Q

Define statistical infrequency

A

A mathematical method for defining abnormality, based on the idea that if something occurs rarely then it is abnormal. (ie: being more depressed or less intelligent than the majority of the population)

Q

Give some examples of psychological disorders or behaviours that are statistically infrequent

A
  • Intellectual disability disorder (having an IQ below 70) - Schizophrenia (1 in 100 people have this) - OCD (1 in 100 people have this)

Q

How does standard deviation help us to see abnormalities?

A

Human attributes fall into a normal distribution within the population. This is displayed by the central average (mean). The rest of the population falls symmetrically above and below the mean. If a characteristic falls more than 2 standard deviations away from the mean then it is considered abnormal.

Q

Use statistical deviation to explain how we can tell when someone’s IQ is abnormal , indicating intellectual disability disorder

A
  • The average IQ is 100 - For IQ, 68% of people fall within one standard deviation from the mean - The standard deviation for IQ is 15, so 68% of the population score between 85 and 115 on an IQ test - For IQ, 95% of people fall within two standard deviations from the mean - The standard deviation for IQ is 15, so 95% of the population score between 70 and 130 on an IQ test - Anybody scoring lower of higher than this range would be considered abnormal

Q

What were Rosenhan and Seligman’s seven criteria for failing to function adequately? Displaying a great number of these is indication of a psychological disorder

A
  • Suffering - Maladaptiveness (engages in behaviours that make it difficult for them to lead their normal life) - Irrational - Observer discomfort (others find the person’s behaviour uncomfortable to watch) - Vividness (unconventionality) - Violation of moral codes - Unpredictability

Q

Why would not everyone benefit from being labelled as abnormal?

A

If someone is living a happy and fulfilled life, there would be no benefit to them being labelled as abnormal, no matter how unusual they are. Being labelled may have a negative effect on how others view them and how they view themselves.

Q

What is a strength of defining abnormality via deviation from social norms?

A

It takes into account the desirability of the behaviour. This contrasts with statistical deviation. According to statistical deviation, someone with abnormally high IQ may be considered negative. According to deviation from social norms, however, having an abnormally high IQ would not be a problem.

Q

Why are some people unable to look away from a phobic stimulus?

A

If something is a threat to us, it is a good thing to keep our attention on it as this gives us the best chance of survival. Because the phobic stimulus is perceived as a threat, the sufferer will be unable to focus on anything else.

Q

What is classical conditioning?

A

It is learning through association. It occurs when two stimuli are repeatedly paired together - an unconditioned stimulus and a new neutral stimulus. The neutral stimulus eventually produces the same response that was first produced by the unconditioned stimulus alone.

Outline the procedure of the ‘Little Albert’ experiment

A

A nine month old baby (Albert) showed no unusual anxiety at the start of the study and wanted to play with a white rat when it was shown to him. The experimenters gave Albert a phobia by making a loud, frightening noise using an iron bar whenever the rat was presented.

Q

Explain the ‘Little Albert’ experiment in terms of classical conditioning

A

The was an unconditioned stimulus that created an unconditioned fear response to it. The rat (neutral stimulus) and the unconditioned stimulus were encountered close together so that, in time, they produce the fear response together. Albert became afraid when he saw the rat as the rat became the conditioned stimulus. His fear was the conditioned response.

Q

How does operant conditioning make a phobia long lasting?

A

When someone avoids a phobic stimulus they successfully escape the fear and anxiety that they would have suffered if they remained. This reduction in fear negatively reinforces the avoidance behaviour so the phobia is maintained.

Q

A control group who had not experienced a traumatic event only had a 21% rate of dental anxiety.

  • Some avoidance behaviour is motivated more by positive feelings of safety rather than anxiety reduction Eg: - For an agoraphobic person, not leaving the house is not so much to avoid the phobic stimulus but to stick with the safety factor - This explains why some agoraphobic patients can leave their house with a trusted person or relative without feeling much anxiety, but not alone

Q

How are the cognitive aspects of phobias not covered properly?

