Abstract: (2787 Views)
Objectives: Musculoskeletal disorders, including back pain, are increasingly prevalent among school-aged children. Poor postural habits and improper backpack carriage are significant contributing factors. However, there is currently no comprehensive, standardized tool available to assess children’s knowledge of ergonomics related to spinal health.
Methods: This methodological study involved the development of a questionnaire through a seven-step process. Following the creation of the preliminary version and assessment of face validity, content validity was evaluated using the Content Validity Index (CVI) and Content Validity Ratio (CVR) by ten experts. The reliability of the instrument was assessed using a test-retest procedure with 15 students and internal consistency was evaluated using Cronbach’s alpha coefficient with a sample of 180 students.
Results: The final version of the questionnaire, entitled Kids’ Spine Ergonomics Awareness (KidSEA), comprised 13 items across three domains: "Spinal Anatomy," "Correct Posture," and "Ergonomics of Carrying School Supplies." The CVI and CVR for each item exceeded 0.79 and 0.62, respectively, indicating that all items were validated. Cohen’s kappa coefficient for individual items was above 0.41, and the overall Cronbach’s alpha was 0.74, demonstrating acceptable levels of reliability and internal consistency.
Conclusion: The KidSEA questionnaire is a valid and reliable instrument for assessing knowledge of ergonomic principles related to spinal health in children. It can be utilized to evaluate health literacy concerning spinal care, design targeted interventions, and inform educational programs for children in the studied age group. Further studies are recommended to establish the validity of the instrument across different age groups.
