Aim
To test the reliability of diagnosis of psychological abnormality
Do you characteristicsthat lead to a diagnosis come from their environment or from patients themselves
Method
Field experiment
Iv&dv
Iv- pseudo patient or real patient
Dv- behaviour of ward staff ,psychiatrists, nurses and the real patience
Participants
The staff and patience in 12 different hospitals across five different states in America
Procedure
Pseudo patient asked for an appointment and told admission officer that they had been hearing voices and voice was unclear but said words like, empty, Hollow, and thud. Voice was same-sex as themselves. Pretended to be worried about meaning of life.
All pseudo patients except one where admitted to hospital. Onwards they continue to behave as normal and take notes on experience.
In four of hospitals pseudo patient approach to staff member and asked’pardon me, could you tell me when I will be presented at the staff meeting’, or ‘when am I likely to be discharged’
As a control a record was kept of a young lady approaching staff members on the university campus asking six questions. All the staff members stopped and answered all questions and the respondents maintained eye contact with the lady
Only 4% of psychiatrists and even fewer nurses stopped and answer the question posed by pseudo patient and most continued without pausing
Controls
All pseudo patients reported same symptoms
All took notes on same way
Findings
All pseudo patients released with the label schizophrenia in remission
Length of stay range between 7 to 52 days average being 19
Some real patience seemed aware of sanity of pseudo patients and some commented that they were journalists
Pseudo patients flashed medication down loo and reported some real patients doing this too
Normal behaviour reported as abnormal for example writing notes was described as ‘the patient engaged in writing behaviour’ and arriving early for lunch was described as ‘oral acquisitive syndrome’
Follow-up study
Staff informed of results and told that at some time during the next three months one or more pseudo patients would attempts to be admitted to the hospital
Each member of staff was asked to rate the patience and the likelihood that they were pseudo patients on a 10 point scale
193 patience what judged. None with pseudo patients. 41 confidently judged to be pseudo patient
Conclusions
Doctors bias to making type two errors. As it is potentially dangerous to release sick person without treatment
Diagnosis of psychological abnormality are not reliable
Approach
Individual differences
