Discuss issues associated with the classification and/or diagnosis of schizophrenia.
Pharmaceutical industry make diagnosis more biased and psychiatrists are more likely to over diagnose patients.
DSM is still necessary as there no objective way to measure mental illnesses, it should be used as a reference
The fact that most psychiatrists state that they prescribe medicine by trial and error is worrying and unethical
Alternate methods for diagnosis should be used if possible, not just DSM
A lot of mental illnesses added to the DSM recently seem made up and are normal behaviours e.g. rebellion disorder.
This could be due to psychiatrist's association with the pharmaceutical industry. More diagnosis of mental disorders= more medicine prescribed.
The effect of labelling someone could be detrimental- could be an issue with self fulfilling prophecy
Inter rater reliability- similar diagnosis between two different people
Test retest reliability- same person testing again and again to get the same results
Measuring tool determines reliability
How can it be valid when it isn't reliable? Vice versa
DSM and ICD diagnose differently, ICD has a smaller timeframe to diagnose patients (symptoms need to be present for a month) compared to DSM (6 months)
This may imply that it is easier to diagnose someone using ICD
A lot of symptom overlap that does not have tests to determine the exact diagnosis
DSM is produced by the American Psychiatric Association but used almost worldwide... cultural bias?
ICD is more concise and DSM is more descriptive (exhaustive)
3 types of validity
Cultural bias (affecting reliability)
Gender bias (affecting reliability)
Symptom overlap (affecting validity)
Co-morbidity (affecting validity)
