Negative affect predicts social functioning across schizophrenia and bipolar disorder: Findings from an integrated...

Area of Science:

• Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• Serious mental illnesses often lead to functional impairment despite pharmacological treatments.
• Identifying predictors of functioning is crucial for improving patient outcomes.
• Negative affect is a key emotional construct that may impact social functioning.

Purpose of the Study:

• To investigate negative affect as a predictor of social functioning in individuals with serious mental illnesses.
• To compare negative affect levels between clinical populations and healthy controls.
• To determine if negative affect predicts social functioning independently of cognitive and symptom-related factors.

Main Methods:

• A cross-sectional study involving 404 participants, including individuals with schizophrenia, schizoaffective disorder, psychosis not otherwise specified, bipolar disorder, and healthy controls.
• Participants completed self-report measures of negative affect.
• Social functioning was assessed, and statistical analyses were performed to examine the relationship between negative affect and functioning.

Main Results:

• Clinical participants exhibited higher levels of negative affect compared to healthy controls.
• Negative affect measures were significantly correlated with social functioning in both clinical and control groups.
• Negative affect explained a significant portion of the variance in social functioning, even after controlling for cognition and positive/negative symptoms in clinical populations.

Conclusions:

• Elevated negative affect is a significant predictor of social functioning across serious mental illnesses.
• Treatments for serious mental illnesses should consider targeting negative affect in addition to cognitive and symptom-based interventions.
• Understanding and addressing negative affect can lead to improved functional outcomes.
