Description of Study Measures

Instrument	Construct Assessed	Cronbach’s α	Number of Items	Answer Responses	Scoring Method
Eating Disorders Examination Questionnaire, 6th edition
Restraint	Attempts to restrict food intake for long periods (≥8 hours) over the past month	0.84	5	7-point scale Number of days categorized as: 0=none, 1=1–5 days 2=6–12 days 3=13–15 days 4=16–22 days, 5=23–27 days 6=28 days]or “Not at all” to “A lot”	Scale scores are average of item scores. Global EDE-Q score is sum of scale scores. Higher scale scores indicate greater eating disorder risk.
Eating Concerns	Preoccupation with and feelings towards eating food over the past month	0.79	5
Weight Concerns	Feelings toward one’s weight over the past month	0.85	5
Shape Concerns	Feelings about one’s body shape over the past month	0.90	8
Global EDE-Q	Overall eating disorder behaviors and cognitions over the past month	n/a
Three Factor Eating Questionnaire-18
Emotional Eating	Influence of emotions on the urge to eat	0.84	3	4-point Likert scale: Definitely false to Definitely true	Scale scores are average of item scores. Higher scale scores indicate greater emotional eating or a greater loss of control over eating.
Disinhibited Eating	Uncontrolled eating behaviors	0.74	3a
Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ)
Pressures from Media	Perceived pressure from the media	0.88	4b	5-point Likert scale: Strongly disagree to Strongly agree	Scale scores are average of item scores. Higher scores indicate greater feelings of pressure to obtain the physical appearance standard set by the media, greater awareness of societal appearance norms set by the media, and/or more frequent comparisons of one’s body to people in the media.
Information from Media	Awareness of societal appearance norms conveyed by the media	0.87	4b
Internalization of Media	Influence of generic media (e.g., TV, magazines)	n/a	1b
Body Checking Questionnaire	Frequency of pinching areas of the body to see how much fat there is		1	6-point scale: Never to Always	Scale scores are average of item scores. Higher scores indicate greater body checking and avoidance.
Body Image and Avoidance Questionnaire	Frequency of avoiding wearing clothes that make one particularly aware of the shape of their body	0.72	1
Body Image Distortion	Distorted view of body size	n/a	1	Perceived body weight: very thin/thin=1, average=2, slightly heavy/overweight=3. Actual body weight: underweight [BMI<18.5]=1, normal weight [BMI=18.5–24.9]=2, overweight [BMI>25]=3.	Perceived body weight score minus actual body weight category. Means closer to 0 indicate body weight is perceived accurately.
Appearance Schema Inventory-Revised
Self-Evaluative Salience	How one defines or measure themselves and their self- worth by their physical appearance	0.84	8c	5-point Likert scale: Strongly disagree to Strongly agree	Scale scores are average of item scores.

Patient Health Questionnaire-8	Depression severity over the last 2 weeks	0.86	8	4-point scale (Not at all to Nearly every day)	Higher scores indicate greater depression severity.

^aThe original Disinhibited Eating scale was reduced to minimize participant burden by selecting items with the strongest factor loadings (Karlsson, et al., 2000).

^bSATAQ scales were condensed to focus on the currently used media forms and by using items with highest factor loadings (Thompson, et al., 2004).

^cAppearance Schema Inventory-Revised scales were shortened to reduce repetition and participant burden.

^dScale was reduced to include items with highest factor loadings (Martin-Albo, Nunez, Navarro, & Grijalvo, 2007).
