Appearance Dissatisfaction and Body Dysmorphic Disorder in the Dermatology Patient.

Dermatologists routinely see patients with inflammatory skin conditions and aesthetic concerns that involve substantial psychological comorbidity. However, most dermatologists do not receive formal training in this area, and many are unsure how to best help treat certain patients holistically. Body dysmorphic disorder (BDD) is a common and distressing psychiatric condition that disproportionately impacts dermatology patients, including patients living with chronic inflammatory skin conditions such as acne and atopic dermatitis. BDD is characterized by preoccupation with nonexistent or minimally noticeable flaws in physical appearance that cause clinically significant distress or impairment in functioning. Adolescent populations may be particularly vulnerable to clinically significant body image dissatisfaction, including BDD, due to the high prevalence of acne and the pervasive role of social media platforms. The rise of social media may exacerbate body image issues through repetitive exposure to idealized and often unrealistic beauty standards. Though screening questionnaires can assist dermatologists in recognizing BDD, dermatologists must collaborate with mental health providers to provide comprehensive care to vulnerable patients, including adolescents.J Drugs Dermatol. 2024;23(7):545-550.  doi:10.36849/JDD.8156.

Learning of the same task subserved by substantially different mechanisms between patients with body dysmorphic disorder and healthy individuals.

It has remained unclear whether individuals with psychiatric disorders involving altered visual processing employ similar neuronal mechanisms during perceptual learning of a visual task. We investigated this question by training patients with body dysmorphic disorder, a psychiatric disorder characterized by distressing or impairing preoccupation with nonexistent or slight defects in one's physical appearance, and healthy controls on a visual detection task for human faces with low spatial frequency components. Brain activation during task performance was measured with functional magnetic resonance imaging before the beginning and after the end of behavioral training. Both groups of participants improved performance on the trained task to a similar extent. However, neuronal changes in the fusiform face area were substantially different between groups such that activation for low spatial frequency faces in the right fusiform face area increased after training in body dysmorphic disorder patients but decreased in controls. Moreover, functional connectivity between left and right fusiform face area decreased after training in patients but increased in controls. Our results indicate that neuronal mechanisms involved in perceptual learning of a face detection task differ fundamentally between body dysmorphic disorder patients and controls. Such different neuronal mechanisms in body dysmorphic disorder patients might reflect the brain's adaptations to altered functions imposed by the psychiatric disorder.

Clinical characteristics among sexual minority and heterosexual women with body dysmorphic disorder.

Body dysmorphic disorder (BDD) is a common disorder associated with substantial comorbidity, impairment, and poor quality of life. Research on subcultural variations of BDD is limited but may impact assessment and treatment of the disorder. The current study examined clinical features in a sample of sexual minority (SM; n = 43) and heterosexual (n = 155) women with diagnosed BDD. Participants completed self-report and clinician-administered measures of demographic and clinical characteristics. Results indicated largely similar clinical features across groups with some exceptions: compared to non-SM women, SM women were younger (M = 25.50 vs 31.96 years, p < .001), had better BDD-related insight (M = 14.51 vs 16.26, p = .01), endorsed a greater number of disliked body parts, and were more likely to express preoccupation with body build (OR = 4.6, 95% CI [2.0, 10.9]), chin/jaw (OR = 4.7, 95% CI [2.1, 10.3]), and shoulders (OR = 10.1, 95% CI [2.7, 37.9]), possibly reflecting nuanced beauty ideals within the SM community. There were no significant group differences in other body parts of concern, BDD severity, or depression. Future studies are needed in larger, more inclusive samples to explore the relationship between diverse identities on BDD and its associated features.

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.

Surgery in octogenarians with intracranial meningiomas improves functional outcome at 1 year.

