Q

Describe the biochemical reasoning of the Biological explanation

A
  • It states that there are low levels of dopamine and low levels of serotonin
  • low levels of dopamine: Shows a lack of interest in previously enjoyed tasks, low moods and motivation
  • Low levels of serotonin : low levels of mood an anxiety, changes in sleeping and eating patterns

Q

Describe the genetic reasoning of the Biological explanation

A
  • Current evidence has shown that first degree relatives such as parents/ siblings which share 50% of DNA are likely to transmit bipolar or unipolar. from one generation to the next.

Q

What was the procedure in Oruc

A
  • They carried out DNA testing to test for polymorphisms (variation) in the genes responsible for a particular serotonin receptor
  • These genes were selected because alterations in them have lead to disturbances in the biochemical pathways

21
Q

What were the results of the study Oruc

A
  • There was no significant relationship between people with bipolar and having polymorphisms compared to the control group
  • they found dopamine to be sexually dimorphic hence, women with bipolar showed that polymorphisms were more common in them that in the control group
22
Q

What was the conclusion in Oruc

A

The analysis suggested that polymorphisms of these geneses could be responsible for an increased risk in developing bipolar in females only.

23
Q

Evaluate Oruc et al.

A

+ Use of objective accurate data with the use of DNA testing, making it more precise and comparable
+ The results from the study can be used for application to everyday as this helps individuals who have relatives that are bipolar to go get screened or have an early diagnosis
-the study is limited due to a smaller sample size and due to the fact that all participants were from Croatia. Age could have also played a role on the results as most people in the control group were younger so could develop BP later

24
Q

Evaluate the biological explanation in terms of issues and debates

A
  • Supports the nature side of the debate suggesting that genes play a role
  • considered reductionist as it only gives the reasoning to genes and neurotransmitters but excludes other factors
  • Considered deterministic as it bases the explanation on someones genes which they cannot control and have no choice but to deal with their condition
25
Q

what did Beck define cognitive distortion as

A
  • He believed that this is when a person tends to see things in a negative way and were developed as a result of negative experiences in their childhood which later grew into negative schemas
26
Q

describe Beck’s cognitive triad

A

1- Negative views about oneself
2- Negative views about the world
3- Negative views about the future

27
Q

define attribution

A

the cognitive process wherein individuals explain the causes of particular events and behavior

28
Q

define learned helplessness

A

A behavior that occurs as a result of the person having to endure an unpleasant experience that they deem inescapable

29
Q

a negative event can be attributed to

A
  • internal(personal) VS external(environment)
  • stable (constant) VS unstable(occasional)
  • Global (affects many aspects) VS specific(affects one area)
30
Q

what was the aim of seligman et al.

A

to investigate how well attributional styles could predict depression

31
Q

describe the sample of Seligman

A
  • 39 patients with unipolar
  • 12 with bipolar
  • 10 from the control group
  • all patients were from the same clinic
  • included a mix of genders
  • average age of 36 years
32
Q

describe the attributional style questionnaire in seligman and how did the participants respond

A
  • a 12 item self-report of good and bad hypothetical situations
  • they had to attribute the cause for each scenario and rate them on a 7-point scale for internally, stability and globally
33
Q

State 3 results found in Seligman et al

A
  • The unipolar and Bipolar group had the most pessimistic negative attributional styles than the control group
  • The more severe the BDI score was, the worse the pessimism on ASQ
  • there was an improvement in attributional styles for patients with unipolar who are under CBT
34
Q

what did Seligman conclude

A

The way we make attributions can contribute to developing depression

35
Q

evaluate the BDI and ASQ

A

+ A standardized and consistent measure that is accurate hence, high validity
+ quantitative data which is objective and enables comparison
-socially desirable answers
-closed-ended questions limit individuals’ response
-Cultural differences as the BDI is designed towards the Western culture.

36
Q

Evaluate seligman et al.

A

+The use of quantitative measures such as questionnaires can allow for easy objective comparisons to be established
-Low number of participants hence lacks generalizability

37
Q

Evaluate the cognitive explanation of mood disorders

A
  • The holistic side of the debate is supported as it focuses on more than one aspect
  • supports the nurture side of the debate as individuals learn the behavior leading to depression
  • supports the nomothetic side of the debate as it produces quantitative data
  • to some extent, it is deterministic as they do not have any control over the events that cause helplessness\
  • Individual side of the debate blames it on theindividuals dysfunctional thinking style however sitauational side says helplessness arises due to their environment
38
Q

describe the biological treatment with Monoamine Oxidase inhibitors (MAOIs)

A
  • Monoamine Oxidase is an enzyme that breaks down neurotransmitters such as serotonin
  • MAOIs will inhibit these enzymes so that they can maintain high levels in the synapse
39
Q

List 5 side effects from MAOIs

A
  • Headaches
  • Diahorrea
  • Nausea
  • Insomnia
  • Suicidal thoughts
40
Q

Describe the biological treatment with Selective serotonin reuptake inhibitors (SSRIs) and how they work

A
  • This treatment only works on the neurotransmitter serotonin. It works by stopping its reabsorption into the pre-synaptic neuron, keeping it at high levels in the synapse
41
Q

What are the disadvantages of using ECT to treat depression

A
  • It is a short-term treatment so patients will resort back to other treatments
  • relapse rates are just as high as those stopping antidepressants and will have a reoccurrence of symptoms
42
Q

Describe the use of tricyclics as a biological treatment

A
  • They are the first-generation treatment and act as the last resort when other treatments fail
  • They increase the levels of serotonin and norepinephrine by stopping them from being reabsorbed
  • side effects include drowsiness and blurred vision
43
Q

Evaluate drug therapy as a treatment for depression

A

+Supports the nature side and targets neurotransmitters
+Readily available and less costly compared to other treatments
+Fournier et al. proved drugs are more effective in moderate to severe depression than those with mild
-side effects
-Deterministic as the patient cannot control the interaction of serotonin with the medication to bring about an improvement
-Reductionist as it only focuses on the improvement of symptoms

44
Q

describe becks cognitive restructuring talking therapy

A
  • First begins with the therapist explaining the theory of depression using the cognitive triad so the patient understands their thinking styles
  • patients are then trained to recognize and observe their thoughts and once they do recognize them they can link their thoughts to their behavior
  • They then discuss whether these thoughts are really an accurate reflection of reality.
  • The therapy finishes when the patient is able to employ cognitive restructuring for themselves and can see a reduction in their depressive symptoms
45
Q

Therapists often use ‘reattribution’ as a technique in therapy, what does it involve

A
  • This is where the therapist and patient discuss whether the cause of problems/failures they have faced are internal or external
  • By doing this, the patient can then refrain from thinking that they are responsible for bad situations happening to them.
46
Q

what did the study by Wise et al. find

A

those who received therapy were 3 times more likely to show a reduction in depressive symptoms `

47
Q

Define stoicism

A

This is a philosophy where one of the principles is that the individual is not directly affected by external things but by how they perceive those external things

48
Q

describe the ABC model of Ellis

A

A- activating event
B- beliefs
C- consequences

49
Q

Describe the Rational emotional Behaviour Therapy (REBT)

A
  • This therapy involves disputing with the patient whereby the therapist will forcefully question their irrational beliefs using a variety of methods
  • Patients must first see their C (consequences) and that they are partly a result of the A (activating event)
  • Then they must accept that holding onto negative and irrational B (beliefs) will result to a destructive tendency.
50
Q

What did Lyon and woods find out about REBT

A
  • They found that people who received REBT demonstrated significant improvements over baseline measures and the control groups
