To promote knowledge and acceptance of autism, Sesame Workshop created an online initiative: "See Amazing in All Children." This nationwide evaluation of "See Amazing" assessed whether it increased knowledge and acceptance, promoted community inclusion, reduced parenting strain, and enhanced parenting competence. Survey responses were collected online from parents of children (age [less than or equal to] 6) with and without autism before (N = 1010), 1 week after (N = 510), and, for parents of autistic children, 1 month after (N = 182) they viewed the "See Amazing" materials. Following exposure, parents of non-autistic children showed small but significant increases in knowledge of autism and, like parents of autistic children, greater acceptance of autistic children. Parents of autistic children reported less strain, increased parenting competence, and more hope about involving their child in their community. That the "See Amazing" materials invoked positive changes in the general parent community and in parents of autistic children suggests that "See Amazing" materials have the potential to be an effective resource to increase acceptance and community inclusion, although limitations of self-selection, dropout rate, and lack of control group constrain interpretation. Implications include support for targeting acceptance as a step beyond awareness campaigns, though actual behavior change is a subject for future research.
