Objective

To develop a quality assessment scale for children's musculoskeletal disorders health short videos and evaluate its reliability and validity.

Methods

The initial scale was developed through literature review, semi-structured interviews, and Delphi expert consultation. A total of 240 health short videos on children's musculoskeletal disorders were selected from Douyin as research subjects and evaluated by two raters. The 480 datasets were randomly divided into two groups for item analysis and reliability/validity testing.

Results

The scale consisted of 22 items across five dimensions (presentation literacy, creator authority, information comprehensibility, video production quality, and audience feedback). The item-level content validity index and scale-level content validity index were both 1.00. The scale demonstrated a Cronbach's α of 0.812,inter-rater reliability of 0.872, and test-retest reliability of 0.914. All items had factor loadings above 0.400, and the cumulative variance explanation rate of the five dimensions was 67.464%. Confirmatory factor analysis indicated good model fit.

Conclusion

The quality assessment scale for children's musculoskeletal disorders health short videos exhibits good reliability and validity, effectively evaluating the quality of relevant short videos.
