Background:

Borderline personality disorder (BPD) is characterized by interpersonal difficulties, emotional instability, identity disturbances, and cognitive issues.
Cognitive dysregulation, including catastrophizing and rumination, is implicated in the emotional dysregulation seen in BPD.
Prior research indicated thought suppression fully mediates the link between negative affect and BPD symptoms.

Purpose of the Study:

To investigate whether catastrophizing also mediates the relationship between negative affect intensity/reactivity and BPD symptoms.
To explore the role of cognitive factors in the development and maintenance of BPD.

Main Methods:

Two independent samples were recruited: university students (N=191) and Amazon Mechanical Turk (MTurk) participants (N=172).
Participants completed online questionnaires assessing negative affect, catastrophizing, and BPD symptoms.
Mediation analyses were conducted to examine the proposed relationships.

Main Results:

Catastrophizing was found to partially mediate the relationship between negative affect intensity/reactivity and BPD symptoms.
The findings suggest that catastrophizing plays a significant role in understanding BPD, similar to rumination.

Conclusions:

Catastrophizing is an important cognitive mechanism contributing to BPD symptoms.
These results underscore the clinical relevance of addressing catastrophizing in BPD treatment.
Future research should further explore cognitive mediators and intervention targets for BPD.
