Long-lasting symptoms in borderline personality disorder: Defining an emergent population with differential clinical and therapeutic features.

Although the clinical symptoms of borderline personality disorder (BPD) tend to remit over time, a substantial proportion continues to present "long-lasting symptoms" (LLS). This term refers to individuals who present some degree of clinical improvement, but low mood, feelings of emptiness, and poor psychosocial adjustment typically persist. The aim of this study was to compare the sociodemographic, clinical, and therapeutic variables in individuals with BPD with and without LLS. A total of 620 participants with BPD were included and subdivided into two groups: non-LLS group (n = 549, mean age = 28.02 [6.1] and range, 18-40 years) and LLS group (n = 71, mean age = 44.69 [3.6] and range, 41-56 years). The groups were compared in sociodemographic, clinical, and drug treatment characteristics. We also evaluated the impact of dialectical behavioral therapy-skills training (DBT-ST) on polypharmacy. The prevalence of individuals with long-lasting BPD symptoms increased significantly over a 20-year period (from <1% to 16%). The LLS group was characterized by less clinical severity, higher comorbidity with affective disorders but lower comorbidity with eating disorders, more disability, and more medication taking. Patients with LLS who received DBT-ST experienced a significant decrease in the use of benzodiazepines and the number of medications prescribed compared with those who did not receive DBT-ST. Clinicians should be aware of the specific features of older patients with BPD in order to better identify and address their specific therapeutic needs.

Physical health, primary care utilization and long-term quality of life in borderline personality disorder: A 10-year follow-up study in a Spanish sample.

OBJECTIVE: We aimed to study physical health and primary care utilization in the long-term course of borderline personality disorder (BPD) and their impact on quality of life (QOL) in a Spanish clinical sample. METHODS: This study is part of a longitudinal study following a clinical cohort with BPD. A total of 41 participants were re-evaluated at 10-year follow-up, when current medical conditions, primary care utilization, and quality of life were assessed. Comparative population data were extracted from the Catalan Health Survey ESCA. RESULTS: 68% of BPD patients reported physical health problems, and 32% informed of multiple medical illnesses at follow-up. Higher rates of musculoskeletal disorders and frequent use of general practitioner (GP) consultations were reported by BPD patients compared to the general population. Differences in physical health and use of primary care services between remitted and non-remitted BPD patients were not significant. BPD remission was independently associated with better long-term QOL. Comorbid somatic diseases worsened the long-term QOL of non-remitted BPD patients. CONCLUSION: Chronic somatic conditions are prevalent in people with BPD and interact negatively with persistent BPD pathology, worsening their QOL in the long-term. Health care strategies in the assistance of long-lasting BPD patients are recommended.

Non-suicidal self-injury in young adults with and without borderline personality disorder: the role of emotion dysregulation and negative urgency / Autolesión no suicida en adultos jóvenes con y sin trastorno límite de la personalidad: el papel de la desregulación emocional y la urgencia negativa

La Autolesión No Suicida (ANS) se define como un dolor auto-infligido que se utiliza como un mecanismo para aliviar la angustia psicoló-gica. Aunque ANS es común en el trastorno límite de la personalidad (TLP), también es un problema creciente en estudiantes universitarios. Si bien la desregulación emocional y la urgencia negativa están asociadas con ANS, poco se sabe sobre las dimensiones específicas que predicen la moti-vación (funciones) y la frecuencia de las autolesiones. Se exploró la relación entre la desregulación emocional, la urgencia negativa, y ANS en 86 adultos jóvenes, divididos en tres grupos: estudiantes universitarios con ANS, pa-cientes TLP con ANS y un grupo de control sano sin ANS. Realizamos análisis de regresión múltiple para predecir las funciones y frecuencia de ANS. La no aceptación de las emociones, una dimensión especifica de la desregulación emocional, predijo de manera única las funciones intraperso-nales de ANS, pero no las funciones interpersonales. Por último, la falta de estrategias de regulación emocional predijo la frecuencia de ANS solo en individuos con una alta urgencia negativa, es decir, individuos que tienden a actuar impulsivamente cuando experimentan emociones negativas, pero no en aquellos con una baja urgencia negativa. Los hallazgos resaltan las moti-vaciones subyacentes a la autolesión y revelan facetas de la desregulación emocional relevantes para el tratamiento de ANS.(AU)

