Prior studies have shown inconclusive evidence on how knowledge predicts attitude towards individuals with autism spectrum disorders (ASD) in diverse cultural contexts. There is also dearth of research on psychological resources that facilitate inclusive attitude towards students with ASD. This study examines the links of kindness and knowledge about autism to attitude towards ASD among Filipino high school students. An online survey with items measuring kindness and knowledge about autism as well as a vignette-based measure of attitude towards ASD was administered to participants. Results showed that knowledge about autism and kindness positively predicted attitude towards ASD when controlling for age, gender, and previous contact with students with ASD. This research suggests that integrating ASD awareness with kindness education can bolster positive attitude towards persons with autism and other developmental disabilities.
