Treatment utilization and treatment barriers in individuals with body dysmorphic disorder

Is cognitive behavioral therapy an efficacious treatment for psychological interventions in body dysmorphic disorders? A meta-analysis based on current evidence from randomized controlled trials

BACKGROUND

Clinical guidelines and some studies recommend cognitive-behavioral therapy (CBT) as the most effective treatment for body dysmorphic disorder (BDD). However, owing to the lack of randomized controlled trials (RCTs), the research evidence is insufficient. This study aimed to explore the effectiveness of CBT in the treatment of BDD using RCTs. This meta-analysis was registered in PROSPERO (CRD42023410577).

METHODS

After a literature search and screening, 11 RCTs with 667 patients were included. The ROB 2.0 tool, funnel plots, sensitivity analysis, and meta-regression analysis were used to assess the quality, publication bias, and sources of heterogeneity.

RESULTS

After CBT intervention, the severity of BDD (SMD = -1.73, 95 % CI (confidence interval) = [-2.90; -0.57]), depression symptoms (SMD = -1.72, 95 % CI = [-3.16; -0.28]), and anxiety levels were all reduced in the patients of the experimental group; the remission of BDD (OR = 7.37, 95 % CI = [2.17; 24.98]) and the response of BDD (OR = 8.86, 95 % CI = [4.85; 16.18]) were all increased; incorrect beliefs such as disability and BABS were also reduced; the quality of life was improved. The difference between the groups was statistically significant (p < 0.01). Meta-regression analysis showed that age and sample size were the predictive factors of the effectiveness of CBT.

LIMITATIONS

The heterogeneity of most meta-analyses was high (I2 > 75 %).

CONCLUSIONS

Although CBT is effective in treating BDD, there is insufficient evidence to suggest that it is the best psychological intervention for BDD. More high-quality evidence is still needed in the future.

Enhancing self-esteem in adults with body dysmorphic symptoms: experimental testing and initial evaluation of a brief internet-based training

BACKGROUND

Low self-esteem is an important factor associated with body dysmorphic concerns. In treatment, self-esteem cannot always be adequately addressed. Internet-based interventions offer a low-threshold and cost-efficient possibility for treating body dysmorphic disorder (BDD).

AIMS

For this reason, we conducted two studies to explore the effectiveness of an internet-based intervention targeting improving self-esteem in adults with BDD symptoms.

METHOD

The first study investigated the differential effects of a 1-week self-esteem training compared with a 1-week attention-focus training. Two hundred twenty adults with elevated body dysmorphic symptoms were randomly assigned to one of the two trainings. Our second study (n = 58 adults with body dysmorphic symptoms) evaluated an extended 2-week stand-alone self-esteem training.

RESULTS

In the first study, self-esteem in different domains (appearance, performance and social), self-focused attention, and BDD symptom severity improved in both groups. Other-focused attention only increased in the attention training group. Participants' overall adherence was high. In the second study we observed significant improvements in self-esteem, BDD symptom severity, and other secondary outcomes, with additional improvements in most outcomes in the second week. Adherence was again high.

CONCLUSIONS

Together, these findings show that a brief internet-based intervention may be a highly accepted and effective way of improving self-esteem in people suffering from BDD symptoms.

Epidemiology of Body Dysmorphic Disorder and Appearance Preoccupation in Youth: Prevalence, Comorbidity and Psychosocial Impairment

OBJECTIVE

Little is known about how common and impairing body dysmorphic disorder (BDD) is in the general population of youth. We evaluated the prevalence, comorbidity, and psychosocial impairment associated with BDD and more broadly defined appearance preoccupation in young people.

METHOD

Data were drawn from the 2017 Mental Health of Children and Young People in England survey. BDD and psychiatric comorbidity were assessed in individuals 5 to 19 years of age (N = 7,654) according to DSM-5 criteria, using a clinician-rated standardized diagnostic assessment. Psychosocial impairment was measured with a quantitative scale and was indexed by reported self-harm and suicide attempts, as well as service use, assessed using structured interviews.

