An experimental investigation of mentalization ability in borderline personality disorder

Mediators in the Association Between Affective Temperaments and Suicide Risk Among Psychiatric Inpatients

BACKGROUND

Affective temperaments have been shown to be related to psychiatric disorders and suicidal behaviors. Less is known about the potential contributory role of affective temperaments on suicide risk factors. In the present study, we investigated whether the effect of affective temperaments on suicide risk was mediated by other variables, such as hopelessness, mentalization deficits, dissociation, psychological pain, and depressive symptoms.

METHODS

Several assessment instruments, including the Mini International Neuropsychiatric Interview (MINI); the Temperament Evaluation of Memphis, Pisa, and San Diego Autoquestionnaire (TEMPS-A); the Beck Hopelessness Scale (BHS); the Gotland Male Depression Scale (GMDS); the Dissociative Experiences Scale (DES); the Psychological Pain Assessment Scale (PPAS); and the Mentalization Questionnaire (MZQ), were administered to 189 psychiatrically hospitalized patients (103 women, 86 men) in Rome, Italy.

RESULTS

In single-mediator models, hopelessness, depressive symptoms, and mentalization, but not psychological pain or dissociation, were significant mediators in the association between prevalent temperament and suicide risk. In a multiple-mediator model, a significant indirect effect was found only for depression. Results demonstrated that patients with negative temperaments reported higher suicide risk, psychological pain, hopelessness, and depression, and less mentalization than patients with no prevalent temperament or hyperthymic temperaments.

CONCLUSIONS

Hopelessness, depression, and mentalization are all factors that mediate the relation between affective temperaments and suicide risk. Identifying factors that mediate the effects of affective temperamental makeup on suicide risk should enhance screening and intervention efforts.

Contrasting metacognitive, social cognitive and alexithymia profiles in adults with borderline personality disorder, schizophrenia and substance use disorder

Deficits in the ability to recognize and think about mental states are broadly understood to be a root cause of dysfunction in Borderline Personality Disorder (PD). This study compared the magnitude of those deficits relative to other forms of serious mental illness or psychiatric conditions. Assessments were performed using the metacognition assessment scale-abbreviated (MAS-A), emotion recognition using the Bell Lysaker Emotion Recognition Test and alexithymia using the Toronto Alexithymia Scale among adults with schizophrenia (n = 65), Borderline PD (n = 34) and Substance Use disorder without psychosis or significant Borderline traits (n = 32). ANCOVA controlling for age revealed the Borderline PD group had significantly greater levels of metacognitive capacity on the MAS-A than the schizophrenia group and significantly lower levels of metacognitive capacity than the Substance Use group. Multiple comparisons revealed the Borderline PD group had significantly higher self-reflectivity and awareness of the other's mind than the schizophrenia group but lesser mastery and decentration on the MAS-A than substance use group, after controlling for self-report of psychopathology and overall number of PD traits. The Borderline PD and Schizophrenia group had significantly higher levels of alexithymia than the substance use group. No differences were found for emotion recognition. Results suggest metacognitive functioning is differentially affected in different mental disorders.

Does reflective functioning mediate the relationship between attachment and personality?

Mentalization, operationalized as reflective functioning (RF), can play a crucial role in the psychological mechanisms underlying personality functioning. This study aimed to: (a) study the association between RF, personality disorders (cluster level) and functioning; (b) investigate whether RF and personality functioning are influenced by (secure vs. insecure) attachment; and (c) explore the potential mediating effect of RF on the relationship between attachment and personality functioning. The Shedler-Westen Assessment Procedure (SWAP-200) was used to assess personality disorders and levels of psychological functioning in a clinical sample (N = 88). Attachment and RF were evaluated with the Adult Attachment Interview (AAI) and Reflective Functioning Scale (RFS). Findings showed that RF had significant negative associations with cluster A and B personality disorders, and a significant positive association with psychological functioning. Moreover, levels of RF and personality functioning were influenced by attachment patterns. Finally, RF completely mediated the relationship between (secure/insecure) attachment and adaptive psychological features, and thus accounted for differences in overall personality functioning. Lack of mentalization seemed strongly associated with vulnerabilities in personality functioning, especially in patients with cluster A and B personality disorders. These findings provide support for the development of therapeutic interventions to improve patients' RF.

Experimental investigation of cognitive and affective empathy in borderline personality disorder: Effects of ambiguity in multimodal social information processing

Borderline personality disorder (BPD) is characterized by affective instability and interpersonal problems. In the context of social interaction, impairments in empathy are proposed to result in inadequate social behavior. In contrast to findings of reduced cognitive empathy, some authors suggested enhanced emotional empathy in BPD. It was investigated whether ambiguity leads to decreased cognitive or emotional empathy in BPD. Thirty-four patients with BPD and thirty-two healthy controls were presented with video clips, which were presented through prosody, facial expression, and speech content. Experimental conditions were designed to induce ambiguity by presenting neutral valence in one of these communication channels. Subjects were asked to indicate the actors' emotional valence, their decision confidence, and their own emotional state. BPD patients showed increased emotional empathy when neutral stories comprised nonverbally expressed emotions. In contrast, when all channels were emotional, patients showed lower emotional empathy than healthy controls. Regarding cognitive empathy, there were no significant differences between BPD patients and healthy control subjects in recognition accuracy, but reduced decision confidence in BPD. These results suggest that patients with BPD show altered emotional empathy, experiencing higher rates of emotional contagion when emotions are expressed nonverbally. The latter may contribute to misunderstandings and inadequate social behavior.

