This study aimed to identify the attributes that autistic people perceive as positively and negatively impacting on their identity and wellbeing. In Study 1, we recruited 140 autistic participants for an online survey. Participants completed autism social identification and collective self-esteem measures and listed attributes they associated with autism. In Study 2, we conducted focus groups with 15 autistic people to explore how positively they perceived the attributes of autism. Participants then discussed the autism attributes in relation to their own experiences and identity. We found a positive relationship between the number of positive attributes participants associated with autism, and their collective self-esteem, to the extent that they identified with other autistic people.
