Anxiety is a common co-occurring condition for autistic students; however, little is known about how anxiety may affect their social or academic outcomes in an educational setting. Furthermore, the perspectives of students themselves have rarely been included in the literature. Using Q-sort method, 45 autistic participants aged 7 to 17 years identified the outcomes they perceived were most impacted by their anxiety in the educational setting. The three outcomes most highly rated as being impacted by anxiety overall were academic outcomes. Using by-person factor analysis, six distinct factors, or 'viewpoints', were identified. These viewpoints reflect different combinations of outcomes affected by anxiety, including missing school or activities, reduced interactions with friends, reduced classroom communication and finding it harder to complete schoolwork. This study adds to the literature by using Q-sort method to enable autistic children and adolescents to report the impacts of their anxiety. Anxiety has additional impacts on the social and academic outcomes of autistic students, highlighting the need for increased awareness and training for parents and professionals, an individualised approach to student support and further research regarding the relationship between anxiety and academic outcomes.
