Language disturbance and functioning in first episode psychosis.

Area of Science:

• Psychiatry
• Neuroscience
• Clinical Psychology

Background:

• Language disturbance is a key feature of psychotic disorders, but its impact on functioning in first episode psychosis (FEP) needs more research.
• Both language and functioning can be assessed using clinician-rated and performance-based methods.

Purpose of the Study:

• To examine the concurrent associations between clinician-rated and performance-based measures of language disturbance and functioning in individuals with FEP.

Main Methods:

• 108 individuals with FEP were assessed using structured tools for formal thought disorder (FTD) dimensions and bizarre idiosyncratic thinking (BIT).
• Functioning was evaluated using performance-based instruments, clinician-rated scales, and real-world indicators.

Main Results:

• The disorganization dimension of FTD correlated significantly with clinician-rated occupational and social functioning.
• Bizarre idiosyncratic thinking (BIT) was significantly associated with performance-based functioning measures.
• Language disturbance showed limited predictive value for real-world functioning indicators.

Conclusions:

• Clinician-rated and performance-based assessments of language disturbance offer complementary insights into functioning in FEP.
• Communication disorders represent a potential intervention target in FEP, though longitudinal studies are needed.