A
  • Behavioural explanations (eg: two process model) are geared toward explaining behaviour, which is most often avoiding the phobic stimulus - Phobias are not just avoidance responses so the cognitive component of them must be explained as well - The two process model explains avoidance behaviour but not other things such as irrational beliefs about the phobic stimulus

Q

Give an examples of how phobias don’t follow a trauma

A
  • Common phobias such as snake phobias occur in populations where very few people have any experience of snakes - Some traumatic events don’t lead to phobias

101
Q

Define systematic desensitisation

A

A behavioural therapy designed to gradually reduce phobic anxiety through the principle of classical conditioning. If a person can learn to relax in the presence of the phobic stimulus then they will be cured.

102
Q

What is the learning of a different response called?

A

counterconditioning

103
Q

What are the 3 processes involved in systematic desensitisation?

A
  • Anxiety hierarchy - Relaxation - Exposure
104
Q

What is the anxiety hierarchy?

A
  • Put together by the client with a phobia and their therapist - A list of situations related to the phobic stimulus that provoke anxiety arranged in order from least to most frightening
105
Q

Give an example of an anxiety hierarchy for someone afraid of the sea

A
  • A picture of the sea - A video of the sea - Standing near the sea - On a boat on the sea - Swimming in the sea - Staying underwater for a period of time in the sea
106
Q

What is involved in the relaxation stage of systematic desensitisation?

A

The therapist teaches the client to relax as deeply as possible. This might involve… - Breathing exercises - Mental imagery techniques - Meditation - Drugs such as Valium

107
Q

What is the official term for the idea that a person cannot be in two opposing states at once (ie: scared and relaxed)?

A

Reciprocal inhibition

108
Q

How is reciprocal inhibition relevant to systematic desensitisation?

A

By making their clients as relaxed as possible, therapists eliminate the chance of them experiencing fear at the same time. This can be utilised for when the client comes into contact with the phobic stimulus.

109
Q

What is involved in the exposure stage of systematic desensitisation?

A
  • The client is exposed to the phobic stimulus while in a relaxed state - This takes place across several sessions, starting at the bottom of the anxiety hierarchy - When the client stays relaxed in the presence of lower levels of the phobic stimulus, they can move up the hierarchy - The treatment is complete when the client can stay relaxed at the top of the anxiety hierarchy
110
Q

Name the strengths of systematic desensitisation

A
  • Evidence of effectiveness - People with learning disabilities
111
Q

Name the weaknesses of systematic desensitisation

A
  • It ignores certain factors that could contribute to phobias - It is more appropriate for some phobias than others
112
Q

What evidence is there of the effectiveness of systematic desensitisation?

A
  • Lisa Gilroy et al (2003) followed up 42 people who had systematic desensitisation for spider phobia in three 45 minute sessions - At both 3 and 33 months, the systematic desensitisation group were less fearful than a control group treated by relaxation without exposure
113
Q

How do people with learning disabilities support systematic desensitisation?

A
  • Some people requiring treatment for phobias also have a learning disability - Cognitive therapies that require complex rational thought are often not appropriate to treat these people. Flooding may also be too distressing and traumatic for them - This means that systematic desensitisation is the most appropriate treatment for people with learning disabilities who have phobias
114
Q

How does systematic desensitisation not address certain factors that can cause phobias?

A
  • Cognitive factors such as irrational beliefs and distortions of the phobic object are not addressed
115
Q

Why is it a problem that systematic desensitisation doesn’t address cognitive factors of phobias?

A
  • The effects may not be as long lasting as it doesn’t delve as deep as it could
116
Q

What type of phobia is systematic desensitisation better for?

A
  • Simpler phobias (such as arachnophobia) rather than complex ones like social phobias
117
Q

Why is systematic desensitisation better for simpler phobias?

A

It would be more practically difficult to gradually expose people to different levels of social interaction, for example

118
Q

Define flooding

A

A behavioural therapy in which a person with a phobia is exposed to an extreme form of a phobic stimulus in order to reduce the anxiety it triggers

119
Q

How long does a flooding session usually last for?

A
  • Until the patient is relaxed - Often 2 - 3 hours
120
Q

How could flooding be used on someone with arachnophobia?

