The separation of adult separation anxiety disorder

The definition of treatment resistance in anxiety disorders: a Delphi method-based consensus guideline

Anxiety disorders are very prevalent and often persistent mental disorders, with a considerable rate of treatment resistance which requires regulatory clinical trials of innovative therapeutic interventions. However, an explicit definition of treatment-resistant anxiety disorders (TR-AD) informing such trials is currently lacking. We used a Delphi method-based consensus approach to provide internationally agreed, consistent and clinically useful operational criteria for TR-AD in adults. Following a summary of the current state of knowledge based on international guidelines and an available systematic review, a survey of free-text responses to a 29-item questionnaire on relevant aspects of TR-AD, and an online consensus meeting, a panel of 36 multidisciplinary international experts and stakeholders voted anonymously on written statements in three survey rounds. Consensus was defined as ≥75% of the panel agreeing with a statement. The panel agreed on a set of 14 recommendations for the definition of TR-AD, providing detailed operational criteria for resistance to pharmacological and/or psychotherapeutic treatment, as well as a potential staging model. The panel also evaluated further aspects regarding epidemiological subgroups, comorbidities and biographical factors, the terminology of TR-AD vs. "difficult-to-treat" anxiety disorders, preferences and attitudes of persons with these disorders, and future research directions. This Delphi method-based consensus on operational criteria for TR-AD is expected to serve as a systematic, consistent and practical clinical guideline to aid in designing future mechanistic studies and facilitate clinical trials for regulatory purposes. This effort could ultimately lead to the development of more effective evidence-based stepped-care treatment algorithms for patients with anxiety disorders.

Adult Separation Anxiety and Childhood Traumas: The Mediating Role of Cognitive Distortions

While there are many studies on the relationship between anxiety disorders and childhood traumas in the literature, there are limited studies on the relationship between separation anxiety disorders and traumatic experiences in early life. It is widely known that trauma and negative cognitive processes are important factors in the etiology and prognosis of psychiatric disorders. In this study, it was aimed to determine the relationship between adult separation anxiety levels and childhood traumas and cognitive distortions, and to examine the mediating role of cognitive distortions in the relationship between childhood traumas and separation anxiety. A total of 366 students attending a private university were included in the study. The scales, which were converted into online questionnaires by the researchers, were sent to the students via e-mail, and were administered online. The participants were evaluated using "Adult Separation Anxiety Questionnaire", "Childhood Trauma Questionnaire", and "Cognitive Distortions Scale". The results of the study indicated that there was a positive and significant relationship between adult separation anxiety levels and childhood sexual abuse while there was no statistically significant correlation between adult separation anxiety levels and physical and emotional abuse, or physical and emotional neglect. A positive and significant relationship was found between separation anxiety levels and the sub-dimensions of cognitive distortions' self-image, self-blame, helplessness, hopelessness, and preoccupation with danger. In addition, it was determined that the helplessness and preoccupation with danger sub-dimensions of cognitive distortions had a full mediator effect on the relationship between sexual abuse and separation anxiety. Our results show that there is a positive relationship between separation anxiety disorder and childhood sexual abuse, and cognitive distortions play a mediating role between both variables.

The relationship between anxiety and internet gaming disorder in children during COVID-19 lockdown: a network analysis

Background

Internet gaming disorder (IGD) has become a social problem in children. Evidence from previous studies has proven that anxiety is associated with IGD. However, IGD was always assessed as a whole based on total scores, and the fine-grained relationship between anxiety and IGD was hidden.

Objective

The present study aims to investigate the fine-grained relationship between anxiety and IGD in elementary school students during the COVID-19 lockdown, and to identify potential targets for psychological interventions.

Methods

During the lockdown caused by the COVID-19 pandemic, 667 children from a primary school in China were investigated by the Spence Children's Anxiety Scale-Short Version and Internet Gaming Disorder Scale. R4.1.1 software was used to construct a network model, assess bridge centrality, and test the robustness of the network and conduct a network.