RESULTS

The point prevalence of BDD was 1.0% (95% CI = 0.8%-1.3%). BDD was significantly more common among adolescents than children (1.9 vs 0.1%; OR = 22.5, p < .001), and among female than male participants (1.8% vs 0.3%; OR = 7.3, p < .001). Approximately 70% of young people with BDD had psychiatric comorbidity, most commonly internalizing disorders. BDD was associated with self- and parent-reported psychosocial impairment, self-harm and suicide attempts, and service utilization. Appearance preoccupation was more common than full-syndrome BDD, but showed similar age and sex effects, patterns of comorbidity, and associated impairment.

CONCLUSION

BDD and appearance preoccupation are relatively common, especially among adolescent girls, and are associated with substantial co-occurring psychopathology, impairment, and risk. Improved screening is needed to increase detection and diagnosis of BDD, and to facilitate access to evidence-based treatment.

Development of a body dysmorphic disorder screener for DSM-5 (BDDS-5)

Early identification of individuals with Body dysmorphic disorder (BDD) is essential to direct them to appropriate care and to reduce the chance of developing or maintaining comorbid psychiatric disorders (like an eating disorder (ED)). The present study aimed to develop a simple screener, the Body Dysmorphic Disorder Screener for DSM-5 (BDDS-5), to overcome existing screeners' limitations and test its psychometric properties. The BDDS-5 consists of 12 statements with dichotomous answer options. Specific attention is paid to the readability of the screener for those with lower reading skills. Additional eating disorder screening questions (S section) were added to investigate whether these questions are necessary for detecting potential BDD cases. Finally, the factor structure, internal consistency, and validity of the BDDS-5 were examined within populations with a high risk of screening positive for BDD or ED. Principal axis factor analysis showed that two factors accounted for 63.5% of the variance. The factor analysis was based on polychoric correlation. Based on the BDDS-5, 33 persons (14% of N = 235) were screened as likely BDD cases. Nineteen persons were excluded as potential BDD cases based on the eating disorder related question (question D). Based on the S-section, this turned out to be largely correct for the majority, however, in 8% (n = 4) of the cases BDD was probably missed. The convergent validity appeared to be high (r > 0.80) with three other BDD measures. The BDDS-5 is a valid and widely applicable screener for BDD that may help in the early detection of BDD. The BDDS-5 uses simple wording and is thus suitable for people 8 years and older.

Prevalence of body dysmorphic disorder: A systematic review and meta-analysis

Body dysmorphic disorder (BDD) is characterised by a preoccupation with a perceived defect in appearance. This preoccupation results in the completion of repetitive/time consuming behaviours to reduce distress. While the disorder results in considerable distress and impairment, the prevalence of the disorder is largely unknown, as BDD has not been examined in large epidemiological studies. The aim of the current study was to provide an estimate of BDD prevalence in a variety of settings using a meta-analytic approach using only studies that have made a diagnosis using a structured diagnostic interview. Twenty-two studies met criteria (n = 7159) and the pooled point-prevalence estimate for BDD was 11.3% across all studies with high levels of heterogeneity (I2 = 95.81). The pooled point-prevalence estimate was 20.0% in cosmetic/dermatology settings, 7.4% in mental health settings, and 6.7% in 'other' settings (including students and professional ballet dancers). The risk of bias assessment indicated questionable methodological quality in some of the included studies. While this study provides an important improvement on the existing literature there is a need to include BDD in epidemiological studies in order to have a more accurate understanding of the prevalence rate of this mental health condition in the community.

Internet-Based Treatment of Body Dysmorphic Disorder: Feasibility, Evaluation, and Self-Report Data

ABSTRACT

Initial findings indicate the effectiveness of internet-based interventions for body dysmorphic disorder (BDD). In order to substantiate these findings, a seven-module guided internet-based intervention was created and examined. We report the mixed data of participants with clinical and subclinical BDD of the treatment group (n = 18). We investigated the feasibility, the quality of the program content, the design and usability, and its effects on symptom severity and related psychopathology. Adherence to the intervention was low and dropout rate high (55.6%). The program content, perceived website usability, and visual aesthetic were rated high. Credibility and expectancy were on a medium level. Satisfaction with appearance improved significantly in the intention-to-treat analysis (d = 0.58). In sum, symptom-related outcomes and program evaluation showed a positive trend albeit the study conduction was difficult. Future programs should investigate the role of additional motivation strategies and more flexible support addressing the known treatment barriers.

Body Dysmorphic Disorder

This article summarizes current knowledge of body dysmorphic disorder across the life span. An overview of the epidemiology and phenomenology of this condition is provided, as well as clinical perspectives on assessment and treatment. Barriers to accessing treatment are considered, along with recent developments to improve access. Future directions in research and clinical care for this population are summarized.