A

A large spider might crawl over them for an extended period

121
Q

Explain how flooding works

A
  • A person’s fear response has a limited duration - As anxiety levels naturally decrease, a new stimulus response link can be formed between the feared stimulus and relaxation (this is called extinction) - Some patients become relaxed due to exhaustion
122
Q

What ethical safeguards are required for flooding?

A

It is a very unpleasant experience, so it is important patients give fully informed consent and are prepared.

123
Q

What are the strengths of flooding?

A
  • Cost-effective
124
Q

What are the weaknesses of flooding?

A
  • Is less suited to complex phobias - It is highly traumatic
125
Q

Why is flooding cost-effective?

A
  • It can work in as little as one session (as opposed to around 10 sessions for systematic desensitisation) - Ougrin (2011) compared flooding to cognitive therapies and found that it is just as effective
126
Q

How is flooding not as suitable for more complex phobias?

A
  • Social phobias have cognitive aspects - Eg: a sufferer of a social phobia doesn’t only experience an anxiety response, but thinks unpleasant thoughts about the social situation - Cognitive therapies would be more useful in this instance
127
Q

What does the traumatic nature of flooding lead to a high rate of?

A

Attrition (people dropping out of the therapy)

128
Q

What are the two cognitive approaches to explaining depression?

A
  • Beck’s negative triad - Ellis’ ABC model
129
Q

What 3 things did Beck suggest make a person more vulnerable to depression?

A
  • Faulty information processing - Negative self schemas - The negative triad
130
Q

What is involved in faulty information processing?

A
  • Depressed people often attend to the negative aspects of a situation rather than the positive - Depressed people may blow problems out of proportion - Depressed people may see things in ‘black and white’ terms
131
Q

What is a schema?

A
  • A package of ideas and information developed through experience - They act as a mental framework for the interpretation of sensory information
132
Q

What is a self schema?

A

The package of information we have about ourselves

133
Q

What is the negative triad?

A
  • The three types of negative thinking that occur automatically, regardless of the reality of the situation
134
Q

What are the components of the negative triad?

A
  • Negative view of the world - Negative view of the future - Negative view of the self
135
Q

What does negative view of the world involve?

A

Thinking about: - The state of the world - What other people are like - How others treat you

136
Q

What does negative view of the future involve?

A
  • Hopeless, despairing beliefs about what will or won’t happen
137
Q

What does negative view of the self involve?

A
  • Beliefs about the kind of person you are - Views of what we can/can’t do
138
Q

What are the strengths of Beck’s theory?

A
  • Supporting research - Practical applications
139
Q

What are the weaknesses of Beck’s theory?

A
  • It fails to explain where negative thinking comes from
140
Q

What supporting research is there for Beck’s theory?

A
  • Clark and Beck concluded that cognitive vulnerabilities (such as faulty information processing, negative self-schemas, the negative triad) are more common in depressed people and preceded the depression - Cohen et al tracked the development of 473 adolescents, regularly measuring their cognitive vulnerability. They found that showing cognitive vulnerability predicted later depression - Grazioli and Terry measured negative thinking patterns in 65 pregnant women. They found that women with a high cognitive vulnerability were more likely to suffer with post natal depression
141
Q

What are the practical applications of Beck’s theory?

A
  • The cognitive ideas have been used to develop effective treatments for depression, including CBT - Therapy looks to challenge negative views (ie: the negative triad)
142
Q

Why is it a problem that Beck’s theory fails to explain where negative thinking comes from?

A
  • It ignores important factors such as genetics, brain chemistry, upbringing, social class, etc - It doesn’t help prevent depression in any way; just identifies it
143
Q

What did Ellis say good mental health is the result of?

A

Rational thinking that allows people to be happy and free from pain

144
Q

What did Ellis define irrational thoughts as?

A

Any thoughts that interfere with us being happy or free from pain

145
Q

What does the ABC model stand for?

A
  • Activating event - Beliefs - Consequences
146
Q

What is the activating event?

