systematic desensitisation is the behavioural therapy designed to gradually reduce phobic activity - through using principles of classical conditioning (association)
when sufferer can learn to associate relaxation with stimulus it means their phobia will be cured - new response then learned (phobic stimulus paired with relaxation rather than anxiety)
learning of new response - counterconditioning
reciprocal inhibition - impossible to be afraid and relaxed at same time - one emotion prevents the other
3 processes involved in systematic desensitisation
anxiety hierarchy - list of situations put together by patient and therapist showing least frightening to most frightening situations
relaxation - therapist teaches patient to relax deeply as possible (relaxation methods) - drugs are alternative to relax
exposure - patient then exposed to stimulus whilst in relaxed state - start off at bottom of hierarchy then move up
systematic desensitisation treatment seen as successful when patients can stay in relaxed state throughout all situations on anxiety hierarchy
evaluation for systematic desensitisation as treatment for phobias
effective (+)
suitable for diverse range of patients (+)
largely accepted by patients (+)
effective (+) as eval point for SD as treatment for phobias
therapy used within SD is seen to be effective
example - supporting research looked at 42 patients who were treated for spider phobias using SD compared with control group who was treated with relaxation but NO exposure
findings found after 3 months and 33 months after treatment - SD group were less fearful than relaxation group (control)
research support shows SD is helpful as long lasting + effective treatment of specific phobias
suitable for diverse range of patients (+) as eval point for SD as treatment for phobias
strength of SD is that treatment is suitable for wide range of patients
some alternative treatments like flooding aren't suitable for all patients
however - SD works well on ranges of individuals and therefore is seen as appropriate treatment for many individuals
largely accepted by patients (+) as eval point for SD as treatment of phobias
patients prefer SD as wat to treat phobias as result of it not causing the same level of trauma as opposed to alternative such as flooding
preference has been shown through low refusal rates and low attrition rates (most tend to finish full treatment rather than dropping out)
flooding is a form of treatment used to expose phobic patients to phobic stimulus with immediate exposure to frightening situation
flooding sessions tend to take longer than SD sessions (2-3 hours)
however sometimes only 1 session is needed to cure phobia
flooding works by stopping phobic stimulus responses very quickly
extinction - without option of avoidance behaviour the patient learns phobic stimulus isn't harmful
learned response is extinguished when conditioned stimulus is encountered without unconditioned stimulus - resulting in conditioned stimulus no longer producing conditional response (fear)
following is not unethical but it is an unpleasant experience - essential patients give informed consent + fully prepared for session
evaluation for flooding as treatment for phobias
traumatic for patients (-)
cost effective (+)
less effective for some types of phobias (-)
traumatic for patients (-) as eval point for flooding as treatment
due to instant exposure - flooding is highly traumatic experience
although patients give full consent - most wont see it through to end due to traumatic
as result - money and time is wasted as result of preparing patients only for them to refuse the start treatment or stop continuation
limitation as further therapy may be needed as result fo trauma as well as having negative effect on economy - money being used and 'wasted'
cost effective (+) as eval point for flooding as treatment for phobias
flooding seen as cost effective when compared with alternative treatments for phobias
only needed a few flooding sessions to treat phobias - found flooding is effective as well as quicker than alternatives
strength as phobia can be treated within few sessions compared to SD were multiple sessions are needed for gradual process
makes flooding cost effective if treatment is followed to end - positive impact on health system
less effective for some types of phobias (-) as eval point for flooding
flooding seen to be effective for treating simple phobias but is less effective for more complex - social phobias
may be because social phobias have cognitive aspects so are more likely to benefit from cognitive therapies
limitation as it restricts who has access to this form as way to treat their phobias