PURPOSE: The population is aging, and age remains an important factor in deciding surgical candidacy for intracranial tumors. The natural history and surgical behavior of meningiomas in octogenarians are not well understood. We evaluated the surgical and functional outcomes, including survival, among octogenarians with intracranial meningiomas in a single institution. METHODS: The Tumor Registry (2004-2021) was used to identify octogenarian patients (ages 80-89) diagnosed with intracranial meningioma. Primary endpoints were 1-year survival and functional outcome measured with mRS postsurgery. Kaplan-Meier, univariable Log-rank tests, and multivariable Cox hazards proportional regression models were used for assessing factors associated with overall survival (OS) in octogenarians with meningiomas who underwent surgery; logistic regression and McNemar's were used to further characterize risk factors affecting functional surgical outcome at 1 year. RESULTS: Thirty octogenarians with intracranial meningioma who underwent surgery were identified. Median age was 82.5 years and 66.6% were female patients. The 1-year median postsurgical survival probability for all octogenarians with meningioma was 86.3% and no intraoperative mortality was observed. Frailty (mFI-5, p = 0.84), tumor grade (p = 0.11), tumor size (p = 0.22), extent of resection (p = 0.35), and Karnofsky scale on admission (p = 0.93) did not significantly affect the survival in octogenarians with meningiomas which were treated surgically. The 1-year postoperative functional status of octogenarian meningioma patients who underwent surgery was significantly improved compared to pre-op mRS (McNemar's chi-squared = 9.6, df = 1, p-value = 0.001946). CONCLUSION: In octogenarians with meningiomas, surgical intervention significantly improves the pre-operative modified Rankin Scale at 1 year postsurgery in this cohort.

Dermatology in Contemporary Times: Building Awareness of Social Media's Association With Adolescent Skin Disease and Mental Health.

BACKGROUND: The contribution of psychological disorders to the burden of skin disease has been poorly explored in adolescent patients. The review aims to provide insights into the psychological, social, occupational, and social medias' association with acne, atopic dermatitis (AD), and aesthetics in adolescent patients. METHODS: The project used a modified Delphi process comprising face-to-face discussions followed up online.  The systematic literature search results informed the 14 draft statements. During an expert panel meeting, the draft statements underwent the panel's evaluation at a workshop, followed by a plenary discussion adopting five statements using evidence from the literature coupled with the panel's opinions and experiences.  Results: Studies reported an association between poor sleep, social impairment, and mental health disorders, including body dysmorphic disorder (BDD) with acne or AD in adolescents with acne or AD. Education for patients and parents may improve self-management skills and self-responsibility, promoting better outcomes for acne and AD. The use of certain types of social media can contribute to unrealistic expectations regarding the outcomes of cosmetic procedures. Social media use may also be associated with, and potentially contribute to unrealistic appearance expectations and certain mental health conditions. However, social media use may have benefits, such as connection, diversity, social support, increased self-esteem, safe identity experimentation, and an increased opportunity for self-disclosure.  Conclusions: The association with negative life events, BDD, suicidal ideation, depression, and anxiety are thought to be high for adolescent patients with acne or AD. Using social media for information has both positive and negative aspects. Awareness of the risks and benefits of receiving health information about dermatological disease among adolescents needs to be improved through the education of patients and clinicians. Action-oriented items need to be developed to help dermatologists address these issues in clinical practice.Rieder EA, Andriessen A, Cutler V, et al. Dermatology in contemporary times: building awareness of social media's association with adolescent skin disease and mental health. J Drugs Dermatol. 2023;22(8):817-825. doi:10.36849/JDD.7596.

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.

Mechanisms of cognitive-behavioral therapy effects on symptoms of body dysmorphic disorder: a network intervention analysis.

BACKGROUND: Body dysmorphic disorder (BDD) is a severe and undertreated condition. Although cognitive-behavioral therapy (CBT) is the first-line psychosocial treatment for this common disorder, how the intervention works is insufficiently understood. Specific pathways have been hypothesized, but only one small study has examined the precise nature of treatment effects of CBT, and no prior study has examined the effects of supportive psychotherapy (SPT). METHODS: This study re-examined a large trial (n = 120) comparing CBT to SPT for BDD. Network intervention analyses were used to explore symptom-level data across time. We computed mixed graphical models at multiple time points to examine relative differences in direct and indirect effects of the two interventions. RESULTS: In the resulting networks, CBT and SPT appeared to differentially target certain symptoms. The largest differences included CBT increasing efforts to disengage from and restructure unhelpful thoughts and resist BDD rituals, while SPT was directly related to improvement in BDD-related insight. Additionally, the time course of differences aligned with the intended targets of CBT; cognitive effects emerged first and behavioral effects second, paralleling cognitive restructuring in earlier sessions and the emphasis on exposure and ritual prevention in later sessions. Differences in favor of CBT were most consistent for behavioral targets. CONCLUSIONS: CBT and SPT primarily affected different symptoms. To improve patient care, the field needs a better understanding of how and when BDD treatments and treatment components succeed. Considering patient experiences at the symptom level and over time can aid in refining or reorganizing treatments to better fit patient needs.

