LT6 Psychological Explanations of OCD Strengths Weaknesses psychodyn A01 Explanations/Research amic Psychologists within this group believe that the potential for developing OCD becomes fixed during the anal stage of development. Around the age of two One strength of Freud’s theory comes from further One weakness of Freud’s theory is that there is contradictory evidence provided by years old, when the id impulse is very destructive and gains pleasure from destroying things, and especially if parents are too strict with toilet training, the empirical support provided by Apter et al (1997).

This thought is very frightening and untenable to a person of any They assessed suicidal adolescents inpatients admitted on the recovery from OCD, which does little to support the Freudian approach. An age; in order to deal with the conflict between the id and the ego, the individual may develop four defense mechanisms: isolation, displacement, reaction for a definite suicide attempt in terms of their ego alternative is to use a short-term psychodynamic therapy. These tend to be more direct formation, and undoing, which express themselves in the form of the OCD paradigm. Individuals who suffer from OCD are therefore trapped in this stage of defence mechanisms. The adolescents scored higher and action-orientated and therefore reduce OCD patients’ tendency to ‘think too much’. development. on regression and other defence mechanisms than This suggests that there is refuting evidence for Freud’s psychoanalysis improving the non-suicidal patients. This suggests that there is quality of life for patients with OCD. Obsessive thoughts and compulsive actions. In Freud’s psychoanalytic theory, OCD arises when unacceptable wishes and impulses coming from the Id are wider academic credibility for the idea that ego only partially repressed, thus provoking anxiety. People with OCD use defence mechanisms to reduce the anxiety associated with these wishes and impulses. defences are associated with self-anger. A further weakness of Freud’s explanation of OCD is that the evidence on which his The four main defence mechanisms common to OCD are: observations of patients are based is unreliable. Freud often used case studies of his A further strength of Freud’s theory comes from patients to support his theory. Although this information is valid it is not testable or Isolation: People attempt to isolate themselves from, or disown, these undesirable wishes and impulses. Sometimes the defence mechanism predominates the more further empirical support from Adams et al. repeatable in any kind of scientific way and hence the results of such observations are id. When the id is dominant, the impulses intrude as obsessional thoughts. (1996). They produced evidence of reaction open to much interpretation and bias. This suggests that because Freud’s explanations are Undoing: When isolation is about to fail, the secondary defence of undoing produces compulsive acts.

Reaction formation: This involves adapting behaviours and character traits that are exactly the opposite of the unacceptable impulses. Compulsive kindness 80% of the ‘homophobics’ were aroused by the videos towards others may be a way of countering unacceptable aggressive impulses. Observes often see these patterns as highly exaggerated and sometimes quite of male homosexual sex compared with 33% of the A final weakness of Freud’s theory of OCD is that it is psychologically deterministic. often inappropriate. non-homophobic men. This suggests that there is For example, Freud’s theory claims that people have very little conscious involvement in Regression: In psychoanalytic theory, regression is an important mechanism in the formation of OCD symptoms. OCD patients can avoid the associated wider academic credibility for the idea that their own obsessive and compulsive acts, but instead their behaviour is governed by anxiety of genital impulses by partially regressing to an earlier phase of their development when where were concerned about controlling bodily functions. homophobia is a form of reaction formation. unconscious psychic conflicts. This suggests that individuals have little free will over By giving up their genital urges, they are no longer confronted by the conflicts and problems arising from these. Regression also unconsciously revives the their behaviour. childhood illusion that mere thoughts can cause external events. This magical thinking is what makes individuals with OCD believe that just thinking about an event in the external world can cause it to occur. This is what makes aggressive thoughts so frightening to OCD patients and compulsive actions so effective in bringing relief. behaviou A01 Explanations/Research ral Obsessional thoughts: Strengths Weaknesses One strength of the Behavioural approach is that it Mowrer (1960) claimed that stimuli acquire aversive properties through the process of classical conditioning. has practical applications. Rachman (1985) The fear associated with these stimuli is maintained over time by avoidance – avoiding a feared stimulus leads to developed his ideas into ‘exposure and response positive outcomes and thus reinforced (any action enabling the individual to avoid a negative event being prevention therapy’ (ERP), in which the patient is described as negatively reinforcing – operant conditioning). In OCD, thoughts and obsessions (e.g., about sexual exposed to the situations that trigger their obsessions, behaviour) are thought to become aversive through association with some traumatic event (e.g., parental but are prohibited in engaging in a compulsive punishment). AS a result, some people have been conditioned early in life to regard some thoughts as unclean, response. E.g., a woman obsessed with cleanliness immoral or even dangerous. As the thought re-occurs, it becomes a source of conditioned anxiety, like the object might be given a list of therapeutic rules she must of a phobia. The ritualistic behaviour seen in OCD is a way of avoiding these fear-associated obsessions, so is accept, like only cleaning her house once a week for reinforced. 30 minutes.

