Items were evaluated for relevance, clarity, and alignment with theoretical domains. The items that demonstrated strong validity, expert agreement, and alignment were retained, while those with lower scores or cross-domain overlaps were considered for exclusion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The analysis revealed high content validity, with most items achieving CVR and I-CVI values above the acceptable thresholds. The FVI indicated strong factorial validity across all domains, with no major discrepancies in domain assignments. IRA and Fleiss\u2019 Kappa further confirmed the consistency of expert ratings. A simplified version of the SDSC was developed, retaining core items addressing sleep latency, night awakenings, breathing disturbances, and daytime somnolence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This study provides a refined version of the SDSC with improved psychometric properties, suitable for pediatric dentistry applications. The simplified tool ensures that relevant sleep disturbances are effectively captured, offering a practical screening tool for clinicians in both pediatric and dental settings.