The associations between autistic traits and disordered eating/drive for muscularity are independent of anxiety and depression in females but not males

Previous research has shown a positive correlation between autistic traits and eating disorder symptoms, and this relationship appears to be independent of co-occurring mental health status. The current study followed a pre-registered analysis plan with the aim to investigate a previously unconsidered factor in the relationship between autistic traits and disorders of eating and body image: the drive for muscularity. Participants (N = 1068) completed the Autism Spectrum Quotient (AQ), Hospital Anxiety and Depression Scale (HADS), Eating Attitudes Test-26 (EAT-26) and Drive for Muscularity Scale (DMS). Positive correlations between AQ and EAT-26 and AQ and DMS were observed. In females, AQ remained significantly correlated with EAT-26 and DMS when controlling for co-occurring anxiety and depression symptoms, but this was not the case in males. These findings demonstrate the moderating role of sex, and the need to consider autistic traits in individuals diagnosed with, or at a heightened risk for, disorders of eating and body image.

Body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms in a large sample of adolescents

Few studies have investigated body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms in adolescents and how they relate to mental health, quality of life, suicide attempts, and non-suicidal self-harm. We used a quota sampling procedure and contacted 100 secondary centres in the Southeast of Spain, of which 34 participated in the study. A sample of 5,345 adolescents (12–18 years) completed dimensional measures of body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms. The proportion of adolescents with clinically significant symptoms within each symptom type was estimated and associations with other indicators of mental health examined. Clinically significant body-dysmorphic symptoms were reported by 3.7%, hoarding by 0.9%, hair-pulling by 0.7%, and skin-picking by 1.8%. Body-dysmorphic symptoms were more common in girls and in those over 14 years of age. Body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms were moderately to strongly associated with obsessive-compulsive symptoms, internalizing symptoms, externalizing symptoms, and poor quality of life. Those with significant body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms were much more likely to have attempted suicide and engaged in non-suicidal self-harm during the last twelve months than those without such symptoms. Body-dysmorphic symptoms showed the strongest associations with internalizing symptoms and poor quality of life. Limitations are the sole use of self-report and a sample from only two regions in Spain, but findings suggest that body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms are common and impairing during adolescence.

Future of mental health in the metaverse

The metaverse and non-fungible tokens (NFTs) were some of the hottest tech terms in 2021, according to a Google Trends search. Our review aims to describe the metaverse and NFTs in the context of their potential application in the treatment of mental health disorders. Advancements in technology have been changing human lives at an ever-increasing pace. Metaverse, also known as the three-dimensional (3D) internet, is the convergence of virtual reality (VR) and physical reality in a digital space. It could potentially change the internet as we know it, with NFTs as the key building blocks in the new expansive virtual ecosystem. This immersive 3D virtual world boasts the features of the real world with the added ability to change the surrounding environment according to individual needs and requirements. VR, augmented reality (AR) and mixed reality (MR) have been employed as tools in the treatment of various mental health disorders for the past decade. Studies have reported positive results on their effectiveness in the diagnosis and treatment of mental health disorders. VR/AR/MR have been hailed as a solution to the acute shortage of mental health professionals and the lack of access to mental healthcare. But, on the flip side, young adults tend to spend a significant amount of time playing 3D immersive games and using social media, which can lead to insecurity, anxiety, depression, and behavioural addiction. Additionally, endless scrolling through social media platforms negatively affects individuals' attention span as well as aggravating the symptoms of adolescents with attention deficit hyperactivity disorder.

We aimed to explore the ramifications of expanding applications of the metaverse on mental health. So far, no other review has explored the future of mental health in the context of the metaverse.

Psychedelic therapy for body dysmorphic disorder

In this opinion piece we propose the investigation of psychedelic-assisted psychotherapy for the treatment of body dysmorphic disorder (BDD). BDD is a psychiatric disorder characterised by appearance-based preoccupations and accompanying compulsions. While safe and effective treatments for BDD exist, non-response and relapse rates remain high. Therefore, there is a need to investigate promising new treatment options for this highly debilitating condition. Preliminary evidence suggests safety, feasibility, and potential efficacy of psychedelic treatments in disorders that share similar psychopathological mechanisms with BDD. Drawing on this evidence, as well as on relevant qualitative reports and theoretical proposals, we argue that it would be worthwhile to conduct a phase 2a study aimed at assessing the safety and feasibility of psychedelic-assisted psychotherapy in BDD. We also offer some suggestions for how future research ought to proceed.

