Significant results are printed in bold. Body image was assessed via the Body Image Assessment Scale-Body Dimensions (BIAS-BD; Gardner et al., 2009) for body dissatisfaction and body size distortion, the Eating Disorder Inventory-2 (EDI-2; Garner, 1991; German version by Thiel et al., 1997) for body dissatisfaction, and the Multidimensional Body-Self Relations Questionnaire-Appearance Scales (MBSRQ-AS; Cash et al., 1986; German version by Vossbeck-Elsebusch et al., 2014) for body dissatisfaction, body satisfaction, and self-classified weight.
