Body image, emotions and thought control strategies in body dysmorphic disorder compared to eating disorders and healthy controls.

OBJECTIVE A disordered body image, emotions such as shame and disgust, and intrusive thoughts are described as important and interdependent features of body dysmorphic disorder (BDD). However, research in this field is scarce and knowledge is often based on clinical observation. METHODS The present study examined body image dimensions, emotions, and thought control strategies in individuals with: BDD (n=31), anorexia nervosa (n=32), bulimia nervosa (n=34), and healthy controls (n=33). Assessment was based on structured diagnostic interviews and self-report questionnaires. RESULTS Individuals with BDD scored higher on psychosocial and appearance manipulation dimensions of body image compared to healthy controls. Furthermore, they reported higher psychosocial impairment due to appearance than both eating disorder groups. In terms of emotions, BDD subjects reported a higher degree of negative emotions compared to healthy controls, whereas no differences were found in comparison to eating-disordered patients. Individuals with BDD reported using maladaptive strategies such as worrying and confrontation more often than healthy controls, when encountering intrusive and unwanted thoughts. CONCLUSION The results indicate that individuals with BDD experience substantial psychosocial impairment due to appearance, high levels of various negative emotions and frequently use maladaptive thought control strategies.

Classification of body dysmorphic disorder — What is the advantage of the new DSM-5 criteria?

OBJECTIVE In DSM-5 the diagnosis of body dysmorphic disorder (BDD) has been subjected to two important changes: Firstly, BDD has been assigned to the category of obsessive-compulsive and related disorders. Secondly, a new criterion has been defined requiring the presence of repetitive behaviors or mental acts in response to appearance concerns. The aims of this study were to report the prevalence rates of BDD based on a DSM-5 diagnosis, and to evaluate the impact of the recently introduced DSM-5 criteria for BDD by comparing the prevalence rates (DSM-5 vs. DSM-IV) METHODS BDD-criteria (DSM-IV/DSM-5), dysmorphic concerns, and depressive symptoms, were assessed in a representative sample of the German general population (N=2129, aged 18-65years). RESULTS The association between BDD case identification based on DSM-IV and DSM-5 was strong (Phi=.95, p<.001), although point prevalence of BDD according to DSM-5 was slightly lower (2.9%, n=62 vs. 3.2%, n=68). Approximately one third of the identified BDD (DSM-5) cases reported time-consuming behavioral acts in response to appearance concerns. In detail, 0.8% of the German general population fulfilled the BDD criteria and reported repetitive acts of at least one hour/day. CONCLUSIONS The revised criteria of BDD in DSM-5 do not seem to have an impact on prevalence rates. However, the recently added B-criterion reflects more precisely the clinical symptoms of BDD, and may be useful for distinguishing between various severity levels related to repetitive behaviors/mental acts.

Body dysmorphic disorder and nonweight-related body image concerns in individuals with eating disorders

OBJECTIVE Research on the prevalence of body dysmorphic disorder (BDD) in individuals with eating disorders (EDs) is scarce. Nonweight-related appearance concerns, which can be considered as variants of BDD concerns, have also rarely been examined in EDs. This study therefore investigates BDD prevalence and nonweight-related appearance concerns in EDs. METHOD One hundred individuals with EDs (49 inpatients with anorexia nervosa, 51 inpatients with bulimia nervosa) completed structured diagnostic interviews and self-report questionnaires. RESULTS Twelve individuals with EDs (12.0%) suffered from comorbid BDD, with their body dysmorphic concerns being unrelated to weight and shape. BDD lifetime-prevalence was 15.0%. There was a high prevalence of dissatisfaction with nonweight-related body features such as skin, hair, teeth, nose, and height (20.8 to 53.5%). DISCUSSION Findings indicate that BDD is a frequent comorbid disorder in individuals with EDs. Furthermore, along with weight and body shape, nonweight-related appearance concerns are also common in individuals with EDs.

