The influence of personality disorders on the use of mental health services in adolescents with psychiatric disorders

OBJECTIVE The 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. METHODS The 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. RESULTS The 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). CONCLUSIONS Patients 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.

Usefulness of the International Personality Disorder Examination screening questionnaire for borderline and impulsive personality pathology in adolescents

UNLABELLED The aim of this study was to analyze the usefulness of the International Personality Disorder Examination Screening Questionnaire (IPDE-SQ) for identifying DSM-IV and ICD-10 Borderline and Impulsive personality disorders (PD) in Spanish adolescents. METHOD The DSM-IV and ICD-10 IPDE-SQ screeners were used and compared with the diagnoses obtained with the IPDE semistructured interview in a sample of 125 adolescents treated in a psychiatric department. RESULTS For primary screening, the cutoff point with the best combination of sensitivity and specificity for ICD-10 impulsive and borderline PDs was obtained with three positive items, whereas for DSM-IV borderline the best PD cut-off was five positive items. For secondary screening, the best option would be one item above the cut-off points proposed for primary screening. CONCLUSION The 3-item cut-off point in the IPDE-SQ produces a high proportion of false positives on impulsive and borderline PDs in clinical adolescents. We propose several cut-off points, depending on whether the study is designed to perform primary or secondary screening.

Neither too much, nor too little. The dilemma of identifying personality disorders in adolescents patients with self-reports

The study aimed to compare methods of identification of Personality Disorders (PD) in adolescent patients with psychiatric disorders. A sample of 120 Spanish adolescents with clinical disorders was assessed using the International Personality Disorder Examination (IPDE) interview, its Screening Questionnaires (IPDE-SQ) comprising the ICD-10 and DSM-IV modules, and also the Temperament Character Inventory (TCI) to identify risk of PD. The IPDE-SQ identified a risk of PD around 92-97% of the sample; 61.7% when adjusting the stricter cut-off points. The TCI showed a PD risk of 20%, whereas the prevalence of PD identified by the IPDE clinical interview was around 36-38%. The differences between the IPDE, IPDE-SQ and TCI were significant, and a low agreement among instruments was obtained. Large discrepancy between self-report instruments in identifying PD with regard to the clinical interview raises several questions concerning the use of these instruments in clinical settings on adolescents with psychiatric disorders.

Mental Health Problems and Victimization in Adolescents

Poly-victims are described as subjects who experience extremely high levels of victimization. This condition is regularly associated with wide psychopathological distress. Children and adolescents are special risk collective for this type of victimization. Objective To describe and analyze more frequents mental health problems in adolescents with different levels of victimization. Method A community sample of 895 adolescents (M = 15.7; SD=1.3 years old) was subdivided into several groups taking as reference the number of victimizations suffered in the last year, obtained from the Juvenile Victimization Questionnaire . Resulting groups were as follows: those adolescents presenting no type of victimization, the group below average, a group above average and the group of poly-victimized adolescents. Mental health problems were identified with the Youth Self Report , analyzing specifically the DSM syndrome scales. Results The group of poly-victimized adolescents presented more significant ( p Conclusions Poly-victimization in adolescents is associated to larger symptomatology patterns and mental health problems development.

P01-225 - Hospital admissions and personality pathology in adolescents with psychiatric disorders

The use of psychiatric services has been associated with a wide range of clinical variables. However, information about the impact of adolescent personality pathology related to hospital admissions is limited. Objective To analyze the different combination of personality pathology associated to variables of psychiatric hospital admissions (number of admissions, total of days spent as psychiatric inpatient, average of days for admission, and number of admissions in a day care hospital). Method The ICD-10 and DSM-IV modules of the semi-structured interview IPDE (International Personality Disorders Examination) were administered, in a sample of 107 adolescent psychiatric patients (M=15.8, SD=0.8 years old; age rank 15-17; 79% female). Results Personality pathology group identified by the IPDE showed significantly higher number (p Conclusion Patients with psychotic disorders or complex PD were the highest users of inpatients services, but not of day care hospital admissions.

PW01-234 - Severity of adicction and PSY-5 traits in adolescents with substance use disorders

The objective of this study was to examine the association of different personality traits on severity of addiction indexes and patterns of drug use level, in a sample of adolescent psychiatric patients with Substance Use Disorders (SUD), based on the dimensional model of Personality Psychopathology Five (PSY-5) of the MMPI-A. Method The Teen Addiction Severity Index (T-ASI), the MMPI-A, and an inventory of drug use pattern were administered to 73 psychiatric patients (M=16.0, SD=1.18 years old; 51% male). Results Rho Spearman correlations showed significant associations between Disconstraint (DISC) and T-ASI indexes of drug and social problems (rho= .342, p= .003, and rho= .320, p= .006) and also between DISC in relation to level of cannabis use and other drugs than cocaine and amphetamines (rho= .334, p= .004, and rho= .274, p= .023). The dimension of Psychoticism (PSYC) and Aggressiveness (AGGR) showed slight association with cannabis use (rho= .236, p= .045, and rho= .247, p= .035). The Negative emotionality (NEGE) and Introversion (INTR) showed a moderate association with the T-ASI index of psychiatric problems (rho= .265, p=0.023, and rho=.256, p= .029) but not with drug problems. Conclusions The DISC trait could represent a good indicator of risk for drug related problems. High scores in PSYC and AGGR are slightly associated to increase level of cannabis use. While psychiatric complaints are associated with NEGE and INTR traits.