Predictors of extended length of stay related to craniotomy for tumor resection.

Background: Hospital length of stay (LOS) related to craniotomy for tumor resection (CTR) is a marker of neurosurgical quality of care. Limiting LOS benefits both patients and hospitals. This study examined which factors contribute to extended LOS (eLOS) at our academic center. Methods: Retrospective medical record review of 139 consecutive CTRs performed between July 2020 and July 2021. Univariate and multivariable analyses determined which factors were associated with an eLOS (≥8 days). Results: Median LOS was 6 days (IQR 3-9 days). Fifty-one subjects (36.7%) experienced an eLOS. Upon univariate analysis, potentially modifiable factors associated with eLOS included days to occupational therapy (OT), physical therapy (PT), and case management clearance (p < .001); and discharge disposition (p < .001). Multivariable analysis revealed that pre-operative anti-coagulant use (OR 10.74, 95% CI 2.64-43.63, p = .001), Medicare (OR 4.80, 95% CI 1.07-21.52, p = .04), ED admission (OR 26.21, 95% CI 5.17-132.99, p < .001), transfer to another service post-surgery (OR 30.00, 95% CI 1.56-577.35, p = .02), and time to post-operative imaging (OR 2.91, 95% CI 1.27-6.65, p = .01) were associated with eLOS. Extended LOS was not significantly associated with ED visits (p = .45) or unplanned readmissions within 30 days of surgery (p = .35), and both (p = .04; p = .04) were less likely following a short LOS (<5 days). Conclusion: While some factors driving LOS related to CTR are uncontrollable, expedient pre- and post-operative management may reduce LOS without compromising care.

Octogenarian Brain Tumor Registry: Single-Institution Surgical Outcomes and Mortality Study.

BACKGROUND: Surgical intervention for brain tumor patients aged 80 to 89 years is controversial, as the comorbidities and physiology associated with aging are often thought to increase surgical risks. Surgical outcomes, however, are not well characterized for octogenarians. This review therefore assessed the outcomes and mortality risk associated with tumor removal in octogenarians at our academic institution. METHODS: Retrospective review of patients aged 80 to 89 who underwent craniotomy for tumor resection (CTR) at our institution between 2004-2021 and who were diagnosed with meningioma, glioblastoma, or metastatic disease. Primary outcome was 30-day mortality. RESULTS: Sixty-one CTRs were included in analysis. Median age was 83 (interquartile range 81-85) years, and the most common preoperative comorbidity was hypertension (n=44). Most patients (n=35) had a preoperative modified Rankin Scale (mRS) score between 0-2. Seventeen (27.9%) patients experienced postoperative complications (i.e., urinary tract infection, deep venous thrombosis, etc.), and 26.2% (n=16) experienced new-onset neurologic deficits postoperatively (i.e., aphasia, motor deficits, etc.). Upon discharge, most patients (n=43) had an mRS score of 3-4. Within 30 days of surgery, 14.8% (n=9) of patients were readmitted to the hospital and 8.2% (n=5) of patients died: 2 with meningioma, 1 with glioblastoma, and 2 with metastatic disease. The most common cause of death was intracranial hemorrhage (n=3). Three-month mortality was 23.0% (n=14). Mean survival after surgery was 33 months for meningioma patients, 6.9 months for glioblastoma patients, and 15 months for patients with metastatic lesions. CONCLUSION: Our review found a 30-day mortality rate of 8.2% across all tumor types, and mean survival was similar to that previously reported for patients across all age groups. Surgical intervention for octogenarian tumor patients is therefore feasible, safe, and likely worthwhile for extending and improving lives.

Targeting Accuracy of the Leksell Vantage Stereotactic System for Deep Brain Stimulation Surgery: A Retrospective Review.

