Special Interests in Autism: Functions, Benefits, and Challenges

Special interests are a highly prevalent feature of autism spectrum conditions (ASC) and have long been described primarily from a deficit-oriented perspective. More recent work has pointed to their potential as psychological resources, yet systematic evidence and direct comparisons with non-autistic groups remain limited. The present study examined the significance of special interests for well-being, self-related aspects and emotion regulation in autistic adults, as well as negative consequences and stigma. Furthermore, we directly compared the likelihood of engaging in special interests versus seeking social contact across a range of emotional contexts. A total of 182 participants (60 autistic and 122 non-autistic) completed an online survey on multiple aspects of their (special) interests and measures of social anxiety and self-esteem. Autistic individuals reported a stronger role of special interests in emotion regulation and as a source of learning and knowledge, while also experiencing greater stigma and negative consequences compared with non-autistic participants. Autistic participants further showed a higher likelihood of relying on their interests as a coping strategy in negative and exhausting situations, highlighting their particular relevance for emotion regulation. Our findings emphasize the unique functions of special interests in autism and point to their therapeutic potential as adaptive resources.Lay AbstractMany autistic people have special interests - topics or activities they pursue with great passion. We asked autistic and non-autistic adults how meaningful their interests are and how they use them in different emotional situations. Autistic people reported that interests are especially helpful for coping with stress and regulating emotions, and that they are an important source of learning and knowledge. On the other hand, autistic individuals also experienced more stigma and negative reactions from others than non-autistic individuals. Our findings show that special interests are an important source of well-being and should be recognized as a valuable resource in autism.
