Prevalence and correlates of imposter syndrome and self-esteem among medical students at Jazan University, Saudi Arabia: A cross-sectional study.

Imposter syndrome (IS) and low self-esteem (SE) are common issues affecting medical students that can impact their well-being and development. This study aimed to assess the prevalence and factors associated with IS and SE among medical students at Jazan University, Saudi Arabia. In this cross-sectional study, 523 medical students in years 2-6 at Jazan University, Saudi Arabia, completed validated questionnaires on IS (Young Imposter Scale) and SE (Rosenberg Self-Esteem Scale). Sociodemographic factors were also collected. Descriptive statistics and logistic regression analyses were used to analyze IS and SE prevalence and correlates. Five hundred twenty-three students with a mean age of 22.09 ± 1.933 participated. The prevalence of low SE and positive IS was 17.6% and 24.3%, respectively. IS and SE had a significant negative correlation (p<0.001). Several sociodemographic factors were associated with increased IS, including 2nd and 4th-year students, forced study choice, and a grade point average (GPA) of 3.0-3.49 (P<0.05). Paternal education beyond high school was associated with lower IS (P<0.05). Logistic regression analyses confirmed that 2nd-year students had a 3.88 times higher odds ratio (OR) (95% confidence interval (CI); 2.19-6.88), and 4th-year students had a 2.37 times higher OR (95% CI; 1.40-4.02) of IS than other years. For SE, advanced academic years, forced study choice, 7+ hours of sleep, and a GPA above 3.5 were associated with higher levels (P<0.05). Negative self-appraisals were associated with lower SE, while positive attitudes were associated with higher SE (P<0.05). Our study reveals that IS and low SE are prevalent among Jazan University, Saudi Arabia, medical students. Therefore, intervention courses that address these issues in medical education at Jazan University, Saudi Arabia, may be necessary to support medical students' well-being and academic success.

Body Image, Nutrition, and Mental Health.

Classical examples of disorders associated with body image disturbances are eating disorders (EDs) such as anorexia nervosa (AN) and bulimia nervosa (BN), as well as body dysmorphic disorder (BDD) [...].

Beyond the surface: Understanding obsessive symptoms and body perceptions, from shape concerns to fear of blushing.

INTRODUCTION: Recent reclassifications have expanded the understanding of Obsessive-Compulsive Disorders (OCDs), now incorporated into a broader category known as Obsessive-Compulsive Disorder and Related Disorders (OCRDs). This study sought to assess obsessive-compulsive symptoms and body uneasiness among outpatients seeking treatment for Eating Disorders (ED). Additionally, we aimed to explore associations and potential mediation effects between obsessive-compulsive symptoms and body uneasiness. This investigation extended beyond concerns related solely to body shape and weight, encompassing fears associated with specific body components (such as facial features, abdominal region, and limbs) or functions (including sweating, blushing, emitting noises, and releasing odors). METHODS: Psychometric assessments included the Obsessive-Compulsive Inventory-Revised (OCI-R) and the Body Uneasiness Test (BUT). Statistical analyses involved bivariate correlations, linear regression, and mediation analysis to explore the associations and potential mediation effects between obsessive-compulsive symptoms and different manifestations of body uneasiness. RESULTS: The sample (N = 210) demonstrated substantial obsessive-compulsive symptoms and notable body discomfort. OCI-R scores positively correlated with various dimensions of body dissatisfaction, including shape, weight, and specific body components or functions. Linear regression revealed significant associations between OCI-R scores and overall body uneasiness (BUT-A) as well as concerns about body components or functions (BUTB). Mediation analysis indicated that BUT-A mediated the relationship between obsessive-compulsive symptoms and BUTB. CONCLUSION: This study offers new insights into the comprehensive landscape of OCRDs. It specifically emphasizes the association between obsessive-compulsive symptoms and body uneasiness, embracing not only concerns about body shape and weight but also extending to body components and functions.

Investigating the prevalence of body dysmorphic disorder among Jordanian adults with dermatologic and cosmetic concerns: a case-control study.

