Beyond dysregulation: the role of emotion regulation strategies and impulsivity in borderline personality disorder severity

BEYOND DYSREGULATION: THE ROLE OF EMOTION REGULATION STRATEGIES AND IMPULSIVITY IN BORDERLINE PERSONALITY DISORDER SEVERITY

Cognitive reappraisal, expressive suppression, and impulsivity, rather than global emotional dysregulation, independently predict borderline personality disorder severity.

The aim was to examine the relative contributions of emotional dysregulation, emotion regulation strategies, and impulsivity to symptom severity in borderline personality disorder (BPD). In the methods, 40 outpatients diagnosed with BPD according to standard clinical criteria (age M = 25.4, SD = 4.3, range 18–34; 87.5% female, 12.5% male) were assessed using self-report scales (DERS, ERQ, BIS-11, and BSL-23); descriptive analyses were followed by Pearson correlations and multiple linear regression with BSL-23 as the dependent variable. Descriptive values were reported as 59.9 (14.1) for BSL-23, 78.0 (13.2) for BIS-11 total, 145.8 (18.6) for DERS total, 19.9 (5.0) for ERQ suppression, and 17.9 (5.0) for ERQ reappraisal; at baseline, 90% of patients were in the moderate, high, very high, or extremely high severity ranges. Correlation analyses showed that BSL-23 was associated with BIS-11 total, r = 0.647 (p < 0.001), ERQ suppression, r = 0.495 (p = 0.001), and ERQ reappraisal, r = -0.698 (p < 0.001), whereas DERS total was not significantly associated (r = 0.226, p = 0.161); among the DERS subscales, impulse control difficulties (impulse) showed the strongest trend (r = 0.270, p = 0.092), while lack of emotional awareness (awareness) showed the weakest (r = 0.099, p = 0.544). The regression model was significant (R2 = 0.643, adjusted R2 = 0.602, F(4,35) = 15.75, p < 0.001); in the model, ERQ reappraisal, B = -1.277 (0.353), p = 0.001 (β = -0.45), BIS-11 total, B = 0.324 (0.134), p = 0.021 (β = 0.30), and ERQ suppression, B = 0.697 (0.309), p = 0.030 (β = 0.25), were independent predictors, whereas DERS total was not significant (B = 0.034 (0.080), p = 0.671). In conclusion, cognitive reappraisal emerged as the strongest protective factor, while impulsivity and expressive suppression emerged as independent risk factors; limitations include the small sample and reliance on single-source self-report data, and the authors note the need for replication.
