Please Don't Leave Me-Separation Anxiety and Related Traits in Borderline Personality Disorder

Anxious-depressive attack and rejection sensitivity-Toward a new approach to treatment-resistant depression

This paper aimed to find clues to treatment-resistant depression (TRD) solutions. Depression comorbid with anxiety is often treatment-resistant where anxious-depressive attack (ADA) often lurks. ADA is a recently proposed clinical idea for just a psychological version of a panic attack. It mostly begins with an abrupt surge of intense anxiety followed by uninterrupted intrusive thoughts; lasting ruminations about regret or worry produced by violent anxiety, agitation, and loneliness. Acting-out behaviors such as deliberate self-injury and over-dose may also be observed during the attack. As the basic psychopathology of ADA, rejection sensitivity (RS) was revealed by a structural equation model. It is said that the presence of RS in depressive disorders implies a poor prognosis. The following biological markers for RS were reviewed in the literature: first, the involvement of the μ-opioid receptor function in RS and, secondly, hypersensitivity of the dopamine D4 receptor (DRD4) in the medial prefrontal cortex. The latter has been suggested in fear-conditioned animal experiments. Manipulation of the μ-opioid receptor function together with the DRD4 function may culminate in a treatment for RS, which could contribute to the development of a treatment for TRD via the improvement of ADA.

Level of Structural Integration and Its Association with Intersession Experiences and Outcomes: A Pilot Study

The level of structural integration (LSI), a psychodynamic/psychoanalytic concept originally developed by the Operationalized Psychodynamic Diagnosis (OPD), provides a promising empirical approach that is recognized beyond the boundaries of psychoanalysis and is highly relevant for therapy and research. The aim of our study was to investigate the intersession experiences of patients in psychotherapy with different levels of structural integration. The sample consisted of 69 inpatients who were undergoing psychotherapeutic treatment. The patients were asked to complete the German version of the Intersession Experience Questionnaire (IEQ), the short version of the OPD Structure Questionnaire (OPD-SQS) and the Brief-Symptom Inventory (BSI). LSI is associated with the situations, contents and negative emotions in the intersession experiences of patients, as well as their symptom distress over the course of therapy. Furthermore, the level of structural integration is a significant predictor of outcomes. Patients with different LSI had different intersession experiences.

Relationship of behavioral inhibition to separation anxiety in a sample (N = 377) of adult individuals with mood and anxiety disorders

BACKGROUND

Behavioral Inhibition (BI) is an early temperamental trait characterized by shyness, withdrawal, avoidance, uneasiness, and fear of unfamiliar situations, people, objects, and events. The DSM-5 refers to behavioral inhibition as a temperamental factor related to neurodevelopmental conditions in childhood, including attention deficit hyperactivity disorder, selective mutism, and specific phobias; and to its influence on adult anxiety disorders including social anxiety disorder, agoraphobia, and generalized anxiety disorder, but, interestingly, not separation anxiety disorder (SAD). However, there are phenomenological overlaps between BI and SAD. We aimed to explore whether there is a correlation between BI as an early temperamental trait and childhood or adult separation anxiety disorder.

METHODS

The study was conducted in 377 consecutive adults (mean age 40.2±12.4 years) outpatients with anxiety and mood disorders as the principal diagnosis, grouped on the presence/absence of a DSM-5 diagnosis of childhood or adult separation anxiety disorder. Separation anxiety was assessed by the Structured Clinical Interview for Separation Anxiety (SCI-SAS) and the Adult Separation Anxiety Checklist (ASA27). Behavioral inhibition was assessed by the Retrospective Self-Report of Inhibition (RSRI).

RESULTS

The four comparison groups included: 1) 168 patients without childhood or adult SAD, 2) 81 with adult SAD, 3) 97 with both adult SAD and childhood SAD, and 4) 31 with childhood SAD only. The group with both adult and childhood SAD had the highest scores on RSRI total and sub-scale scores. Both groups with adult SAD had significantly higher RSRI scores than the group with only childhood SAD or without SAD. Significant bivariate correlations were found between ASA-27 scores and RSRI scores. Correlations between RSRI scores and measures of anxiety and depressive symptoms were significantly weaker than those on the ASA-27. Regression analyses showed a significant predictive value of RSRI scores on ASA-27 total score, but not of age of onset of SAD.

CONCLUSIONS

BI has an onset in the very first years of life and may represent a potential developmental endophenotype for later anxiety disorders. Our findings indicate that BI and separation anxiety are connected in individuals with affective and anxiety disorders. This may have important clinical and therapeutic implications for preventive interventions.

Frontal EEG asymmetry moderates the relation between borderline personality disorder features and feelings of social rejection in adolescents

Although associations among borderline personality disorder (BPD), social rejection, and frontal EEG alpha asymmetry scores (FAA, a neural correlate of emotion regulation and approach-withdrawal motivations) have been explored in different studies, relatively little work has examined these relations during adolescence in the same study. We examined whether FAA moderated the relation between BPD features and rejection sensitivity following a validated social exclusion paradigm, Cyberball. A mixed, clinical-community sample of 64 adolescents (females = 62.5%; Mage = 14.45 years; SD = 1.6; range = 11-17 years) completed psychodiagnostic interviews and a self-report measure of BPD (Time 1). Approximately two weeks later (Time 2), participants completed a resting EEG recording followed by Cyberball. FAA moderated the relation between BPD features and overall feelings of rejection following Cyberball: individuals with greater relative left FAA had the highest and lowest feelings of social rejection depending on whether they had high and low BPD feature scores, respectively. Results remained after controlling for age, sex, gender, depression, and BPD diagnosis. These results suggest that FAA may moderate the relation between BPD features and social rejection, and that left frontal brain activity at rest may be differentially associated with those feelings in BPD. Findings are discussed in terms of the link between left frontal brain activity in the regulation and dysregulation of social approach behaviors, characteristic of BPD.