Telephone-Administered Cognitive Behavioral Therapy for Body Dysmorphic Disorder: Case Series

Cognitive behavioral therapy is an effective treatment for body dysmorphic disorder (BDD), but many patients do not receive appropriate treatment due to several treatment barriers and psychosocial care structures. Low-threshold interventions, including those from the field of e-mental health, could improve access to psychotherapy. In addition to internet-administered therapy, telephone-administered therapy may reduce treatment barriers, especially during the COVID-19 pandemic. This article presents four case reports of the same treatment (12 weeks of telephone-administered cognitive behavioral therapy accompanied by a workbook) applied to patients with body dysmorphic disorder during the summer of 2020. Three patients who completed the treatment had clinically relevant reductions in body dysmorphic and depressive symptoms and improved insight. One patient did not complete the telephone-administered therapy because her symptoms worsened, and she needed a more intensive form of treatment. These findings encourage future studies on the efficacy and effectiveness of telephone-administered treatment for BDD and its role in stepped-care models.

Efficacy of App-Based Cognitive Behavioral Therapy for Body Dysmorphic Disorder with Coach Support: Initial Randomized Controlled Clinical Trial

INTRODUCTION

Body dysmorphic disorder (BDD) is severe, chronic, and undertreated. Apps could substantially improve treatment access.

OBJECTIVE

We provide an initial test of the usability and efficacy of coach-supported app-based cognitive behavioral therapy (CBT) for BDD. The Perspectives app covers core treatment components: psychoeducation, cognitive restructuring, exposure with response prevention, mindfulness, attention retraining, and relapse prevention.

METHODS

A randomized waitlist-controlled trial was conducted. Adults (N = 80) with primary BDD were assigned to 12 weeks of Perspectives or waitlist. Coaches promoted engagement and answered questions via in-app messaging and phone calls. BDD severity was measured at baseline, mid-treatment, and end of treatment by blinded independent evaluators (Yale-Brown Obsessive Compulsive Scale Modified for BDD; BDD-YBOCS). Secondary outcomes included BDD-related insight, depression, quality of life, and functioning.

RESULTS

App uptake and satisfaction were high. In intent-to-treat analyses, Perspectives app-based CBT was associated with significantly lower BDD-YBOCS severity at end of treatment (M [SD]: 16.8 [7.5]) compared to the waitlist (26.7 [6.2]; p < 0.001, d = 1.44). App-based CBT was associated with greater improvements across all secondary measures, with medium to large effects.

CONCLUSIONS

Perspectives, supported by a bachelor's-level coach, is an efficacious, scalable treatment for adults with BDD.

"Motivations, demography and clinical features of body dysmorphic disorder among people seeking cosmetic treatments: a study of 199 patients."

BACKGROUND

Motivations for getting aesthetic medicine treatments concern not only the improvement of the physical appearance but also internal aspects such as feeling more confident or happier. Body dysmorphic disorder (BDD) is a disorder that affects from 5 to 15% of aesthetic medicine clients and characterizes by an obsessive preoccupation with a non-visible or minimal defect in appearance.

AIMS

The aim of the study was to assess the main motivations, demography, and clinical features of body dysmorphic disorder among people seeking cosmetic treatments.

METHODS

A single-center study was performed using an anonymous questionnaire on 199 patients of the private aesthetic medicine clinic in Gdansk, Poland.

RESULTS

A typical client of an aesthetic clinic is a woman aged 40 to 50, with higher education, who undergoes aesthetic treatments more than twice a year, mainly with botulinum toxin injections. The most common motivations are the desire to achieve a fresh look, the will to reduce the signs of aging, and to invest in oneself. Furthermore, over 38% of patients stated that they were having critical and recurring thoughts about their appearance, which affected their daily functioning and caused a decrease in their well-being. Almost 20% of them performed repetitive activities, such as frequently looking in the mirror or asking others for opinions about their appearance. 15.6% of patients presented at least two characteristic features of BDD.

