Die DreamChanger-Intervention in Kombination mit einer Bildprobentherapie für Albträume von Kindern

Nightmares, characterized as distressing dreams often leading to awakening, are relatively common in young children. However, approximately 3-6% of children endure recurrent nightmares, occurring at least once per week, causing significant distress and impairment. These persistent nightmares can be idiopathic or post-traumatic, and may be linked to conditions such as nightmare disorder or post-traumatic stress disorder (PTSD). Children experiencing recurrent nightmares face an elevated risk for various maladaptive consequences, including reduced sleep quality and quantity, heightened nocturnal anxiety, and challenges in emotional, social, and academic functioning. Moreover, parents often experience disruptions in their own sleep, which may lead to adverse health outcomes. Hence, the demand for effective interventions to mitigate the multifaceted burdens associated with recurrent nightmares is pronounced.

The most established intervention for children struggling with recurrent nightmares is Imagery Rehearsal Therapy (IRT). This approach aims to diminish the frequency and intensity of nightmares by encouraging children to engage with and modify the content of their nightmares through visualization and rehearsal techniques. Studies assessing the efficacy of IRT in children have demonstrated significant reductions in nightmare frequency and associated distress following treatment. However, the evidence base for this intervention remains limited, with only one small-scale (N=20) randomized controlled trial (RCT) conducted in children to date. Correspondingly, there is a critical need for further research to evaluate treatment effectiveness in children.

Furthermore, despite the promise of IRT in reducing nightmare frequency and intensity, approximately 30% of children do not sufficiently benefit from treatment. This underscores the necessity to refine and tailor this intervention to better address the characteristics of children. To date, research has yet to explore the potential advantages of augmenting IRT with additional components. The DreamChanger intervention offers a novel approach specifically designed for young children experiencing recurrent nightmares. Utilizing a remote-control-like device emitting a soft light, this cognitive intervention empowers children to "change the channel of their dreams", fostering a sense of mastery and control. A recent RCT demonstrated the efficacy of the DreamChanger in reducing nightmares and anxiety in young children. Building upon these findings, we posit that combining IRT with the DreamChanger may enhance treatment outcomes. Encouraging children to utilize the DreamChanger remote during the rehearsal of alternative dream scenarios may establish associations between the remote and alternative dream imagery, potentially improving the mental accessibility of imagery when using the remote at night. Thus, the DreamChanger has the potential to augment IRT by further stimulating the child's imagination and sense of mastery, while also facilitating the rehearsal and accessibility of alternative dream imagery.

This study seeks to advance scientific knowledge regarding interventions for pediatric nightmares by examining the efficacy of a novel treatment approach - a combination of IRT with the DreamChanger intervention - to alleviate recurrent nightmares and improve sleep quality in young children. This augmented intervention will be compared to a waitlist control group in an RCT. The research plan is based on an RCT design, with 2 arms (intervention vs waitlist control) and assessment points at baseline, mid-treatment, post-treatment, and for the intervention group - an additional 3-month follow-up.
