Negative symptoms, cognitive deficits (especially fluency and visual memory), and parkinsonism significantly impact community functioning in schizophrenia patients. These factors are key determinants of overall functional outcome.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Clinical Psychology

Background:

  • Schizophrenia significantly impacts community functioning.
  • Understanding determinants of functional outcome is crucial for treatment.

Purpose of the Study:

  • To investigate the impact of cognitive functioning, psychopathology, and extrapyramidal side effects on community outcome in Greek outpatients with schizophrenia.

Main Methods:

  • 40 outpatients with schizophrenia were assessed.
  • Quality of Life Scale (QLS) for social adjustment.
  • Positive and Negative Syndrome Scale (PANNS) for symptom severity.
  • Extrapyramidal Symptom Rating Scale (ESRS) for side effects.
  • Neuropsychological tests for cognitive domains (executive functioning, fluency, memory, attention, etc.).
