Validity and Reliability Study of the Chinese (Traditional) Version of the Devereux Early Childhood Assessment for Toddlers (DECA-T).

The C-DECA-T showed good psychometric properties. Our findings of high internal consistency of the three subscales and total score of the C-DECA-T suggest symptom manifestation of social-emotional competence and needs in Taiwanese toddlers is not culturally different from American toddlers. The clinimetric properties of the C-DECA-T examined by a classical test theory analysis approach and an item response theory analysis approach suggest that the C-DECA-T is a reliable and valid instrument for measuring social-emotional strength and needs in the population in Taiwan.
