Researchers: John A. Tsiouris, M.D., and Ira L. Cohen, Ph.D of the NYS Institute for Basic Research in Developmental Disabilities

Purpose of the Study:  We are looking for associations between biological factors and whether or not a person with autism shows aggressive or self-injurious behaviors. Therefore, please fill out the form whether or not this person shows significant aggressive behaviors.

How long will it take? Participation involves completion of an online questionnaire, which will only take approximately 10-15 minutes.

Who can participate? We are inviting all families who are able to provide information about their children with an ASD, regardless of whether or not they display aggressive behaviours.

How can I participate? Login or register. After you have logged in just click on the name of the child for whom you are completing the questionnaire about, and then click on the questionnaire "Modified Overt Aggression Questionnaire."
