A Multimethod Analysis of Incompleteness and Visual "Not Just Right" Experiences in Body Dysmorphic Disorder

Updating theoretical frameworks in body dysmorphic disorder: A systematic review and meta-analysis

Background

Real world studies and psychological literature often do not consolidate existing data with theoretical models on body dysmorphic disorder (BDD).

Objective

This systematic review aims to refine and empirically support the conceptual understanding of BDD through an updated theoretical framework.

Methods

We systematically searched PubMed, Embase, CENTRAL, Scopus, and Web of Science from database inception to 26 November 2023 for studies reporting factors predisposing or associated with a diagnostic and statistical manual of mental disorders IV/V confirmed diagnosis of BDD. Data analysis was performed qualitatively or via random effects meta-analysis, followed by a critical appraisal and integration with existing theories.

Results

Twenty four studies comprising 961 BDD patients and 230,076 healthy controls were analyzed. Marriage is a protective factor (pooled risk ratio 0.67, P = .004) not well-explored in current literature. Factors including teasing, physical and sexual abuse, higher explicit beliefs about attractiveness, lower self-esteem, psychological conditions were not pooled due to heterogeneity. These findings are consistent with cognitive behavioral models of BDD and were integrated to create an updated theoretical framework, while highlighting evidence gaps.

Conclusion

Understanding and recognizing patients with BDD is important as successful therapies need to correct the underlying psychological component. Further research should explore relationships between cognitive and behavioral aspects of BDD.

The relationship between sensory phenomena and interoception across the obsessive-compulsive spectrum: a systematic review

BACKGROUND

Uncomfortable sensations preceding repetitive behaviours, known as sensory phenomena, have been documented across the obsessive-compulsive spectrum. Indirect evidence suggests altered interoception may play a role in these shared experiences of sensory phenomena; however, research explicitly measuring this relationship is limited. The current systematic review aimed to establish the nature of sensory phenomena and interoception in obsessive-compulsive and related disorders (OCRDs) and tic disorders as potential maintaining factors of these disorders.

METHODS

PsycINFO, PubMed, and Scopus databases were searched from 2007 to April 2024, yielding 65 studies.

RESULTS

While the majority of studies presented low risk of bias, significant overlap and ambiguity characterised the measurement and conceptualisation of sensory phenomena and interoception. Overall, higher sensory phenomena was associated with greater symptom severity in several obsessive-compulsive spectrum disorders. Obsessive-compulsive disorder and tic disorder samples were characterised by lower interoceptive accuracy, with mixed findings on interoceptive sensibility. Some limited research emerged suggesting altered interoceptive abilities may be associated with greater sensory phenomena in obsessive-compulsive disorder and tic disorders.

CONCLUSIONS

Sensory phenomena are experienced across the obsessive-compulsive spectrum. Future research should explore interoceptive abilities across the OCRDs, and build upon evidence supporting a relationship between sensory phenomena and interoception in OCD and tic disorders.

The effects of body dysmorphic disorder on women's quality of life and body image at difference stages of pregnancy

BACKGROUND

Pregnancy is a time of great change for women, both mentally and physically. For any pregnant woman, this time of change can be difficult as the woman needs to constantly adapt to the rapidly changing body. This change could be especially challenging for a woman who has previously struggled with symptoms of body dysmorphic disorder (BDD), which cause individuals to perceive part(s) of their body as particularly ugly or deformed, creating distress that affects several areas of functioning. These distorted perceptions have been associated with low self-reported functioning in physical and psychological areas. The present study assessed the effects of BDD symptoms on the physical and psychological functioning of pregnant women at different points throughout their pregnancy.

METHODS

During July 2021 through April 2022, one hundred and fifty-eight women were recruited from various mothers' Facebook groups, women's centers across a city in Southern Texas, and through Prolific. The sample consisted of women in their first, second and third trimesters, as well as women three months postpartum. Information about the presence of BDD symptoms, quality of life, and body image was collected.

RESULTS

We found that women in their second trimester possess the highest quality of life compared to women in their first trimester, third trimester or postpartum. Women with high BDD symptoms have lower quality of life and lower body image compared to women with low BDD, especially for those in their first or third trimesters.

CONCLUSIONS

These findings illustrate the necessity of targeted interventions and support for pregnant women, especially those with BDD symptoms, in order to promote their well-being throughout pregnancy and postpartum.

A comparison of 'not just right experiences' in obsessive-compulsive disorder, anxiety and depressive disorders and non-clinical controls in China

OBJECTIVE

The aim of this study is to investigate the characteristics of 'not just right experiences' (NJREs) in patients with obsessive-compulsive disorder (OCD), anxiety disorders (ADs) or major depressive disorder (MDD), compared with those of healthy controls (HCs).

METHOD

One hundred adults with OCD, 86 adults with ADs, 57 adults with MDD and 60 HCs were enrolled in the study. The Not Just Right Experiences Questionnaire Revised (NJRE-QR), Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) were used to evaluate clinical symptoms in patients with OCD, ADs or MDD. The Obsessive Belief Questionnaire-44 (OBQ-44) was used to evaluate OC beliefs in the OCD patients. The HCs only received assessment using the NJRE-QR. Analysis of variance (ANOVA) and covariance (ANCOVA) were performed to compare the NJREs scores across the groups, while Pearson correlation and partial correlation analyses were used to examine the association between NJREs and other clinical features. The contribution of NJREs to predict OC symptoms was determined by multiple stratified linear regression.

RESULTS

Individuals with OCD had significantly higher scores for the number of NJREs than ADs, but not MDD. The severity of NJREs was also significantly higher in patients with OCD than those with MDD or ADs (F = 5.23 and F = 19.79, respectively, P < 0.01). All the clinical scores in the NJRE-QR were significantly higher than those in the HC group. The number and severity of NJREs correlated significantly with the Y-BOCS total score (r = 0.29 and r = 0.39, respectively, P < 0.01). NJREs showed an independent contribution to OC symptoms, which alone explained 8% of the variation (F = 16.49, ΔR2  = 0.08; P < 0.01).

CONCLUSION

NJREs are related closely to OC symptoms, with their severity discriminating between OCD patients and those with ADs or MDD. NJREs were more specific for OCD in the Chinese population and are therefore worthy of further study in the future.

Reliability and Validity of the Self-Report Version of the Yale-Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder

Despite its frequent use in research studies, the self-report version of the Yale-Brown Obsessive-Compulsive Scale modified for Body Dysmorphic Disorder (BDD-YBOCS-SR) is yet to be formally validated. The present investigation sought to examine the psychometric properties of the BDD-YBOCS-SR across three different samples. In Study 1 (N = 847), we sought to explore the factor structure of the BDD-YBOCS-SR. In addition, we evaluated the convergent and divergent validity with similar self-report measures. In Study 2 (N = 187), the convergence of the BDD-YBOCS-SR with reactivity to an in vivo appearance-related task was observed. In Study 3, we compared scores on the BDD-YBOCS-SR between a clinical sample of individuals with BDD (n = 50) and a "healthy" control sample (n = 51). We further observed the BDD-YBOCS-SR's sensitivity to treatment and convergence with the rater-administered version in the clinical sample. The BDD-YBOCS-SR demonstrated strong psychometric properties across all three studies. Scores on the BDD-YBOCS-SR were found to be strongly associated with appearance anxiety, reactivity to the appearance task, and the rater-administered BDD-YBOCS. The present investigation provides support for the BDD-YBOCS-SR's utility in measuring body dysmorphic symptom severity for use in research and clinical settings.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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