Background: In recent years, the existence of possible developmental pathways from childhood Attention-Deficit/Hyperactivity Disorder (ADHD) to adult Borderline Personality Disorder (BPD) has been suggested. The existence of common genetic factors has been described but there is little evidence on the role of environmental factors in the possible...

Background: Impairment in personality functioning (PF) represents a salient criterion of the DSM-5 alternative diagnostic model for personality disorders (AMPD). The main goal of this study is to analyze the relationship of the borderline personality disorder (BPD) clinical components derived from the DSM-5 categorical diagnostic model (affective...

Introduction: Cannabis is the illicit drug mostly widely consumed by adolescents in Spain. The understanding of consumption motives is an important factor for intervention. In Spain, there are no available instruments for their evaluation, hence, the goal of this paper is to study the psychometric properties of the Marihuana Motives Measure (MMM)...

Common environmental etiological factors between borderline personality disorder (BPD) and attention deficit/hyperactivity disorder (ADHD) have not been fully studied. The main aim of this study was to investigate the relationship between childhood trauma histories, assessed by the Childhood Trauma Questionnaire-Short Form (CTQ-SF), with adult BPD,...

Background and objectives Borderline Personality Disorder (BPD) is one of the most complex personality disorders (PD). The Borderline Personality Disorder Checklist (BPD Checklist) is an instrument specifically designed to assess the burden of BPD symptoms according to DSM-IV/5 criteria in the past month. Methods Our goal was to adapt and validate...

In recent years, both the prevalence of drug use and related child and adolescent psychiatric emergencies have risen sharply. There are few studies about the impact on child and adolescent emergency services. This study has a twofold aim. The first is to describe the prevalence of substance use disorders, mental disorders and dual diagnosis (substa...

Background: Discomfort in the postoperative period is common and may hinder patients' recovery. Factors causing postoperative discomfort have been identified, but a validated tool to assess postoperative discomfort is lacking. We aimed to evaluate the reliability and validity of an instrument designed to assess postoperative discomfort, the Postope...

Borderline Personality Disorder (BPD) has been associated with an intensive use of health resources and a high economic burden.

Introduction The available information on the cost of illness of Borderline Personality Disorder (BPD) is overtly insufficient for policy planning. Our aim was to estimate the costs of illness for BPD in Catalonia (Spain) for 2006. Methods This is a multilevel cross-design synthesis study combining a qualitative nominal approach, quantitative ‘top...

The hypothalamus-pituitary-adrenal axis (HPA) is essential in the regulation of stress responses. Increased methylation of the promoter region of the glucocorticoid receptor gene (NR3C1) has been described both in subjects with history of childhood trauma and in patients with Borderline Personality Disorder (BPD). However, no data on the possible a...

Aims and objectivesTo determine which unpleasant conditions might contribute to postoperative physical well-being, as judged by patients, nurses and physicians.Background Healthcare professionals have rarely assessed holistic postoperative well-being. Most studies have focused on specific symptoms, and a broader survey is lacking.DesignA prospectiv...

We studied the temporal stability of individual differences in the acquisition and generalization of fear. Seventy-one participants were tested in two almost identical fear-acquisition and fear-generalization sessions (separated by 8 months). Acquisition and generalization were measured by the fear-potentiated startle, the skin conductance response...

Although enhanced fear conditioning has been implicated in the origins of social anxiety disorder (SAD), laboratory evidence in support of this association is limited. Using a paradigm employing socially relevant unconditioned stimuli, we conducted two separate studies to asses fear conditioning in individuals with SAD and non-clinical individuals...

Previous studies have shown that individuals with anxiety disorders exhibit deficits in fear inhibition and excessive generalization of fear, but little data exist on individuals at risk from these disorders. The present study examined the role of trait anxiety in the acquisition and generalization of fear in 126 healthy participants selected on th...

No study so far has specifically addressed the influence of individual differences in trait-anxiety on aver-sive classical conditioning as indexed by the startle reflex response. We compared the startle reflex responses between participants classified as high (n = 25) and low (n = 26) in trait-anxiety while undergoing a single-cue aversive classica...

RESUMEN El trastorno límite de personalidad (TLP) es un trastorno psiquiátrico grave y difícil de tratar de un modo adecuado en el adulto, dada su heterogeneidad clínica y la diversidad de necesidades que puede presentar. Se ha evidenciado que el diagnóstico y tratamiento precoz puede mejorar el pronóstico del TLP, al evitar las complicaciones que...

This study assesses whether patients diagnosed with Borderline Personality Disorder (BPD) according to the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II) or the Revised Diagnostic Interview for Borderlines (DIB-R) present differences in factors associated with risk of poor outcome. Three hundred fifty-two patients were evaluat...

Dialectical behavior therapy (DBT) is an effective therapy. However, treating borderline personality disorder (BPD) patients with standard DBT can be problematic in some institutions due to logistical or cost limitations. The aim of this preliminary study is to examine the efficacy of Individual DBT in 37 BPD patients, compared with Combined indivi...

Few studies have investigated the role of the BDNF-val66met polymorphism in fear conditioning in humans, and previous results have been inconsistent. In the present study, we examined whether the BDNF-val66met was associated with differences in the acquisition and generalization of fear during a differential conditioning paradigm in a large sample...

The clinical heterogeneity and elevated comorbidity of Borderline Personality Disorder (BPD) have suggested the possible existence of several factors or subtypes of this construct. Studies published to date mainly show that this diagnosis could be represented either as a 1-dimensional model or 3-factor model. However, most of the studies have analy...

We examined the psychometric properties of the Spanish version of the self-report Personality Diagnostic Questionnaire-4+ (PDQ-4+) in a sample of 437 psychiatric outpatients. Psychometric properties were assessed through internal consistency analysis, exploratory factor analysis (EFA) and concurrent validity. Results indicate that the Spanish versi...

The diagnostic criteria for Borderline Personality Disorder (BPD) are heterogeneous, and include an admixture of personality traits, behaviours, and symptoms. The BPD DSM factor structure has been extensively studied, even though results are not consistent. In this study we performed a confirmatory factor analysis (CFA) to compare the five-factor m...

Personality is one of several factors that have been related to the initiation, maintenance and cessation of smoking. This paper aims to analyze the relationship between the alternative five-factor model of personality (AFFM), nicotine dependence (ND), nicotine use (NU) and cessation after twelve months of a cognitive-behavioral therapy combined wi...

Borderline personality disorder (BPD) is a severe psychiatric disorder that has a high clinical heterogeneity and frequent co-occurrence with other personality disorders (PDs).