Non-suicidal self-injury (NSSI) is defined as self-inflicted pain, and it is used as a mechanism to alleviate psychological distress. Although NSSI is prevalent in Borderline Personality Disorder (BPD), it is also an increasing concern among college student populations. While emotion dysregulation and negative urgency are associated with NSSI, little is known about which dimensions specifically predict the motivations (NSSI-functions) and frequency of self-harm. The current study explored the rela-tionship between emotion dysregulation, negative urgency, and NSSI in 86 young adults, divided into three groups: college students with NSSI, BPD patients with NSSI, and a healthy control group without NSSI. We con-ducted multiple regression analyses to predicted NSSI-functions and NSSI-frequency. Non-acceptance of emotions, a specific dimension of emotion dysregulation, uniquely predicted intrapersonal NSSI-functions (e.g., regu-lating distressing emotions), but not interpersonal NSSI-functions (e.g., communicating distress). Lastly, poor emotion regulation strategies pre-dicted NSSI-frequency only in individuals with high negative urgency, that is, individuals who tend to act impulsively when experiencing negative emotions, but not in those with low negative urgency. Findings shed light on the underlying motivations for engaging in self-injury, and they reveal facets of emotion dysregulation relevant for NSSI treatment.(AU)

Pharmacological Management of Borderline Personality Disorder and Common Comorbidities.

Comorbidity between borderline personality disorder (BPD) and other mental disorders is common. Although no specific pharmacological treatments have been approved for the treatment of BPD, many drugs, including antidepressants such as selective serotonin reuptake inhibitors (SSRIs), mood stabilizers, second-generation antipsychotics, and even benzodiazepines, are routinely prescribed off label. Nonetheless, recommendations for off-label drugs in these patients are highly varied, with a notable lack of agreement among clinical guidelines. The most common reason for pharmacological treatment and polypharmacy in these patients is comorbidity with other psychiatric disorders. In this context, we reviewed major clinical guidelines and the available data on pharmacotherapy in patients with BPD to develop practical recommendations to facilitate decision-making in routine clinical practice, thus helping clinicians to select the optimal therapeutic approach in patients with BPD who have comorbid disorders. This review confirmed that no clear recommendations for the pharmacological treatment are available in clinical guidelines. Therefore, based on the available evidence, we have developed a series of recommendations for pharmacotherapy in patients with BPD who present the four most common comorbidities (affective, anxiety, eating, and drug use disorders). Here, we discuss the recommended treatment approach for each of these comorbid disorders. The prescription of medications should be considered only as an adjunct to BPD-specific psychotherapy. Polypharmacy and the use of unsafe drugs (i.e., with a risk of overdose) should be avoided. Our review highlights the need for more research to provide more definitive guidance and to develop treatment algorithms.

"Skills for pills": The dialectical-behavioural therapy skills training reduces polypharmacy in borderline personality disorder.

OBJECTIVE: Polypharmacy and overprescription of off-label medications are common in patients with borderline personality disorder (BPD). The aim of the present naturalistic study was to explore whether the skills training module of dialectical-behavioural therapy (DBT) can reduce polypharmacy in these patients in routine clinical practice. METHODS: Retrospective, observational study of 377 patients with a primary diagnosis of BPD consecutively admitted to the BPD outpatient unit from 2010 through 2020. All patients were invited to participate in the DBT skills training module (DBT-ST). DBT-ST participants (n = 182) were compared with a control group who did not participate in DBT-ST (n = 195). Pre-post intervention changes in medication load and use of antidepressants, benzodiazepines, mood stabilizers, and antipsychotics were evaluated. RESULTS: At baseline, most patients (84.4%) were taking at least one medication and 46.9% were on polypharmacy. Compared to controls, patients in the DBT-ST group presented a significant reduction in the number of medications (2.67-1.95 vs. 2.16-2.19; p < 0.001), medication load (4.25-3.05 vs. 3.45-3.48; p < 0.001), use of benzodiazepines (54.4%-27.5% vs. 40%-40.5%; p < 0.001), mood stabilizers (43.4%-33% vs. 36.4%-39.5%; p < 0.001), and antipsychotics (36.3%-29.1% vs. 34.4%-36.9%; p < 0.001). CONCLUSIONS: These findings suggest that patients with BPD can benefit from the DBT-ST module, which may reduce the medication load, particularly of sedatives. The results suggest that DBT-ST may be useful to treat overmedication in patients with BPD and could help to promote "deprescription" in clinical practice.

