The aim of the intervention is to prevent more fatigue-related disabilities in young people with chronic illnesses like inflammatory bowel disease, childhood cancer, and juvenile idiopathic arthritis by improving self-confidence in managing fatigue (fatigue-related self-efficacy or FSE).\n\nThe main questions this study aims to answer are:\n\n* What is the effect of the Booster intervention on fatigue-related self-efficacy (FSE)?\n* What is the effect of the Booster intervention on fatigue levels, school participation, life satisfaction, and perceived health?\n* When does improvement in study outcomes happen relative to the Booster intervention?\n* What participant characteristics predict change in study outcomes?\n\nParticipants will follow the Booster intervention. Booster is a personalised, blended care intervention designed to help young people understand how their thoughts, feelings, and activities impact their fatigue using a smartphone app. The Booster app uses experience sampling methodology (ESM) to track these fluctuations. Based on insights obtained from these data, the participant and their healthcare provider can set personal lifestyle goals, such as increasing physical activity and reducing daytime naps. An earlier version of this intervention, called PROfeel, was effective in reducing severe fatigue. The investigators have now improved the app to also help with setting and achieving personal goals and monitoring daily progress.\n\nThe investigators will measure the effect of Booster through daily questionnaires during two phases: Phase A (baseline, before the goal setting between patient and healthcare provider) and Phase B (intervention, starting in the lifestyle change period). The duration of Phase A will be randomised for each participant.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '18 Years', 'minimumAge': '12 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Experiencing fatigue for at least 3 months and feeling hindered by it (Pediatric Short Fatigue Questionnaire (pSFQ) score of 15 or higher)\n* Diagnosed with a chronic health condition or treated for childhood cancer\n\nExclusion Criteria:\n\nRegarding other treatments:\n\n* Fatigue fully explained by a somatic or psychiatric diagnosis\n* Chronic health condition unstable in the last 3 months (e.g., recent medication changes or cancer relapse)\n* Significant functional limitations due to fatigue (e.g., more than 50% school absenteeism)\n\nRegarding feasibility:\n\n* Cognitive impairment with an estimated IQ of below 70\n* No smartphone with internet access\n* Unable to speak, read, understand, or write Dutch'}, 'identificationModule': {'nctId': 'NCT06562335', 'briefTitle': 'The Blended Care Intervention "Booster" for Youth With Chronic Health Conditions to Increase Fatigue-related Self-efficacy', 'organization': {'class': 'OTHER', 'fullName': 'UMC Utrecht'}, 'officialTitle': 'Blended Therapy for Youth With a Chronic Health Condition to Increase Fatigue-related Self-efficacy (Booster): Protocol for a Multiple Baseline Single Case Experimental Study', 'orgStudyIdInfo': {'id': '24U-0152'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Booster intervention', 'description': '* Start conversation: participant personalises the Booster app, supported by the Booster practitioner\n* Measurement period: the participant fills out short repeated questionnaires 5 times daily for 4 weeks in the Booster app. This method is called experience sampling methodology (ESM).