A
  • An external event that triggers irrational thoughts - Eg: failing a test or ending a relationship
147
Q

Give 3 examples of irrational beliefs Ellis identified

A
  • Musturbation: belief that we must always achieve perfection - I-can’t-stand-it-itis: belief that it is a major disaster if something doesn’t go smoothly - Utopianism: belief that life is always meant to be fair
148
Q

What are the consequences in Ellis’ theory?

A

When an activating event triggers irrational beliefs there are emotional and behavioural consequences eg: if someone believes they must always succeed, and then fails at something - it can cause depression

149
Q

What is a healthy thought process (according to Ellis)?

A

Activating event –> Rational belief –> Healthy negative emotion

150
Q

What is an unhealthy thought process (according to Ellis)?

A

Activating event –> Irrational belief –> Unhealthy negative emotion

151
Q

What is a strength of Ellis’ theory?

A
  • Real world application
152
Q

What are the weaknesses of Ellis’ theory?

A
  • Reactive and endogenous depression - Ethical issues
153
Q

What are the real world applications of Ellis’ theory?

A
  • Ellis’ method for treating depression is called Rational Emotive Behaviour Therapy. - There is some evidence that it is able to change the negative beliefs of depressed people
154
Q

Define reactive and endogenous depression

A

Reactive: depression as a result of an external factor Endogenous: depression as a result of no external factor

155
Q

Why is it a problem that Ellis’ ABC model only caters to reactive depression?

A
  • It should look at all cases of depression: even the ones that don’t seem to be caused by a specific event
156
Q

What are the ethical issues with Ellis’ ABC model?

A

It places the responsibility of depression solely on the depressed person. This effectively blames them, which is unfair

157
Q

What are the two cognitive methods of treating depression?

A
  • Beck’s cognitive therapy - Ellis’ rational emotive behaviour therapy
158
Q

What is cognitive behaviour therapy?

A

A method for treating mental disorder based on both cognitive and behavioural techniques

159
Q

What is involved in the cognitive element of CBT?

A

It begins with an assessment in which the client and the cognitive behaviour therapist work together to clarify the client’s problems. They jointly identify goals for the therapy and put together a plan to achieve them. One of the central tasks is to identify where there might be negative or irrational thoughts that will benefit from challenge

160
Q

What is involved in the behaviour element of cognitive therapy?

A

CBT involves working to change negative and irrational thoughts in order to put more effective behaviours in place

161
Q

What does Beck’s cognitive therapy aim to do?

A

Replace negative and irrational thoughts with more positive and rational ones

162
Q

How does Beck’s cognitive therapy work?

A
  • Patients participate in thought catching: identifying automatic irrational thoughts about the self, world and future - The negative thoughts are challenged - The patient might be set homework tasks to test the validity of their negative beliefs
163
Q

Give an example of a homework task that could be set for someone undergoing Beck’s cognitive therapy

A
  • They have to record when they enjoyed an event or when people were nice to them
164
Q

What do the homework tasks provide?

A
  • Evidence against the patient’s negative thoughts, making the patient into a scientist - It encourages the patient to participate in everyday life, providing behavioural activation
165
Q

What does REBT do with the ABC model?

A

Expands it to the ABCDE model

166
Q

What do D and E stand for (as add ons to the ABC model)?

A

D: disputing E: effect

167
Q

What is the central technique for REBT?

A

To identify and dispute irrational thoughts

168
Q

How would an REBT therapist react if a patient talks about how unfair things seem?

A
  • They would identify this as examples of utopianism and challenge it as an irrational belief - This would involve vigorous argument
169
Q

What does the REBT therapist aim to achieve?

A

To break the link between negative life events and depression

170
Q

Name the 3 different methods of disputing identified by Ellis

A
  • Empirical argument - Logical argument - Pragmatic argument
171
Q

What does empirical argument involve?

A

Disputing whether there is actual evidence to support the negative belief

172
Q

What does logical argument involve?

A

Disputing whether the negative thought logically follows the facts

173
Q

What does pragmatic argument involve?

A

Emphasising the lack of usefulness of self-defeating beliefs

174
Q

What are the strengths of CBT?

A
  • Evidence to support effectiveness - Cost-effective
175
Q

What are the weaknesses of CBT?

