RESUMO

OBJECTIVE: Abnormal visual processing has been proposed as a mechanism underlying excessive focus on minor appearance flaws in body dysmorphic disorder (BDD). Existing BDD research has not differentiated the various stages of face processing (featural, first-order configural, holistic and second-order configural) that are required for higher-order processes such as emotion recognition. This study investigated a hierarchical visual processing model to examine the nature of abnormalities in face processing in BDD. METHOD: Thirty BDD participants and 27 healthy controls completed the Navon task, a featural and configural face processing task and a facial emotion labelling task. RESULTS: BDD participants performed similarly to controls when processing global and local non-face stimuli on the Navon task, when detecting subtle changes in the features and spacing of a target face, and when labelling emotional faces. However, BDD participants displayed poorer performance when viewing inverted faces, indicating difficulties in configural processing. CONCLUSIONS: The findings only partially support prior work. However, synthesis of results with previous findings indicates that heterogenous task methodologies may contribute to inconsistent findings. Recommendations are provided regarding the task parameters that appear most sensitive to abnormalities in BDD.

RESUMO

Invasive and noninvasive neurostimulation therapies for obsessive-compulsive and related disorders (OCRD) were systematically reviewed with the aim of assessing clinical characteristics, methodologies, neuroanatomical substrates, and varied stimulation parameters. Previous reviews have focused on a narrow scope, statistical rather than clinical significance, grouped together heterogenous protocols, and proposed inconclusive outcomes and directions. Herein, a comprehensive and transdiagnostic evaluation of all clinically relevant determinants is presented with translational clinical recommendations and novel response rates. Electroconvulsive therapy (ECT) studies were limited in number and quality but demonstrated greater efficacy than previously identified. Targeting the pre-SMA/SMA is recommended for transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS). TMS yielded superior outcomes, although polarity findings were conflicting, and refinement of frontal/cognitive control protocols may optimize outcomes. For both techniques, standardization of polarity, more treatment sessions (>20), and targeting multiple structures are encouraged. A deep brain stimulation (DBS) 'sweet spot' of the striatum for OCD was proposed, and CBT is strongly encouraged. Tourette's patients showed less variance and reliance on treatment optimization. Several DBS targets achieved consistent, rapid, and sustained clinical response. Analysis of fiber connectivity, as opposed to precise neural regions, should be implemented for target selection. Standardization of protocols is necessary to achieve translational outcomes.

RESUMO

BACKGROUND AND OBJECTIVES: Previous research has indicated that body dysmorphic disorder (BDD) and obsessive-compulsive disorder (OCD) often demonstrate similar cognitive impairments across multiple domains. However, findings for both disorders have not consistently shown impaired cognition. As such, BDD and OCD might share an overlapping pattern of cognitive heterogeneity, characterised by subgroups with different cognitive profiles. METHODS: To evaluate this possibility, we compared 26 BDD, 24 OCD, and 26 healthy control participants on a comprehensive eight-domain cognitive battery. Then, cluster analysis was performed on the BDD and OCD participants' combined data to explore for cognitive subgroups. RESULTS: No significant differences were found between the three groups' cognitive functioning, except for poorer visual learning in OCD relative to healthy controls. Cluster analysis produced two cognitive subgroups within the combined BDD and OCD data, characterised by intact cognition (52%) and broadly impaired cognition (48%). Each subgroup comprised both BDD and OCD participants, in similar proportions. The subgroups did not differ in clinical or demographic features. LIMITATIONS: Sample sizes were moderate. Future research should investigate clustering patterns both in larger groups and separately in BDD and OCD samples to determine replicability. CONCLUSIONS: These findings suggest that BDD and OCD may involve similar patterns of cognitive heterogeneity, and further imply that individuals with either disorder can show a wide range of cognitive profiles, thus necessitating a nuanced approach to future cognitive research in BDD and OCD.

RESUMO

BACKGROUND: The popularity of videoconferencing platforms has skyrocketed during the COVID-19 pandemic; however, concerns have been expressed regarding the potential for video calls to promote appearance dissatisfaction because individuals are exposed to an image of themselves on camera for extended periods. OBJECTIVES: The aim of the current study was to characterize current video usage behaviors and their relation to appearance dissatisfaction and interest in aesthetic procedures in the general population. METHODS: An online survey was completed by 335 adults currently living in Australia. Multiple aspects of video usage were assessed, including engagement in video-manipulation techniques to enhance appearance and the focus of visual attention (ie, on self or others) while on video calls. The Dysmorphic Concern Questionnaire was administered to determine if video-use behaviors were associated with greater body image disturbance. RESULTS: Over one-third of participants had identified new appearance concerns while on video. Dysmorphic concern was associated with self-focused attention, greater engagement in video-manipulation behaviors, and increasing appearance concerns due to their time on video calls. Individuals who identified new video-based appearance concerns reported greater interest in obtaining future beauty treatments (eg, waxing) and aesthetic procedures (eg, nonsurgical procedures such as antiwrinkle injections). CONCLUSIONS: This is one of first empirical studies to report the potential consequences of video-call usage for increasing appearance dissatisfaction and dysmorphic concern, and to demonstrate a link between the use of video calls and interest in cosmetic procedures.