CONCLUSIONS

Patients seeking cosmetic treatments may suffer from body dysmorphic disorder, thus the need for aesthetic medicine practitioners to be aware of this disease.

A smartphone app for the prevention and early intervention of body dysmorphic disorder: Development and evaluation of the content, usability, and aesthetics

Body dysmorphic disorder (BDD) is an impairing condition characterized by excessive appearance concerns that frequently begin in adolescence, thus making this phase an eminent target for prevention and early intervention. We developed a cognitive-behavioral app-based program (AINA) intended for prevention and early intervention of BDD. As part of the iterative development process, perceptions of usability, aesthetics, and content were investigated. A sample of 38 adolescents and young adults aged between 14 and 21 years tested the app in a laboratory setting and completed a survey of diagnostic and user experience questionnaires. Overall, usability, aesthetics, and content of the app received positive evaluations. Regression analyses did not point to any large effects of age, gender, years of education, self-esteem, or BDD symptom severity on user evaluations. On average, participants had no concerns about privacy or data security of the app, indicating that these aspects will presumably not act as barriers to usage. Altogether, the present results are encouraging. Future research needs to examine whether AINA is an efficacious measure for prevention and early intervention of BDD.

BDD-NET – Ein internetbasiertes Programm bei Körperunzufriedenheit zur niedrigschwelligen Behandlung der körperdysmorphen Störung für den deutschen Sprachraum

Hintergrund: Die Körperdysmorphe Störung (KDS) ist eine schwerwiegende psychische Störung, die mit starker Scham sowie Leidensdruck und Funktionseinschränkungen einhergeht. Kognitive Verhaltenstherapie stellt die aktuell wirksamste evidenzbasierte Behandlungsmethode dar. Aufgrund zahlreicher Behandlungsbarrieren kommen KDS-Betroffene jedoch selten in der psychotherapeutischen Behandlung an, weshalb niedrigschwelligen Behandlungsmethoden (z.B. aus dem Bereich E-Mental-Health) eine wichtige Rolle zukommen könnten. Erste internationale Studien weisen auf die Wirksamkeit von E-Mental-Health-Angeboten bei KDS hin. Material und Methoden: Dieser Beitrag gibt eine Übersicht zur bisherigen Umsetzung und Evidenz von E-Mental-Health-Angeboten für KDS und stellt die ins Deutsche übersetzte Version des BDD-NET-Programms, eines internetbasierten, manuali­sierten, therapeutenbegleiteten Interventionsprogramms, für die KDS vor, welches aus dem Englischen für den deutschen Sprachraum übersetzt und adaptiert wurde. Ergebnisse: BDD-NET umfasst acht Module, die binnen einer 12-wöchigen Behandlung online bearbeitet werden. Die Online-Plattform bietet für die Patienten die Möglichkeit, mit dem BDD-NET-Therapeuten mittels persönlicher Nachrichten zu kommunizieren. Sämtliche Materialien wurden aus dem Englischen übersetzt und vor allem in kultureller Hinsicht adaptiert. Schlussfolgerungen: BDD-NET könnte ein wichtiger Baustein in der Versorgung von KDS-Betroffenen sein. Die Evaluation steht für den deutschen Sprachraum noch aus. Auf Besonderheiten des Settings (z.B. Störungseinsicht als möglicher Behandlungsfokus) sowie praktische Implikationen wird eingegangen. Zudem werden Voraussetzungen und Rahmenbedingungen für eine perspektivische Dissemination diskutiert.

The relationship between body dysmorphic disorder symptoms and 'not just right' experiences in a sample of individuals seeking cosmetic surgery and aesthetic medicine procedures

BACKGROUND

Body dysmorphic disorder (BDD) is characterized by concerns for perceived defects in physical appearance that appear to others as mild or unobservable. Individuals with BDD frequently refer concerns with their physical appearance being 'not right' (not just right experiences; NJREs), and BDD-related behaviours may be performed until their appearance is perceived as 'right'. The aim of the study was to explore the relationship between BDD and NJREs in cosmetic surgery and aesthetic medicine settings.

METHODS

Individuals requesting cosmetic procedures with BDD symptoms (BDD-symptoms group; n = 24), without BDD symptoms (cosmetic intervention [CI] group; n = 45), and individuals that have never required these procedures (no cosmetic intervention [NCI] group; n = 53) entered the study.

