Gazing rituals in body dysmorphic disorder.

BACKGROUND AND OBJECTIVES: Gazing rituals and selective attention to perceived flaws during gazing are considered as maintaining factors in cognitive-behavioral models for body dysmorphic disorder (BDD). This study investigated different durations of BDD-like gazing at different facial stimuli (an unfamiliar face, the participant's own face, and the participant's own reflection in the mirror) with regard to effects on dissociation, attractiveness evaluations and perceptual uncertainty. The aim of this study was to examine the hypothesized causal effects of gazing rituals on appearance preoccupation. METHODS: We asked 115 females to complete a face gazing paradigm with three different facial stimuli and, depending on the condition, different gazing durations. We also examined the influence of BDD symptom severity on the reactions to different facial stimuli. RESULTS: Five minutes of gazing significantly increased dissociation. Participants rated the attractiveness of self-relevant stimuli, especially the own photographed face, below average and lower than the unfamiliar face. LIMITATIONS: Limitations with regard to sample characteristics and experimental design are discussed. CONCLUSIONS: Our findings support cognitive-behavioral models for BDD and indicate that therapists may extend therapeutic interventions like mirror retraining by specific perceptual retraining with photographs of the patients.

Gazing at facial features increases dissociation and decreases attractiveness ratings in non-clinical females - A potential explanation for a common ritual in body dysmorphic disorder.

Rituals, such as gazing at faces, are common in body dysmorphic disorder (BDD) and appear in cognitive-behavioral models as a maintaining factor. Rituals are also common in obsessive-compulsive disorder (OCD). In contrast to OCD, the proposed associations between rituals and intrusive thoughts/appearance preoccupation have not been empirically investigated for BDD. We examined if the assumed effect of gazing rituals on attractiveness ratings exists and if it is associated with dissociation. In an experiment, we asked N = 65 non-clinical females to focus on the nose of a photographed face at pre- and post-test. In between, participants gazed at the nose of either the same (relevant gazing) or another face (irrelevant gazing). We found increasing dissociation after gazing in both conditions and a differentially stronger decrease of attractiveness ratings in the relevant gazing condition. Our findings support the hypothesized effect of gazing rituals on attractiveness evaluation in cognitive-behavioral models for BDD.

Prevalence of body dysmorphic disorder and associated features in German adolescents: A self-report survey.

Prior research has not yet investigated the prevalence of body dysmorphic disorder (BDD) in adolescents and young adults based on criteria from the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). In the current study, the point prevalence of BDD, comorbid symptoms, and associated features, such as appearance-related suicidality, level of insight or history of plastic surgeries, were examined in a non-clinical sample of German adolescents and young adults (n=308), between 15 and 21 years old, using self-report measures. Eleven participants (3.6%; 95% CI=[1.9, 5.8]) met DSM-5 criteria for BDD. Self-reported BDD (vs. no-BDD) was related to respondents showing significantly more obsessive-compulsive (OC) symptoms and lower degrees of insight regarding appearance concerns. Significantly more adolescents and young adults with vs. without self-reported BDD (36.4% vs. 8.8%) reported appearance-related suicidal ideation. In conclusion, body dysmorphic symptoms are common in adolescents and young adults and are associated with high rates of comorbid symptoms and suicidal ideation.

Effects of mood induction on consumers with vs. without compulsive buying propensity: an experimental study.

Compulsive buying (CB) is excessive and leads to impairment and distress. Several studies aimed to explore the phenomenology and antecedents of CB, especially affective states. However, these studies mostly used retrospective self-report and mostly focused on compulsive buyers only. Therefore, this study aims to directly compare consumers with CB propensity and controls on experimental proxies of buying behavior and to investigate 1) effects of neutral vs. negative mood inductions and 2) whether mood effects on buying behavior are specific to CB. Forty female consumers with CB propensity and 40 female controls were randomly assigned to a neutral or negative mood induction. Buying related behavior (likelihood to expose oneself to a shopping situation, urge and probability to buy, willingness to pay) was assessed. Consumers with CB propensity differed from controls in all buying behavior aspects except for willingness to pay. Neither main effects of mood nor group×mood interaction effects on buying behavior were found. However, consumers with CB propensity were emotionally more strongly affected by a negative mood induction. Although negative affect has previously been reported to precede buying episodes in CB, our findings do not indicate specific negative mood effects on buying, neither in CB nor in controls.
