ObjectiveThe aims of this study were to explore the influence of personality disorders (PDs) in Spanish adolescents with Axis I psychiatric disorders on their use of mental health services and to analyze the risk of having a comorbid PD in relation to psychiatric service use.MethodsThe Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) and International Classification of Diseases, Tenth Revision (ICD-10) modules of the semistructured interview International Personality Disorders Examination were administered to a sample of 112 adolescent psychiatric patients (mean age = 15.8 years; SD, 0.8; range, 15-17; 79% women) at the point of initiating treatment. On the basis of the interview, subjects were divided into two groups: a PD group (PDG) and a non-PD group (NPDG). After 3 years of treatment, clinical records were retrospectively analyzed.ResultsThe PDG showed a significantly higher number of psychiatric admissions (P < .001), days per psychiatric admission (P < .001), and psychiatric emergencies (P < .010) than the NPDG, although the number of outpatient consultations was not significantly higher. Logistic regression analysis showed that the probability of belonging to the PDG rather than the NPDG increased with each psychiatric admission (odds ratio [OR] = 1.67 for DSM-IV criteria and OR = 1.59 for ICD-10 criteria), after controlling by sex, age, and comorbidity (Axis I disorders).ConclusionsPatients with comorbid PD used more inpatient and emergency psychiatric services than did patients without a PD. Large number of psychiatric hospitalizations suggests the likelihood of a PD being present.Copyright © 2012 Elsevier Inc. All rights reserved.
