RESUMO
AIM: To verify the reliability and validity of a Japanese translation of the Satter eating competence Inventory-2.0™ (ecSI-2.0™) for parents of fifth and sixth grade elementary school students. METHODS: Participants were parents who prepared meals for their children aged 10-12 years. A preliminary study was conducted with 11 parents using semi-structured interviews and questionnaires, followed by a main study of 2,825 parents. Internal consistency and test-retest methods were used to verify reliability. Face and content validity were confirmed in the preliminary study, and feasibility was examined by the valid response rate and response time. Construct validity was verified using factor validity and known population validity. RESULTS: Of the 2,825 persons surveyed, 626 returned valid responses, and among the 60 persons who received the re-survey, 48 returned valid responses. The average score of the Japanese translation of the ecSI-2.0™ was 33.1 (SD ± 7.8) points. Cronbach's alpha coefficient for the whole scale was .87 and ranged from .67-.79 for the four subscales. The test-retest method confirmed the scale's stability. Factor analysis confirmed that reproducibility of the four factors was similar to the original version. In the examination of known population validity, the same correlation as the original edition was confirmed. CONCLUSIONS: The Japanese translation of the ecSI-2.0™ may be reliable and valid for understanding eating competence related to behavior of parents of school-age children.
