Hello again, I was hoping someone could help – I’m having trouble differentiating between AO1 and AO2 content for the issues of classification and diagnosis…
e.g. I take it this paragraph is AO1:
‘There are issues regarding the reliability of diagnosis of depression using tools such as the DSM due to a lack of clear, reliable, objective measures to determine whether a complaint is serious enough to meet the definition of a clinical characteristic, especially as moods fluctuate over time, so a diagnosis cannot be free from subjectivity.’
I can’t work out if this next part is AO1 or AO2, in your newest exam companion it lists this as AO2 but it seems like I’m jsut going further into the description rather than evaluating anything:
‘Keller et al has suggested that the reliability of the DSM suffers especially due to its strict criteria for diagnosis, e.g. for MDD to be diagnosed, a minimum of five out of 9 symptoms must be present, therefore disagreement between clinicians or change over time due to mood fluctuation in 1 item at the threshold could lead to a diagnosis of a less serious illness’.
I’ve got an essay written up which I think is okay, I’m jsut concerned about getting a short question that asks for just AO1 or something llike that. I hate this topic and I’m pretty sure it’s going to come up in some form!May 27, 2012 at 2:57 pm #2433
The reliability/validity question is a tricky one. If it comes up as an 8 + 16 marker then you do have to (1) describe an issue and then (2) evaluate that issue (twice as much evaluation as description).
I think your paragraph about Keller is really another piece of description – describing a second issue (that the criteria for for MDD are too strict). An AO2 paragraph would present evidence to support or challenge the issue you described OR would consider implications. In a sense you do go on to do this in the second part of the Keller paragraph (‘therefore …).
Examiners struggle to disentangle AO1 from AO2 so it would help you and them if you do a paragraph of AO1 followed by a paragraph of AO2. Each AO1 paragraph should begin ‘One issue is ..’ and then each AO2 paragraph should clearly begin with an AO2 link phrase e.g. ‘This is supported by ..’ or ‘This is not supported by ..’ or ‘However….’
Have a look at our A2 Exam Companion where we answered a question like this (see page 105 for one on depression).