Results

There were 23 cross-community edges (weight ranged from -0.03 to 0.12), and each node of anxiety was connected to different nodes of IGD. The nodes with the top 80th percentile bridge expected influence were A2 "social phobia" (0.20), A3 "panic disorder" (0.21) and IGD5 "escape" (0.22). The robustness of the network was acceptable.

Conclusion

From the perspective of network analysis, the present study explored the correlation pathways between anxiety and IGD in children and identified social phobia and panic disorder as the best targets for intervention to reduce IGD.

To Leave is to Die a Little: Assessing the Symptom Structure of Separation Anxiety Disorder in Left-Behind Emerging Adults

The literature on separation anxiety disorder (SAD) presented two contentious issues relating to its assessment. First, studies are scarce in assessing the symptom structure of DSM-5 SAD among the adult population. Second, the accuracy in assessing the severity of SAD through measuring the intensity of disturbance and the frequency of occurrence of symptoms is yet to be studied. To address these limitations, the present study aimed to: (1) examine the latent factor structure of the newly developed separation anxiety disorder symptom severity inventory (SADSSI); (2) evaluate the necessity of using frequency or intensity formats through comparison of differences in the latent level; and (3) investigate SAD latent class analysis. Utilizing 425 left-behind emerging adults (LBA), the findings showed that a general factor with two dimensions (i.e., response formats) measuring frequency and intensity symptom severity separately has excellent fit and good reliability. Finally, the latent class analysis yielded a three-class solution best fitting to the data. Overall, the data provided evidence for the psychometric soundness of SADSSI as an assessment tool for separation anxiety symptoms among LBA.

The unseen aspect of negative birth experience: Blues of birth

The purpose of the authors in this paper is to investigate the effects of negative experiences during delivery and postpartum period on the relationship between the mother. The quantitative part of this study was conducted with 289 mothers and the qualitative part with 40 mothers. It was found that experiencing upsetting problems during delivery (p = 0.006) and in the postpartum period (p = 0.002) had an effect on separation anxiety. Based on the examination of the feelings experienced during annoying or distressing situations in the postpartum period, it was determined that there was a significant correlation between guilt (p = 0.000), fear of not being a good mother (p = 0.035), and feeling weak (p = 0.001) and separation anxiety. Blues of birth is fear and anxiety that the baby will be harmed if the mother is separated from it, and it is attributed to negative experiences during delivery and the postpartum period.

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.

The cognitive anxiety sensitivity treatment (CAST) in anxiety prevention - Focus on separation anxiety and interoception

Given the high prevalence and considerable clinical and societal burden of anxiety disorders, preventive measures are urgently warranted to reduce their incidence and overall healthcare impact. Anxiety sensitivity (AS) - a key element in learning theories of anxiety disorders in the context of interoceptive conditioning - constitutes a malleable risk factor of particularly panic disorder and separation anxiety, which share developmental, nosological, epidemiological and pathomechanistic characteristics. The computer-assisted 'Cognitive Anxiety Sensitivity Treatment' (CAST) targeting interoceptive anxiety symptoms (cf. Schmidt et al., 2014) was translated, intensified and culturally adapted to German and evaluated in a sample of 105 healthy adult volunteers with elevated AS (mean ASI-3: 29.5) applying a randomized design. Success of the intervention was measured as a function of AS and separation anxiety (ASA-27) ∼6 weeks (T1) and ∼6 months (T2) after the intervention. As compared to waitlist, CAST resulted in a significant reduction of AS at both T1 and T2. Separation anxiety was not directly reduced by the intervention, but decreased mediated by a decline in AS. A composite interoceptive score capturing changes in sensitivity to respiratory symptoms during the baseline therapist-accompanied CAST session was shown to be predictive of overall response at T1. In sum, CAST-German Version was successfully established as an effective intervention reducing AS, while at the same time indirectly decreasing separation anxiety. A composite interoceptive score predicting treatment response might aid in further delineating risk markers informing targeted preventive interventions for anxiety disorders.

