1. What is a major clinical flaw with the classification of SZ as a disorder?

  • Individuals with the disorder will vary substantially on most features as SZ is a heterogeneous clinical syndrome
  • Individuals with the disorder will either show positive (Symptoms such as hallucinations/delusions) or negative symptoms (negative/flat affect, catatonia)
  • Individuals with the disorder don't tend to vary, the disorder is homogeneous