A Functional Connectivity Study to Investigate the Role of the Right Anterior Insula in Modulating Emotional Dysfunction in Borderline Personality Disorder.

OBJECTIVE: Previous imaging studies in patients with borderline personality disorder (BPD) have detected functional brain dysfunctions. Mindfulness training may improve the symptoms of BPD, although the neural mechanisms involved remain poorly understood. This study had several key aims: a) to investigate the role of right anterior insula (rAI) functional connectivity in modulating baseline emotional status in BPD, b) to compare differences in connectivity changes after mindfulness training versus interpersonal effectiveness intervention, and c) to explore the correlation between longitudinal changes in imaging data and clinical indicators. METHODS: Thirty-eight patients with BPD underwent resting-state functional magnetic resonance imaging. Participants completed self-report clinical scales and participated in a dialectical-behavioral therapy (mindfulness versus interpersonal effectiveness modules). Changes in clinical and imaging variables were evaluated longitudinally after completion of the first 10-week sessions of psychotherapeutic intervention. RESULTS: At baseline, the rAI was strongly connected with the other salience network nodes and anticorrelated with most core nodes of the default mode network (p < .05, corrected). The functional connectivity of the rAI correlated with emotional dysregulation and deficits in mindfulness capacities (p < .05, corrected). After completion of psychotherapeutic intervention, both groups (mindfulness and interpersonal effectiveness) showed divergent posttherapy functional connectivity changes, which were in turn associated with the clinical response. CONCLUSIONS: The functional connectivity of the rAI seems to play an important role in emotion dysregulation and deficits in mindfulness capacities in individuals with BPD. Psychotherapy seems to modulate this functional connectivity, leading to beneficial changes in clinical variables.

Ayahuasca may help to improve self-compassion and self-criticism capacities.

OBJECTIVE: Ayahuasca is a psychedelic brew that originated in the Amazon basin. The psychological effects of this drug are becoming better understood due to the growing research interest in identifying new potential therapeutic agents for the treatment of emotion dysregulation and other disorders. Previous studies suggest that ayahuasca enhances mindfulness-related capacities (decentering, non-judging, non-reacting and acceptance) and emotion regulation. The aim of the present exploratory study was to determine the effects of ayahuasca on self-compassion in a community sample. METHODS: We administered validated questionnaires (the Self-Compassion Scale-Short Form and Forms of Self-Criticism and Self-Reassurance) to evaluate pre-post changes in self-compassion and self-criticism/self-reassurance in 45 volunteers (27 women; 60%) before and after (≤24 h) an ayahuasca ceremony. Most participants (n = 29; 67.4%) had previously used ayahuasca. RESULTS: Ayahuasca resulted in significant improvements, with medium to large effect sizes (η2  = 0.184-0.276), in measures of self-compassion (p < 0.05), self-criticism (p < 0.01) and self-reassurance (p < 0.01). CONCLUSIONS: The findings of this study suggest that ayahuasca promotes well-being and self-compassion, which could have a therapeutic effect on individuals with negative affect and other psychopathological conditions. Large, controlled studies are needed to confirm these findings.

Twenty-Year Trends in the Psychopharmacological Treatment of Outpatients with Borderline Personality Disorder: A Cross-Sectional Naturalistic Study in Spain.

