Schizophrenia patients show deficits in generating multiple solutions, impacting neurocognitive function. Alternative thinking, though not directly linked to social functioning, correlates with verbal fluency and attention.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Cognitive Psychology

Background:

  • Schizophrenia is associated with significant social and cognitive impairments.
  • Understanding the relationship between neurocognitive deficits and social functioning is crucial for treatment.

Purpose of the Study:

  • To investigate the link between clinical social functioning measures and neurocognitive test results in schizophrenia patients.
  • To assess alternative thinking abilities using the Optional Thinking Test (OTT) and its correlation with other cognitive and social measures.

Main Methods:

  • A cohort of 36 schizophrenia patients and 25 healthy controls were assessed.
  • Neurocognitive functions were evaluated using MMSE, RAVLT, LCT, fluency tests, and OTT.
  • Clinical measures included PANSS, GAF, SFS, and LASMI-I.

Main Results:

  • Schizophrenia patients demonstrated poorer performance on most neurocognitive tests, including the OTT.
  • Alternative thinking (OTT) correlated with verbal fluency and attention, but not with social functioning scores (GAF, SFS, LASMI-I).
  • Patients could generate similar categories of alternatives but fewer in number compared to controls.

Conclusions:

  • Schizophrenia patients exhibit reduced quantity but not diversity in alternative thinking.
  • Alternative thinking deficits may be linked to specific cognitive impairments like attention and verbal fluency, rather than directly to social functioning.