BACKGROUND: Compared with the Leksell G frame, the new Leksell Vantage stereotactic headframe offers many benefits during deep brain stimulation (DBS) procedures. OBJECTIVE: To define the "real-world" targeting accuracy of the Vantage frame for performing DBS lead implants. METHODS: Retrospective review of all patients who underwent DBS using the Vantage frame with our surgeon between July 2021 and May 2022. Target and actual coordinates of implanted DBS leads were determined in BrainLab. RESULTS: Thirty-three electrode trajectories (17 left-sided, 16 right-sided) were included. On the right, actual electrode placement was, on average, 0.95 mm more medial, 1.06 mm more posterior, and 0.55 mm more superior compared with planned trajectories. The vector error was 1.93 ± 0.91 mm. On the left, actual electrode placement was 0.49 mm more lateral, 0.66 mm more posterior, and 0.67 mm more superior than planned trajectories. The vector error was 1.68 ± 0.66 mm. After excluding all electrodes that were repositioned after microelectrode recording and/or test stimulation, right-sided electrodes (n = 10) were 0.88 mm more medial, 0.94 mm more posterior, and 0.76 mm more superior than planned trajectories. The vector error was 1.74 ± 1.01 mm. Left-sided electrodes (n = 14) were 0.49 mm more lateral, 0.63 mm more posterior, and 0.49 mm more superior than planned trajectories. The vector error was 1.62 ± 0.68 mm. CONCLUSION: This study demonstrated the accuracy of the Leksell Vantage frame in comparison with the traditional Leksell G frame.

Complications Related to Deep Brain Stimulation Lead Implantation: A Single-Surgeon Case Series.

BACKGROUND: Deep brain stimulation (DBS) is the mainstay of surgical treatment for movement disorders, yet previous studies have shown widely varying complication rates. Given the elective nature of DBS surgery, minimizing surgical complications is imperative. OBJECTIVE: To evaluate short-term and long-term complications related to DBS lead implantation surgeries performed by an experienced surgeon and provide an updated benchmark comparison for other DBS centers and alternative therapies. METHODS: A retrospective chart review of patients who underwent DBS lead implantation surgery by a single surgeon at our institution between 2012 and 2020 was conducted. Demographic and clinical data including surgical complications were collected. A Kaplan-Meier survival analysis was used to evaluate the cumulative risk of lead revision or removal over time. Associations between patient characteristics and various complications were evaluated. RESULTS: Four hundred fifty-one DBS leads were placed in 255 patients. Thirteen leads and 11 patients required revision. In total, 3.6% (95% CI [1.3%-5.9%]) of patients required revision at 1 year and 4.8% (95% CI [1.9%-7.6%]) at 5 years, with per-lead revision rates of 2.3% (95% CI [0.9%-3.6%]) and 3.3% (95% CI [1.5%-5.1%]), respectively. Less common diagnoses such as Tourette syndrome, post-traumatic tremor, and cluster headache trended toward association with lead revision or removal. CONCLUSION: DBS performed by an experienced surgeon is associated with extremely low complication rates.

Mechanisms of cognitive behavioral therapy vs. supportive psychotherapy in body dysmorphic disorder: An exploratory mediation analysis.

Body dysmorphic disorder (BDD) is common, severe, and often chronic. Cognitive behavioral therapy (CBT) is the first-line psychosocial treatment for BDD, with well-established efficacy. However, some patients do not improve with CBT, and little is known about how CBT confers its effects. Neurocognitive processes have been implicated in the etiology and maintenance of BDD and are targeted by CBT-BDD treatment components. Yet, the malleability of these factors in BDD, and their potential role in mediating symptom improvement, are not well understood. Understanding how treatment works could help optimize treatment outcomes. In this secondary data analysis of a randomized clinical trial of CBT vs. supportive psychotherapy (SPT) in BDD (n = 120), we examined whether treatment-related changes in detail processing (Rey-Osterrieth Complex Figure test), maladaptive appearance beliefs (Appearance Schemas Inventory-Revised), and emotion recognition (Emotion Recognition Task) mediated treatment outcome. All constructs improved over time and were associated with symptom improvement. CBT was associated with greater improvements in maladaptive beliefs than SPT. None of the variables examined mediated symptom improvement. Findings suggest that with successful treatment, individuals with BDD demonstrate reduced neurocognitive deficits (detail processing, emotion recognition, maladaptive beliefs) and that CBT is more likely than SPT to improve maladaptive appearance beliefs. More work is needed to understand mechanisms of change and thus maximize treatment outcomes.

Predictors of pharmacotherapy outcomes for body dysmorphic disorder: a machine learning approach.