OBJECTIVE: Although no psychotropic drugs have been officially approved for the treatment of borderline personality disorder (BPD), medications are routinely prescribed for these patients. The primary aim of this study was to evaluate changes in the pharmacological management of patients with BPD treated in an outpatient specific unit in Spain over the past 20 years, while a secondary aim was to identify the factors associated with the prescription. METHODS: Observational and cross-sectional study of all patients with a primary diagnosis of BPD (n = 620) consecutively admitted to a BPD outpatient program in Barcelona, Spain, from 2001 through 2020. We examined trends in the prescription of antidepressants, benzodiazepines, mood stabilizers, and antipsychotics. For the analysis, prescription data were grouped into four 5-year periods (2001-2005, 2006-2010, 2011-2015, and 2016-2020). Logistic regression models were performed to identify sociodemographic and clinical variables associated with pharmacological prescription and polypharmacy. RESULTS: The percentage of patients receiving pharmacotherapy decreased over time. Antidepressant prescription rates remained high and stable over time (74% of patients), while benzodiazepine use decreased significantly during the study period (from 77 to 36%) and second-generation antipsychotic (SGA) use increased from 15 to 32%. Psychiatric comorbidity was the main factor associated with pharmacological treatment (odds ratio 2.5, 95% confidence interval 1.5-4.2) and polypharmacy, although a high percentage of patients without comorbidity were also taking medications. CONCLUSIONS: Over the past 20 years, the pharmacological treatment of BPD outpatients has undergone important changes, most notably the decrease in benzodiazepines and increase in SGAs. The findings of this study demonstrate that pharmacotherapy is much more prevalent in patients with BPD than recommended in most clinical guidelines.

Mindfulness in Borderline Personality Disorder: Decentering Mediates the Effectiveness.

BACKGROUND: Mindfulness skills training is a core component of dialectical behavior therapy (DBT) that has proven to be an effective stand-alone treatment for the general symptoms commonly present in patients with borderline personality disorder (BPD). The aim of the present study was to compare the effectiveness of mindfulness-based DBT skills training (DBT-M) to interpersonal effectiveness-based DBT skills training (DBT-IE) in reducing BPD symptoms. We also evaluated the specific mechanism of action of these therapies through two proposed mediators: decentering and emotion dysregulation. METHOD: A total of 102 participants diagnosed with BPD were included in the study. Multivariate repeated-measures ANOVAs were performed followed by a multiple mediation analysis. RESULTS: The analyses showed that DBT-M was more effective than DBT-IE in reducing BPD symptoms, although both interventions were effective in reducing emotion dysregulation. We identified a serial mediation model in which DBT-M reduced BPD symptoms by increasing decentering ability, which in turn reduced emotion dysregulation. This mediation effect showed that changes in decentering preceded improvements in emotion dysregulation. CONCLUSIONS: These findings underscore the key role of decentering as a primary mechanism of action in DBT-M, suggesting that this skill is a main component for BPD treatment.

Structural brain abnormalities in borderline personality disorder correlate with clinical severity and predict psychotherapy response.

Although previous imaging studies in borderline personality disorder (BPD) have found brain abnormalities, the results have been inconsistent. This study aimed to investigate structural brain abnormalities using voxel-based morphometry (VBM) and cortical thickness (Cth) analyses in a large sample of patients with BPD. Additionally, we aimed to determine the correlation between structural abnormalities and clinical severity and to assess its potential value at predicting psychotherapeutic response. Sixty-one individuals with BPD and 19 healthy controls underwent magnetic resonance imaging. Participants with BPD completed several self-report clinical scales, received dialectical-behavioral therapy skills training and post-therapy changes in clinical scores were also recorded. Gray matter volume (GMV) and Cth differences between groups were compared. Within the BPD group, we further characterized the structural brain correlates of clinical severity and investigated the relationship between pre-therapy structural abnormalities and therapeutic response. As potential confounders we included age, sex, educational level, and total intracranial volume (the latter only in VBM analyses). Compared to controls, the BPD group showed a reduced GMV/Cth in prefrontal areas but increased GMV in the limbic structures (amygdala and parahippocampal regions). Prefrontal abnormalities correlated with higher baseline scores on impulsivity and general BPD severity. Increased GMV in the parahippocampal area correlated with a greater emotion dysregulation. Importantly, several baseline structural abnormalities correlated with worse response to psychotherapy. Patients with BPD showed a reduced GMV in the prefrontal areas but a greater GMV in the limbic structures. Several structural abnormalities (i.e. middle and inferior prefrontal areas, anterior insula, or parahippocampal area) correlated with clinical severity and could potentially be used as imaging biological correlates biomarkers to predict psychotherapy response.

