In what way can we ever claim that a personality is ‘abnormal’?

Please proof read carefully! Also, I have used too many references. Could you please check which ones I could take out? Does it flow nicely and discuss the question appropriately? I will also attach notes by the professor that were meant to guide the 3000 word essay. Important to look at those! Additionally I will attach powerpoint presentations that were about the topic of abnormality. Does the essay go in hand with those?
