Background: When collecting data from human participants, it is often important to minimise the length of questionnaire-based measures. This makes it possible to ensure that the data collection is as engaging as possible, while it also reduces response burden, which may protect data quality. Brevity is especially important when assessing eating disorders and related phenomena, as minimising questions pertaining to shame-ridden, unpleasant experiences may in turn minimise any negative affect experienced whilst responding. Methods: We relied on item response theory to shorten three eating disorder and body dysmorphia measures, while aiming to ensure that the information assessed by the scales remained as close to that assessed by the original scales as possible. We further tested measurement invariance, correlations among different versions of the same scales as well as different measures, and explored additional properties of each scale, including their internal consistency. Additionally, we explored the performance of the 3-item version of the modified Weight Bias Internalisation Scale and compared it to that of the 11-item version of the scale. Results: We introduce a 5-item version of the Eating Disorder Examination Questionnaire, a 3-item version of the SCOFF questionnaire, and a 3-item version of the Dysmorphic Concern Questionnaire. The results revealed that, across a sample of UK adults (N = 987, ages 18–86, M = 45.21), the short scales had a reasonably good fit. Significant positive correlations between the longer and shorter versions of the scales and their significant positive, albeit somewhat weaker correlations to other, related measures support their convergent and discriminant validity. The results followed a similar pattern across the young adult subsample (N = 375, ages 18–39, M = 28.56). Conclusions: These results indicate that the short forms of the tested scales may perform similarly to the full versions. Plain English summary: This manuscript introduces short versions of existing measures of eating disorders and body dysmorphia, specifically the Eating Disorder Examination Questionnaire, the SCOFF Questionnaire, and the Dysmorphic Concern Questionnaire. We further investigate the properties of the recently introduced 3-item short version of the modified Weight Bias Internalisation Scale. Across analyses including measurement invariance testing and bivariate correlations aiming to assess convergent and discriminant validity, we find support that the short scales may perform similarly to their longer versions. These short scales may contribute in meaningful ways to research where the brevity of questionnaire-type measures may make a difference by contributing to data quality. [ABSTRACT FROM AUTHOR]

The Body Image Questionnaire-20 (FKB-20) is one of the most applied self-report measures in the context of body image assessment in German-speaking regions. A version of the FKB-20 capturing an ideal concept of body image is also available. A special property of the scale is its high sensitivity for individuals suffering from anorexia nervosa. The present research provided a short version of this scale (for both variants) and examined its validity in a representative sample (N = 2,347) of the German population. We utilized factor analysis methods to identify the optimal short scale of the measure, finding excellent model fit and reliability for a two-factor model (FKB-6) for both real and ideal body image. Both versions of the FKB-6 can be considered invariant across sex and age groups. Good reliability indices were shown for both versions of the FKB-6. The reliability indices were similar to those mentioned in previous studies. Our study also revealed, that large discrepancies between the real and an ideal body image are correlated with somatic and body dysmorphic symptoms. Finally, we provided norm values for comparisons of individual scores with the general population. The FKB-6 is a valid and a reliable measure that economizes assessments by clinicians and researchers.

Two studies were conducted to assess appearance‐related visual processing mechanisms in populations at risk of disorders characterized by body image disturbance. Using inverted stimuli, Experiment 1 assessed visual processing mechanisms associated with body, face, and house viewing in adolescents. Experiment 2 applied the same protocol to assess appearance‐related configural processing in high‐ and low‐risk adolescent women, and women recovering from disorders characterized by body image disturbance. Experiment 1 found evidence for typical configural face and body processing, although adolescent women reported higher levels of body image concern (BIC) and self‐objectified to a greater extent than adolescent men. In Experiment 2, typical body inversion effects were seen in the low‐risk group, whilst there was some evidence to suggest a disruption to the configural processing of body stimuli in high‐risk adolescents and in women recovering from body image disorders. Women in recovery were also quicker to respond to all stimuli, whilst high‐risk adolescents took longer to respond to bodies than to other stimuli. Configural face processing was intact in all groups, and effects did not directly relate to BIC or self‐objectification. These findings have implications for future research looking to inform early interventions and treatment, suggesting that there could be a tendency to visually process individual body parts at the expense of the whole‐body form in women at risk of developing body image disorders, as well as those in recovery.

