Background: Social stigma is a barrier for students with autism on college campuses. The purpose of this study is to examine the relationship between autism knowledge and autism stigma endorsement.
Method: 144 college undergraduate students were asked to complete the Autism Stigma and Knowledge Questionnaire as well as a brief demographic questionnaire. The relationship between stigma endorsement and ASD knowledge in the areas of diagnosis and symptoms, etiology, and treatment were evaluated using a multiple linear regression. Two independent-sample t-tests were conducted to investigate group differences between participants who know someone with autism and those who do not as well as between male and female participants.
Results: A significant regression equation was found (F(3,140) = 51.35, p = .000), with an R2 of .52. While Treatment and Etiology subscale scores significantly predicted Stigma subscale scores, Diagnosis/Symptom subscale score was not. In terms of knowing someone with an autism diagnosis, there was a significant difference in ASD diagnosis and symptom knowledge (t(142) = 4.16, p = .000), etiology knowledge (t(142) = 3.51, p = .001), treatment knowledge (t(62.99) = 3.54, p = .001), and stigma endorsement (t(142) = 3.03, p = .003). No significant differences were found between male and female participants.
Conclusions: Contrary to past studies, gender was not associated with ASD knowledge or stigma endorsement. This study suggests that an intervention designed to increase ASD knowledge, particularly in the areas of etiology and treatment, and to increase contact with students diagnosed with autism would be effective in reducing ASD stigma.
