b) Suggest why health professional made type 2 errors in the original diagnosis of the pseudopatients. (2)
b) Outline one reason why it is difficult to define abnormality and normality. (2)
b) Outline one possible explanation for the behaviour of staff in this study. (2)
Any two of the following:
Staff treated the patients with little respect:
• Punishing patients for small incidents
• beating them and swearing at them
• patients cannot initiate contact with staff
• personal privacy is minimal (e.g. staff can enter private rooms with no permission, no doors on toilets)
• anyone can read patients’ files (e.g. volunteers on wards)
• physical examinations can be conducted in semi-public rooms
• general activity conducted around patients as if they are invisible
Any one of the following:
b) Give one example how the label ‘schizophrenia’ affected the way pseudopatient’s behaviour was interpreted by staff. (2)
• Once a person is labelled ‘abnormal’, this means that all subsequent data about them are interpreted in that light. Labels are also self-fulfilling for psychiatrist and for the patients themselves.
• The failure to detect the pseudopatients’ sanity may be because the doctors have a strong bias towards the ‘type 2 error’ – they are more inclined to call a healthy person sick (a false positive, type 2 error) than a sick person healthy (a false negative, type 1 error). It is clearly more dangerous to misdiagnose illness than health, and err on the side of caution.
