Social functioning impairments are common in bipolar disorder, particularly during depressive episodes. Impaired social competence worsens the impact of depression and cognitive deficits on real-world functioning.
Area of Science:
- Psychiatry
- Neuroscience
- Clinical Psychology
Background:
- Social functioning deficits are prevalent in bipolar disorder, often assessed via self-reports.
- Objective measures of social competence and functioning are needed to understand bipolar disorder's impact.
Purpose of the Study:
- To evaluate performance-based and observer-based social functioning in bipolar disorder.
- To determine the influence of symptoms and neurocognition on social functioning.
Main Methods:
- Cross-sectional study of 164 bipolar disorder patients.
- Utilized Social Skills Performance Assessment (SSPA) and Specific Level of Functioning (SLOF)-Interpersonal subscale.
- Assessed neurocognitive tests, depression, and manic symptoms.
Main Results:
- 29% showed performance-based social impairment (SSPA), 64% had observer-rated deficits (SLOF).
- Neurocognition correlated with both performance and observer-rated social functioning.
- Depression was the strongest predictor of social functioning, especially when social competence was impaired.
Conclusions:
- Bipolar depression significantly impairs social functioning.
- Impaired social competence exacerbates the negative effects of depression and cognitive deficits on functioning in bipolar disorder patients.