[Clinical variants and types of course of separation anxiety disorder in adults]

OBJECTIVE

To study clinical manifestations of separation anxiety disorder (SAD) in adults with nonpsychotic mental disorders.

MATERIAL AND METHODS

Fifty outpatients over 18 years of age with SAD and comorbid non-psychotic mental disorders were assessed for diagnosis by MINI and the Structured Clinical Interview for Separation Anxiety Symptoms (SCI-SAS), the Adult Separation Anxiety Self-Report Checklist (ASA-27), HARS, the Experiences in Close Relationship Scale (ECR), the Personality Inventory for DSM-5 (PID-5), the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q).

RESULTS AND CONCLUSION

Two clinical variants of the disorder: affective and cognitive-behavioral as well as two variants of the course: with onset in childhood and in adults are identified. Clinical variants and types differ in the spectrum of comorbidity, objects and styles of attachment, personality characteristics as well as correlations and prognosis.

Separation anxiety disorder among outpatients with major depressive disorder: Prevalence and clinical correlates

Prior studies have reported that separation anxiety disorder (SEPAD) can continue into or may begin in adulthood. Association of SEPAD with other psychiatric disorders has been frequently examined, and high rates of comorbidities have been found. The aim of this study was to investigate the prevalence and clinical correlation of SEPAD in adult patients undergoing treatment for major depressive disorder (MDD). The study sample was comprised of 100 outpatients. Participants underwent a DSM-5-based comprehensive assessment. Purposefully-designed semi-structured sociodemographic information and illness history forms were filled out by the researchers, and diagnoses of SEPAD were made using the Structured Clinical Interview for Separation Anxiety Symptoms, Separation Anxiety Symptom Inventory and Adult Separation Anxiety Survey. The frequency of SEPAD was 41% in patients with MDD, three-quarters of whom were adult onset. The use of new-generation antidepressants, adjunctive medications and comorbidity of other anxiety disorders were higher in patients with SEPAD (p < 0.05). SEPAD was highly prevalent, with a majority of cases starting in adulthood among patients with MDD, while SEPAD comorbidity was associated with high levels of anxiety and an increased likelihood of suboptimal response to usual depression treatment. Further studies are required to define the relevance and pathological basis for the comorbidity of SEPAD in people with MDD.

[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.

Angststörungen – von der ICD-10 zur ICD-11

Zusammenfassung. Hintergrund: Nach 12 Jahren Entwicklung wird die 11. Version der International Classification of Diseases (ICD-11) von der Weltgesundheitsorganisation (WHO) im Januar 2022 in Kraft treten. Methodik: Im Rahmen eines selektiven Übersichtsartikels werden die Veränderungen im Hinblick auf die Klassifikation von Angststörungen von der ICD-10 zur ICD-11 zusammenfassend dargestellt. Ergebnis: Die diagnostischen Kriterien der generalisierten Angststörung, Agoraphobie und spezifischen Phobien werden angepasst. Die ICD-11 wird auf Basis einer Lebenszeitachse neu organisiert, sodass die kindesaltersspezifischen Kategorien der ICD-10 aufgelöst werden. Die Trennungsangststörung und der selektive Mutismus werden damit den „regulären“ Angststörungen zugeordnet und können zukünftig auch im Erwachsenenalter diagnostiziert werden. Neu ist ebenso, dass verschiedene Symptomdimensionen der Angst ohne kategoriale Diagnose verschlüsselt werden können. Diskussion: Die Veränderungen im Bereich der Angsterkrankungen umfassen verschiedene Aspekte und sind in der Gesamtschau nicht unerheblich. Positiv zu bewerten ist die Einführung einer Lebenszeitachse und Parallelisierung mit dem Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Schlussfolgerungen: Die entwicklungsbezogene Neuorganisation in der ICD-11 wird auch eine verstärkte längsschnittliche Betrachtung von Angststörungen in der Klinik sowie Forschung zur Folge haben. Damit rückt insbesondere die Präventionsforschung weiter in den Fokus.

