The goal of this research study is to develop an online questionnaire about what youth with Autism Spectrum Disorder (ASD) eat and how it impacts their daily lives. Youth and their parent(s) will complete a questionnaire about food and eating habits online. Parents will complete an additional child background and medical history questionnaire online. Participants will be paid for their time with an Amazon online gift card. For more information or to enroll, please visit the What Do You Eat study page.