RESULTS

Results showed a greater number of past-month NJREs, higher NJREs severity, higher drive for thinness, and greater general distress in the BDD-symptoms group. Pertaining to features associated with NJREs (perfectionism and obsessive-compulsive disorder symptoms) and ED core features, the BDD-symptoms group scored higher only with respect to NCI. Regression analyses showed that BDD symptoms were predicted by age, NJREs severity, and drive for thinness above and beyond general distress, perfectionism, obsessive-compulsive disorder symptoms, bulimia, and body dissatisfaction related to weight and shape in the BDD-Symptoms group (in comparison with the CI and NCI groups).

CONCLUSIONS

NJREs may represent a potential vulnerability factor for BDD symptoms in cosmetic settings.

Are body dysmorphic symptoms dimensional or categorical in nature? A taxometric investigation in adolescents

Body dysmorphic disorder (BDD) is a debilitating mental health condition which usually emerges during adolescence and is characterised by distressing and impairing appearance concerns. It is currently unclear whether body dysmorphic concerns represent an extreme manifestation of normal appearance concerns (a dimensional conceptualisation), or whether they are qualitatively distinct (a categorical conceptualisation). This study aimed to determine whether body dysmorphic symptoms are dimensional or categorical in nature by investigating the latent structure using taxometric procedures. Body dysmorphic symptoms were assessed using validated measures among 11-16-year-old school pupils (N=707). Items of the Body Image Questionnaire Child and Adolescent version were used to construct four indicators that broadly corresponded to the DSM-5 diagnostic criteria for BDD (appearance concerns, repetitive behaviours, impairment, and insight). Indicators were submitted to three non-redundant taxometric procedures (MAMBAC, MAXEIG and L-MODE). Overall, results of all three taxometric procedures indicated a dimensional latent structure of body dysmorphic symptoms. The current study provides preliminary evidence that body dysmorphic symptoms are continuously distributed among adolescents, with no evidence of qualitative differences between mild and severe symptoms. Implications for clinical practice and research are discussed.

Suicidality in patients with obsessive-compulsive and related disorders (OCRDs): A meta-analysis

INTRODUCTION

Previous meta-analyses showed that OCD is associated with a substantial risk of suicidal behaviours. Conclusive rates of suicidal ideation (current and lifetime) and suicide attempts based on pooled prevalence rates have not so far been calculated using meta-analysis for the other DSM-5 Obsessive-Compulsive and Related Disorders (OCRDs).

OBJECTIVES

This meta-analysis aims to separately calculate the pooled prevalence rates of lifetime suicide attempts and current or lifetime suicidal ideation in BDD, Hoarding Disorder (HD), Skin Picking Disorder (SPD) and Trichotillomania (TTM) and to identify factors associated with increased suicide rates.

METHODS

Our protocol was pre-registered with PROSPERO (CRD42020164395). A systematic review and meta-analysis following PRISMA reporting guidelines was performed by searching in PubMed/Medline, PsycINFO, Web of Science and CINAHL databases from the date of the first available article to April 20th, 2020. Stata version 15 was used for the statistical analysis. Given the small number of studies in TTM and SPD, the two grooming disorders were grouped together. Meta-analyses of proportions based on random effects (Der-Simonian and Laird method) were used to derive the pooled estimates.

RESULTS

Thirty-eigth studies (N = 4559 participants) were included: 23 for BDD, 8 for HD, 7 for Grooming Disorders. For BDD, the pooled prevalence of lifetime suicide attempts, current and lifetime suicidal ideation was, respectively 35.2% (CI:23.4-47.8), 37.2% (CI:23.8-51.6) and 66.1% (CI:53.5-77.7). For HD, the pooled prevalence of lifetime suicide attempts, current and lifetime suicidal ideation was 24.1% (CI:12.8-37.6), 18.4% (CI:10.2-28.3) and 38.3% (CI:35.0-41.6), respectively. For Grooming Disorders, the pooled prevalence of lifetime suicide attempts and current suicidal ideation were 13.3% (CI:5.9-22.8) and 40.4% (CI:35.7-45.3), respectively (no data available for lifetime suicidal ideation).

CONCLUSIONS

The OCRDs as a group are associated with relatively high rates of suicidal behaviour. Through indirect comparisons, we infer that BDD has the greatest risk. Comorbid substance abuse, possibly reflecting poor underlying impulse control, is associated with higher rates of suicidal behaviour in BDD. Our data emphasize the need for clinicians to consider the risk of suicidal behaviour in the management of patients presenting with all forms of OCRDs.

