Objectives: The objectives of our study are two-fold. The first is to clarify the relationships outlined above and to compare the new edition of the Vineland to another measure, the ABAS-II. The second is to extend the age-range downward from that reported in previous studies, by comparing these two measures in a group of 3-year olds with and without ASD.
Methods: To date, we have studied 28 toddlers (21 males, 7 females; mean age = 38.64 months, SD = 2.95). All children were recruited as part of the Infant Brain Imaging Study (IBIS). At the age of 3, diagnostic status is confirmed using clinical judgment, taking into account developmental (Mullen Scales of Early Learning (MSEL) and adaptive functioning (Vineland-II), ADOS, and ADI-R. For the purposes of these preliminary analyses, participants were grouped into ASD (n = 9) versus Non-ASD (n = 19), but participants will be stratified by specific autism diagnosis, as well as by specific developmental delay in our final analyses. Total, standard, and calibrated scores from multiple measures will be used to compare these toddlers.
