Psychopathology - Biological Approach for OCD AO3

Question 1

What are the strengths for the Biological approach for OCD?

Answer 1

• it was found by Soomro that antidepressants that increase seritonin levels can be used to decrease OCD symptoms
• Billett found conducted a meta analysis on 14 twin studies and found that MZ twins were 2 times more likely to get OCD if their twin has it

Question 2

What is a counter to Soomro’s findings?

Answer 2

the antidepressants isn’t100% effective which suggests there may be other factors that cause OCD than seritonin levels

Question 3

What is a counter to Billett’s twin study?

Answer 3

MZ twins share 100% of their DNA yet the probibility of having OCD if their twin has it isn’t 100% which suggests genes aren’t the only thing that causes OCD

Question 4

What is the weakness of the Biological Approach for OCD?

Answer 4

according to the diathesis stress model environmental factors activate genes that are related to disorders
this is supported by Cromer who found that in his study over half of his OCD participants experienced a traumatic event and the more severe their OCD the more traumatic events they experienced
this suggest Biological approach may be reductionist