RESUMO

BACKGROUND: Childhood maltreatment and trauma may be risk factors for the development of body dysmorphic disorder (BDD). However, the limited research to date on these topics has been constrained by either the absence of a matched healthy control group or non-comprehensive assessments. METHODS: This study assessed the prevalence and severity of childhood maltreatment and other traumatic events in 52 BDD participants (56% female) and 57 matched controls (51% female) with no history of mental illness, using the Childhood Trauma Questionnaire and a checklist assessing broader traumatic events. RESULTS: In comparison with controls, participants with BDD showed a higher prevalence of emotional abuse (61.5% vs. 33.3%) and physical neglect (59.6% vs. 28.1%), as well as more severe overall maltreatment, emotional abuse, and emotional and physical neglect. BDD participants were also more likely to meet cut-offs for multiple types of maltreatment and reported an elevated number and variety of broader traumatic childhood events (e.g., life-threatening illness). In BDD, increasingly severe maltreatment was correlated with greater severity of BDD symptoms, anxiety and suicidal ideation. CONCLUSIONS: These data suggest that childhood maltreatment and exposure to other traumatic events are common and severe in BDD and are cross-sectionally associated with the severity of clinical symptoms. Adversity linked to maladaptive family functioning during childhood may therefore be especially relevant to people with BDD and could relate to social and emotional processing problems in the disorder.

RESUMO

OBJECTIVES: Body dysmorphic disorder is commonly considered a contraindication for major cosmetic surgery, but whether body dysmorphic disorder relates to poorer outcomes from minor cosmetic treatment remains unknown. This study aimed to explore the prevalence of body dysmorphic disorder in clients seeking non-surgical cosmetic procedures and to examine whether body dysmorphic disorder clients are vulnerable in minor cosmetic settings. Vulnerability was explored in terms of psychological distress, unrealistic expectations and motivations for treatment outcome, and reduced satisfaction with past cosmetic procedures. METHOD: A cross-sectional online survey was completed by 154 women seeking minor cosmetic procedures which included the Body Dysmorphic Disorder Questionnaire - Dermatology Version to screen for body dysmorphic disorder, and measures of cosmetic treatment motivation, expectations and satisfaction. RESULTS: Roughly 25% of women in the current sample screened positive for a potential body dysmorphic disorder diagnosis. Participants with suspected body dysmorphic disorder demonstrated higher levels of psychological distress and more unrealistic expectations and motivations for cosmetic treatment, such as improving social or romantic relationships. However, body dysmorphic disorder participants reported similar levels of satisfaction with past minor cosmetic treatments to the non-body dysmorphic disorder group. CONCLUSION: While the relationship between body dysmorphic disorder and treatment outcome warrants further investigation in prospective research tracking satisfaction and adverse reactions over time, this preliminary evidence suggests clients with suspected body dysmorphic disorder display several vulnerabilities in non-surgical cosmetic settings. Given the rapidly increasing accessibility of minor cosmetic procedures, further research is needed to determine their safety for clients with body dysmorphic disorder. Detection of body dysmorphic disorder in non-surgical cosmetic settings could facilitate earlier psychological intervention, promoting superior long-term outcomes.

