Social cognitive problem-solving in schizophrenia: associations with fluency and verbal memory

Area of Science:

• Neuroscience
• Psychiatry
• Cognitive Psychology

Background:

• Social functioning is crucial for individuals with schizophrenia.
• Social cognitive problem-solving (SCPS) impacts social competence and interpersonal interactions.
• Understanding the link between SCPS and neurocognition is vital for schizophrenia treatment.

Purpose of the Study:

• To investigate the relationship between social functioning and neurocognitive function in schizophrenia.
• To assess social cognitive problem-solving (SCPS) abilities in schizophrenia patients compared to healthy controls.
• To explore the association between SCPS and specific neurocognitive domains, including verbal memory, executive function, and divergent thinking.

Main Methods:

• 49 schizophrenia patients and 28 healthy controls participated.
• Neurocognitive assessment included the Means-Ends Problem-Solving Procedure (MEPS) for SCPS, Rey Auditory Verbal Learning Test (RAVLT), Wisconsin Card Sorting Test (WCST), and fluency tests.
• Clinical assessment utilized the Positive and Negative Syndrome Scale (PANSS) and Global Assessment of Functioning (GAF).

Main Results:

• Schizophrenia patients demonstrated significantly poorer MEPS performance than healthy controls.
• In patients with normal RAVLT (verbal memory) scores, MEPS scores correlated with fluency test responses (divergent thinking).
• No significant correlation was found between MEPS scores and WCST (executive function) scores in this subgroup.

Conclusions:

• Social cognitive problem-solving (SCPS) is significantly impaired in individuals with schizophrenia.
• SCPS is associated with divergent thinking, particularly concept flexibility and viewpoint conversion, in schizophrenia patients with preserved verbal memory.
• These findings suggest that interventions targeting divergent thinking may improve SCPS and social functioning in schizophrenia.
