IAN Research Reports

A belief in the value of sharing...

All over the United States, mothers and fathers of children with an Autism Spectrum Disorder are sitting down in front of their computers to contribute their family's data to the IAN Project.  At 3 in the morning from the family PC, or at lunchtime from the office... in one long session or in several smaller ones...they are answering the IAN questionnaires, adding their knowledge to that of thousands of other families.  It is a way to tell their story.

In more traditional studies, research participants rarely hear what resulted from what they gave: their time, their passion, their effort. The IAN team believes that a research endeavor should be more of a two-way street.  We will therefore be publishing Research Reports from time to time so that we can share with families and the entire autism community what we have learned so far. 

As researchers from many fields begin to use the IAN data, applying it to hundreds of autism research questions, there will be even more to report!  Even now, though, we have some preliminary findings based on the raw data flowing in that should be of great interest to our readers.