Body Dysmorphic Disorder (BDD) is an underexplored psychiatric condition in Middle Eastern countries, particularly in patients with dermatologic concerns, where alterations in appearance may elevate the risk of BDD. We studied patients at Jordan University Hospital's general dermatology and cosmetic clinics from July to September 2022, comparing them to healthy controls. Patients with dermatologic conditions were evaluated per the International Classification of Diseases (ICD-10) criteria by trained dermatologists. All participants completed the Dysmorphic Concerns Questionnaire (DCQ), Perceived Stress Scale, Patient Health Questionnaire-2, General Anxiety Disorder Assessment tool-2. We assessed BDD prevalence using four DCQ cutoffs: 9, 11, 14, and 17, reporting effect sizes as odds ratios (OR). Our study involved 1500 participants, with an average age of 29.3 (± 14.8) years and a female-to-male ratio of 3.15-to-1. At the 9, 11, 14, and 17 DCQ cutoffs, BDD prevalence was 78.2%, 54.2%, 26.5%, and 11.7%, respectively. Patients with dermatologic concerns were more likely to exhibit clinical BDD symptoms than controls at the 11-cutoff (OR: 1.26; 95% CI 1.01-1.58; p < 0.05). Conversely, those with cosmetic concerns were more prone to clinical BDD than controls at cutoffs 9 (OR: 2.26; 95% CI 1.28-3.97; p < 0.05) and 11 (OR: 1.50; 95% CI 1.03-2.20; p < 0.05). Our logistic regression revealed consistent associations between higher DCQ scores and elevated anxiety, depression, perceived skin disease-related stigma, and reduced quality of life (p < 0.05). In conclusion, patients with dermatologic issues and those seeking cosmetic procedures are at significant risk of developing BDD, necessitating proactive screening and referrals for specialized care by dermatologists due to the associated psychological distress and unproductive consultations. Providing specialized training for healthcare professionals to establish an integrated care approach to address the needs of patients with BDD should be the focus of future research projects.

Predicting response to a smartphone-based cognitive-behavioral therapy for body dysmorphic disorder.

BACKGROUND: Body dysmorphic disorder (BDD) is a severe, chronic disorder if untreated. Smartphone cognitive behavioral therapy (CBT) for BDD is efficacious and can reduce key treatment barriers (e.g., lack of clinicians, cost, stigma). While promising, little is known about who is more or less likely to benefit from this approach. METHODS: This is a secondary data analysis of a randomized, waitlist-controlled trial of smartphone CBT for BDD. Participants (N = 80) were recruited nationally and randomized to receive a 12-week, coach-guided CBT for BDD app, either immediately or after a 12-week waitlist. The main outcome for this analysis was BDD severity (BDD-YBOCS) over time (baseline, week 6, week 12) during the active app use phase in each randomized group (n = 74). Secondary outcomes included treatment response (≥30 % reduction in BDD-YBOCS) and remission (total BDD-YBOCS ≤16) at end-of-treatment. RESULTS: Immediate (vs. delayed) CBT predicted better outcomes (symptom improvement), as did gender identity (symptom improvement), higher baseline treatment credibility and expectancy (response, remission), lower baseline BDD severity (remission), and sexual minority status (vs. heterosexual; response, remission). LIMITATIONS: Limitations include the relatively small sample, drop-out rate of 22 %, and limited gender and racial-ethnic diversity. CONCLUSIONS: These results highlight a potential advantage of smartphone CBT in historically marginalized populations, and the importance of efforts to hasten treatment access, bolster confidence in the treatment at treatment onset, and develop stratified care models to optimize treatment allocation and efficacy.

The association between use of social media and the development of body dysmorphic disorder and attitudes toward cosmetic surgeries: a national survey.

