Risks and benefits of social media trends: The influence of "fitspiration", "body positivity", and text-based "body neutrality" on body dissatisfaction and affect in women with and without eating disorders.

This online experimental study investigates the effects of the social media trends "fitspiration" (images of thin-muscular women promoting health and fitness), "body positivity" (images of larger female bodies motivating women to love their bodies), and "body neutrality" (illustrations encouraging women to appreciate the body's functions) on body dissatisfaction and affect in women with and without eating disorders (ED). Women with (n = 172) and women without ED (n = 210) were randomly assigned to the conditions "fitspiration", "body positivity", and text-based "body neutrality", each comprising the presentation of 30 Instagram posts. Before and after viewing the posts, participants answered state questionnaires on body dissatisfaction and affect. The results revealed that body dissatisfaction increased after viewing "fitspiration" images and decreased after viewing "body positivity" and text-based "body neutrality" posts. Positive affect decreased following exposure to "fitspiration" and text-based "body neutrality" but remained unchanged following "body positivity". Negative affect decreased following "body positivity" and text-based "body neutrality" content but did not change following exposure to "fitspiration". There was no differential effect on women with versus without ED. This study demonstrates harmful effects of "fitspiration" on body image and affect, indicating the need for prevention programs for both women with and without ED.

Is my body better than yours? Validation of the German version of the Upward and Downward Physical Appearance Comparison Scales in individuals with and without eating disorders.

Introduction: This study examines the psychometric properties of a German version of the Upward and Downward Physical Appearance Comparison Scales (UPACS and DACS). Methods: A total of 2,114 participants, consisting of 1,360 women without eating disorders (M age = 25.73, SD age = 6.84), 304 men without eating disorders (M age = 24.48, SD age = 6.34), and 450 women with eating disorders (M age = 27.11, SD age = 7.21), completed the UPACS and DACS as well as further questionnaires on appearance comparisons, eating disorder pathology, and self-esteem. Results: Structural equation modeling confirmed the proposed one-factor structure of the original English-language version of the DACS but not of the UPACS. Both scales showed good internal consistency and test-retest reliability. The UPACS and DACS showed the expected correlations with related constructs, indicating acceptable construct validity, with some limitations for women with eating disorders. Discussion: Overall, this study indicates that the German versions of the UPACS and DACS are psychometrically suitable for assessing upward and downward physical appearance comparisons in women and men without eating disorders and women with eating disorders in research and clinical practice.
