Rosenhan Study on Insanity and Diagnosis

Apr 24, 2025

Rosenhan 1973 Study - Clinical Psychology

Study Overview

  • Aim: Investigate whether sane individuals can be distinguished from the insane.
  • Design: Field experiment using independent groups.
    • Independent Variable: Schizophrenic symptoms displayed by pseudopatients.
    • Dependent Variable: Diagnostic label assigned.
    • Method: Participant observation.

Sample

  • 8 sane volunteers (3 women, 5 men).
  • Conducted in 12 psychiatric institutions across 5 US states.

Procedure

  • Pseudopatients faked auditory hallucinations (e.g., feeling "empty," hearing "thud" or "hollow").
  • Used false names and jobs but truthful personal histories.
  • All but one diagnosed with schizophrenia; one with manic depression.
  • Once admitted, pseudopatients acted normally and observed staff treatment.
  • Secretly disposed of medication given.

Findings

  • None of the pseudopatients were detected by hospital staff.
  • Hospitalization lasted 7 to 52 days (average 19 days).
  • 35 of 118 real patients suspected pseudopatients were faking.
  • Normal behaviors were misinterpreted as signs of mental illness:
    • Note-taking labeled as "writing behavior."
    • Walking in corridors seen as nervousness.
    • Waiting early for lunch interpreted as an "oral acquisitive syndrome."
  • Minimal interaction with staff:
    • Nurses spent 90% of time in their offices.
    • Average staff-patient interaction less than 7 minutes/day.
    • 70% of pseudopatients ignored, 23% received eye contact, 2% received verbal responses.
  • Common experiences of powerlessness and depersonalization:
    • Lack of rights, privacy, and engagement.
    • Verbal and physical mistreatment reported.

Evaluation

Strengths

  • Standardized Procedure: High reliability due to identical training for pseudopatients.
  • Generalizability: Varied hospital types and locations enhance findings' generalizability.
  • Reliability: Consistent findings across multiple hospitals.

Weaknesses

  • Validity Issues: Diagnoses based on classic schizophrenia symptoms make misdiagnosis unsurprising.
    • In a follow-up study, pre-warned hospitals mistakenly suspected real patients as fakes.
  • Ethical Issues: Deception and potential harm due to pseudopatients occupying space for real patients.

Supporting and Contradicting Studies

  • Supporting:
    • Laurence Stein (2004): Similar misdiagnosis in nine emergency rooms, supporting Rosenhan's findings.
  • Contradicting:
    • Spitzer et al. (2005): Many psychiatrists ruled out psychotic behavior, arguing Rosenhan's exaggeration.

Conclusion

  • Diagnosis influenced by context; behaviors interpreted according to expectations.
  • Diagnostic processes deemed unreliable; psychiatric labels can lead to self-fulfilling prophecies.
