To study the association of dissociative symptoms and specific psychopathological dimensions in a sample of patients with Borderline Personality Disorder (BPD).

An observational analytic study was conducted. Patients with BPD were administered the Diagnostic Interview for Borderline (DIB-R) and Dissociative Experience Scale (DES–II).

Participants were 34 adult patients with BPD. The majority presented with dissociative symptoms (65.6%; n = 21). A statistical significant correlation was found between DES total score and DIB-R subscales: depression (P = 0.04), feeling of loneliness and emptiness (P = 0.005), sexual deviation (P = 0.002) and intolerance to loneliness (P = 0.01). Furthermore, depersonalization was statistically correlated with the severity of borderline psychopathology (DIB-R total score- P = 0.04), suicidal behavior (P = 0.001) and interpersonal problems (P = 0.04). Derealization was significantly correlated with cognition (P = 0.02), psychotic thought (P = 0.004) and intolerance to loneliness (P = 0.02).

Dissociative symptoms are not easy to detect in the clinical daily work. More than a half of patients with BPD presented with dissociative symptoms detected with a specific rating scale. Particularly, only some specific psychopathological dimensions are correlated with dissociation and need to be assessed in patients with BPD.
