Validation of the Korean Version of the Responsive Adult-Child Engagement During Shared-Book Reading Scale

Background and Objectives The Responsive Adult-Child Engagement During Shared-Book Reading (RACED-SBR) scale was developed to measure parent and child behaviors during shared book reading interactions. This study aimed to translate the scale into Korean, conduct linguistic validation, and evaluate the effectiveness of the Korean version (K-RACED-SBR). Subjects and Method The RACED-SBR was systematically translated into Korean using a multi-step approach. A bilingual translator conducted a back-translation, which was compared with the original version to ensure accuracy and consistency. After cognitive debriefing with experts, the K-RACED-SBR was administered to 46 parent-child dyads, including 31 dyads of normal-hearing parents and their normal-hearing children and 15 dyads of normal-hearing parents and their children with hearing loss, for cognitive validation. Parent and child behaviors during video-recorded shared book reading interactions were analyzed. Results The translation of the K-RACED-SBR was completed through forward translation, reconciliation, back-translation, cognitive debriefing, and final proofreading. The scale demonstrated strong internal consistency and high test-retest reliability. Confirmatory factor analysis revealed that the scale comprised five subsections: three subsections for adult shared book reading behaviors and two for child shared book reading behaviors. The scale identified significant differences in the total scores for adult and child shared book reading behaviors between the two groups. Conclusion The K-RACED-SBR was successfully translated and linguistically validated. This scale provides valuable quantitative and qualitative insights into parent-child interactions during shared book reading, particularly for children with hearing loss. It has potential applications in both research and clinical settings to support early language development interventions.
