1. Step 1: Teaching the client relaxation techniques
2. Step 2: Constructing an individual anxiety hierarchy
3. Step 3: Bringing relaxation techniques and anxiety hierarchy together
Step 1 of SD
Teaching the client a range of relaxation techniques to establish a new stimulus-response link to the phobic object
Counter-conditioning
The client learns a new, more adaptive association which replaces the old maladaptive response
Reciprocal inhibition
The relaxation inhibits (prevents) the anxiety
Step 2 of SD
Constructing an individual anxiety hierarchy starting with the least feared scenario and working towards the most feared scenario
In-vivo desensitisation
The client confronts the phobic object or situation in real life
In-vitro desensitisation
The client is asked to ‘imagine’ the phobic object or situation
Step 3 of SD
Bringing the relaxation techniques and anxiety hierarchy together and working up the anxiety hierarchy from least to most anxiety-provoking step
Systematic desensitisation is only complete when
The process of classical conditioning has been successful and the client is able to reach the top step of the anxiety hierarchy
Unlearning process
The client has unlearnt the maladaptive response to the feared object/situation (fear) and replaced it with the more adaptive learned response of calm and relaxation
Counter-conditioning
The process of replacing the maladaptive response with a more adaptive response
The behaviourist approach
Assumes that the underlying cause of all normal behaviour is through learning (conditioning)
Classical conditioning
New behaviour is learnt through a process of association, whereby an unconditioned stimulus becomes associated with a neutral stimulus, learning the same response to both
Operant conditioning assumption
Behaviour is learned through reinforcement
The behaviourist approach
Assumes that the cause of abnormal behaviour is a result of maladaptive faulty learning
Classical conditioning
Individual will actively avoid situations whereby they may be exposed to the phobic object (spider)
Avoidance acts as a reinforcement
They feel calm and happy when avoiding the spider
Systematic desensitisation
Aims to break down faulty maladaptive learning and help the person re-learn a more functional response using the principles of classical conditioning
Systematic desensitisation
Aims to gradually and systematically break down the faulty association (i.e. fear) and replace it with a more functional response (relaxation), known as counter-conditioning
Operant conditioning
Key to this therapy as the client progresses through an anxiety hierarchy, feeling more and more relaxed in the presence of the phobic object (e.g. a spider), which becomes reinforcing
Positive reinforcement
Encourages the client to keep moving up the hierarchy until they no longer associate fear but rather relaxation with the phobic object
Effectiveness of Systematic Desensitisation (SD)
SD appears to be an effective treatment for specific phobias
SD is not always effective; it can be quite ineffective for some phobias
Research was carried out by Rothbaum et al. (2000) who used SD to treat participants with a phobia of flying
Rothbaum compared participants with a phobia of flying who received SD against a control group who did not
Following SD, 93% of participants with a phobia of flying agreed to take a trial flight and had much lower levels of anxiety than the control group
Positive effects of SD were found 6 months after treatment
Patients who engage with SD show lower levels of anxiety when faced with their phobic scenario compared to patients who do not complete SD
This is evidence that therapy works and the effects are apparent immediately as well as some time after therapy is completed
It is unclear how long the positive effects of SD lasted for beyond the 6 months after treatment
SD does not universally work for all types of phobias, especially patients with phobias that have not evolved due to personal experiences (classical conditioning)
For example, heights are not effectively treated by SD
Phobias such as heights have an evolutionary survival benefit and therefore cannot be treated using the principles of conditioning (learning)
SD is ineffective, especially if the phobic object has some sort of evolutionary survival benefit
SD therapy
1. Valid consent is obtained from the client before SD can begin
2. The client is able to withdraw from the therapy at any point during the process
3. Introduction of relaxation techniques means clients rarely feel distress
SD therapy
More ethical than other therapies
Increases the individual's feeling of control
Therapist guides and helps the client without playing the central role
Puts the client at the heart of the therapy
Client dictates the pace of the therapy and is not coerced
Therapist is external to the therapy, reducing the risk of dependence or attribution of success to the therapist
SD therapy is
Very effective for specific phobias
Ethically sound
Offers a safe way for clients to face their phobia and improve their lives
Questions are raised regarding the universal application of SD therapy to all phobias and other mental illnesses
Critics argue that SD therapy does not address the root cause of the phobia, limiting its long-term success
Biological approach
Assumes that all psychological behaviour is the result of physical, rather than psychological, processes
Medical model
States that all psychological illnesses should be treated with physiological rather than psychological methods