Evidence for default mode network dysfunction in borderline personality disorder.

BACKGROUND: Although executive and other cognitive deficits have been found in patients with borderline personality disorder (BPD), whether these have brain functional correlates has been little studied. This study aimed to examine patterns of task-related activation and de-activation during the performance of a working memory task in patients with the disorder. METHODS: Sixty-seven DSM-IV BPD patients and 67 healthy controls underwent fMRI during the performance of the n-back task. Linear models were used to obtain maps of within-group activations and areas of differential activation between the groups. RESULTS: On corrected whole-brain analysis, there were no activation differences between the BPD patients and the healthy controls during the main 2-back v. baseline contrast, but reduced activation was seen in the precentral cortex bilaterally and the left inferior parietal cortex in the 2-back v. 1-back contrast. The patients showed failure of de-activation affecting the medial frontal cortex and the precuneus, plus in other areas. The changes did not appear to be attributable to previous history of depression, which was present in nearly half the sample. CONCLUSIONS: In this study, there was some, though limited, evidence for lateral frontal hypoactivation in BPD during the performance of an executive task. BPD also appears to be associated with failure of de-activation in key regions of the default mode network.

Effects of mindfulness training on the default mode network in borderline personality disorder.

Patients with borderline personality disorder (BPD) present dysfunctions of the default mode network (DMN). Mindfulness training has proven effective to improve the symptoms of BPD. The present study examines the effect of mindfulness training on BPD symptomatology and DMN activity during the performance of a working memory task in patients with BPD. Sixty-five individuals with BPD were randomized to receive psychotherapy with either the mindfulness module of dialectical behavioural therapy (DBT-M) or with interpersonal effectiveness module (DBT-IE). The impact of treatments was evaluated with clinical and mindfulness variables as well as with functional magnetic resonance imaging during performance of the task. Both groups showed improvement in BPD symptoms and other clinical variables after treatment. Unexpectedly, there were no between-group differences in DMN activation or deactivation. However, activation of the left anterior insula increased in both groups after the intervention. Compared with the control group, participants in the DBT-M group presented higher deactivation in a cluster extending bilaterally from the calcarine to the cuneus and superior occipital gyri.

Acceptance and present-moment awareness in psychiatric disorders: Is mindfulness mood dependent?

The aim of the present study was to determine 1) whether deficits in two mindfulness dimensions (present-centered awareness and acceptance) were present in individuals with different psychiatric conditions and 2) whether co-existing depressive symptoms affected the mindfulness-related capacities in these groups. A total of 246 individuals, both clinical and non-clinical participants, were included in this study. The clinical sample consisted of 162 individuals; of these, 43 had a diagnosis of cocaine dependence while the remaining 119met clinical criteria for eating disorders (n = 43), major depressive disorder in remission (n = 39), and borderline personality disorder (n = 45). A non-clinical (NC) community sample consisting of 76 individuals was included as a control group. All participants completed self-report instruments to assess present-centered awareness, acceptance, and depressive symptoms. Present-centered awareness scores were significantly associated with depressive symptoms but not with the diagnostic group. By contrast, a significant effect of depressive symptoms and diagnostic group was associated with acceptance scores, with all clinical groups presenting significantly lower scores than the NC sample. These findings suggest that the association between psychopathology, mindfulness, and depressive symptoms varies depending on the specific aspect of mindfulness aspect (i.e., awareness or acceptance) evaluated.

Ayahuasca improves emotion dysregulation in a community sample and in individuals with borderline-like traits.

