Question
A woman was treated by Glover (2011) for kleptomania. She had a 14-year history of daily compulsive shoplifting and was treated with covert sensitisation. At a 19-month follow-up she was free of stealing behaviour apart from one lapse, and there were corresponding improvements in her self-esteem and socialisation. (a) Explain what is meant by ‘covert sensitisation’. [2] (b) Outline how the aversive stimulus was used in the study by Glover (2011) to treat the woman’s kleptomania. [4] (c) Give two differences between covert sensitisation and imaginal desensitisation. [4] (d) Discuss the advantages and disadvantages of using covert sensitisation to treat impulse control disorders. You should include a conclusion in your answer.

1 A woman was treated by Glover (2011) for kleptomania. She had a 14- year history of daily compulsive shoplifting and was treated with covert sensitisation. At a 19-month follow-up she was free of stealing behaviour apart from one lapse, and there were corresponding improvements in her self-esteem and socialisation. 1(a) Explain what is meant by ‘covert sensitisation’. 2 Most likely answer (other appropriate responses to be credited): • Covert sensitisation is a form of behaviour therapy in which an undesirable behaviour is paired with an unpleasant image in order to eliminate that behaviour. • Desensitisation is opposite, so 0 marks. Marks: 1 mark for partial answer, 2 marks for elaboration/example. Example can be anything appropriate. Note: if above definition is given award 2 marks. 1(b) Outline how the aversive stimulus was used in the study by Glover 4 (2011) to treat the woman’s kleptomania. Most likely answers: quoting study • It was decided to use imagery of nausea and vomiting paired with the act of stealing. • Episodes of imagery were used involving increasing nausea as she approached an article in a supermarket which she intended to steal, leading to vomiting as she lifted the article, with other shoppers’ attention being attracted to her. • The vomiting and other unpleasant sensations ceased as soon as she replaced the article, turned away and left the shop Marks: 1–2 marks basic answer 3–4 marks detail/elaboration. 1(c) Give two differences between covert sensitisation and imaginal 4 desensitisation. Most likely answer (other appropriate responses to be credited): Difference: CS: client imagines engaging in the event (e.g. stealing) and experiencing negative consequences (such as vomiting). ID: uses progressive muscle relaxation with imagery of successfully avoiding event (e.g. stealing) Difference: CS: person creates an imagined unpleasant association between addictive behaviour and unpleasant stimulus. ID: relaxation based. Imaginal desensitisation significantly decreased the heightened state of arousal and anxiety typically associated with gambling urges Marks: 1 mark for description, 2 marks for direct difference (e.g. X is and Y is) x2 1(d) Discuss the advantages and disadvantages of using covert 5 sensitisation to treat impulse control disorders. You should include a conclusion in your answer. Marks: Question requires discussion; always plural of each argument, and always requires conclusion. 1 mark for each advantage/disadvantage (however basic/detailed) which is related to the question (max 4 marks). 1 mark for conclusion. 2 marks max for two strengths and two weaknesses unrelated to the question. Conclusion: any appropriate conclusion drawn from the discussion that has been presented. 1 mark if appropriate. A conclusion is a ‘decision reached by reasoning’ and so a summary of points already made scores 0 marks. Most likely answer (other appropriate responses to be credited): Advantages: • Techniques can be applied by anyone, in any place at any time. • Behavioural techniques focus on alleviating the symptoms of ICD rather than the cause • Behavioural techniques are more likely to be generalised because all people can learn and ‘unlearn’ following the same principles • No medication is taken; the patient cannot become addicted to medication. • The therapist will guide the patient through the treatment. Disadvantages: • Behavioural techniques take time and effort from the person (unlike swallowing a pill) • The techniques do not cure the ICD, merely make it easier to live with • Behavioural techniques ignore the role of biochemicals • A therapist is needed which is more costly than taking a drug. • Sensitisation involves imagining something unpleasant in association with the event, so is ‘negative’ rather than imaginal desensitisation which is more ‘positive’
