Brief summary
The goal of this clinical trial is to develop and test a new internet delivered treatment for adult patients with eating disorders, focused on developing normalized eating patterns and emotion regulation skills. The main focus is to investigate the additional effect of emotion regulation interventions, beyond the effect of other central tratment components normally included in evidence based eating disorder treatment. The internet delivered treatment is divided into two phases, phase A and phase B. Phase A focus on establishing normalised eating patterns, and in phase B the emotion regulation interventions are added. Participants will get access to treatment modules every third day over a time period of 8.5 weeks, each module consist of psychopedagogical material, excercises and home work. Data will be collected via the online research platform every third day during the treatment. Data is also collected at more comprehensive assessment points pre-treatment, post-treatment, and follow up 3 months after end of treatment.
Detailed description
This study uses an experimental single-case design, specifically a randomized replicated AB design. The baseline lenght (i.e., phase A) is randomized for each participant. There is six possible assignments, as the randomization is restricted to give all participants minimum 8 and maximum 12 treatment modules in each phase, with minimum 9 and maximum 14 baseline assessment points.
Interventions
Emotion regulation intervention in two phases. Phase A focus on establishing normalised eating patterns, and in phase B the emotion regulation interventions are added. Participants will get access to treatment modules every third day over a time period of 8.5 weeks, each module consist of psychopedagogical material, excercises and home work.

Study design
Intervention model description
A single-case experimental randomized AB-design. Baseline length (i.e., phase A) and start of the B-phase is randomized for each participant. Both phases consist of active treatment, with the purpose of investigating if the interventions added in phase B could enhance treatment results additionally beyond the interventions given during the baseline period.

Total score range from 36-180. |
| Difficulties in Emotion Regulation Scale, 16 items | Counted from treatment start: at day 1, 4, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60 | Assessment of emotion regulation difficulties, short version. 16 items scored 1-5. Higher scores indicates more difficulties. Total score range from 16-80. |
| The Positive and Negative Affect Schedule, short form | Counted from treatment start: at day 1, 4, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60 | Assessment of affect levels. In this study, only the subscale measuring negative affect is used. 5 items scored 1-5. Higher scores indicate higher levels of negative affect. Total score range from 5-25. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical Impairment Assessment, subscale social | Counted from treatment start: at day 1, 4, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60 | Assessment of eating disorder related psychosocial impairment, subscale focusing on social impariment. 5 items scored 0-3. Higher scores indicate higher impairment. Total score range from 0-15. |
| Eating Disorder Examination Questionnaire 6.0 | At pre-treatment assessment one week before treatment start; at post-treatment assessment at day 63 counted from treatment start; and at follow-up assessment at day 153 counted from treatment start. | Assessment of eating disorder symptoms. 28 items scored 0-6. Higher scores represent more eating disorder pathology. Scores are summerized and scaled, giving a total score ranging from 0-6. |
| Normalized eating pattern | Counted from treatment start: at day 1, 4, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60 | Self-assessment of eating patterns, developed by the authors for use in the present study. The self-assessment includes 2 questions: 1. How many of the previous three days have you eaten regular meals approximately 6 times per day? 2. How many of the previous three days have you eaten normal sized portions at all or almost all meals? Items are scored 0-3. Higher scores indicare more normalized meal habits. Lower scores indicate disordered eating. Total score range from 0-6. |
