---|---|---|---|---|
Primary | EDEQ (Eating Disorder Examination Questionnaire) at 1-10 Weeks and at 1 year | The EDE-Q is a 41-item self-report questionnaire version of the Eating Disorder Examination, which is a semi-structured interview designed to assess eating disorders symptom frequency and severity over the past 28 days. The EDE-Q uses a 7-point forced-choice rating scheme (No days; 1-5 days; 6-12 days; 13-15 days; 16-22 days; 23-27 days; Everyday). The EDE-Q has four subscales with the question stem "How many days out of the past 28 days...": Restraint (e.g. Have you been consciously trying to restrict the amount of food you eat to influence your shape or weight?), Eating Concern (e.g. Have you had a definite fear that you might not be able to either resist eating or stop eating?), Weight Concern (e.g. Has your weight influenced how you think about (judge) yourself as a person?), and Shape Concern (e.g. How dissatisfied have you felt about your shape?). | 1 year and 10 weeks | |
Primary | SUDS (Subjective Units of Distress Scale) at 1-10 Weeks and at 1 year | The SUDS scale is a self-report behavioral measure used during exposure treatment and behavioral assessment to measure anxiety. The SUDS scale has been shown to be a valid and reliable measure of state anxiety. SUDS ratings can range from 0 (completely calm) to 100 (highest anxiety). Other reference points used in this study include 25 (noticeable, but not bothersome anxiety), 50 (bothersome anxiety), and 75 (very bothersome anxiety). Subjective anxiety was assessed both in terms of categorical response and overall change. Categorical response was defined as a drop of at least five points in average SUDS across the exposure across visits. | 1 year and 10 weeks | |
Primary | Body Mass Index (BMI) at 1-10 Weeks and at 1 year | Participants will be weighed at 1-10 Weeks and at 1 year and BMI will be calculated in order to see if the BMI of an individual has changed over time. | 1 year and 10 weeks |