Prevalence of body dysmorphic disorder in a German psychiatric inpatient sample

Body dysmorphic disorder (BDD) is a distressing or impairing preoccupation with an imagined or slight defect in appearance. Only a few studies have examined BDD prevalence in psychiatric settings. Prevalence rates vary widely and most studies have been conducted in outpatient samples. In the current study, we examined 155 adult psychiatric inpatients. Diagnostic criteria of BDD were assessed with the BDD module of the Structured Clinical Interview for DSM-IV. The prevalence of lifetime BDD was 2.6% (95% CI=0.1-5.1%). Currently 1.9% of the patients suffered from BDD (95% CI=0.0-4.0%). None of these patients were diagnosed with BDD on admission or during hospitalization. The BDD rates found in this study are considerably lower than lifetime and current prevalence rates reported by two other studies conducted in adult psychiatric inpatient settings (Grant et al., 2001; Conroy et al., 2008). The differences may be explained by divergent sample compositions and variation in diagnostic measures. The findings of the current study underline the need for further studies examining BDD prevalence in psychiatric settings and suggest using a combination of screening questionnaire and follow-up interview to diagnose BDD.

Personality traits as vulnerability factors in body dysmorphic disorder

Cognitive behavioural models consider certain personality traits to be risk factors for the development of Body Dysmorphic Disorder (BDD). Research on personality traits in BDD is scarce, therefore this study examined perfectionism, aesthetic sensitivity and the behavioural inhibition system (BIS) in BDD. Furthermore, the association between these personality traits and the extent of dysmorphic concerns was investigated. Individuals with BDD (n=58) and a population based control sample (n=2071), selected from a representative German population survey, completed self-report questionnaires assessing DSM-5 criteria of BDD, dysmorphic concerns, perfectionism, aesthetic sensitivity and BIS-reactivity. Individuals with BDD reported significantly higher degrees of perfectionism as well as of BIS-reactivity compared to the population based control sample, whereas the groups did not differ significantly regarding aesthetic sensitivity. However, for the total sample, each of the personality traits was related dimensionally to dysmorphic concerns. Current BDD models consider perfectionism and aesthetic sensitivity to be vulnerability factors. In addition to these concepts, the present study suggests that BIS-reactivity is related to BDD. Self-reported aesthetic sensitivity was not found to be specifically pronounced in BDD, but along with perfectionism and BIS-reactivity aesthetic sensitivity was generally associated with dysmorphic concerns.

Visual selective attention in body dysmorphic disorder, bulimia nervosa and healthy controls

OBJECTIVE Cognitive behavioral models postulate that selective attention plays an important role in the maintenance of body dysmorphic disorder (BDD). It is suggested that individuals with BDD overfocus on perceived defects in their appearance, which may contribute to the excessive preoccupation with their appearance. METHODS The present study used eye tracking to examine visual selective attention in individuals with BDD (n=19), as compared to individuals with bulimia nervosa (BN) (n=21) and healthy controls (HCs) (n=21). Participants completed interviews, questionnaires, rating scales and an eye tracking task: Eye movements were recorded while participants viewed photographs of their own face and attractive as well as unattractive other faces. RESULTS Eye tracking data showed that BDD and BN participants focused less on their self-rated most attractive facial part than HCs. Scanning patterns in own and other faces showed that BDD and BN participants paid as much attention to attractive as to unattractive features in their own face, whereas they focused more on attractive features in attractive other faces. HCs paid more attention to attractive features in their own face and did the same in attractive other faces. CONCLUSION Results indicate an attentional bias in BDD and BN participants manifesting itself in a neglect of positive features compared to HCs. Perceptual retraining may be an important aspect to focus on in therapy in order to overcome the neglect of positive facial aspects. Future research should aim to disentangle attentional processes in BDD by examining the time course of attentional processing.

An app-based blended intervention to reduce body dissatisfaction: A randomized controlled pilot study.