ImaginYouth-A Therapist-Guided Internet-Based Cognitive-Behavioral Program for Adolescents and Young Adults With Body Dysmorphic Disorder: Study Protocol for a Two-Arm Randomized Controlled Trial

Background: Body dysmorphic disorder (BDD) is a relatively common mental disorder in adolescents and young adults, and is characterized by severe negative psychosocial consequences and high comorbidity as well as high mortality rates, mainly due to suicides. While patients in Germany have health insurance-financed access to evidence-based outpatient treatments, that is, cognitive-behavioral treatment (CBT), waiting lists are long. Furthermore, patients with BDD report diverse treatment barriers, primarily feelings of shame and the belief that they would be better off with treatments that would alter the perceived flaw(s). Given adolescents' and young adults' high affinity to electronic media, the accessibility of evidence-based care for this severe mental disorder could be improved by providing an internet-based therapist-guided CBT intervention. Methods: In a two-arm randomized controlled trial (N = 40), adolescents and young adults (15-21 years) with a primary diagnosis of BDD based on a semi-structured clinical expert interview will be randomly allocated to an internet-based therapist-guided CBT intervention or a supportive internet-based therapy intervention. Assessments will take place at baseline, after mid-intervention (after 6 weeks), post-intervention, and at 4-week follow-up. The primary outcome is expert-rated BDD symptom severity at the primary endpoint post-intervention. Secondary outcomes include responder and remission rates based on expert rating, self-reported BDD symptoms, and psychosocial variables associated with BDD. Interventions: The CBT-based intervention consists of six modules each comprising one to three sessions, which focus on psychoeducation, cognitive restructuring, work on self-esteem, exposure and ritual prevention, mirror retraining, and relapse prevention. A study therapist provides feedback after each session. The supportive therapy intervention consists of access to psychoeducational materials for the same 12-week period and at least one weekly supportive interaction with the study therapist. Conclusions: This is the first study to examine the feasibility and efficacy of an internet-based therapist-guided CBT intervention in adolescents and young adults with BDD. It could be an important first step to increase accessibility of care in this age group and for this severe and debilitating mental disorder.

The relationship between obsessive-compulsive spectrum disorders and DSM-5 dysfunctional personality domains in a nonclinical sample of Italian women

To evaluate the usefulness of the DSM-5 maladaptive personality domains in explaining the similarities and differences among four disorders included in the obsessive-compulsive spectrum, 428 Italian community-dwelling women (mean age = 31.96 years, SD = 12.30 years) were administered the Obsessive-Compulsive Spectrum Disorder Scales and the Personality Inventory for DSM-5-Short Form as part of an ongoing online survey on women's health. Multiple Indicators Multiple Causes (MIMIC) confirmatory bifactor analysis results showed that the OCSD general factor (i.e., obsessive-compulsive spectrum factor) was positively associated with Negative Affectivity, whereas Body Dysmorphic Disorder (BDD), Hoarding Disorder (HD), and Skin-Picking Disorder (SPD) specific factors showed significant and substantial differential relationships with dysfunctional personality domains. Specifically, BDD was positively associated with Negative Affectivity, Detachment and Psychoticism domains; HD was associated with high Negative Affectivity and Psychoticism; and SPD was associated with Detachment. © 2020 John Wiley & Sons, Ltd.

Two Case Studies of Delusions Leading to Suicide, a Selective Review

Many questions pertaining to delusional disorder (DD) remain unanswered. It is unclear what syndromes to include under this category of psychotic illness and when to treat with antidepressants, cognitive therapy, or antipsychotic medication. DD is associated with psychiatric comorbidity, especially depression, and rates of suicidal behavior are high when the two conditions co-exist. In this selective review, we present two instances of suicide in the context of DD, one illustrating risks for the somatic subtype and the second, risks for the persecutory subtype. The frequency of suicidal behaviour in these two subtypes of DD is estimated at 8-21%. The literature suggests a prominent role for social emotions (shame, humiliation) in the pathway leading to suicide. In addition, risk factors found in our two patients point to factors such as poverty, living alone, vulnerable risk periods, stigma, and lack of trust in mental health services. Building trust may be the most effective preventive measure.