BACKGROUND: Research suggests that mindfulness-based interventions may improve mindfulness-related capacities (e.g., decentering, non-judging, and non-reacting) and emotion regulation. Previously, our group reported that ayahuasca could be a potential analogue of mindfulness practice. The main aim of the current study was to examine the effects of ayahuasca on emotional regulation and mindfulness-related capacities. Secondarily, we sought to explore the effects of ayahuasca on individuals with borderline personality disorder (BPD) traits. METHOD: This is an observational study of 45 volunteers who participated in an ayahuasca session. The volunteers completed various self-report instruments designed to measure emotional dysregulation (Difficulties in Emotion Regulation Scale (DERS)) and mindfulness traits (Five Facet Mindfulness Questionnaire (FFMQ)-Short Form and Experiences Questionnaire (EQ)) prior to and 24 h after the ayahuasca session. The volunteers were divided into two subgroups based on their score on the McLean Screening Instrument for BPD (MSI-BPD). Twelve participants were grouped into the BPD-like traits subgroup while the rest of them were included in the non-BPD-like subgroup. We performed within-subjects and between-group analyses. RESULTS: Overall, the participants showed significant improvements on the FFMQ subscales observing, acting with awareness, non-judging, and non-reacting and also significantly improved on decentering (EQ scale) and on the DERS subscales emotional non-acceptance, emotional interference, and lack of control. The BPD-like subgroup also showed significant improvements on the DERS subscales emotional interference and lack of control but not in mindfulness capacities. CONCLUSIONS: These findings suggest a potential therapeutic effect for ayahuasca in emotion regulation and mindfulness capacities (including decentering, acceptance, awareness, and sensitivity to meditation practice). Based on these results, we believe that ayahuasca therapy could be of value in clinical populations, such as individuals with BPD, affected by emotion dysregulation.

Factors predicting early dropout from dialectical behaviour therapy in individuals with borderline personality disorder.

BACKGROUND: Dialectical behaviour therapy skills training (DBT-ST) has proven effective to treat individuals with borderline personality disorder (BPD). However, therapy still faces the problem of early dropout. The aim of the present study is to examine which factors are associated with early dropout from DBT-ST in a sample of subjects with BPD. METHOD: 118 subjects with BPD diagnosis were included in the study. Apart from socio-demographic and clinical variables, childhood trauma history, personality dimensions, and comorbidities with other psychiatric disorders were collected. Differences in regards to the aforementioned variables were compared between individuals who dropped out prematurely from therapy and those who finalized it. RESULTS: Significant differences between groups regarding socio-demographic and clinical variables, including childhood trauma history and comorbid personality disorders, were not found. Both groups differed significantly in regards to trait impulsiveness and in comorbidity with Eating Disorders (ED) and Cocaine Use Disorder (CUD). The regression analyses showed that ED and CUD significantly predicted drop-out (p=0.011 and p=0.031 respectively), while scores in trait impulsivity showed a tendency towards signification (p=0.063). CONCLUSIONS: Comorbidities between BPD and axis I disorders (i.e., ED and CUD) should be taken into account when referring patients to DBT-ST.

Factores predictores de abandono prematuro de terapia dialéctica conductual en pacientes con trastorno límite de la personalidad / Factors predicting early dropout from dialectical behaviour therapy in individuals with borderline personality disorder