Objective: As a common experience in the general population, dissatisfaction with one’s body is associated with a variety of psychological problems and unhealthy behaviors, including the development of eating disorders. Therefore, the purpose of the present study was to develop and evaluate an app-based intervention to reduce body dissatisfaction. Method: Participants reporting elevated levels of body dissatisfaction were randomly allocated to an app-based intervention (n = 26) or to a wait list group (n = 27). The app-based intervention included a brief counseling session and 14 days of training with the Mindtastic Body Dissatisfaction app (MT-BD). The MT-BD app uses gamification strategies to systematically foster approach of functional and avoidance of dysfunctional stimuli. The primary outcome was body dissatisfaction as assessed with the Body Dissatisfaction scale of the Eating Disorder Inventory-2 (Garner, 1991). Secondary outcome measures included severity of eating disorder symptoms and depressive symptoms. Results: Participants in the intervention group showed significantly greater reductions in body dissatisfaction compared to the wait list group (d = −0.62). The intervention group also showed greater reductions in eating disorder symptoms compared to the wait list group (d = −0.46). Reductions in body dissatisfaction and eating disorder symptoms were sustained at a 1-month follow-up. Conclusion: We found preliminary evidence that an app-based intervention may significantly reduce body dissatisfaction. Further research using larger samples and targeting clinical populations is necessary to evaluate the potential of interventions such as MT-BD.

Approach and avoidance: Relations with the thin body ideal in women with disordered eating behavior

Recent research suggests that automatic cognitive biases are linked to body dissatisfaction and disordered eating behavior. However, little is known about automatic action tendencies in the field of body image research. The aim of the present study was to examine approach and avoidance biases toward the thin body ideal and normal weight bodies and whether these are pronounced in individuals showing disordered eating behavior. Participants were divided into a group with disordered eating behavior (n = 55) and without disordered eating behavior (n = 45). To assess approach and avoidance tendencies, the Approach-Avoidance Task was used during which the participants were instructed to approach or avoid thin and normal weight body pictures. Our results indicated faster push than pull movements towards thin and normal weight body pictures. However, participants with and without disordered eating behavior did not differ with regard to their reactions. Furthermore, we found positive associations between the avoidance of normal weight body pictures and perceived pressure to confirm to media ideals. Future research is warranted to replicate our findings and to extend our knowledge on approach and avoidance biases toward body pictures in patients suffering from eating disorders.

Pavlovian-to-instrumental transfer: A new paradigm to assess pathological mechanisms with regard to the use of Internet applications

HighlightsTheories of addiction stress the role of conditioned cues on instrumental responses.We developed a paradigm with cues related to Internet gaming and Internet shopping.Instrumental responding increased in the presence of conditioned cues.Severity of Internet gaming affected acquisition of the conditioned response.The strength of outcome‐specific expectancies affected the ‘gaming PIT’‐Effect. ABSTRACT At present, there is a considerable lack of human studies that investigated the impact of conditioned cues on instrumental responding although these processes are considered as core mechanisms contributing to the development and maintenance of addictive behaviours. No studies are available that assessed these processes with regard to Internet gaming or Internet shopping applications. We thus developed a Pavlovian‐to‐instrumental transfer (PIT)‐Paradigm implementing appetitive stimuli related to Internet gaming and Internet shopping applications and investigated whether an outcome‐specific PIT‐Effect is observed. In addition, we assessed whether the problematic use of gaming or shopping applications, personality traits and stress would affect the acquisition of knowledge of the experimental contingencies during Pavlovian training and the impact of conditioned stimuli on instrumental responding. A PIT‐Paradigm, screenings for Internet gaming disorder and Internet shopping disorder (s‐IAT), and questionnaires on personality traits (NEO‐FFI, BIS‐15) and perceived stress (PSQ20) were administered to sixty‐six participants. The PIT‐Paradigm demonstrated the effects of stimuli conditioned to rewards related to Internet gaming and Internet shopping applications on instrumental responding to obtain such rewards. Findings also indicated that severity of problematic Internet gaming, but not Internet shopping, contributed to the acquisition of knowledge of the experimental contingencies. Stress, extraversion, neuroticism and gender emerged as further predictors. The strength of expectancy of the different reinforcers affected the ‘gaming PIT’‐Effect; however, none of the variables assessed in the present study showed any effect on the ‘shopping PIT’‐Effect. Future studies including participants with pathological use patterns that can be classified as internet use disorder are warranted to extend these findings.
