Alternative Evidence Rosenhan

Question	Answer
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
