Real-World Functioning in Psychiatric Outpatients: Predictive Factors

Area of Science:

• Psychiatry
• Clinical Psychology
• Mental Health Research

Background:

• Limited research exists on predictors of real-world functioning in psychiatric disorders beyond schizophrenia.
• Understanding these predictors is crucial for improving patient outcomes across diverse diagnoses.

Purpose of the Study:

• To identify clinical, socio-demographic, and illness-related predictors of real-world functioning.
• To examine these predictors over 12 months of standard treatment in outpatients with schizophrenia, major depressive disorder, bipolar disorder, and borderline personality disorder.

Main Methods:

• A cohort of 1019 outpatients with schizophrenia, major depressive disorder, bipolar disorder, and borderline personality disorder were assessed.
• Standardized tools including SCID-5-CV, SCID-5-PD, CGI-S, SAT-P, DAI-10, and PSP were used.
• Multiple regression analysis examined the change in the Personal and Social Performance (PSP) scale over 12 months.

Main Results:

• Higher baseline PSP scores and achieving milestones predicted better functioning, except in bipolar disorder.
• In the overall sample, age of onset, treatments, and quality of life predicted functioning, while psychiatric history and global symptoms were inversely related.
• Specific predictors varied by diagnosis, with factors like adherence, psychotherapy, and medication influencing outcomes differently.

Conclusions:

• Socio-demographic and illness-related variables are significant predictors of functional improvement.
• Psychopathology and disease severity alone do not fully account for changes in real-world functioning.
• Tailored treatment approaches considering these diverse predictors may enhance functional recovery in psychiatric outpatients.
