This study examined the impact of these interventions on two primary domains: emotion regulation and ADHD/hyperactivity symptoms.</p> <p><strong>Methods and Materials: </strong>This experimental study employed a pretest-posttest design. Participants included 34 children diagnosed with ADHD (17 per group) who received sleep-based cognitive behavioral interventions. Data were collected using standardized instruments, including the Emotion Regulation Checklist – Parent Form (Shields &amp; Cicchetti, 1995), the Pittsburgh Sleep Quality Index (PSQI) (Buysse et al., 1989), and the Conners’ Rating Scale (Conners, 2008). Analyses were conducted using analysis of covariance (ANCOVA) in SPSS version 26.</p> <p><strong>Findings:</strong> Findings indicated that sleep-based cognitive behavioral interventions improved overall sleep quality and its associated components, enhanced satisfaction with sleep, and positively affected daytime functioning (p&lt;0.01). Additionally, these interventions contributed to improved emotion regulation performance and reduced emotional negativity/lability among the children.</p> <p><strong>Conclusion:</strong> The study demonstrated that sleep-based cognitive behavioral interventions can enhance emotion regulation processes in children with ADHD, while also increasing sleep quality and overall daily functioning.</p> https://www.maherpub.com/index.php/jndd/article/download/868/676
