Negative evaluation bias for positive self-referential information in borderline personality disorder

Area of Science:

• Psychology
• Clinical Psychology
• Cognitive Neuroscience

Background:

• Borderline personality disorder (BPD) is associated with altered self-related information processing.
• Experimental evidence on dysfunctional self-referential processing in BPD is limited.

Purpose of the Study:

• To investigate self-referential information processing biases in BPD.
• To examine the relationship between these biases and attributional style or depressive mood.

Main Methods:

• Thirty BPD patients and 30 healthy controls judged word valence under self-referential, other-referential, or no context.
• Free recall and recognition tasks assessed memory performance.

Main Results:

• BPD patients showed a negative evaluation bias for positive/neutral words with self-reference or no context.
• This bias correlated with negative attributional style in BPD, not depression.
• No differences in recall or recognition memory were observed between groups.

Conclusions:

• BPD involves a negative evaluation bias for self-referential information, particularly positive stimuli.
• This perceptual bias may link to negative self-attributions in daily life for BPD patients.
• The bias does not appear to impair memory encoding or retrieval.
