Re-Examining the Cognitive Scale of the Developmental Support in Childcare

The Cognitive Scale of the Development Support in Childcare (CSDSC) developed in 2023 has adequate reliability and validity. However, it has some limitations in terms of its factor structure. Thus, we re-examined the structural factors, reliability, and validity of the scale using the same data (513 valid responses) as in the original study. In contrast to the two-factor model of the original scale, the revised scale has a one-factor structure. The scale’s Cronbach’s α value was 0.83. A confirmatory factor analysis used to assess whether a one- or two-factor structure was more appropriate for the scale demonstrated that the one-factor model was a better fit, and the revised scale had a higher degree of validity than the original one. The results indicate that the revised and shortened CSDSC has sufficiently high levels of reliability and validity, suggesting that the scale is appropriate for evaluating nursery teachers’ values regarding child development support in childcare.