A
  • Not suitable for all clients - Success may be due to patient therapist relationship - Cognitions are overemphasised - Some patients may want to explore their past - Relapse rates
176
Q

What evidence supports CBT?

A
  • March et al compared CBT to antidepressant drugs and to a combination of both treatments when treating 337 depressed adolescents. - After 36 weeks, 81% of the antidepressants group and 86% of the antidepressant plus CBT group were significantly improved. - CBT was just as effective when used on its own and more so when used alongside antidepressants
177
Q

Why is CBT cost effective?

A

It is a fairly brief therapy that usually requires 6 to 12 sessions

178
Q

Who has it been suggested that CBT is not effective for?

A
  • Severe cases of depression - People with learning disabilities
179
Q

Why might CBT not be effective for people with severe depression?

A
  • They might not be able to motivate themselves to engage with the cognitive work of CBT - They may not be able to pay attention to what is happening in a session
180
Q

Why might CBT not be suitable for people with learning disabilities?

A

It involves complex rational thinking

181
Q

Why might successful CBT be down to patient-therapist relationship rather than the actual effectiveness of the treatment?

A
  • Luborsky’s study reviewed multiple psychotherapies (including CBT) and found very small differences between their methods - This means that it might be down to the therapist rather than the individual method
182
Q

How are cognitions overemphasised in CBT?

A

If someone is living in maladaptive circumstances, simply changing thinking patterns won’t be enough to rid them of depression. This lack of success may lead the patient to believe that they are not strong enough to fight their mental illness and could make it worse.

183
Q

Explain how CBT doesn’t help patients explore their past

A
  • It only look at combatting current negative thoughts; not past ones
184
Q

Why is it a weakness that CBT doesn’t help patients explore their past?

A

Patients may not be able to explore things that could help them recover

185
Q

What recent study suggests that CBT’s effects are not as long lasting as hoped?

A

Shehzad Ali et al

186
Q

What did Shehzad Ali et al find?

A
  • Assessed depression in 439 clients every month for 12 months following a course of CBT - 42% of clients relapsed into depression within 6 months of ending treatment - 53% relapsed within a year
187
Q

Define biological approach

A

A perspective that emphasises the importance of physical processes in the body such as genetic inheritance and neural function

188
Q

What is involved in in individual vulnerability to OCD?

A

Genes

189
Q

Who’s study suggests that OCD runs in families?

A

Lewis (1936)

190
Q

What did Lewis’ study find?

A

Of Lewis’ OCD patients, - 37% had parents with OCD - 21% had siblings with OCD

191
Q

What does the diathesis-stress model state?

A
  • Certain genes leave some people more likely to develop a mental disorder but it is not certain - Some environmental stress is necessary to trigger the condition
192
Q

What are the three genetic explanations for OCD?

A
  • Candidate genes - OCD is polygenic - Different types of OCD
193
Q

What are candidate genes?

A

Genes that researchers have identified that create vulnerability for OCD

194
Q

What are candidate genes often involved in?

A

Regulating the development of the serotonin system

195
Q

Give an example of a candidate gene

A
  • 5HT1-D beta is implicated in the transport of serotonin across synapses
196
Q

OCD is polygenic. What does polygenic mean?

A

It means that OCD is not caused by one single gene but by a combination of genetic variations that gather together significantly to increase vulnerability

197
Q

Who studied the genes that may cause OCD?

A

Taylor (2013)

198
Q

What were Taylor’s findings?

A

Taylor analysed findings of previous studies and found evidence that up to 230 different genes may be involved in OCD

199
Q

What types of genes have been studied in relation to OCD?

A
  • Those associated with the action of dopamine - Those associated with the action of serotonin - Both of these are neurotransmitters involved in regulating mood
200
Q

One group of genes may cause OCD in one person but a different group of genes may cause the disorder in another person. What is the term used to describe this?

A

Aetiologically heterogeneous

201
Q

Give an example of a type of OCD that may be a result of particular genetic variations

A
  • Hoarding disorder - Religious obsession
202
Q

What is a strength of the genetic explanations for OCD?

