Objective: This study aimed to develop and validate a media literacy scale for the parents of young children. Methods: Initial items were generated through a literature review, concept map research, and focus group interviews, producing 137 items. After three rounds of content validity review by experts, the scale was reduced to 58 items. A preliminary survey of 450 parents and exploratory factor analysis refined the scale to 57 items across three factors. The main survey of 634 parents was conducted using confirmatory factor analysis and tests of convergent, discriminant, criterion, and predictive validity, as well as reliability. Results: The final scale included 57 items: 14 for Media Analysis (8 for content analysis, 6 for influence analysis), 14 for Media Communication (7 for responsible communication, 7 for safe communication), and 29 for Media Access and Utilization (10 for media use, 11 for media control, 8 for media utilization). Convergent validity was supported by factor loadings above .50, an AVE of .58–.77, and a CR of .91–.96. Discriminant validity was established as AVE exceeded r² values and confidence intervals of factor correlations did not include 1. Criterion validity was confirmed through significant correlations with the K-NMLS-SF (r = .43–.60). Reliability was high, with Cronbach’s α of .97 for the total scale, .92-.97 for factors, and .89-.96 for subfactors. Conclusions: The finalized 57-item scale is reliable and valid for assessing parental media literacy. It can be used in education, counseling, and research.