Introduction: Body dysmorphic disorder (BDD) causes distress due to one's negative appraisal of their body image. The development of BDD has been linked to the passive use of social media and photo-editing apps. People with BDD typically pursue cosmetic surgeries to remedy their perceived flaws. The dramatic increase in the use of photo-editing apps and their well-established effects on mental health is a public health concern. Purpose: To study the association between use of social media and the development of BDD and acceptance toward cosmetic surgeries (ACSS) among Saudis. Methods: An online, cross-sectional, validated survey conducted among Saudis 18 and older. Descriptive analyses were utilized for demographics and prevalence rates of main study variables. ANOVA was used to compare mean scores in BDD and ACSS among different demographic groups. Tukeys post-hoc test was done to identify the categories that were different when the ANOVA test showed a statistically significance. A p-value of <0.05 was considered statistically significant. Results: A total of 1,483 Saudi adults completed the questionnaire. Key results showed that BDD was found in 24.4 % of the sample. The percentage of participants with BDD who spent 4-7 h per day on Instagram and Snapchat (29%) was significantly higher than those who spent only less than an hour per day on these platforms (19%) (p < 0.001). Individuals with BDD had a significantly higher risk of accepting cosmetic surgery compared to those without BDD (p < 0.001). Conclusion: A growing body of evidence suggests that social media may impact mental health in different ways. This study reveals that heavy use of these platforms is associated with negative appraisals about one's physical appearance, and it fosters one's tendency toward cosmetic surgery, especially among females.

Associations between muscle dysmorphia symptomatology and sleep duration and difficulty in the Canadian Study of Adolescent Health Behaviors.

OBJECTIVES: Prior research has shown links between mental health symptomatology and poor sleep. However, associations between muscle dysmorphia symptomatology and poor sleep remain unknown, which was the aim of this study. METHODS: Data from the Canadian Study of Adolescent Health Behaviors (2021-2022) were analyzed (N = 912). Multinomial logistic regression analyses and logistic regression analyses were used to determine the association between muscle dysmorphia symptomatology and average sleep duration (5 hours or less, 6 hours, 7 hours, and 8 or more hours) and difficulty falling or staying asleep over a 2-week period. RESULTS: Findings indicated significant associations between muscle dysmorphia symptomatology and shorter sleep duration and greater sleep difficulty in both cross-sectional and prospective analyses. CONCLUSIONS: The findings from this study underscore poor sleep as a correlate of muscle dysmorphia symptomatology among adolescents and young adults, emphasizing the need for screening and interventions in healthcare settings.

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.

Time to Response in Therapy for Body Dysmorphic Disorder: A Comparison of Cognitive Behavioral Therapy and Supportive Psychotherapy.

Psychotherapy has been shown to be effective for individuals with body dysmorphic disorder (BDD); however, time to treatment response for different treatments have not yet been examined. We randomized 120 patients to either weekly cognitive behavioral therapy (CBT) or supportive psychotherapy (SPT) at two academic medical research centers. In this secondary data analysis, we aimed to determine the time to first response (30% or greater reduction in BDD symptom severity) in both treatment conditions among those who attended at least one post-baseline assessment (n = 109). As previously reported, CBT for BDD was associated with more consistent improvement in symptom severity and quality of life than SPT. In a pooled analysis combining both sites, the median time to first response was shorter for CBT (76 days [10.9 weeks], 95% CI: 76-107 days) than for SPT (88 days [12.6 weeks], 95% CI: 88-nonestimable days; Χ2df=1 = 3.85, p = .0498). For CBT, the estimated 75th percentile response times were 148 days [21.1 weeks] at site 1 and 134 days [19.1 weeks] at site 2. Response times were not estimable for SPT at either site because the response rate was too low. Thus, therapy clients seeking treatment for BDD and clinicians should be aware that an initial treatment response requires more than 11 therapy sessions for the majority of clients, and that 21 or even more sessions may be required. Treatment response is likely to occur earlier with CBT for BDD (the first-line therapy for BDD) than with supportive psychotherapy.

Psychological evaluation of Asian female patients with rhinoplasty.

