| Scientific title | Empowering Parents of Obese Children: development and controlled evaluation of an obesity-specific parenting skills training |
| Study acronym | EPOC |
| Study objectives | A compact parent training enhancing "obesity-specific" parenting skills combined with written information and a training video contemporaneous with the inpatient training of the children leads to a greater reduction of percentage overweight (BMI-SDS) in the obese children and an improvement of children and parents' psychosocial variables one year after the end of intervention compared to a parent group only receiving written information. |
| Ethics approval(s) | Ethics Committee of the University of Potsdam, 19/05/2006 |
| Health condition(s) or problem(s) studied | Obesity |
| Intervention | Parent training course (intervention group) vs written information only (control group) Parent training course: Key activity: Cognitive-behavioral training, focusing on how parents can support their children at home in critical behavioural tasks (increasing physical activity, dietary changes). Materials and techniques: Group discussions, role play, work sheets, introduction of critical situations (video), take-home video and take-home written information. The participants will be taught by health professionals of the participating clinics (psychologists, pedagogues, nutritionists, dieticians, etc.) Duration of the course: 2 days (in most instances weekend-course), 10 sessions, on average 50 minutes per session Topics/contents of the written information provided to the control group: 1. Etiology of obesity 2. "Traffic light" diet 3. Advice on increasing activity (physical exercise and daily motor activity) 4. Dietary changes |
| Intervention type | Other |
| Primary outcome measure | BMI-SDS in children, assessed at T1, T2, T4, T5 and T6 (assessed by a physician, an interview and a questionnaire) Timepoints: T1: Start of the child's inpatient stay T2: End of the child's inpatient stay T3 (Applicable only for the intervention group; timepoint when a telephone booster session takes place) : One month after the child's inpatient stay T4: Three months after the child's inpatient stay T5: Six months after the child's inpatient stay T6: Twelve months after the child's inpatient stay |
| Secondary outcome measures | 1. Psychosocial variables of parents: 1.1. Self-efficacy, assessed at T1, T2, T4, T5 and T6 by questionnaires and an interview 1.2. Psychosocial strain, assessed at T1 and T6 by the Short Form (SF)-12 State of Health Questionnaire 1.3. Familial support, assessed at T1, T4, T5 and T6 by questionnaires and an interview 1.4. Feeding style, assessed at T1, T4, T5 and T6 by the Child Feeding Questionnaire (CFQ), Caregiver's Feeding Styles Questionnaire (CFSQ) and an interview 2. Psychosocial variables of children: 2.1. General quality of life, assessed at T1, T4, T5 and T6 by a children's quality of life questionnaire (KINDL) 2.2. Weight-related quality of life, assessed at T1, T2, T4, T5 and T6 by a weight-related quality of life questionnaire (GW-LQ-KJ) and an interview 2.3. General self-efficacy, assessed at T1, T2, T4, T5 and T6 by questionnaires 2.4. Weight-related self-efficacy, assessed at T1, T4, T5 and T6 by a weight-related self-efficacy questionnaire (GW-SW-KJ) 2.5. Eating behaviour, assessed at T1, T4, T5 and T6 by the Eating Behaviour Questionnaire (FKE-KJ) 2.6. Activity behaviour, assessed at T1, T4, T5 and T6 by the German Health Interview and Examination Survey for Children and Adolescents questionnaire 2.4. Familial support, assessed at T1, T4, T5 and T6 by a questionnaire 2.5. Psychosocial strain, assessed at T1 and T6 by the Strengths & Difficulties Questionnaire (SDQ) Timepoints: T1: Start of the child's inpatient stay T2: End of the child's inpatient stay T3 (Applicable only for the intervention group; timepoint when a telephone booster session takes place): One month after the child's inpatient stay T4: Three months after the child's inpatient stay T5: Six months after the child's inpatient stay T6: Twelve months after the child's inpatient stay |