BACKGROUND: Serotonin-reuptake inhibitors (SRIs) are first-line pharmacotherapy for the treatment of body dysmorphic disorder (BDD), a common and severe disorder. However, prior research has not focused on or identified definitive predictors of SRI treatment outcomes. Leveraging precision medicine techniques such as machine learning can facilitate the prediction of treatment outcomes. METHODS: The study used 10-fold cross-validation support vector machine (SVM) learning models to predict three treatment outcomes (i.e. response, partial remission, and full remission) for 97 patients with BDD receiving up to 14-weeks of open-label treatment with the SRI escitalopram. SVM models used baseline clinical and demographic variables as predictors. Feature importance analyses complemented traditional SVM modeling to identify which variables most successfully predicted treatment response. RESULTS: SVM models indicated acceptable classification performance for predicting treatment response with an area under the curve (AUC) of 0.77 (sensitivity = 0.77 and specificity = 0.63), partial remission with an AUC of 0.75 (sensitivity = 0.67 and specificity = 0.73), and full remission with an AUC of 0.79 (sensitivity = 0.70 and specificity = 0.79). Feature importance analyses supported constructs such as better quality of life and less severe depression, general psychopathology symptoms, and hopelessness as more predictive of better treatment outcome; demographic variables were least predictive. CONCLUSIONS: The current study is the first to demonstrate that machine learning algorithms can successfully predict treatment outcomes for pharmacotherapy for BDD. Consistent with precision medicine initiatives in psychiatry, the current study provides a foundation for personalized pharmacotherapy strategies for patients with BDD.

Credibility and expectancy of smartphone-based cognitive behavioral therapy among adults with body dysmorphic disorder.

BACKGROUND: Few patients receive cognitive behavioral therapy, the gold-standard for body dysmorphic disorder (CBT-BDD). Smartphones can make evidence-based interventions, like CBT-BDD, more accessible and scalable. A key question is: how do patients view it? Low credibility and expectancy would likely translate to low uptake and engagement outside of research settings, diminishing the impact. Thus, it is important to understand patients' beliefs about digital CBT-BDD. METHODS: We compared credibility and expectancy in a coach-guided app-based CBT-BDD trial (N=75) to a previous in-person CBT-BDD trial (N = 55). We further examined the relationship of perceptions of digital CBT-BDD to baseline clinical and demographic factors and dropout. RESULTS: Credibility did not differ between the in-person (M=19.3) and digital (M=18.3) trials, p=.24. Expectancy for improvement was moderately higher for in-person (M=58.4) than digital (M=48.3) treatment, p=.005. In the digital trial, no demographic variables were associated with credibility or expectancy. Better BDD-related insight and past non-CBT BDD therapy were associated with greater expectancy. Credibility was associated with lower likelihood of dropout. DISCUSSION: Digital CBT-BDD was regarded as similarly credible to in-person CBT-BDD but with lower expectancy. Tailored expectancy-enhancing strategies could strengthen this novel approach, particularly among those with poorer insight and without prior BDD treatment.

Learning of the same task subserved by substantially different mechanisms between patients with Body Dysmorphic Disorder and healthy individuals.

It is generally believed that learning of a perceptual task involving low-level neuronal mechanisms is similar between individuals. However, it is unclear whether this assumption also applies to individuals with psychiatric disorders that are known to have altered brain activation during visual processing. We investigated this question in patients with body dysmorphic disorder (BDD), a psychiatric disorder characterized by distressing or impairing preoccupation with nonexistent or slight defects in one's physical appearance, and in healthy controls. Participants completed six training sessions on separate days on a visual detection task for human faces with low spatial frequency (LSF) components. Brain activation during task performance was measured with functional magnetic resonance imaging (fMRI) on separate days prior to and after training. The behavioral results showed that both groups of participants improved on the visual detection task to a similar extent through training. Despite this similarity in behavioral improvement, neuronal changes in the Fusiform Face Area (FFA), a core cortical region involved in face processing, with training were substantially different between groups. First, activation in the right FFA for LSF faces relative to High Spatial Frequency (HSF) faces that were used as an untrained control increased after training in BDD patients but decreased in controls. Second, resting state functional connectivity between left and right FFAs decreased after training in BDD patients but increased in controls. Contrary to the assumption that learning of a perceptual task is subserved by the same neuronal mechanisms across individuals, our results indicate that the neuronal mechanisms involved in learning of a face detection task differ fundamentally between patients with BDD and healthy individuals. The involvement of different neuronal mechanisms for learning of even simple perceptual tasks in patients with BDD might reflect the brain's adaptations to altered functions imposed by the psychiatric disorder.