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.

The ALPIM (Anxiety, Laxity, Pain, Immune, and Mood) Syndrome in Adolescents and Young Adults: A Cohort Study

OBJECTIVE

ALPIM (anxiety, laxity, pain, immune, and mood) syndrome has been previously described in adults. The authors aimed to identify its occurrence in adolescents and confirm its existence in adults. Given the association of the disorder with somatic symptoms, separation anxiety disorder (SAD) was explored as an ALPIM comorbidity.

METHODS

Medical records of patients aged 11-34 with a diagnosis of depression or anxiety (panic disorder, SAD, social anxiety or generalized anxiety disorder) seen during a 1-year period were reviewed. Data were collected on the presence of ALPIM comorbidities. Analyses were conducted to detect their co-occurrence and evaluate possible predictors of the ALPIM syndrome.

RESULTS

Inclusion criteria were met by 185 patient charts. A significant association was observed between the ALPIM comorbidities with 20 study subjects (10.8%) meeting criteria for ALPIM syndrome (patients with one or more diagnoses from each ALPIM domain). Patients with SAD had increased odds of being diagnosed with ALPIM (odds ratio=7.14, 95% CI=2.48-20.54, p<0.001). Neither major depression nor generalized anxiety disorder was found to be predictive of ALPIM syndrome. There was no difference in the prevalence of ALPIM-related comorbidities between study subjects <18 years old compared with those ≥18 years old.

CONCLUSIONS

These findings reestablish the association of distinct psychiatric and nonpsychiatric conditions described as the ALPIM syndrome. Furthermore, the syndrome may present during adolescence. SAD may be an independent predictive factor for the occurrence of ALPIM syndrome. Patients with individual ALPIM comorbidities should be assessed for the syndrome, especially if they have a history of SAD.

The Diagnosis and Treatment of Anxiety Disorders

BACKGROUND

Anxiety disorders are the most common type of mental illness in Europe, with a 12-month prevalence of 14% among persons aged 14 to 65. Their onset is usually in adolescence or early adulthood. The affected patients often develop further mental or somatic illnesses (sequential comorbidity).

METHODS

This review is based on pertinent publications retrieved by a selective search in PubMed.

RESULTS

The group of anxiety disorders includes generalized anxiety disorder (GAD), phobic disorders, panic disorders, and two disorders that are often restricted to childhood-separation anxiety and selective mutism. A comprehensive differential diag- nostic evaluation is essential, because anxiety can be a principal manifestation of other types of mental or somatic illness as well. Psychotherapy and treatment with psychoactive drugs are the therapeutic strategies of first choice. Of all types of psycho- therapy, cognitive behavioral therapy has the best documented efficacy. Modern antidepressants are the drugs of first choice for the treatment of panic disorders, agoraphobia, social phobia, and GAS; pregabalin is a further drug of first choice for GAS.

CONCLUSION

In general, anxiety disorders can now be effectively treated. Patients should be informed of the therapeutic options and should be involved in treatment planning. Current research efforts are centered on individualized and therefore, it is hoped, even more effective treatment approaches than are available at present.

Diagnosis and Management of Anxiety Disorders

PURPOSE OF REVIEW

This article provides a synopsis of the current understanding of the pathophysiology of anxiety disorders, the biological and environmental risk factors that contribute to their development and maintenance, a review of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnostic criteria, and a practical approach to the treatment of anxiety disorders in adults.

RECENT FINDINGS

Despite the ubiquity of anxiety, the evidence is that most individuals with an anxiety disorder are not identified and do not receive guideline-level care. In part, this may be because of the manifold clinical presentations of anxiety disorders and clinicians' lack of confidence in accurately diagnosing and treating these conditions, especially in nonpsychiatric settings. Anxiety disorders represent the complex interplay between biological, psychological, temperamental, and environmental factors. Converging lines of evidence point to dysfunction in regulating activity in the "threat circuit" in the brain as a putative common pathophysiology underlying anxiety disorders. Evidence-based treatments for anxiety disorders, such as cognitive-behavioral therapy and antidepressant medications, have been shown to regulate activity in this circuit, which consists of reciprocal connections between the dorsomedial prefrontal cortex, insula, and amygdala.