Many individuals experience body-size and -shape misperception (BSSM). Body-size overestimation is associated with body dissatisfaction, anxiety, depression, and the development of eating disorders in individuals who desire to be thinner. Similar symptoms have been noted for those who underestimate their muscularity. Conversely, individuals with high body mass indices (BMI) who underestimate their adiposity may not recognize the risks of or seek help for obesity-related medical issues. Although social scientists have examined whether media representations of idealized bodies contribute to the overestimation of fat or underestimation of muscle, other scientists suggest that increases in the prevalence of obesity could explain body-fat underestimation as a form of renormalization. However, these disparate approaches have not advanced our understanding of the perceptual underpinnings of BSSM. Recently, a new unifying account of BSSM has emerged that is based on the long-established phenomenon of visual adaptation, employing psychophysical measurements of perceived size and shape following exposure to "extreme" body stimuli. By inducing BSSM in the laboratory as an aftereffect, this technique is rapidly advancing our understanding of the underlying mental representation of human bodies. This nascent approach provides insight into real-world BSSM and may inform the development of therapeutic and public-health interventions designed to address such perceptual errors.

Given the centrality of body dissatisfaction in the manifestation of eating, exercise, and affective disturbances in men, measurement of this construct becomes essential. Across 2 studies with male undergraduates (Ns = 189 and 188), the psychometric properties, including incremental validity and factor structure, of the 25-item Body Parts Satisfaction Scale for Men (BPSS-M) were examined. Three factors-Upper Body, Legs, and Face-that included items measuring both muscularity and leanness were established. The factors were internally consistent and temporally stable (over 6 months), and support was found for their convergent, discriminant, and concurrent validity. Further, we established that, after controlling for social desirability and drive for muscularity, body satisfaction contributes uniquely to men's experience of disordered eating, negative affect and mood, and psychological well-being. The BPSS-M yielded reliable and valid scores with undergraduate men, suggesting that it may be useful for understanding not only body satisfaction but disordered eating and affective disturbances as well.

Abstract: This study aimed to explore the manifestation of body dysmorphic disorder symptoms in a sample of people with eating disorders and to investigate possible associations between body dysmorphia and alexithymia. Forty patients currently seeking treatment for an eating disorder completed a battery of six measures assessing alexithymia, mood, eating behaviours, weight-related body image, body dysmorphia and non-weight related body image. Significant moderate positive correlations (Pearson''s r) between selected variables were found, suggesting that participants with high levels of dysmorphic concern (imagined ugliness) have more difficulty with the affective elements of alexithymia, that is, identifying and describing feelings. When depression, eating attitudes, and weight-related body image concerns were controlled for, significant moderate positive correlations between this alexithymia factor and dysmorphic concerns remained present. An independent-samples t-test between eating-disordered participants with and without symptoms of body dysmorphic disorder (BDD) revealed significant group differences in difficulties identifying feelings. This pattern of results was replicated when the groups were identified on the basis of dysmorphic concerns, as opposed to BDD symptoms. This study highlights the associations between alexithymia and body dysmorphia that have not previously been demonstrated. [Copyright &y& Elsevier]

Abstract: Existing research argues that the muscular male body ideal, often promoted in the media, is associated with male body dissatisfaction and increasingly problematic attempts to attain unrealistic body shape by young males. The present study sought to examine the influence of “lad magazines”, a highly popular media sector over the last decade, and also the role of dating, or relationship, status, on the association between internalization of appearance ideals and drive for muscularity. One hundred and Sixty-one males between the ages of 18 and 36 from a UK university completed measures of exposure to lad magazines, eating disturbance, sociocultural attitudes towards appearance, and drive for muscularity. Internalization of appearance ideals was found to be a possible mediator of the relationship between lad magazine exposure and both drive for muscularity and eating disturbance. These effects were significantly stronger among non-dating males, suggesting that, especially for single men, preoccupation with attaining the ideal male body may be enhanced by the use of media that promote traditional masculine ideals.

Over the past two decades, there has been a change in the way men think about their bodies. The media portrays images of men with muscular bodies and a "six pack" abdomen. These images can create body dissatisfaction in males. With the change in the way that the media and society in the United States look at men, so has the drive for men to achieve this ideal body image. Eating disorders, body dysmorphia, and strict exercise and diet regimens seem to plague young men as do the images in advertisements. Although eating disorders in men are similar to what women experience, men seem to strive for more body mass whereas women try to obtain thinness. Gay men and heterosexual men seem to experience eating disorders in the same way although there are differences between how they perceive their bodies. This paper outline show the media contributes to body dissatisfaction in men. In addition to understanding how the media affects men, it is important to review and possibly revise out understanding of eating disorders and body dysmorphia symptoms to gain a solid understanding of how these symptoms appear in men today.
