Survey data were collected in cross-sectional study. The reliability of IN-Child Record was verified via the internal consistency method; the coefficient of Cronbach’s α were over 0.7. The construct validity of IN-Child Record was also verified via the path analysis using structural equation modeling (SEM). IN-Child Record is valid based on its goodness-of-fit values obtained using the SEM. These results scale that IN-Child Record has high reliability and construct validity.