On the relationships between DSM-5 dysfunctional personality traits and social cognition deficits: A study in a sample of consecutively admitted Italian psychotherapy patients

This study aims at testing the hypothesis that the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) alternative model of personality disorder (AMPD) traits may be significantly associated with deficits on 2 different social cognition tasks, namely, the Reading the Mind in the Eyes Test and the Movie for the Assessment of Social Cognition, in a sample of consecutively admitted inpatients and outpatients. The sample was composed of 181 consecutively admitted participants (57.5% women; mean age = 38.58 years). Correlation coefficients and partial correlation coefficients were computed in order to assess the associations among social cognition tasks, DSM-5 AMPD traits, and dimensionally assessed DSM-5 Section II personality disorders. Specific maladaptive traits listed in the DSM-5 AMPD were significantly associated with Reading the Mind in the Eyes Test scores and Movie for the Assessment of Social Cognition scores, even when the effect of selected DSM-5 Section II personality disorders was controlled for. Our results support the relevance of studying social cognitive functioning in subjects suffering from personality disorders.

Exploring the effectiveness of combined mentalization-based group therapy and dialectical behaviour therapy for inpatients with borderline personality disorder - A pilot study

OBJECTIVES

Borderline personality disorder (BPD) is characterized by emotional instability, interpersonal dysfunction, and other features that typically develop before a background of insecure attachment and traumatic experiences. Dialectical behaviour therapy (DBT) has proven highly effective in reducing self-harm and improving emotion regulation, whereby problems concerning social cognition, which are also characteristic of BPD, may need additional approaches such as mentalization-based treatment (MBT).

METHODS

Here, we examined, in a pilot study, the effectiveness of MBT given adjunct to DBT, compared to DBT alone, in an inpatient sample with BPD, whereby mentalization was measured using a novel cartoon-based task.

RESULTS

Both treatments were highly effective in reducing symptom severity. The combination of DBT and MBT was superior in reducing fearful attachment and in improving affective mentalizing.

CONCLUSIONS

Mentalization-based treatment in combination with DBT may improve certain aspects of social cognitive skills and attachment security, as compared to DBT alone, although the exact mechanisms that led to these changes need to be studied further.

PRACTITIONER POINTS

Clinical implications Dialectical behaviour therapy (DBT) can usefully be combined with mentalization-based treatment (MBT). The combination of DBT and MBT reduces self-harm more than DBT alone. DBT plus MBT may lead to a reduction in fearful attachment and improvement of affective mentalizing. Short-term combinations of evidence-based borderline treatments may enrich psychiatric inpatient care. Therefore, such approaches deserve further research. Limitations The treatment condition was therapeutically more intense than the control condition. The study lacked a follow-up assessment. The impact of comorbid conditions on treatment response was not taken into account. Adherence to the manualized approach was not measured.

Self over time: another difference between borderline personality disorder and bipolar disorder

RATIONALE, AIMS AND OBJECTIVES

The nature of the relationship between bipolar disorder and borderline personality disorder has been an intense field of debate in the last two decades. Current diagnostic classifications approach this complex phenomenon using syndromatic definitions based on presence or absence of a restricted set of signs or symptoms that have demonstrated low specificity. One of the several utilities of the phenomenological method in psychiatry is to complement the clinical panorama, helping in the process of identifying potential differences between two separated clinical syndromes. The main objective of this publication is to explore one particular clinical difference between these two conditions - that is, the experience of self-continuity and time perception.

METHODS

the argument explored in this paper is based on previous second-person or phenomenological accounts of sufferers of both conditions.

RESULTS AND CONCLUSIONS

Whereas borderline personality disorder patients tend to experience only the present moment, referring frequent difficulties of drawing experiences of the past in order to determine their own future, bipolar disorder patients are constantly worried about the contradictions in their past experiences and the latent risk of losing control of themselves in future episodes of their disease. This contrast should be, however, corroborated in future research comparing directly the two groups in terms of the continuity of the self and their temporal structures.

Borderline Personality Disorder and Automatic Processing of Valence and Self-Other Relevance Information

BACKGROUND

Enhanced sensitivity to emotion stimuli and poor differentiation between self and others have been proposed to be important features of borderline personality disorder (BPD). Automatic processing of affective stimuli provides information about valence (positive vs. negative) and relevance of valence (self vs. other). The objectives of our study were to investigate the efficiency of automatic processing of valence and relevance at a semantic level in BPD compared to healthy individuals.

SAMPLING AND METHODS

A masked affective priming task, varying the valence and relevance of prime and target adjectives, was administered to 33 women with BPD and 33 healthy women. The forward and backward masked primes were shown for 50 ms. Subjects had the task of evaluating target words.

RESULTS

In the whole sample, a significant affective priming effect and a significant relevance priming effect occurred. BPD patients did not significantly differ from healthy individuals in affective priming or relevance priming after controlling for age, education, and intelligence. The presence of comorbid somatoform disorders was associated with increased affective priming and reduced relevance priming in BPD patients.

CONCLUSIONS

The efficiency of automatic recognition and the processing of valence information at a semantic level are not impaired in BPD. Moreover, BPD patients are able to perceive and differentiate automatically self- versus other-relevance during the perception of affective information like healthy controls. Thus, there is no evidence for enhanced sensitivity to emotion stimuli or poor differentiation between self and others in BPD at a very early stage of processing. The presence of somatoform disorders appears to influence affective as well as relevance priming in BPD.
