BACKGROUND: Internet-based cognitive behavioral therapy (CBT) and stand-alone mindfulness meditation interventions are gaining empirical support for a wide variety of mental health conditions. In this study, we test the efficacy of web-based therapist-guided mindfulness-based cognitive behavioral therapy (CBT-M) for body dysmorphic disorder (BDD), a psychiatric disorder characterized by preoccupations with perceived defects in appearance.
OBJECTIVE: This study aims to determine whether CBT-M for BDD delivered on the web is feasible and acceptable and whether mindfulness meditation adds to CBT treatment effects for BDD.
METHODS: In this 8-week, 2-arm, parallel pilot randomized controlled trial, n=28 adults (aged between 18 and 55 years) were randomly allocated to an experimental group (web-based therapist-guided CBT-M) or a control group (web-based therapist-guided CBT). Study retention, accrual, and intervention adherence were assessed, along with self-report measures for BDD, depression, anxiety, and pain intensity taken at baseline and postintervention.
RESULTS: This study was feasible to implement and deemed acceptable by participants. After 8 weeks, significant improvements were found on all outcome measures for both treatment groups, and large between-group effect sizes favoring CBT-M were found for BDD symptom severity (d=-0.96), depression (d=-1.06), pain severity (d=-1.12), and pain interference (d=-1.28). However, linear mixed models demonstrated no significant differences between the groups over 8 weeks.
CONCLUSIONS: The results suggest that mindfulness meditation may add to beneficial web-based CBT treatment effects for BDD. An adequately powered randomized control trial of web-based CBT-M is warranted.

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 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.

OBJECTIVE: 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.

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.
CONCLUSIONS: 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.

Mindfulness-based cognitive therapy (MBCT) is garnering increasing empirical interest as an intervention for Body Dysmorphic Disorder (BDD), although no studies of mindfulness as a standalone treatment have included a sample composed entirely of patients with BDD or a comparison group. The aim of this study was to investigate the improvement of MBCT intervention on the core symptoms, emotional dysfunction, and executive function of BDD patients, as well as the feasibility and acceptability of MBCT training.
Patients with BDD were randomized into an 8-week MBCT group (n = 58) or treatment-as-usual (TAU) control group (n = 58) and were assessed at pre-treatment, post-treatment, and 3-month follow-up.
Participants who received MBCT showed greater improvement on self-reported and clinician ratings of BDD symptoms, self-reported emotion dysregulation symptoms and executive function compared with TAU participants. Improvement for executive function tasks was partially supported. In addition, feasibility and acceptability of MBCT training were positive.
There is no systematic assessment of the severity of key potential outcome variables associated with BDD.
MBCT may be a useful intervention for patients with BDD, improving patients\' BDD symptoms, emotion dysregulation, and executive functioning.

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.
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.
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.
This study provides promising preliminary support for psilocybin as a treatment of BDD, warranting future controlled studies.

Dysfunctional cognitive processes and maladaptive interpersonal patterns have been postulated to maintain body dysmorphic disorder (BDD). The present trial evaluated CT for BDD (CT-BDD), which includes modules targeting maladaptive cognitive processing in BDD, as well as elements of schema therapy related to interpersonal problems. We investigated whether (a) CT-BDD is effective, as compared with a wait-list (WL) group at Week 12; (b) outcome of CT-BDD is maintained at posttreatment and 3- and 6-months follow-up; and (c) whether changes in shame and insight mediate changes in BDD symptom severity. Forty adults with BDD were randomized to 36 weeks immediate CT-BDD (n = 21), or to 12-week WL (n = 19). At Week 12, immediate CT-BDD was significantly superior to WL in clinician-rated BDD symptom severity, insight, self-reported BDD symptoms, shame, depression, general symptomatology, and life satisfaction. Changes in outcomes were associated with moderate to large effect sizes at Week 12. Reductions in shame and increase in insight separately mediated changes in BDD symptom severity during treatment at Week 12. From baseline to posttreatment, significant improvements occurred within CT-BDD in clinician-rated symptom severity, insight, depression, global functioning, self-reported BDD symptoms, shame, depression, general symptomatology, and life satisfaction. At posttreatment, improvements were associated with large effect sizes and were maintained at 3- and 6-month follow-up. Preliminary results support the efficacy of CT-BDD. Addressing interpersonal problems in addition to cognitive dysfunctions may increase the benefit of CBT for BDD patients.

Shame is considered central in body dysmorphic disorder (BDD) and empirical accounts highlight the link between shame and BDD symptoms as well as common negative psychosocial effects of the disorder, yet there is a lack of interventions addressing shame in this context. In the past decade, Acceptance and commitment therapy (ACT) and interventions that foster self-compassion have shown promise for reducing the negative effects of shame in a range of clinical problems. The aim of the present study was to develop and evaluate an acceptance and compassion-based treatment specifically targeting shame in BDD. Using a randomized nonconcurrent multiple baseline design, the 12-session intervention, ACT with Compassion (ACTwC), was examined in a psychiatric outpatient sample of five adults diagnosed with BDD. The daily ratings showed marked reductions in BDD-behaviors and self-criticism at posttreatment for four of five participants, while three participants demonstrated decreases in body shame compared to baseline. Improvements were maintained at 6-months follow-up. The intervention also led to reliable long-term improvements in general shame, overall BDD-symptoms, depressive symptoms, and quality of life for four of five participants. All treatment responders showed significant gains in psychological flexibility and self-compassion. Participants reported high credibility and satisfaction with the treatment. These preliminary results suggest that ACTwC may be a promising approach to treating shame in BDD, worthy of further investigation.

Previous findings from cross-sectional studies suggest that social anxiety symptoms and negative peers\' experiences regarding appearance were predictors of body dysmorphic symptoms through appearance-based rejection sensitivity. However, little is known about longitudinal relations and parental appearance rejection on body dysmorphic symptoms. Therefore, this study aims to examine the longitudinal mediation of appearance-based rejection sensitivity with social anxiety symptoms, remembered peers\', maternal, and paternal appearance-based rejection as predictors, and body dysmorphic symptoms as an outcome. The study included 277 university students who completed questionnaires in two-measurements points 5 months apart. The results indicated that social anxiety symptoms predicted changes in body dysmorphic symptoms through appearance-based rejection sensitivity. In addition, remembered childhood peers\' appearance-based rejection predicted both directly and indirectly changes in body dysmorphic symptoms over time. Maternal and paternal appearance-based rejection were not predictors of appearance-based rejection sensitivity or body dysmorphic symptoms. Findings support rejection sensitivity theory and the long-lasting impact of negative peers\' experiences for impaired body dysmorphic symptoms. However, further research regarding remembered parental negative experiences is needed.
