What did Loring and Powell do in 1988 | gave a transcript of a patient interview to psychologists, half told the p's were white and other half black --> black p's labelled as more violent & view with suspicion & danger |
Loring and Powell developed Rosenhans study.. | reliability, results support R as psychiatrists were influenced by ethnicity not individuals characteristics. Increases time validity and pop v- carried out on diff set of p's |
Describe Spitzer's experiment in 1975 | challenged R's findings, even though ppatients were misdiagnosed, psychiatrists rely upon verbal accounts &it is unlikely sane people try trick a psychiatrist to get into an institution |
Spitzer criticised Rosenhans study | as it suggests psychiatrists diagnose on individual characteristics and not context (relying upon verbal reports) Decreases external reliability due to the inconsistent results. |
Criteria for schizophrenia from the DSM IV | 2 or more symptoms including hallucinations, delusions, disorganised speech/behaviour, negative symptoms. Over a course of 6 months or longer |
Change in the DSM IV | suggests if study repeated the ppatients would not be diagnosed therefore criticising R. This again decreases external reliability |
Give the three pieces of alternative evidence you would use for Rosenhan | Spitzer (1975) Loring and Powell (1988) DSM IV criteria for schizophrenia |