Differences in severity of eating disorder symptoms between adults with depression and adults with anxiety

OBJECTIVES

Anxiety and depression are both considered maintaining factors for eating disorders (ED) but it is still unclear if one is more strongly associated with ED symptoms than the other. We examined differences in severity of ED symptoms among adults with either, both, or neither depression and anxiety.

METHODS

Volunteers (N = 3,780) to the project implicit mental health website ( https://implicit.harvard.edu/ ) self-reported their ED status (current ED: n = 374, past ED: n = 436; no ED: n = 2,970), their current depression/anxiety status, and their ED symptoms (using the Eating Attitudes Test). ANOVAs with post hoc comparisons were used to examine relationships between ED symptoms and comorbid depression/anxiety status among currently ill, recovered, and never ill individuals.

RESULTS

Participants without comorbidities had the least and participants with both comorbidities had the most severe ED symptoms (p = .021). Participants with anxiety alone had more severe ED symptoms relative to those with depression alone across groups (current ED: p = .024; past ED: p = .019; no EDs: p = .021).

DISCUSSION

These findings demonstrate, in contrast with an earlier study among youth with EDs (Hughes et al., 2013), that comorbid anxiety may be linked with more severe ED symptoms relative to comorbid depression. It is possible that anxiety serves as a maintaining factor for ED symptoms such that dieting and other ED-related behaviors may function to modulate symptoms of anxiety.

Treatment Refractory Internalizing Behaviour Across Disorders: An Aetiological Model for Severe Emotion Dysregulation in Adolescence

Auto-aggressive behaviour, especially treatment refractory suicidality in adolescents with psychiatric disorders, may be challenging to clinicians. In search of therapeutic possibilities, we have integrated current opinions regarding causality and interdependency of suicidality and auto-aggressive behaviour across disorders within the HiTOP framework. We propose a developmental model regarding these unsettling behaviours in youths that may help to guide future directions for research and interventions. We argue that the interdependent development of biologic factors, attachment, moral reasoning and emotion regulation in an overprotective environment may lead to social anxiety and later during development to emotion dysregulation and severe internalizing behaviour disorders. To optimize treatment efficacy for both internalizing and externalizing behaviour, we emphasize the importance transdiagnostic interventions, such as addressing non-compliance, restoration of trust between parents and their child, and limitation of avoidance behaviour. These may be seen as higher order interventions within the HiTOP framework.

[Separation anxiety disorder]

In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) separation anxiety disorder has been included in the chapter on anxiety disorders, thereby removing the age of onset restriction that previously required first onset during childhood or adolescence. Separation anxiety disorder has a lifetime prevalence of 4.8% and onset often occurs after the age of 18 years. Despite the high prevalence, separation anxiety disorder is often underdiagnosed and subsequently remains untreated. This narrative review summarizes the etiology, clinical features, diagnostic criteria as well as important differential diagnostic aspects, common comorbidity profiles and treatment implications of separation anxiety disorder. Furthermore, relevant implications for everyday practice and future perspectives for treatment and research are discussed.

Genetic and Environmental Causes of Individual Differences in Borderline Personality Disorder Features and Loneliness are Partially Shared

Loneliness is related to mental and somatic health outcomes, including borderline personality disorder. Here, we analyze the sources of variation that are responsible for the relationship between borderline personality features (including four dimensions, affective instability, identity disturbance, negative relationships, self-harm and a total score) and loneliness. Using genetically informative data from two large nonclinical samples of adult twin pairs from Australia and the Netherlands (N = 11,329), we estimate the phenotypic, genetic and environmental correlations between self-reported borderline personality features and loneliness. Individual differences in borderline personality and loneliness were best explained by additive genetic factors with heritability estimates h2 = 41% for the borderline personality total score and h2 = 36% for loneliness, with the remaining variation explained by environmental influences that were not shared by twins from the same pair. Genetic and environmental factors influencing borderline personality (total score and four subscales separately) were also partial causes of loneliness. The correlation between loneliness and the borderline personality total score was rph = .51. The genetic correlation was estimated at rg = .64 and the environmental correlation at re = .40. Our study suggests common etiological factors in loneliness and borderline personality features.

A neurobiological framework of separation anxiety and related phenotypes

In the DSM-5, separation anxiety disorder (SAD) is newly classified in the chapter on anxiety, renewing research efforts into its etiology. In this narrative review, we summarize the current literature on the genetic, endocrine, physiological, neural and neuropsychological underpinnings of SAD per se, SAD in the context of panic disorder, separation anxiety symptoms, and related intermediate phenotypes. SAD aggregates in families and has a heritability of ~43%. Variants in the oxytocin receptor, serotonin transporter, opioid receptor µ1, dopamine D4 receptor and translocator protein genes have all been associated with SAD. Dysregulation of the hypothalamus-pituitary-adrenal axis, dysfunctional cortico-limbic interaction and biased cognitive processing seem to constitute further neurobiological markers of separation anxiety. Hypersensitivity to carbon dioxide appears to be an endophenotype shared by SAD, panic disorder and anxiety sensitivity. The identification of biological risk markers and its multi-level integration hold great promise regarding the prediction of SAD risk, maintenance and course, and in the future may allow for the selection of indicated preventive and innovative, personalized therapeutic interventions.