Introducción. El entrenamiento en habilidades de la terapia dialectica conductual (TDC) ha mostrado eficacia para el tratamiento de individuos con trastorno limite de la personalidad (TLP). Sin embargo, una de sus principales dificultades es el abandono prematuro de la psicoterapia. El objetivo del presente estudio es evaluar factores asociados con el abandono prematuro de una terapia grupal de entrenamiento en habilidades de la TDC en sujetos con TLP. Método. Se incluyeron 118 sujetos con TLP. Ademas de factores sociodemograficos y clinicos, se evaluan otros factores como la presencia de antecedentes traumaticos en la infancia, rasgos dimensionales de personalidad y comorbilidad con otros trastornos psiquiatricos. Se analizan las diferencias entre aquellos sujetos que finalizan la terapia con los que abandonan prematuramente. Resultados. No se observan diferencias significativas en variables sociodemograficas, de gravedad clinica, la presencia de antecedentes traumaticos en la infancia ni otros trastornos de personalidad comorbidos. Si se encuentran diferencias significativas en la subescala de impulsividad asi como en la comorbilidad con Trastorno de la Conducta Alimentaria (TCA) y Trastorno por Consumo de Cocaina (TCC). En el analisis de regresion, las variables predictoras de abandono fueron la comorbilidad con TCA (p=0,011) y con TCC (p=0,031), las puntuaciones en impulsividad mostraron una tendencia a la significacion (p=0,063). Conclusiones. La comorbilidad con trastornos del Eje I y la impulsividad son factores que se deberian tener en cuenta para valorar a priori el riesgo de abandono prematuro de terapia y optimizar el tratamiento mas idoneo para cada paciente

Relationship between effortful control and facets of mindfulness in meditators, non-meditators and individuals with borderline personality disorder.

As dimensions of effortful control (EC), activation control, attentional control, and inhibitory control could mediate the relationship between mindfulness meditation practice and the facets of mindfulness (i.e., observing, describing, acting with awareness, non-judging and non-reacting to inner experience). In this study, we tested whether participant status: meditators (n = 330), healthy non-meditators (n = 254) and individuals with borderline personality disorder (BPD) diagnosis (n = 46) predicted the facets of mindfulness and if these potential effects were mediated through the three effortful control (EC) dimensions (activation, attentional and inhibitory control). Meditators scored higher than non-meditators on attentional and inhibitory control and on the facets of mindfulness with attentional and inhibitory control partially mediating this relationship between meditation status and mindfulness facets. Participants with BPD showed lower scores on EC along with lower scores on the facets of mindfulness compared with healthy non-meditators. All three aspects of EC partially mediated the relationship between BPD and mindfulness facets. Copyright © 2018 John Wiley & Sons, Ltd.

Four Weekly Ayahuasca Sessions Lead to Increases in "Acceptance" Capacities: A Comparison Study With a Standard 8-Week Mindfulness Training Program.

Background: The therapeutic effects of the Amazonian plant tea ayahuasca may relate to its ability to enhance mindfulness capacities. Ayahuasca induces a modified state of awareness through the combined action of its active principles: the psychedelic N,N-dimethyltryptamine (DMT) and a series of centrally acting ß-carbolines, mainly harmine and tetrahydroharmine. To better understand the therapeutic potential of ayahuasca, here we compared the impact on mindfulness capacities induced by two independent interventions: (a) participation in four ayahuasca sessions without any specific purpose related to improving mindfulness capacities; and (b) participation in a standard mindfulness training course: 8 weeks mindfulness-based stress reduction (MBSR), with the specific goal of improving these skills. Methods: Participants of two independent groups completed two self-report instruments: The Five Facet Mindfulness Questionnaire (FFMQ) and the Experiences Questionnaire (EQ). The MINDSENS Composite Index was also calculated, including those EQ and FFMQ items that have proven to be the most sensitive to meditation practice. Group A (n = 10) was assessed before and after the last of four closely spaced consecutive ayahuasca sessions. Group B (n = 10) was assessed before and after completion of a standard 8-week MBSR course. Results: MBSR training led to greater increases in overall mindfulness scores after the 8-week period. MBSR but not ayahuasca led to increases in the MINDSENS Composite Index. However, the ayahuasca sessions induced comparable increases in the Non-Judging subscale of the FFMQ, specifically measuring "acceptance." Improving this capacity allows for a more detached and less judgmental stance toward potentially distressing thoughts and emotions. Results: The present findings suggest that a small number of ayahuasca sessions can be as effective at improving acceptance as more lengthy and costly interventions. Future studies should address the benefits of combining ayahuasca administration with mindfulness-based interventions. This will allow us to investigate if ayahuasca will improve the outcome of psychotherapeutic interventions.
