Identity refers to our sense of who we are as individuals, as members of social groups and how others perceive and label us. Identity construction is a complex and often challenging process for autistic people. Considering the ubiquity of online spaces, which have a great influence on the formation of opinions and attitudes, it is important to look at the relationship between content about autism on online platforms and the opinions of autistic people about the impact of this content on their identity. Considering that identity is socially constructed, it is important to research the opinion of autistic people about the impact interaction with other autistic people in online spaces had on their identity. Previous research shows that online platforms can be a useful tool for autistic people to communicate, process information and content, and interact with other autistic people in safe spaces. The aim of this research is to gain insight into the reflections of autistic people on the impact of content about autism in online spaces, as well as the impact of interaction with other autistic people in online spaces on their self-perception and behaviors that affirm their autistic identity. Four autistic persons over the age of 18 participated in the research, two of whom are of Croatian, and the other two are of Irish and British nationality. Research results were obtained using thematic analysis of semi-structured interviews conducted using Zoom. Participants reported a greater understanding and acceptance of their own autistic features, a greater sense of pride in their autistic identity, and a less frequent use of masking as consequences of viewing content about autism in online spaces. Participants also describe a greater sense of understanding of their own identity, relating with others, and being more open about their autistic identity as consequences of interacting with other autistic people using online spaces. Findings of this research also include reports about the participants' habits in online spaces, types of content about autism they encountered in online spaces and the nature of interacting with other autistic people using online spaces.
