115 Dialectical behavior therapy and cognitive behavior therapy in individuals with binge eating disorder: what works for whom? 5 shape influenced how you feel about (judge, think, evaluate) yourself as a person?’) and overvaluation of weight: (i.e.: ‘Over the past 4 weeks has your weight influenced how you feel about (judge, think, evaluate) yourself as a person?’). Following Kenny & Carter (2018), we constructed a composite score of the two overvaluation items by averaging the scores (ranging from 0, ‘no days’, to 6 ‘every day’), with higher scores indicating greater severity. Internal consistency in the current sample was good (Cronbach’s alpha = .928). Concern about shape and weight Concerns about shape were measured using 7 items of the 8-item EDE-Q subscale Shape Concern. Concerns about weight were assessed with 4 items of the 5-item EDE-Q subscale Weight Concern. Because ‘overvaluation of shape and weight’ is a central concept in the CBT-model (Fairburn, 2008) and considered distinct from other body image constructs like shape and weight concerns (Grilo et al., 2013; Masheb et al., 2006; Wade et al., 2011) both scale scores were calculated without the respective overvaluation items. Items on the EDE-Q subscales are answered over the past 28 days, on a 7-point Likert scale with scores ranging from 0 (‘no days’) to 6 (‘every day’). Subscale-scores are calculated by summing the individual item-scores divided by the number of subscale-items. Higher scores indicate greater severity. The EDE-Q has good psychometric properties (Aardoom et al., 2012; Berg et al., 2012). Internal consistency in the current sample was acceptable for shape concern and questionable for weight concern without the overvaluation items (Cronbach’s alphas = .764 and .618 respectively). Dietary restraint The intention to limit food intake / dietary restraint was assessed with the 5-item EDE-Q subscale Restraint. Internal consistency in the current sample was adequate (α = .715). Self-esteem The subscale Low Self-Esteem (LSE: 6 items) of the Eating Disorder Inventory (EDI-3: Garner & Van Strien, 2015) was used to assess self-esteem. Items on the EDI-3 are answered on a 6-point Likert scale (ranging from ‘never’ to ‘always’), and are scored from 0 to 4 (0-0-1-23-4). Subscale scores are calculated by summing the individual item-scores. Higher scores indicate lower self-esteem. The EDI-3 has good psychometric properties and can be used in eating disorder patients (Clausen et al., 2011; Lehmann et al., 2013; Segura-Garcia et al., 2015). In the current study, the LSE-subscale demonstrated good internal consistency (α = .876). Difficulties in emotion regulation The 8-item subscale Emotional Dysregulation of the EDI-3 was used to measure the tendency toward poor impulse regulation and mood intolerance. Higher scores indicate more dysregulation in emotion. Internal consistency in the current sample
