Examining the relationship between emotion regulation deficits and borderline personality disorder features: A daily diary study

This study used a six-day daily diary methodology to precisely specify the nature of emotion regulation deficits associated with borderline personality disorder (BPD) features. Three possibilities were explored: that BPD features are associated with (1) the overall underuse of emotion regulation strategies; (2) the overuse of dysfunctional and the underuse of functional strategies; and (3) the lower perceived effectiveness of emotion regulation strategies. One hundred and fifty-four undergraduate participants completed self-report measures of BPD feature severity, and then reported their daily negative emotional intensity, whether or not they used various emotion regulation strategies, and whether or not the strategies that they used were effective across a six-day period. Higher BPD features were associated with (a) higher total frequency use of emotion regulation strategies; (b) higher frequency use of dysfunctional and functional emotion regulation strategies; and (c) less self-reported effectiveness of functional strategies. BPD features may be characterized by increased attempts to regulate emotions, without corresponding increases in perceived effectiveness.
