 This study investigated how different factors such as age, gender, autism knowledge, contact with autistic people, and autistic traits influence attitudes towards autistic people. The results showed that greater autism knowledge and increased contact with autistic people was associated with more positive attitudes towards autistic people. Therefore, public awareness campaigns to increase knowledge about autism and encourage contact between autistic and non-autistic people could help reduce stigmatization of autistic people.
