Aberrant Structural Connectivity of the Triple Network System in Borderline Personality Disorder Is Associated with Behavioral Dysregulation.

BACKGROUND: Core symptoms of Borderline Personality Disorder (BPD) are associated to aberrant connectivity of the triple network system (salience network [SN], default mode network [DMN], executive control network [ECN]). While functional abnormalities are widely reported, structural connectivity (SC) and anatomical changes have not yet been investigated. Here, we explored the triple network's SC, structure, and its association with BPD clinical features. METHODS: A total of 60 BPD and 26 healthy controls (HC) underwent a multidomain neuropsychological and multimodal MRI (diffusion- and T1-weighted imaging) assessment. Metrics (fractional anisotropy [FA], mean diffusivity [MD], cortical thickness) were extracted from SN, DMN, ECN (triple network), and visual network (control network) using established atlases. Multivariate general linear models were conducted to assess group differences in metrics and associations with clinical features. RESULTS: Patients showed increased MD in the anterior SN, dorsal DMN, and right ECN compared to HC. Diffusivity increases were more pronounced in patients with higher behavioral dysregulation, i.e., suicidal attempting, self-harm, and aggressiveness. No differences were detected in network structure. CONCLUSIONS: These results indicate that the triple network system is impaired in BPD at the microstructural level. The preferential involvement of anterior and right-lateralized subsystems and their clinical association suggests that these abnormalities could contribute to behavioral dysregulation.

Emotional Regulation in Teens and Improvement of Constructive Skills (EmoTIConS): study protocol for a randomized controlled trial.

BACKGROUND: Emotional dysregulation (ED) constitutes a relevant factor involved in the onset and maintenance of many mental disorders. Targeting ED during adolescence could be a determinant both to identify high-risk individuals and to promote preventive interventions. This study will aim to evaluate the impact of a brief Dialectical Behavioral Therapy (DBT)-based intervention for adolescent students by measuring changes in emotional regulation skills and impulsive behaviors. Moreover, alterations in biological features related to stress response and inflammation will be assessed as potential biological variables associated with ED. METHODS: This is a randomized trial. A total of 20 classes of adolescent students will be recruited among high schools in Brescia, a city in northern Italy. They will be randomized to the psychoeducational intervention (experimental group) or to a control condition (control group). The intervention will be based on DBT Skills Training for Emotional Problem Solving for Adolescents, and will consist of four monthly, 2-h sessions (for a total of 8 h) scheduled during regular school time. Participants will be assessed at baseline, post-intervention, and at 3 and 6 months of follow-up. The primary outcome measures will be represented by changes in the use of emotional regulation skills and by changes in the frequency of impulsive behaviors. Salivary samples will be collected at baseline and post-intervention to explore possible biological features underlying ED. DISCUSSION: Data from the present project will offer the opportunity to better understand the complex phenomenon of ED. Repeated assessment will cover several domains (emotional, behavioral, social, biological) as potential factors associated with ED. Moreover, it will be possible to establish the effect of the proposed intervention, thus helping to improve knowledge on the impact of school-based universal preventive programs. Finally, the current trial will propose an integrated screening and intervention-based model. Ultimately, this could reduce barriers to youths' mental health care by fostering collaboration between schools and mental health services. TRIAL REGISTRATION: ClinicalTrials.gov NCT04349709 .

Neurobiological and clinical effect of metacognitive interpersonal therapy vs structured clinical model: study protocol for a randomized controlled trial.

BACKGROUND: Borderline Personality Disorder (BPD) is a complex and debilitating disorder, characterized by deficits in metacognition and emotion dysregulation. The "gold standard" treatment for this disorder is psychotherapy with pharmacotherapy as an adjunctive treatment to target state symptoms. The present randomized clinical trial aims to assess the clinical and neurobiological changes following Metacognitive Interpersonal Therapy (MIT) compared with Structured Clinical Management (SCM) derived from specific recommendations in APA (American Psychiatric Association) guidelines for BPD. METHODS: The study design is a randomized parallel controlled clinical trial and will include 80 BPD outpatients, aged 18-45 enrolled at 2 recruitment centers. Primary outcome will be the clinical change in emotion regulation capacities assessed with the Difficulties in Emotion Regulation Scale (DERS). We will also investigated the effect of psychotherapy on metacognitive abilities and several clinical features such as BPD symptomatology, general psychopathology, depression, personal functioning, and trait dimensions (anger, impulsivity, alexithymia). We will evaluate changes in brain connectivity patterns and during the view of emotional pictures. A multidimensional assessment will be performed at the baseline, at 6, 12, 18 months. We will obtain structural and functional Magnetic Resonance Images (MRIs) in MIT-Treated BPD (N = 30) and SCM-treated BPD (N = 30) at baseline and after treatment, as well as in a group of 30 healthy and unrelated volunteers that will be scanned once for comparison. DISCUSSION: The present study could contribute to elucidate the neurobiological mechanisms underlying psychotherapy efficacy. The inclusion of a multidisciplinary study protocol will allow to study BPD considering different features that can affect the treatment response and their reciprocal relationships.