RESUMO

OBJECTIVE: Current understanding of cognitive functioning in body dysmorphic disorder is limited, owing to few studies, small sample sizes and assessment across only limited cognitive domains. Existing research has also shown inconsistent findings, with both intact and impaired cognition reported in body dysmorphic disorder, which might point towards cognitive heterogeneity in the disorder. This study aimed to examine the cognitive profile of body dysmorphic disorder in a large sample across eight cognitive domains, and to explore whether cognitive subgroups might be identified within body dysmorphic disorder. METHOD: Cognitive domains of inhibition/flexibility, working memory, speed of processing, reasoning and problem-solving, visual and verbal learning, attention/vigilance and social cognition were assessed and compared between 65 body dysmorphic disorder patients and 70 healthy controls. Then, hierarchical clustering analysis was conducted on the body dysmorphic disorder group's cognitive data. RESULTS: Group-average comparisons demonstrated significantly poorer cognitive functioning in body dysmorphic disorder than healthy controls in all domains except for attention/vigilance and social cognition. Cluster analysis identified two divergent cognitive subgroups within our body dysmorphic disorder cohort characterised by (1) broadly intact cognitive function with mild selective impairments (72.3%), and (2) broadly impaired cognitive function (27.7%). However, the clusters did not significantly differ on clinical parameters or most sociodemographic characteristics. CONCLUSION: Our findings demonstrate considerable cognitive heterogeneity among persons with body dysmorphic disorder, rather than uniform deficits. Poor performances in the broadly impaired subgroup may have driven group-level differences. However, our findings also suggest a dissociation between cognitive functioning and clinical characteristics in body dysmorphic disorder that has implications for current aetiological models. Additional research is needed to clarify why some people with body dysmorphic disorder demonstrate cognitive deficits while others do not.

RESUMO

Objective: To develop and validate a novel patient-reported measure to assess internally and externally driven expectations for change after a cosmetic procedure, termed the aesthetic procedure expectations (ASPECT) scale. Method: In total, 186 adults recruited from nonsurgical cosmetic clinics in Melbourne, Australia, accessed an online survey (150 completed; 81% response rate) including the novel ASPECT questionnaire, demographics, and measures of psychological distress. Results: The final sample included 141 women and 5 men with a mean age of 44.78 years (standard deviation = 11.68) with <10% missing data. Results supported a two-factor ASPECT scale measuring intrinsic and extrinsic expectations, with high internal consistency and convergent validity. Heightened extrinsic and intrinsic expectations were both associated with individuals who were emotionally distressed, younger, and had previously undertaken more cosmetic procedures. Cutoff scores for the ASPECT subscales are proposed to aid cosmetic practitioners in identifying clients requiring further assessment. Conclusions: The ASPECT scale may provide a reliable and useful clinical tool for cosmetic practitioners to assess unrealistic expectations and determine which clients may require more in-depth consultation before undergoing surgical or nonsurgical cosmetic treatment.

RESUMO

There has not been a comprehensive comparison of differences between men and women with body dysmorphic disorder (BDD) for approximately two decades. Major social and technological changes over this time may have changed patterns of bodily concerns and symptom profile among men and women with BDD, thus warranting an updated assessment of gender differences. BDD symptomatology, insight, and associated clinical and sociodemographic characteristics were compared between 49 women and 27 men with BDD. Skin was the most common concern for both men and women. Women showed more concerns than men about the appearance of their legs. Men were more concerned about muscularity/body build. Women demonstrated significantly more severe distress associated with BDD behaviours, and poorer illness insight than men. Age at BDD onset, illness duration, as well as mean severity of depression, anxiety, stress, and social anxiety were similar across the genders. These data suggest that the most common body areas of concern in people with BDD have not dramatically changed over the past two decades. However, the finding of worse insight among women is novel, and suggests a need for further investigation.

RESUMO

OBJECTIVE: During the COVID-19 pandemic, Australia implemented widespread closure of beauty and cosmetic services to control the virus spread. The effect of these restrictions is unknown, given that beauty services are widely used for stress relief or to enhance confidence. The current study explored the relationship between engagement in appearance-focused behaviors and distress regarding beauty service closure. Participants with high and low levels of dysmorphic concern were compared to determine whether COVID-19 restrictions may affect these groups differently. METHOD: An online survey was completed by 216 participants living in Australia. Questions addressed engagement in appearance-focused behaviors during the COVID-19 pandemic and attitudes toward beauty service closure. The Dysmorphic Concern Questionnaire (DCQ) was used to group participants by low and high dysmorphic concern. RESULTS: Appearance-focused behaviors decreased in the low DCQ group (n = 163) during the COVID-19 pandemic, while such behaviors in the high DCQ group (n = 53) remained unchanged. Individuals who were living alone, younger, reported higher dysmorphic concern and greater distress over beauty service closure engaged in more frequent appearance-focused behaviors (R2 = .57, p < .001). The high DCQ group reported greater distress over beauty service closure and increased desire to obtain future beauty treatments. DISCUSSION: While COVID-19 restrictions may have provided a break from societal appearance pressure for those with low dysmorphic concern, appearance-focused behaviors persisted in individuals with high dysmorphic concern. A greater understanding of the long-term impacts on appearance-related distress is needed to determine mental health priorities emerging from the COVID-19 pandemic.
