Social domain dysfunction and disorganization in borderline personality disorder

Area of Science:

• Psychiatry
• Clinical Psychology
• Social Neuroscience

Background:

• Social dysfunction in personality disorders is often attributed to temperamental traits.
• This study explores the role of social processing deficits in personality disorders.
• Investigates if borderline personality disorder (BPD) and avoidant personality disorder (APD) differ in social domain deficits.

Purpose of the Study:

• To differentiate BPD and APD based on social processing deficits.
• To determine if disorganized social functioning uniquely characterizes BPD.

Main Methods:

• Recruited patients from psychiatric clinics in Pittsburgh, USA.
• Included groups with BPD, APD, and no personality disorder (no-PD).
• Utilized standardized assessments for Axis I/II disorders and social domain dysfunction, including a new 'domain disorganization' (DD) scale.

Main Results:

• Pervasive social dysfunction significantly increased the odds of Axis II disorders.
• Both APD and BPD showed elevated social dysfunction.
• Romantic relationship dysfunction was specifically linked to BPD symptoms and diagnosis; DD correlated with BPD diagnosis and symptom severity.

Conclusions:

• Interpersonal properties of personality disorders offer insights into disorder origins and maintenance.
• BPD is associated with disturbances in romantic relationships, suggesting a role for attachment processes.
• BPD is characterized by disorganized functioning across social domains.
