Mentalizing Based on External Features in Borderline Personality Disorder Compared With Healthy Controls: The Role of Attachment Dimensions and Childhood Trauma.

Extant research suggests that borderline personality disorder (BPD) is associated with impairments in mentalizing, that is, comprehending behavior in terms of underlying mental states. However, the precise nature of these impairments remains unclear. The literature is mixed concerning mental-izing based on external features of others, and specifically facial emotion recognition (FER) in BPD patients. This study investigated FER differences in 79 BPD patients and 79 matched healthy controls using the Reading the Mind in the Eyes Test (RMET). The authors also investigated attachment dimensions and childhood trauma in relation to mentalizing based on external features. Results showed that BPD patients performed worse on positive and negative emotions. Furthermore, avoidant attachment was negatively related to FER for neutral emotions, particularly in the control group. Trauma was negatively related to FER at trend level, particularly in BPD patients. The implications for this understanding of mentalizing based on external features in BPD are discussed.

The Relationship Between the Personality Inventory for the DSM-5 (PID-5) and the Psychotic Disorder in a Clinical Sample.

Recent studies have successfully investigated the validity of the DSM-5 Alternative Model for Personality Disorders. In a final sample of 174 psychiatric patients, the present study examined the relationship between the Personality Inventory for the DSM-5 (PID-5) and syndromal psychosis. Results showed that patients diagnosed with versus without a psychotic disorder significantly differed on all PID-5 domains except Antagonism. Discriminant function analysis indicated that lower Detachment, lower Negative Affect, lower Disinhibition, and higher Psychoticism best discriminated patients with a psychotic disorder from patients with other psychiatric conditions. Subsequent stepwise discriminant analysis on all facet scales of the contributing PID-5 domains revealed that higher Unusual Beliefs, lower Depressivity, and lower Distractibility contributed the most to this differentiation. PID-5 Psychoticism scores showed moderate correlations with current psychotic symptoms and were not influenced by dose of antipsychotic medication. Our results support the ability of the PID-5 to discriminate between patients with and without psychotic disorder.

Self-Reported Cognitive Biases Are Equally Present in Patients Diagnosed With Psychotic Versus Nonpsychotic Disorders.

We investigated the relation between subjective cognitive biases measured with the Dutch Davos Assessment of Cognitive Biases (DACOBS-NL) and (1) the presence of a psychotic versus nonpsychotic psychiatric disorder, (2) the current dose of antipsychotic medication and current psychotic symptoms, and (3) the Personality Inventory for the DSM-5 (PID-5) Psychoticism personality trait. Results showed that DACOBS-NL subjective cognitive biases (1) were equally present in patients diagnosed with nonpsychotic disorders compared with patients with a psychotic disorder, (2) could not be explained by the current dose of antipsychotic medication, nor by current psychotic symptoms, and (3) significantly correlated with all PID-5 Personality domains. Moreover, in predicting membership of the psychotic versus nonpsychotic psychiatric disorder group, the addition of the PID-5 domains in step 2 rendered the contribution of the DACOBS-NL subjective cognitive biases in step 1 nonsignificant. Further research is needed to clarify the interplay between cognitive biases and aberrant salience in the prediction of psychotic disorders.

DSM-5 section III personality traits and section II personality disorders in a Flemish community sample.

The Personality Inventory for DSM-5 (PID-5; Krueger et al., 2012) is a dimensional self-report questionnaire designed to measure personality pathology according to the criterion B of the DSM-5 Section III personality model. In the current issue of DSM, this dimensional Section III personality model co-exists with the Section II categorical personality model derived from DSM-IV-TR. Therefore, investigation of the inter-relatedness of both models across populations and languages is warranted. In this study, we first examined the factor structure and reliability of the PID-5 in a Flemish community sample (N=509) by means of exploratory structural equation modeling and alpha coefficients. Next, we investigated the predictive ability of section III personality traits in relation to section II personality disorders through correlations and stepwise regression analyses. Results revealed a five factor solution for the PID-5, with adequate reliability of the facet scales. The variance in Section II personality disorders could be predicted by their theoretically comprising Section III personality traits, but additional Section III personality traits augmented this prediction. Based on current results, we discuss the Section II personality disorder conceptualization and the Section III personality disorder operationalization.

What's in a face? Mentalizing in borderline personality disorder based on dynamically changing facial expressions.

The mentalization-based approach to borderline personality disorder (BPD) argues that impairments in mentalizing are a key feature of BPD. Most previous research in this area has concentrated on potential impairments in facial emotion recognition in BPD patients. However, these studies have yielded inconsistent results, which may be attributable to methodological differences. This study aimed to address several limitations of previous studies by investigating different parameters involved in emotion recognition in BPD patients using a novel, 2-step dynamically changing facial expression paradigm, taking into account the possible influence of mood, psychotropic medication, and trauma exposure. Twenty-two BPD patients and 22 matched normal controls completed this paradigm. Parameters assessed were accuracy of emotion recognition, reaction time (RT), and level of confidence, both for first and full response and for correct and incorrect responses. Results showed (a) that BPD patients were as accurate in their first, but less accurate in their full emotion recognition than normal controls, (b) a trend for BPD patients to respond more slowly than normal controls, and (c) no significant difference in overall level of confidence between BPD patients and normal controls. Mood and psychotropic medication did not influence these results. Exposure to trauma in BPD patients, however, was negatively related to accuracy at full expression. Although further research is needed, results suggest no general emotion-recognition deficit in BPD patients using a dynamic changing facial recognition paradigm, except for a subgroup of BPD patients with marked trauma who become less accurate when they have to rely more on controlled, reflective processes.

The Construct Validity of the Dutch Personality Inventory for DSM-5 Personality Disorders (PID-5) in a Clinical Sample.

The factor structure and the convergent validity of the Personality Inventory for DSM-5 (PID-5), a self-report questionnaire designed to measure personality pathology as advocated in the fifth edition, Section III of Diagnostic and Statistical Manual of Mental Disorders (DSM-5), are already demonstrated in general population samples, but need replication in clinical samples. In 240 Flemish inpatients, we examined the factor structure of the PID-5 by means of exploratory structural equation modeling. Additionally, we investigated differences in PID-5 higher order domain scores according to gender, age and educational level, and explored convergent and discriminant validity by relating the PID-5 with the Dimensional Assessment of Personality Pathology-Basic Questionnaire and by comparing PID-5 scores of inpatients with and without a DSM-IV categorical personality disorder diagnosis. Our results confirmed the original five-factor structure of the PID-5. The reliability and the convergent and discriminant validity of the PID-5 proved to be adequate. Implications for future research are discussed.
