Background and Context of the Study

Background and Context of the Study

  • In the early 1970s, the validity of psychiatric diagnoses was a contentious issue; David Rosenhan sought to contribute to this debate.
  • Rosenhan's study intended to test the hypothesis that psychiatrists cannot reliably tell the difference between people who are 'sane' and those who are 'insane'.
  • His study was a response to the medical model of mental illness, which posited that mental illnesses are akin to physical illnesses.
  • According to this model, mental illnesses have specific symptoms and can be diagnosed and treated systematically.
  • However, Rosenhan argued that diagnosis of mental illnesses was often flawed and unreliable, pointing out the subjectivity involved in judgments of mental health.
  • His study was influenced by Labelling theory, highlighting the long-lasting effects of being labelled 'insane'.
  • His approach was also influenced by anti-psychiatry movement, which argued against the traditional medical approach to treating mental illness.
  • The study occurred at a time when there was increasing criticism of psychiatric institutions for violation of patient's rights and poor treatment conditions.

The Study Itself and Its Findings

  • Rosenhan conducted an experiment where 'pseudo-patients' feigned auditory hallucinations in order to be admitted to psychiatric hospitals.
  • Once admitted, the pseudo-patients behaved normally, but found it difficult to be discharged because their normal behaviour was interpreted as a symptom of their supposed mental illness.
  • This led Rosenhan to conclude that psychiatric labels were sticky and difficult to remove, which could lead to harmful self-fulfilling prophecies.
  • Rosenhan's study had profound implications for how psychiatry was understood and practiced, and catalysed changes in diagnostic practices and patient care.

Methodological Approach

  • Rosenhan employed a participant observation method, which allowed him to obtain data from inside the psychiatric hospitals.
  • Pseudo-patients were given the task to get themselves admitted into psychological hospitals by claiming to hear voices.
  • Once inside, they were instructed to behave as they normally would and to insist that they no longer heard voices.
  • Rosenhan's use of participant observation enabled him to challenge the validity of psychiatric diagnoses by showing how normal behaviours can be pathologised under the label of 'insanity'.

Comparisons of Carlsson’s work with Other Important Studies in the Field of Schizophrenia

Comparison with Davis and Kahn's Dopamine Hypothesis (1991)

  • Carlsson expanded on Davis and Kahn's dopamine hypothesis related to schizophrenia, which proposed an excess of dopamine receptors. However, Carlsson suggested it was not just dopamine, but also serotonin and glutamate that played crucial roles in the onset of schizophrenia.

  • While Davis and Kahn's approach was reductionist, focusing mainly on dopamine, Carlsson adopted a more holistic perspective involving multiple neurotransmitters.

Comparison with Javitt and Zukin's Glutamate Hypothesis (1991)

  • Javitt and Zukin proposed the glutamate hypothesis of schizophrenia, suggesting that deficient glutamate activity might be responsible for schizophrenic symptoms. Carlsson agreed to some extent but argued for a network interaction approach, stating that not only glutamate but also other neurotransmitters like dopamine and serotonin are essential in understanding schizophrenia.

Comparison with Meltzer's Serotonin Hypothesis (1989)

  • Meltzer proposed that serotonin played a significant role in schizophrenia. Carlsson agrees with this hypothesis but goes further by suggesting that interactions between serotonin, dopamine and glutamate are what lead to the symptoms of schizophrenia.

Comparison with Seeman's Antipsychotic Medication Hypothesis (1987)

  • Seeman suggested that antipsychotic medications worked by blocking certain dopamine receptors. Carlsson's research, however, expanded on this idea by looking at how these medications might work by affecting network interactions amongst a range of neurotransmitters.

Comparing Carlsson et al.'s Methodology with Other Studies

  • Carlsson et al. conducted an extensive review of pre-existing literature along with presenting some original research. This broad approach is both similar and different to the more narrowly focused studies such as those by Davis and Kahn, Javitt and Zukin, Meltzer and Seeman.

  • Carlsson's study focused on the interplay of multiple neurotransmitter systems, offering a more nuanced understanding of schizophrenia than most other research in this field.

In summary, Carlsson et al. took an integrated approach to the study of schizophrenia, looking at multiple neurotransmitter systems and their interactions. This adds a level of complexity to our understanding of schizophrenia and extends past theories that proposed single neurotransmitter involvement. It also opens up new avenues for the development of more effective antipsychotic medications.
