Design outcomes

| Measure | Time frame |
|---|---|
| The first main transdiagnostic ED mechanism investigated in this study is change in PTSD complaints in the EMDR phase compared to the baseline and TAU phase. Symptom severity of PTSD complaints will be measured with the PTSD Checklist for DSM-5 (PCL-5). The Dutch version of the PCL-5 (Boeschoten et al., 2014) is a self-report questionnaire with 20 items, which measures the 20 symptoms of PTSD according to the DSM-5. The transdiagnostic factors of ED decreasing self-reported negative body perception, recovery of the injured self-image and clinical perfectionism will be measured with the EDI-3. The Eating Disorder Inventory-3 (EDI-3; Van Strien, 2014) is a 91-item self-report questionnaire that measures psychological and behavioral characteristics associated with anorexia nervosa and bulimia nervosa. The EDI-3 consists of 12 scales: : pursuit of thinness, bulimia, body dissatisfaction, low self-esteem, personal alienation, interpersonal insecurity, interpersonal alienation, interoceptive problems, emotional dysregulation, perfectionism, asceticism, and fear of adulthood.These 12 scales are subdivided into 5 composite scales: Eating Disorder Risk, Ineffectiveness, Interpersonal Problems, Affective Problems and Overcontrol. The low self-esteem scale is used in this study to measure the transdiagnostic factor injured self-image and the perfectionism scale to measure the transdiagnostic factor perfectionism. The degree of self-reported negative body perception is measured with the body dissatisfaction scale of the EDI-3 and the total score of the Body Attitude Test (BAT; Dutch version, Lichaams Attitude Vragenlijst). The BAT was developed by Probst, Van Coppenolle and Vandereycken (1995); it is a self-report instrument intended to measure subjective body experience and attitude toward one*s body. It differentiates between clinical and non-clinical individuals and between patients with anorexia nervosa versus patients with bulimia nervosa. It is | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary study parameters are changes in the transdiagnostic factors which are positively associated with reduction in ED symptoms: fears related to food, weight and appearance, urge-driven behaviours related to food, such as binge eating, fasting or compensatory behaviours (hyperactivity, vomiting, laxatives) and associated with an increase in Body Mass Index (BMI) after the onset of EMDR therapy comparing to baseline and TAU phase. The ED symptoms will be assessed every two weeks over a baseline period, during TAU, during EMDR and after the interventions with the EDI-3 subscales *pursuit of thinness* and *Bulimia* and by calculating the BMI (weight/height2) of the participants. | — |
