpleasant
Why does flooding stop phobic responses qucikly?
- client has no option of avoidance so they quickly learn that the phobic stimulus is harmless - this process known as extinction
- extinction occurs when CS (e.g. dog) is encountered without UCS (e.g. being bitten)
result= CS no longer produces CR (fear)
What is a strength of SD as a treatment for phobias?
- evidence for its effectiveness
- Gilroy et al followed up 42 people who had SD for spider phobia
- At both 3 & 33 months the SD group were less fearful than control group treated by relaxation without exposure
- others researchers have also concluded that SD is effective for specific, social & agoraphobias
- increased reliability
What is another strength of SD in terms of appropriateness?
- can be used to treat people with learning disabilities
- alternatives to SD are not suitable
- people with learning disabilities often struggle with cognitive therapies that require complex rational thought
- flooding also too traumatic for them
- flooding = most appropriate treatment for those with LD who have phobias
What is a strength of flooding?
- highly cost and clinically effective
- flooding can work in as little as one session opposed to ten sessions for SD to achieve the same results
- NHS can treat more people at the same costs
- increases value of flooding as treatment
What is a limitation of flooding?
- highly unpleasant experience
- confronting ones phobic stimulus in extreme form provokes tremendous anxiety
- researchers found that p’s & therapists rated flooding as significantly more stressful than SD
- raises ethical issues for psychologists of knowingly causing stress to their clients
- Moreover, traumatic nature of flooding =higher drop out rates than SD