BACKGROUND: Patients requiring plastic surgery exhibit more abnormal psychological trends (e.g., body dysmorphic disorder [BDD], depression, and anxiety) than those requiring other surgeries. However, there are only a few domestic studies on the psychological aspects of the population requiring plastic surgery. Therefore, we analyzed the psychological characteristics and psychological impact of rhinoplasty in female patients. METHODS: In this study, patients were classified into 2 groups: 151 males and 60 females. The self-rating scale of body image (SSBI), self-rating anxiety scale, self-rating depression scale, and postoperative satisfaction questionnaire were used to examine the patients before and after surgery. The results were analyzed using t-test, analysis of variance, chi-square test, paired rank sum test, and Pearson correlation analysis. RESULTS: The total prevalence of BDD in female patients who underwent rhinoplasty was 7.3%. The prevalence of anxiety disorders was 31.8% and that of depression was 45.0%. Female patients with BDD were more likely to exhibit depression (55.5%) and anxiety (36.4%). The SSBI score was related to marital status (p = 0.001) and history of rhinoplasty (p = 0.000). Moreover, there was a significant negative correlation between preoperative BDD score and postoperative satisfaction (r = -0.392, p = 0.002) as well as between the previous history of rhinoplasty and postoperative satisfaction (r = -0.603, p = 0.000). CONCLUSION: Pathological psychologies such as anxiety, depression, and BDD are common in patients scheduled to undergo rhinoplasty, and BDD is more likely to be associated with depression. Rhinoplasty has little psychological impact on patients, i.e., it neither causes improvement nor deterioration. Female patients who have undergone rhinoplasty should be considered to a have high risk of BDD. Although the outcomes of surgery are generally quite positive, patients diagnosed with BDD are more likely to be dissatisfied.

Body dysmorphic disorder among Lebanese females: A cross-sectional study.

BACKGROUND: Body dysmorphic disorder (BDD) is a mental health disorder characterized by an excessive preoccupation with perceived flaws or defects in one's appearance. This study aimed to assess the prevalence of BDD, identify the predictors of BDD, explore the associations of BDD with social anxiety and social phobia, and examine the effect of social media on BDD. METHODS: In this cross-sectional study that was conducted between January and March 2023, Lebanese adult females completed an online survey that included questions about sociodemographic characteristics, cosmetic interventions, BDD, social media use, and Social Interaction Anxiety Scale (SISA-6)/Social Phobia Scale (SPS-6). The collected information was analyzed using descriptive statistics and regression analysis. Statistical significance was set at p value <0.05. RESULTS: A sample of 1048 were eligible for analysis and the mean age was 29.94 ± 10.01 years. It was shown that 141 (13.5%) participants were BDD positive. The results of the multivariable logistic regression showed that only females living in urban areas (aOR = 2.351 [95% CI 1.502-3.680], p < 0.001), unmarried (aOR = 1.672 [95% CI 1.041-2.684], p = 0.033), reporting higher social media use score (aOR = 1.526 (95% CI 1.401-1.661), p < 0.001), and higher SIAS/SPS score (aOR = 1.040 (95% CI 1.022-1.060), p < 0.001) were significantly positively associated with BDD. CONCLUSION: This study found a high BDD prevalence (13.5%) among Lebanese adult females compared with other regions and was associated with anxiety and increased social media platforms use. This highlights the need for a comprehensive approach in the assessment of BDD, along with preventive measures to address the negative impacts of social media on well-being and promote healthy body image.

Impact of sleep disruption on BDD symptoms and treatment response.

BACKGROUND: Body dysmorphic disorder (BDD) is severe, undertreated, and relatively common. Although gold-standard cognitive behavioral therapy (CBT) for BDD has strong empirical support, a significant number of patients do not respond. More work is needed to understand BDD's etiology and modifiable barriers to treatment response. Given its high prevalence and impact on the development, maintenance, and treatment of related, frequently comorbid disorders, sleep disruption is a compelling, but not-yet studied factor. METHODS: Data were drawn from a randomized controlled trial of guided smartphone app-based CBT for BDD. Included participants were offered 12-weeks of treatment, immediately (n = 40) or after a 12-week waitlist (n = 37). Sleep disruption and BDD symptom severity were assessed at baseline, week-6, and week-12. RESULTS: Hypotheses and analysis plan were pre-registered. Two-thirds of patients reported significant insomnia symptoms at baseline. Baseline severity of sleep disruption and BDD symptoms were not related (r = 0.02). Pre-treatment sleep disruption did not predict BDD symptom reduction across treatment, nor did early sleep improvements predict greater BDD symptom improvement. Early BDD symptom improvement also did not predict later improvements in sleep. LIMITATIONS: Limitations include the small sample, restricted ranges of BDD symptom severity and treatment response, and few metrics of sleep disruption. CONCLUSIONS: Although insomnia was disproportionately high in this sample and both BDD symptoms and sleep improved in treatment, results suggest sleep and BDD symptoms may function largely independent of one another. More work is encouraged to replicate and better understand findings as well as potential challenges and benefits of addressing sleep in BDD.

