patients are given immediate exposure to a frightening situation
flooding stops phobic responses very quickly
removes the option of avoidance behaviour so the patient quickly learns that the stimulus is harmless (this is known as extinction in classical conditioning)
it is an unpleasant experience so patients must give full informed consent before the procedure
A learned response is extinguished if the CS (e.g. a dog) is encountered without the UCS (being bitten)
2. Systematic desensitisation
developed by Wolpe (1950s)
based on the principle of counter-conditioning (learning a response)
aims to reduce an undesirable behaviour e.g. fear/anxiety with a more desirable one e.g. relaxation
Stages involved in systematic desensitisation (anxiety hierarchy)
Patient is taught relaxation techniques
Patient and therapist construct an anxiety hierarchy - a series of imagined scenes, each one causing a little more anxiety than the previous one~
Patient visualises the first stage in the hierarchy whilst engaging in the relaxation response at the same time
Once a stage of the hierarchy has been mastered, they move onto the next stage
Patient eventually masters the most feared situation
Systematic desensitisation: strength
Research shows SD works for a variety of anxiety disorders
Evidence: 75% of patients with a range of phobias reported that SD had helped where as 33% of patients with a similar range of phobias reported that the drug treatments had helped.
This suggests it is more effective than drugtreatments for phobias
Systematic desensitisation: strength
Quick and requires less effort than other psychotherapies
This means that patients are more likely to continue with the treatment, making it more likely to succeed.
This suggests that SD may be more appropriate than other therapies.
Systematic desensitisation: limitation
SD works better with phobias that have been acquired through personal experience rather than phobias like fear of heights.
This means we may be biologically prepared to have a fear of certain animals/situations - it may be an evolutionary survival strategy.
This means that SD has limited effectiveness for treating our phobias.
Systematic desensitisation: limitation
treats the symptoms, not the causes
if the cause of the problem is not treated, the symptoms may resurface as a different phobia.
this means that SD is not always completely effective.
Flooding: strength
cost effective
comparisons to other therapies show that it is highly effective and quicker than alternatives
free of symptoms sooner, treatment becomes cheaper
Flooding: limitation
not effective for all phobias
not as effective for complex phobias possibly due to the fact that they have a cognitive component
this means it has limited effectiveness as it cannot be used for all phobias