A

There is a lot of strong evidence

203
Q

Give some examples of the strong evidence for genetic explanations of OCD

A
  • Twin studies. Nestadt reviewed twin studies and found that 68% of identical twins (MZ) shared OCD as opposed to 31% of non-identical twins (DZ) - Family studies. Marini and Stebnicki found that a person with a family member diagnosed with OCD is around four times as likely to develop it as someone without
204
Q

Name the weaknesses of the genetic explanations of OCD.

A
  • Environmental risk factors - Identifying specific genes that cause OCD - Animal studies
205
Q

Why are environmental risk factors a weakness of the genetic explanations of OCD?

A
  • They suggest that OCD isn’t entirely biologically influenced - Cromer’s study found that over half the OCD clients in their sample had experienced a traumatic event in their past - OCD is often more severe in those with traumas - Genetic vulnerability only provides a partial explanation for OCD
206
Q

Why are psychologists unable to identify the specific genes that cause OCD?

A

There are probably several genes involved and each genetic variation only increases the risk of OCD by a fraction

207
Q

Why is the fact that scientists can’t identify the specific genes that cause OCD a weakness of the theory?

A

It means the genetic explanation doesn’t have as much predictive volume

208
Q

Why are animal studies a weakness of the genetic explanations of OCD?

A

Although animal studies show that particular genes are associated with repetitive behaviours in other species (eg: Ahmari 2016 studied mice), the human mind is much more complex than mice. It therefore may not be possible to generalise from animal repetitive behaviour to human OCD.

209
Q

What are neural explanations?

A

The genes associated with OCD are likely to affect the levels of key neurotransmitters as well as structures of the brain

210
Q

Name the two neural explanations for OCD

A
  • The role of serotonin - Decision making systems
211
Q

What is serotonin?

A

A neurotransmitter believed to help regulate mood

212
Q

What are neurotransmitters responsible for?

A

Relaying information from one neuron to another

213
Q

What happens if someone has low levels of serotonin?

A
  • Normal transmission of mood-relevant information does not take place - They may experience low moods - Other mental processes may be affected
214
Q

Explain how there may be less serotonin in OCD sufferers.

A
  • Scientists believe that people with OCD have a genetic mutation that produces an abnormally high amount of serotonin uptake receptors on the sending neuron - This means that too much serotonin gets reabsorbed back into the sending cell so not enough is left in the synapse for transmission
215
Q

Give an example of a type of OCD associated with impaired decision making

A

Hoarding disorder

216
Q

Which parts of the brain will be functioning abnormally if decision making is affected?

A
  • The lateral (side bits) of the frontal lobes - Are responsible for logical thinking and decision making - The parahippocampal gyrus - Associated with processing unpleasant emotions
217
Q

Name the strength of the neural explanations of OCD

A
  • Research support
218
Q

Name the weaknesses of the neural explanations of OCD

A
  • It isn’t clear which neural mechanisms are involved - Co-morbidity
219
Q

What research support is there for the neural explanations of OCD?

A
  • Antidepressants that work purely on serotonin are effective in reducing OCD symptoms and this suggests that serotonin may be involved in OCD - OCD symptoms form part of conditions that are known to be biological in origin, such as Parkinson’s disease that causes muscle tremors and paralysis (Nestadt et al, 2010)
220
Q

What is co-morbidity?

A

Having two disorders together

221
Q

Why does co-morbidity weaken the neural explanations of OCD?

A
  • Many people with OCD also experience clinical depression - The depression probably involves (though is not necessarily caused by) disruption to the action of serotonin - This could mean that serotonin activity is disrupted in many people with OCD because they are depressed as well - This means serotonin may not even be relevant to OCD symptoms
222
Q

Why isn’t it clear which neural mechanisms cause OCD?

A
  • Cavedini et al’s study found that decision making neural systems are the ones that function abnormally in OCD - Other research has identified other brain systems that may be involved - No one single system has always been found responsible
223
Q

Why is the lack of clarity surrounding the mechanisms causing OCD a weakness of the neural explanations?

A

It means more research need to be done

224
Q

What is drug therapy?

A

Treatment involving drugs (ie: chemicals that have a particular effect on the functioning of the brain or some other bodily system)

225
Q

What does drug therapy for mental disorders aim to do?

