Abstract:
Identity disturbance is a key criterion in defining borderline personality disorder (BPD). This symptomatic criterion occupies a central place from the dimensional perspective for the rest of the personality disorders in the new DSM-5 proposal. Identity Disturbance Questionnaire (IDQ) (Wilkinson-Ryan & Westen, 2000) is a hetero-applied questionnaire that assesses four dimensions of disturbed identity: role absorption, painful incoherence, inconsistency, and lack of commitment. The objective of this work has been to translate, adapt and validate the American version of the IDQ into Spanish, and to analyze the relationship between identity disturbance with clinical symptoms of BPD, its general symptoms, comorbidity with other personality disorders and with her history of child abuse. The sample consisted in 36 women diagnosed with BPD and 195 non-patient subjects. The Spanish version of the IDQ has shown reliability and validity. The four-factor model is still the most suitable to explain the scale construct. The presence of identity disturbance appears by the IDQ in the BPD implies role confusion, suffering due to a sense of incoherence and inconsistency in thoughts, as well as behaviors and lack of vocational and occupational commitment. A greater of identity disturbance implies a greater presence of strange thoughts and unusual perceptual experiences, non-delusional paranoids, and pseudo-psychotic and greater presence of depression, anxiety, irritability and other dysphoric states. Identity disturbance implies greater comorbidity with passive-aggressive, paranoid, depressive, schizoid and schizotypal personality traits, and to a lesser extent narcissistic and avoidant, as well as more symptoms of interpersonal sensitivity, hostility, paranoid ideation, psychoticism and obsessions.
A history of abuse in childhood, specifically emotional, physical and sexual abuse and emotional and physical neglect, have been linked to identity disturbance.