Early response to cognitive behavioral therapy for body dysmorphic disorder as a predictor of outcomes.

Individuals with body dysmorphic disorder (BDD) suffer from distressing or impairing preoccupations with perceived imperfections in their appearance. This often-chronic condition is associated with significant functional impairment and elevated rates of psychiatric comorbidity and morbidity, including depression, substance use disorders, and suicidality. Cognitive behavioral therapy (CBT) for BDD has been shown to be efficacious. However, this intervention is long (up to 24 weeks) relative to many manualized approaches for other related conditions, there is a significant shortage of clinicians trained in CBT for BDD, and some patients drop out of treatment and/or do not respond. Thus, there is great interest in understanding and predicting who is most likely to respond, to better allocate clinical resources. This secondary data analysis of participants enrolled in prior uncontrolled and controlled studies of CBT for BDD explored whether early response to CBT, operationalized as percentage change in symptom severity within the first four weeks and the first 12 weeks of this 24-week treatment, predicts clinical outcomes for patients with BDD (n = 90). The findings indicated that minimal early symptom change was not indicative of eventual non-response. This suggests that patients and clinicians should not be discouraged by limited early improvement but should instead continue with a full course of treatment before reevaluating progress and alternative interventions. Overall, the results support the view that treatment success is more likely if a longer CBT protocol is followed. More work is needed to understand mechanisms of change and thus match optimal interventions to patient characteristics.

An Evaluation of the Body Dysmorphic Disorder Symptom Scale as a Measure of Treatment Response and Remission in Psychotherapy and Medication Trials.

The Body Dysmorphic Disorder Symptom Scale (BDD-SS) is a self-report tool that captures an array of representative behavioral and cognitive symptoms commonly displayed by individuals with BDD. The BDD-SS is regularly used among experts in the field, though its utility as a measure of treatment response has not yet been formally evaluated. Results from two clinical trials of BDD treatment were pooled from an archived database to create a sample of 220 BDD participants who received either psychosocial or medication-based interventions for BDD. We used baseline BDD-SS scores to describe psychometric properties, baseline correlations with other scales to examine the content validity of the BDD-SS, and longitudinal symptom data to evaluate capacity to detect clinically relevant change. Results indicated that the BDD-SS has good psychometric properties and is able to detect symptom change over time, although it showed lower rates of reliable change with treatment relative to the gold standard rater-administered Yale-Brown Obsessive-Compulsive Scale Modified for BDD (BDD-YBOCS). The BDD-SS offers meaningful information about treatment response in a self-report format and may be particularly useful to employ in clinical practice settings as a means of gathering symptom and treatment response data via self-report when rater-administered interviews are not feasible, although it may underestimate the extent of improvement with treatment.

Knowledge and competency standards for specialized cognitive behavior therapy for adult obsessive-compulsive disorder.

Obsessive-Compulsive Disorder (OCD) is a leading cause of disability world-wide (World Health Organization, 2008). Treatment of OCD is a specialized field whose aim is recovery from illness for as many patients as possible. The evidence-based psychotherapeutic treatment for OCD is specialized cognitive behavior therapy (CBT, NICE, 2005, Koran and Simpson, 2013). However, these treatments are not accessible to many sufferers around the world. Currently available guidelines for care are deemed to be essential but insufficient because of highly variable clinician knowledge and competencies specific to OCD. The phase two mandate of the 14 nation International OCD Accreditation Task Force (ATF) created by the Canadian Institute for Obsessive Compulsive Disorders is development of knowledge and competency standards for specialized treatments for OCD through the lifespan deemed by experts to be foundational to transformative change in this field. This paper presents knowledge and competency standards for specialized CBT for adult OCD developed to inform, advance, and offer a model for clinical practice and training for OCD. During upcoming ATF phases three and four criteria and processes for training in specialized treatments for OCD through the lifespan for certification (individuals) and accreditation (sites) will be developed based on the ATF standards.