A

To increase/decrease levels of neurotransmitters in the brain or increase/decrease their activity

226
Q

What do drugs used to treat OCD usually do?

A

Work in various ways to increase the level of serotonin in the brain.

227
Q

Name the 3 types of biological approach to treating OCD

A
  • SSRIs - Combining SSRIs with other treatments - Alternatives to SSRI drugs such as tricyclics and SNRIs
228
Q

What is a neurotransmitter?

A

A chemical substance released at the end of a nerve fibre by the arrival of a nerve impulse

229
Q

What does SSRI stand for?

A

Selective serotonin reuptake inhibitor

230
Q

What happens to serotonin in the brain?

A
  • It is released by the presynaptic neurons and travels across a synapse - The neurotransmitter chemically conveys the signal from the presynaptic neuron to the postsynaptic neuron - It is reabsorbed by the presynaptic neuron where it is broken down and reused
231
Q

How do SSRIs increase levels of serotonin in the synapse?

A

They prevent the reabsorption and breakdown of serotonin, continuing to stimulate the post synaptic neuron.

232
Q

Give an example of an SSRI

A

Fluoxetine (eg: brand name Prozac)

233
Q

What is a typical daily dose of fluoxetine?

A

20mg, although this can be increased if it is not benefitting the person

234
Q

In what form is fluoxetine available?

A

Capsules or liquid

235
Q

How long does it take for SSRIs to have much impact on symptoms?

A

Three to four months of daily use

236
Q

What is often used alongside SSRIs to treat OCD?

A
  • Drugs - Cognitive behaviour therapy
237
Q

What do drugs used to treat OCD alongside SSRIs do?

A

Reduce a person’s emotional symptoms, such as feeling anxious or depressed. This means that people can engage more effectively with the CBT.

238
Q

Some people respond best to (a) alone whilst others benefit more when additionally using (b) like (c).

A

a) CBT b) drugs c) fluoxetine

239
Q

Give two examples of alternative drugs that can be used if SSRIs don’t work

A
  • Tricyclics - SNRIs
240
Q

What are tricyclics?

A

An older type of antidepressant

241
Q

Give an example of a type of tricyclic

A

Clomipramine

242
Q

What does clomipramine do?

A

Acts on various systems including the serotonin system where it has the same effect as SSRIs

243
Q

Why is clomipramine not regularly used?

A

It has more severe side effects

244
Q

What does SNRI stand for?

A

Serotonin-noradrenaline reuptake inhibitors

245
Q

What do SNRIs do?

A

Increase levels of serotonin as well as another different neurotransmitter - noradrenaline

246
Q

Name the strengths of the biological approach to treating OCD

A
  • Clear evidence for effectiveness - Cost effective and non-disruptive
247
Q

Name the weaknesses of the biological approach to treating OCD

A
  • Serious side effects - Biased evidence
248
Q

What evidence is there for the effectiveness of drug treatments for OCD?

A
  • Soomro et al reviewed 17 studies that compared SSRIs to placebos in the treatment of OCD. All 17 studies showed significantly better outcomes for the SSRIs than for the placebo conditions. - Typically, symptoms reduce for for around 70% of people taking SSRIs. The remaining 30% can be helped by either alternative drugs or combinations of drugs and psychological therapies.
249
Q

Why are drug treatments cost effective?

A
  • They are cheap compared to psychological treatments - Many thousands of tablets or liquid doses can be manufactured in the time it takes to conduct one session of a psychological therapy
250
Q

How are drug treatments non-disruptive?

A

If you wish to take drugs you can simply take drugs until your symptoms decline. This is different form psychological therapy, which involves time spent attending therapy sessions.

251
Q

What are some of the side effects of drug treatments for OCD?

A

SSRIs: - Indigestion - Blurred vision - Loss of sex drive Clomipramine: - Erection problems - Weight gain - Aggression - Heart related problems

252
Q

Why might evidence for the effectiveness of drugs be biased?

A

Some psychologists believe that researchers are sponsored by drug companies and may selectively publish positive outcomes for the drugs their sponsors are selling.