Involvement in sex work is associated with muscle dysmorphia symptomatology among a sample of Canadian adolescents and young adults.

BACKGROUND: The aim of this study was to investigate the association between lifetime sex work involvement and muscle dysmorphia symptomatology. METHODS: Data from the Canadian Study of Adolescent Health Behaviours (N =912) were analysed. Multiple adjusted linear regression models were estimated with lifetime sex work involvement as the independent variable and muscle dysmorphia symptomatology, measured using the Muscle Dysmorphic Disorder Inventory, as the dependent variable. RESULTS: Among the sample, 3.7% of participants reported engaging in lifetime sex work. Significant associations were found between self-reported lifetime sex work and greater total muscle dysmorphia symptomatology (B =5.03, 95% CI 1.80, 8.26), greater Drive for Size symptomatology (B =2.36, 95% CI 0.74-3.97), and greater Functional Impairment symptomatology (B =2.11, 95% CI 0.54, 3.67), while adjusting for relevant sociodemographic variables. CONCLUSIONS: Findings from this study expand prior research that has documented poor mental health among individuals involved in sex work. Clinical and community health professionals should consider screening for muscle dysmorphia symptomatology among young people who have been involved in sex work.

The heart of it all: Body dysmorphic disorder in cosmetic surgery.

BACKGROUND: Body Dysmorphic Disorder (BDD) represents a prevalent mental health condition characterized by distress arising from self-perceived physical imperfections. BDD serves as a contraindication to aesthetic surgery. Recognizing BDD holds paramount importance for plastic surgeons, as it is instrumental in averting the exacerbation of this condition while ensuring appropriate referrals. OBJECTIVE: This study aimed to investigate the prevalence of BDD in cosmetic surgery patients and to pinpoint key characteristics associated with BDD. This information provides plastic surgeons with specific factors to consider during preoperative evaluations. METHODS: We employed TriNetX database to identify patients with BDD who underwent cosmetic surgery identified by Current Procedural Terminology codes. Demographics and patient characteristics were identified using the International Classification of Diseases 10 codes. We calculated odds ratios (OR) by using chi-squared tests to assess risk factors among patients with BDD. RESULTS: Of 226,374 patients who underwent plastic surgery between August 2002 and August 2022, fewer than 0.1% were diagnosed with BDD. Of the BDD patients, 52.1% were diagnosed after cosmetic surgery. Compared with the control group, BDD patients were more likely to undergo rhinoplasty (OR=1.784, p = 0.004) and nonlocalized lipectomy (OR=1.448, p = 0.021) and less likely to undergo blepharoplasty (OR=0.451, p = 0.002). Findings indicated a strong association between BDD patients undergoing cosmetic procedures and comorbid psychiatric conditions such as depression (OR=4.279, p < 0.05), anxiety (OR=5.490, p < 0.05), and Attention-Deficit Hyperactivity Disorder (OR=3.993, p < 0.05). CONCLUSIONS: These findings underscore the ongoing significance of BDD in the context of cosmetic surgery, potentially indicating a lower surgery rate among BDD patients compared with previous estimates. Nevertheless, avenues for further improvement persist. Our data affirm the noteworthy occurrence of postsurgery BDD development, thereby highlighting the ongoing necessity for psychiatric evaluation in surgical patients.

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.

Testing the longitudinal relationship between muscle dysmorphia symptoms and suicidality: A network analysis investigation.

Research on suicidality in muscle dysmorphia is limited despite the high rates of suicidal thoughts and behaviors in related disorders. This study employed network analysis to examine the longitudinal relationships between muscle dysmorphia symptoms, as well as the relations between MD symptoms and suicide risk factors. Fifty individuals (Mage = 30.6 years, 63 % male) meeting criteria for muscle dysmorphia received four daily surveys for three weeks. Multi-level vector autoregression analysis was used to estimate associations between muscle dysmorphia- and suicide-related thoughts, emotions, and behaviors. The most central nodes in the muscle dysmorphia networks related to assessing muscle size, dieting, using muscle-building supplements, experiencing body dissatisfaction, seeking reassurance, and avoiding others due to concerns about appearance. In the comorbidity networks, the most central suicide-related factors were feelings of burdensomeness, feeling disgusted, and dwelling on the past. Our findings indicated that various intrusive thoughts (body dissatisfaction, dieting), compulsions (seeking reassurance, body checking, supplement use), and beliefs (burden to others, disgust with oneself) predicted future engagement in muscle dysmorphia and suicide-related symptomology. Targeting intrusive thoughts and compulsions, as well as feelings of disgust and burdensomeness, may reduce the severity of these conditions.

