A deficit of social cognition in bipolar disorder has been shown, even when patients are stable. This study compares the attribution of intentions (social-cognitive bias) in a group of 37 outpatients with bipolar disorder with 32 matched control subjects. Bipolar patients scored significantly higher in the Ambiguous Intentions Hostility Questionnaire, showing an angry and intentionality bias ( , ). Differences in blame scale and hostility bias did not reach statistical significance, but a trend was found ( ). Bipolar patients with depressive symptoms presented a higher score in the angry bias scale ( ) and aggressivity bias scale ( ). The global functioning (GAF) correlates significantly with intentionality ( ), angry ( ), and aggressivity ( ) biases. Bipolar patients show a social-cognitive bias that may play a role in their functional outcome.
