About this trial
Our study aims to determine whether omega-3 fatty acid supplementation can improve sleep, mood, and behavior in children with sleep problems and symptoms of Autism Spectrum Disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), or both. By using a transdiagnostic approach-focusing on specific symptoms rather than diagnostic labels-we aim to identify which children may benefit most from omega-3 supplementation, thereby enhancing inclusivity. Many previous studies have excluded children with both ASD and ADHD, or those without a formal diagnosis.

Trial outcomes
Primary outcomes
Changes in the network structure of symptoms before and after intervention.
This involves identifying shifts in symptom interconnectivity, which can indicate improvements in symptom clustering (e.g., a reduction in connections around "bridge" symptoms like emotional dysregulation or sleep disturbances). All questionnaires mentioned in secondary outcomes are used in the network.