Body Dysmorphic Disorder in Women.

Body dysmorphic disorder (BDD) consists of distressing or impairing preoccupation with perceived defects in physical appearance that are actually nonexistent or only slight. This common and often-severe disorder, which affects more women than men, frequently goes unrecognized. BDD is associated with marked impairment in functioning, poor quality of life, and high rates of suicidality. Most patients seek cosmetic treatment, which virtually never improves BDD symptoms. In contrast, serotonin-reuptake inhibitors, often at high doses, and cognitive behavioral therapy that is tailored to BDD's unique clinical features are often effective. This article provides a clinical overview of BDD, including BDD in women.

A descriptive analysis of scoring patterns on clinically relevant questionnaires in 26 adults with diagnosed muscle dysmorphia.

OBJECTIVE: Few studies have recruited adults with a formal diagnosis of muscle dysmorphia (MD), a psychological illness defined by preoccupation that one lacks muscularity and/or leanness, combined with significant functional impairment. This study presented descriptive statistics for a range of clinically relevant questionnaires in one of the largest samples of adults with confirmed diagnoses of MD. METHOD: We recruited 29 adults who met diagnostic criteria for MD as determined by semi-structured diagnostic interviews and administered a battery of questionnaires assessing MD symptomology, compulsive exercise, and disordered eating. Descriptive statistics were calculated for both total and subscale scores for each questionnaire. Raincloud plots are included to show the distribution of total scores. RESULTS: Of the 29 participants, 26 completed all questionnaires. Mean scores were high across all questionnaires and broadly consistent with results in past studies that also recruited a clinical MD sample. Most participants scored above proposed clinical cut-off scores for questionnaires assessing compulsive exercise and disordered eating. CONCLUSIONS: This study adds to the small body of published questionnaire data in clinical MD samples. We stress that questionnaire scores should not be used alone to infer the presence of MD, but could be considered as a useful adjunct to a comprehensive clinical interview.

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.

Pilot study of single-dose psilocybin for serotonin reuptake inhibitor-resistant body dysmorphic disorder.

OBJECTIVE: Body dysmorphic disorder (BDD) is an often-severe condition in which individuals are preoccupied by misperceptions of their appearance as defective or ugly. Only serotonin reuptake inhibitors and cognitive-behavioral therapy have been demonstrated efficacious in randomized controlled trials. Psilocybin is a psychedelic drug with growing evidence for safety and efficacy in treatment of depression. This study aimed to pilot test the feasibility, tolerability, safety, and efficacy of psilocybin treatment of adults with BDD. METHODS: In this open-label trial, 12 adults (8 women, 4 men) with moderate-to-severe non-delusional BDD that had been unresponsive to at least one serotonin reuptake inhibitor trial received a single oral dose of psilocybin 25 mg. There was no control group. Psychological support was provided before, during, and after the dosing session. The primary outcome measure for efficacy was the Yale-Brown Obsessive Compulsive Disorder Scale Modified for BDD (BDD-YBOCS) score during 12 weeks of assessments after dosing. RESULTS: All participants completed dosing and all follow-up assessments. BDD-YBOCS scores decreased significantly over 12 weeks of follow-up (p < .001) with a large effect size (partial eta squared = 0.54), and significant changes from baseline were present at week 1 and persisted through week 12. Secondary efficacy measures of BDD symptoms, conviction of belief, negative affect, and disability also improved significantly, and no serious adverse events occurred. At week 12, seven participants (58%) were rated responders, based on ≥30% decrease in BDD-YBOCS. CONCLUSION: This study provides promising preliminary support for psilocybin as a treatment of BDD, warranting future controlled studies.
