- Aim
- To see if the DSM can work out the difference between sane and insane people
- Rosenhan (1973) - On Being Sane in Insane Places
- Sample
- 8 pseudo-patients
- 1 graduate
- 3 psychologists
- 1 pediatrician
- 1 painter
- 2 housewives
- 5 male, 3 female
- 8 pseudo-patients
- Procedure 1
- 12 hospitals in 5 states
- Pseudo patients rang hospital asking for appointment
- Said they were hearing voices. They were unclear but they seemed to be saying 'empty', 'hollow' or 'thud'
- 7 were diagnosed with schizophrenia in remission
- Hospitalised - stayed in for 7-52 days - average 19 days
- Pseudos acted 'normally', responded to staff and other patients, made notes on observations, reported no more symptoms, asked staff when discharge would be likely
- 35/118 real patients were suspicious of pseudo patients
- Pseudos acted 'normally', responded to staff and other patients, made notes on observations, reported no more symptoms, asked staff when discharge would be likely
- Hospitalised - stayed in for 7-52 days - average 19 days
- 7 were diagnosed with schizophrenia in remission
- Said they were hearing voices. They were unclear but they seemed to be saying 'empty', 'hollow' or 'thud'
- Procedure 2
- Told would be visited by one or more pseudo patients in next 3 months
- asked to rate the likelihood of them being a pseudopatient on a 10-point scale
- 193 patients entered, none were pseudo
- 41 - high confidence to be pseudo by at least one staff member
- 23 - considered suspect by at least one psychiatrist
- 19 - thought to be pseudo by one psychiatrist and one staff member
- 193 patients entered, none were pseudo
- asked to rate the likelihood of them being a pseudopatient on a 10-point scale
- Told would be visited by one or more pseudo patients in next 3 months
- Evaluation
- Even though Rosenhan said DSM was invalid and unreliable, hospitals did the right thing to monitor them
- Small sample - hard to generalise
- Used a variety of hospitals which represents the US
- Good ecological validity - field experiment so natural setting
- Normal for a hospital to diagnose people who are hearing voices - isn't artificial
- Standardised procedure
- All 8 people acted in the same way, said same on phone, same symptoms, how they behaved after - can be replicated and tested for reliability
- Deception about illness - cause stress to staff
- Sample
