123 Developmental Trajectories of Children with
Autism Spectrum Disorder
3:45 PM - 4:45 PM - Grand Ballroom AB Level 5
Organizer: S. Georgiades; McMaster University
Many longitudinal studies in ASD have documented
considerable variation in outcome, ranging from
remarkable improvement in some children to a decline
in others. However, these results are limited by
issues such as employment of convenience sampling
frames, data collection from few time points, and use
of small sample sizes. More recent data suggest a
new way of thinking about the developmental course
of ASD, in which children are described using distinct
homogeneous trajectories, rather than a single
heterogeneous group. This panel presents findings
from two new longitudinal studies that benefit from
large sample sizes, ascertainment of inception cohorts,
data acquisition at multiple time-points, use of several
outcomes including social-communication symptoms
and functioning and problem behaviors, and novel
statistical techniques. The findings emphasize that
children with ASD follow distinct trajectories both over
the short and long term and that this heterogeneity in
developmental course needs to be taken into account in
treatment planning.

124 Earlier Is Better and More Difficult:
Opportunities and Challenges in Screening
Children for An Autism Spectrum Disorder (ASD)
in the General Population During the Second
Year of Life
3:45 PM - 4:45 PM - Grand Ballroom F Level 5
Moderator: C. E. Rice; National Center on Birth Defects and
Developmental Disabilities
Organizer: C. E. Rice; National Center on Birth Defects and
Developmental Disabilities
Recently, there have been advances in understanding the
early signs of ASDs with increased public health focus on
early developmental screening. The American Academy of
Pediatrics now recommends that all children be screened
for developmental disabilities throughout the first few
years of life and for ASDs at 18 and 24 months. Despite
wide consensus that “earlier is better,” knowledge gaps
exist in what “early” means and how this is successfully
implemented in general population settings. Although
several screening instruments have been developed for
use in the 2nd year of life, data on their utility in general
population settings are limited. Unlike families in clinicallyreferred
or sibling research projects who may have
heightened concern, families in the general population
may be confronted with positive screening results before
they have raised concern themselves. This panel presents
the latest data on early ASD screening tools used in
general population settings and explores opportunities
and challenges in the during the 2nd year of life.