Effects of cognitive remediation therapy on neurocognition and negative symptoms in schizophrenia: an Italian naturalistic study.

INTRODUCTION: Cognitive remediation therapy (CRT) has been reported to positively affect neurocognitive processes among patients with schizophrenia; however, the degree to which changes in cognition is linked to improved clinical symptoms, remains poorly understood. The current study aimed to investigate whether cognitive gains were associated to improvements in negative symptoms' severity in patients with schizophrenia living in two Italian psychiatric facilities. METHODS: Patients with a diagnosis of schizophrenia were consecutively assigned to CRT (n = 33) and compared with an historical control group (n = 28). Assessments were performed at baseline and post-treatment using a neuropsychological battery (Trail Making Test A and B, Self-Ordered Pointing Task, California Verbal Learning Test), along with clinical and functioning measures. RESULTS: Visual attention (TMT-A score change) was found as the only significant predictor of improvement in negative symptoms subscale of the Positive and Negative Syndrome Scale. Furthermore, a mediation path analysis confirmed that better performance in visual attention acts as mediator of the positive association between CRT intervention and lower post-treatment negative symptoms score. CONCLUSIONS: CRT can have a positive impact on a measure of visual attention in patients with schizophrenia and on negative symptoms reduction that is mediated by this significant intervention effect.

Burnout in nonhospital psychiatric residential facilities.

OBJECTIVE: This study evaluated levels and risk factors of burnout in a sample of mental health professionals employed in nonhospital psychiatric residential facilities of northern Italy. METHODS: Nurses, nurse assistants, and educators completed a questionnaire evaluating demographic variables, burnout (Maslach Burnout Inventory), job characteristics (Job Diagnostic Survey), workload, relationships with colleagues, and support from supervising coordinators. A total of 202 (83% response rate) questionnaires were analyzed. Logistic linear regressions were used to estimate predictors of burnout dimensions. RESULTS: Burnout risk was widespread. Low feedback about job performance, poor support from coordinators, and young age predicted emotional exhaustion. Low feedback about job performance predicted feelings of depersonalization. Low task identity and young age predicted reduced feelings of personal accomplishment. CONCLUSIONS: Interventions to prevent burnout among employees should be developed. These include providing feedback about performance, clearly identifying the tasks of the job, and providing support.

Personality traits in an italian sample: relationship with anxiety and depression.

Personality traits provide a description of individual emotional and cognitive processes that modulate thoughts, feelings and behaviour. Few studies have investigated the relationship of personality traits with depression and anxiety in the general Italian population. The aim of the present study was to replicate previous evidences about the association of personality traits with anxiety and depression in a general Italian population sample.We recruited 418 volunteers through different sources; such as university, newspaper advertisement, hospital, and elderly association. 327 subjects accepted to participate to the study and were screened with the Mini-International Neuropsychiatric Interview (M.I.N.I.) in order to assess DSM-IV Axis I disorders and with the Temperament and Character Inventory (TCI) in order to measure personality traits.Based on the assessment made by the MINI, the whole sample consisted of 266 (81%) subjects without and 61 subjects (19%) with life-time DSM-IV Axis I disorders. Volunteers with life-time anxiety and depressive disorders showed high scores in Harm Avoidance as well as low scores in Self-Directedness and in the Novelty Seeking subscale "Exploratory Excitability".Our results support previous evidences showing that personality traits, in particular Harm Avoidance and Self-Directedness, could represent markers of vulnerability for depression and anxiety disorders.