It has been found that 90% of adults Compulsive behaviour: Compulsive rituals develop as a means of neutralising (or avoiding) these fear-associated obsessions, reducing the who use ERP improve. This suggests that ERP can anxiety and re-establishing control over the obsessions. As a result, ritualistic behaviour is reinforced, and help to improve the quality of people’s lives with individuals may link whatever act they have performed with changing the fearful situation. In this way, accidental OCD. associations are formed and may become compulsive whenever the individual faces anxiety-provoking situations. Strengths cogniti A01 Explanations/Research ve The cognitive approach to OCD embodies a number of behaviourist principles so is more usually referred to as cognitive behavioural explanation One strength of the Cognitive One weakness of the behavioural approach is that there are ethical issues. Protection of PPs was clearly an ethical issue in ERP therapy, which the researchers acknowledge but felt it was justifiable because patients with OCD should show signs of recovery. However, do the ends justify the means? This suggests that therapies do not protect the Pp from psychological harm. A second weakness is that the behavioural approach is reductionist. The reason for this is because the behavioural account suggests that OCD occurs due to classical and operant conditioning and ignores biological factors such as genes and neurotransmitters. This suggests that the behavioural approach is oversimplistic when considering the cause of OCD. A third weakness is that the behavioural approach is environmentally deterministic. The behavioural explanation suggests that behaviour is controlled by the environment, such as parental punishment. This suggests that this explanation does not account for freewill. A final weakness of the behavioural explanation of OCD is the nature vs. nurture debate. Behavioural explanations account for nurture only as, according to these, behaviour is solely a product of learning as we are born as a blank slate. They ignore nature, which is a significant weakness as the biological explanation suggests neurotransmitters and the COMP gene are responsible for OCD. Weaknesses One weakness of the cognitive-behavioural approach is that there are ethical issues. Protection of PPs was clearly an ethical issue in ERP therapy, which of OCD. CB explanations of OCD stress that everyone sometimes has unwanted or intrusive thoughts (e.g., harming others or being contaminated explanation comes from further the researchers acknowledge but felt it was justifiable because patients with OCD should show signs of recovery. However, do the ends justify the means? by germs), but thoughts can fairly easily be ignored or dismissed. In some people, however, these thoughts are a cue for self blame and the empirical support provided by This suggests that therapies do not protect the Pp from psychological harm. expectation that terrible things will happen as a result. The thoughts continue because individuals cannot stop of ignore them easily. This is Piacentini et al. (2002). He used because they also have depression, which weakens their ability to distract themselves. cognitive-behavioural therapy with A second weakness is that the cognitive-behavioural approach is reductionist. The reason for this is because the behavioural account suggests that OCD children suffering from OCD and occurs due to classical and operant conditioning and ignores biological factors such as genes and neurotransmitters. This suggests that the behavioural found that there was a significant approach is oversimplistic when considering the cause of OCD. Neutralising anxiety through compulsive acts: In order to avoid the anticipated consequences of these thoughts, individuals must find a way of ‘neutralising’ them. Possible neutralising acts positive response to this form of include engaging in ritualistic compulsive behaviours as the person tries to relieve the anxiety produced by the unpleasant thoughts. However, treatment. This suggests that there is A third weakness is that the cognitive-behavioural approach is environmentally deterministic. The behavioural explanation suggests that behaviour is compulsive rituals such as hand washing after obsessive fear of contamination produce only temporary relief, anxiety building up again. Every time wider academic credibility for the idea controlled by the environment, such as parental punishment. This suggests that this explanation does not account for freewill. a neutralising thought or act is repeated, it becomes harder to resist because of the consequent reduction in anxiety; eventually in becomes, by of psychological treatments improving definition, a compulsion. Over time, people become more convinced that these intrusive thoughts are dangerous, and therefore their fear of them the quality of people’s lives. A final weakness of the cognitive-behavioural explanation of OCD is the nature vs. nurture debate. Behavioural explanations account for nurture only increases. In this way the thoughts turn into obsessions, and the need to reduce the anxiety associated with becomes even more acute. The pattern as, according to these, behaviour is solely a product of learning as we are born as a blank slate. They ignore nature, which is a significant weakness as the of behaviour characteristic of OCD is thus rather like an addiction – the more you do it, the more you have to do it. biological explanation suggests neurotransmitters and the COMP gene are responsible for OCD. In contrast the Biological approach refutes the psychological approach and instead suggests that OCD is caused by low levels of serotonin, the COMT gene and abnormalities in the OCF. This suggests that the Psychological explanations do not provide a full account of the causes of OCD. In conclusion the Diathesis Stress Model, which suggests that there is a genetic vulnerability to a disorder (Diathesis), but this is triggered when an individual has been exposed to a stressful life event (stress). Both of these factors are necessary for a disorder to develop. This is why not all the children with schizophrenia develop the disorder, and why the concordance rate for mental disorders for MZ twins is nothing like 100%.
