Lesson 7 - Behavioural Treatments for Phobias Flashcards
Systematic Desensitisation
Behavioural therapy developed by Wolfe (1958) to reduce phobias using classical conditioning
A person experiences fear and anxiety as a behavioural response to a phobic object
SD replaces fear/anxiety with relaxed response instead
Central idea of SD is that it is impossible to experience two opposite emotions at the same time - Reciprocal Inhibition
Therefore, if patient can learn to remain relaxed in presence of phobia, it can be cured - Counter Conditioning
Stages of Systematic Desensitisation
Anxiety Hierarchy
Relaxation Training
Gradual Exposure
Stages of Systematic Desensitisation
Anxiety Hierarchy
Therapist and patient construct hierarchy of fear
Situations involving phobic object are ranked from least fearful to most fearful
Stages of Systematic Desensitisation
Relaxation Training
Patients are taught deep muscle relaxation techniques such as progressive muscular relaxation (PMR) and the relaxation response
Idea is to tense up a gourd of muscles as tightly contracted as possible, hold them in state of extreme tension then relax
Finally consciously relax muscles further so patient is as relaxed as can be
Stages of Systematic Desensitisation
Gradual Exposure
Patient is introduced to phobic object and they work their way up hierarchy of fear
Use relaxation techniques until fully comfortable and then move on up to next stage
Eventually phobia is eliminated
Systematic Desensitisation Evaluation
Jones (1924)
Positive
Supports use of SD to eradicate Little Peter’s phobia of a white rabbit
Eventually developed affection for rabbit
Systematic Desensitisation Evaluation
Klosko et al. (1990)
Positive
Supports use of SD
Assessed various therapies for treatment of panic disorders cant found 87% were panic free after receiving SD compared to 50% on medication, 36% on placebo and 33% with no treatment
Systematic Desensitisation Evaluation
Underlying Causes
Negative
Behavioural therapies address symptoms of phobias
Critics believe symptoms are merely the tip if the iceberg and claim underlying causes remain
Future symptoms will return or symptom substitution will occur
Flooding
Direct exposure of patient to phobic object
Patient is taught relaxation techniques such as deep muscle relaxation, deep breathing and meditation
No gradual build up
Immediate exposure to a very frightening and extreme situation
Stops phobic responses quickly as patient has no option for avoidance - learn object is harmless (extinction occurs)
Ethical but causes psychological harm but has informed consent
Flooding Evaluation
Wolfe (1960)
Positive
Supports use of flooding to remove patient’s phobias of being in cars
A girl was forced into a car and driven around for four hours until her hysteria was eradicated
Demonstrates how effective flooding is as a treatment for phobias
Flooding Evaluation
Trauma
Negative
Highly traumatic experience and some patients may be unwilling to continue with therapy to the end
Time and money will be wasted for preparation and then patient might decide they do not want to take part or complete treatment
Phobia remains uncured
Behavioural Treatments for Phobias Evaluation Points
