Background and study aims
Childhood obesity is a growing problem, and because of the severity of the negative consequences, it needs to be dealt with as soon as possible. The current treatments for childhood obesity are working, but only in short term and only moderately. Therefore, there is a need to search for the underlying mechanisms to improve the existing treatments. A possible underlying mechanism is emotion regulation. Emotion regulation refers to the processes by which people influence which emotions they have, when they have them, and how they experience and express these emotions. When high levels of stress are regulated in an inadequate way, this can contribute to the development of obesity. Three processes are playing a role. Stress increases the production of the hormone cortisol, which may result in accumulation of fat. Low grade inflammation triggered by emotional distress may result in increased food intake and obesity. Emotional eating (eating to satisfy emotional needs) is also higher in children and adults with obesity, in comparison with average weight individuals. The aim of this study is to find out whether emotion regulation training results in less emotional eating and improves maintenance of weight loss.
Who can participate?
Youngsters aged 10-14 who are involved in a residential obesity treatment program
What does the study involve?
Participants are randomly allocated to receive either care as usual or Emotion Regulation Training (ERT) on top of care as usual. The ERT consists of 10 weekly sessions. Booster sessions are given 1, 3, 6 and 9 months after the end of this training. The participants are tested before and after the training and at 6 and 12 months follow-up to measure their use of emotion regulation strategies and changes in eating behaviour.
What are the possible benefits and risks of participating?
It is expected that the youngsters who receive ERT will use more adaptive emotion regulation strategies with less emotional eating and maintenance of weight loss at 6 and 12 months follow up. Improving the current childhood obesity treatments is the purpose of this study. If the treatment is found to be effective, the next step is to use it in a larger group of treatment centers.

| Scientific title | Improving weight control and long-term treatment effects in young adolescents with obesity via emotion regulation training |
| Study objectives | The trialists expect that adding an emotion regulation training (ERT) to the care as usual results in: 1. The use of more adaptive emotion regulation strategies 2. Less emotional eating 3. Improved weight-loss maintenance 4. Better long-term treatment effects compared to care as usual only (CAU-only), reflected in different outcome measures (see below) . |

| Intervention | The recruitment consists of two waves of children entering the clinic (2018 and 2019). At entrance in the inpatient treatment clinic (July-August 2018, 2019) and after consent, participants are randomly assigned to either the ERT+CAU condition or to a CAU-only control condition. Randomization is stratified on age and gender. Before the beginning of the ERT (September 2018, 2019), the baseline measurement is conducted (August 2018, 2019). The ERT runs from September (2018, 2019) till December (2018, 2019). After the ERT measurements will take place post training (December 2019, 2020), 6-month follow up (February, 2019, 2020) and 12-month follow up (August 2019, 2020). The intervention concerns an emotion regulation training (ERT): a group training of 10 sessions (duration 2h per session) on top of care as usual, namely the Multidisciplinary Obesity Treatment (MOT). The 10 sessions will be spread over 10 weeks. The groups are formed with max. 4 to 5 children/adolescents. The ERT (emotion regulation training) will be given at the start of the treatment in the residential treatment center. Booster sessions will be provided at 1 month, 3 months and 6 months after this training. After every session the participants will also receive homework, making them exercising the competence or emotion regulation strategy they learned. The content of the ERT is based on the training of prof. dr. Mathias Berking (Berking, M. & Whitley, B. (2014). Affect Regulation Training: A Practitioners' Manual. Houten: Springer). In the first 5 training sessions, the following basic competencies are learned: exploring feelings; learning about the basic feelings and the intensity of these feelings; body scan (where do I feel these feelings in my body?); abdominal breathing; emotional awareness; psycho- education on the influences of thoughts – feelings and behavior on each other and psycho- education on the function of emotions: learning to see negative emotions as allies. In the next 4 sessions the participants will be learned each time 1 emotion regulation strategy: Distraction; Acceptance; Cognitive Reappraisal and Problem Solving. In the last session the basic competencies and the emotion regulation strategies will be recapitulated. The CAU (care as usual) consists of: 1. Psycho-education on food and physical activity 2. Therapy sessions on diet/healthy eating 3. Physical activity (4h a day) and healthy food habits 4. Parents are involved in therapy 5. Protocols about psychological aspects: problem solving, social competencies and self-worth 6. Individual sessions with a psychologist (every 2 weeks = Cognitive Behavioral Therapy) |

| IPD sharing plan | The data is saved on a server of the University Ghent. Three types of data will be stored: questionnaire data, behavioural data and physiological data. Raw data of the questionnaires and behavioural data will be saved as .txt files, the physiological data will be stored as .edf files. Data storage fact sheets are used to document the meta-data. These files describe the transition from raw data to processed data and contain information about the variables and the encompassing datasets. The data storage fact sheets are stored on the local server of the department of the UGhent. Data about the informed consents, and the file linking participants numbers and names/contact information will be collected in a password-protected file. In this study there will be personal or confidential data collected. No personal information of participants will be coupled to the gathered data in any way. Participants' codes will be in the entire study (with the informed consents as only exception). The personal information will be saved according the law of privacy of 08/12/92. Participants will be informed about this in the informed consent. For sharing data, a protected USB flash drive is provided, filtered according the limitations as stated in the privacy and ethical commissions. |