SUMMARY

Anxiety disorders are the most common class of emotional disorders and a leading cause of disability worldwide. A variety of effective treatment strategies are available, which may exert their therapeutic benefits from top-down or bottom-up modulation of the dysfunctional brain activity associated with anxiety disorders.

The role of beta-adrenolytic drugs in treating anxiety disorders

Introduction: Beta blockers are mainly used in treating cardiovascular diseases. However, it has been observed that these drugs have also an anxiolytic potential. Over the years, a number of clinical trials have been conducted aimed at determining the effectiveness of beta blockers in treating anxiety disorders.

The aim of the article: The main objective of the article is to present the significance and position of adrenolytic drugs in the pharmacotherapy of anxiety disorders on the basis of available literature. Moreover, the authors also decided to take into account the data from current research results, considering the problem of side effects of using adrenolytic drugs - especially the controversial reports on their effect on the development of affective disorders.

Method: An analysis was conducted of articles from Medline/PubMed database, selected on the basis of the following key words: anxiety disorders, beta blockers, adrenolytic drugs, as well as on the basis of their dates of publication: 1960-2017. In order to conduct a reliable and complete review of literature, the authors decided to include works from quite an extended period of time. The articles included in the review were published in Polish and English.

Results: The review of articles concerning the treatment of anxiety disorders clearly suggests that propranolol is effective in reducing the frequency of panic attacks and the tendency for avoidance behavior in patients with agoraphobia. Other studies report on potential benefits in terms of early interventional prevention and treating posttraumatic stress disorder with propranolol. However, there is lack of randomized clinical trials concerning the therapeutic effect of other adrenolytic drugs in treating anxiety disorders. Early research works reported that (mainly lipophilic) beta blockers may have a depressogenic effect; however, the latest studies have not confirmed it.

The contemporary research on the therapeutic potential of beta blockers in treating anxiety disorders is insufficient. What seems to be most promising, however, are reports concerning the desirable effects of using adrenolytic drugs in treating posttraumatic stress disorder, which implicates the necessity of conducting further research verifying the validity of their application.

[Separation anxiety disorder in adults - a new diagnostic category]

Anxiety separation disorder (SAD) became the subject of increased attention of researchers in recent decades. DSM-5 and project of ICD-11 allow us to treat this disorder as an independent nosological unit without attachment to age. The review provides information on the prevalence, clinical manifestations and diagnosis of SAD in adults, summarizes information on the etiopathogenesis, relations to other psychiatric disorders, and highlights the lack of modern therapeutic approaches to SAD. The purpose of this review is to raise the level of knowledge about SAD and its new positioning in classification systems.

Oxytocin receptor gene variation, behavioural inhibition, and adult separation anxiety: Role in complicated grief

OBJECTIVES

Complicated grief (CG) following bereavement significantly increases the risk for mood and anxiety disorders. The severity of grief reactions may be interactively influenced by temperamental and psychological factors such as behavioural inhibition (BI) and separation anxiety (SA) as well as biological factors. Given its central role in attachment and stress processing, a genetic variant in the oxytocin receptor (OXTR) gene was thus investigated in order to elucidate the direction of association as well as its interaction with BI and SA in the moderation of CG severity.

METHODS

Ninety-three patients with mood and anxiety disorders were evaluated for CG by means of the Inventory of Complicated Grief (ICG), for BI using the Retrospective Self-Report of Inhibition (RSRI), and for symptoms of SA during adulthood using the Adult Separation Anxiety Scale (ASA-27). All patients were genotyped for OXTR rs2254298.

RESULTS

OXTR genotype interacted with BI and, on a trend-level, with adult SA, to increase CG. Specifically, higher levels on the RSRI and ASA-27 scales, respectively, were related to higher ICG scores in GG genotype carriers.

