Dr. Clifford’s research is focused on the development and evaluation of assessment measures that rely on parent completion and/or administration in order to evaluate the development of children ages birth to five in the U.S. as well as internationally. Recent research has also focused on the translation and adaptation of developmental screening measures in order to assist in the identification of children and families who may benefit from early intervention services worldwide. In addition, Dr. Clifford is engaged in the development and evaluation of a curriculum focused on enhancing the social-emotional development of infants and toddlers with disabilities.
