Eric Duku is currently investigating the factors that challenge the measurement invariance of constructs used in comparative studies in early child development (ECD) research and ways to ensure that instruments used minimize bias as much as possible. This involves working with Magdalena Janus’ team coordinating annual data collections using the Early Development Instrument (EDI), performing the data analyses, supporting EDI-related projects in a number of countries around the world, and contributing to the ECD Module in the UNICEF’s Multiple Indicator Cluster Survey (MICS).  The team is currently analyzing preliminary data on an Early Child Development Index (ECDI) and other ECD indicators from the ECD module.  Scott Davies, Magdalena Janus and Eric are also studying the educational trajectories of children from kindergarten through to Grade 3 in partnership with EQAO.  With Peter Szatmari and other investigators, Eric is working on the Pathways in ASD study, a multi-site study to examine the developmental pathways of children with ASD and to identify the variables that influence these pathways.  The Pathway study is in Phase II, following these children through the early years of primary schooling.