CONCLUSIONS

The present study for the first time suggests a gene-environment interaction effect of an OXTR gene variant with BI and possibly also symptoms of adult SA in the moderation of vulnerability for CG.

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

PURPOSE OF REVIEW

In light of the apparent symptomatic resemblance of separation anxiety disorder (SAD) symptoms on the one hand and abandonment fears, anxiousness, and separation insecurity central to borderline personality disorder (BPD) on the other hand, a comprehensive overview of separation anxiety and related traits in BPD is provided.

RECENT FINDINGS

Epidemiological, environmental, psychological, and neurobiological data connecting BPD to separation events, feelings of loneliness, insecure attachment styles, dimensional separation anxiety as well as SAD per se suggest a partly shared etiological pathway model underlying BPD and SAD. Differential diagnostic aspects and implications for treatment are discussed, highlighting separation anxiety as a promising transdiagnostic target for specific psychotherapeutic and pharmacological treatment approaches in BPD. This innovative angle on cross-disorder symptomatology might carry potential for novel preventive and therapeutic avenues in clinical practice by guiding the development of interventions specifically targeting separation anxiety and attachment-related issues in BPD.

Treatment of anxiety disorders

Anxiety disorders (generalized anxiety disorder, panic disorder/agoraphobia, social anxiety disorder, and others) are the most prevalent psychiatric disorders, and are associated with a high burden of illness. Anxiety disorders are often underrecognized and undertreated in primary care. Treatment is indicated when a patient shows marked distress or suffers from complications resulting from the disorder. The treatment recommendations given in this article are based on guidelines, meta-analyses, and systematic reviews of randomized controlled studies. Anxiety disorders should be treated with psychological therapy, pharmacotherapy, or a combination of both. Cognitive behavioral therapy can be regarded as the psychotherapy with the highest level of evidence. First-line drugs are the selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors. Benzodiazepines are not recommended for routine use. Other treatment options include pregabalin, tricyclic antidepressants, buspirone, moclobemide, and others. After remission, medications should be continued for 6 to 12 months. When developing a treatment plan, efficacy, adverse effects, interactions, costs, and the preference of the patient should be considered.

A randomized controlled pilot trial of vilazodone for adult separation anxiety disorder

BACKGROUND

Separation anxiety disorder was recently recognized by fifth edition of the Diagnostic and Statistical Manual of Mental Disorders as a diagnosis in adults, but no publications to date have characterized a sample of patients seeking treatment for adult separation anxiety disorder (ASAD) or assessed treatment efficacy. We hypothesized that vilazodone, a selective serotonin reuptake inhibitor (SSRI) and serotonin 1a (5HT1_a ) receptor partial agonist, would have efficacy in ASAD, because SSRIs have appeared efficacious in children with mixed diagnoses including separation anxiety disorder and in animal models of separation anxiety.

METHODS

In this pilot study, 24 adults (ages 18-60) with a principal diagnosis of ASAD were randomized to 12 weeks of double-blind treatment with vilazodone (n = 13) or placebo (n = 11). Outcome was assessed by an independent evaluator and self-ratings, and analyzed with mixed effect models.

RESULTS

This sample was predominantly female (67%), with comorbid psychiatric disorders (58%), and adult onset of separation anxiety disorder (62%). Response rates at week 12 did not differ significantly between groups. Across all time points, the vilazodone group evidenced greater improvement on the Structured Clinical Interview for Separation Anxiety Symptoms (P = .026) and the Quality of Life Enjoyment and Satisfaction Questionnaire (P = .011), and trends toward greater improvement on the Adult Separation Anxiety Questionnaire (P = .054) and the Clinical Global Impression-Change Scale (P = .086), all with large between-group effect sizes.

CONCLUSIONS

Findings demonstrate feasibility of a clinical trial in ASAD, and they suggest that vilazodone may have efficacy in the treatment of ASAD and warrants further study.
