Specific interests as a social boundary and bridge: A qualitative interview study with autistic individuals

Growing evidence shows that specific interests can help autistic individuals cope with difficulties in social communication and interaction. However, it is unclear which specific characteristics of these interests make them suitable for this coping role. Therefore, this study explored how specific interests can help autistic individuals navigate social communication and interaction. We conducted semi-structured interviews with nine autistic individuals to inquire about their perspectives on the meanings and functions of their specific interest in their (social) life. We found that specific interests served two important social functions. First, the interests provided a way to disconnect from the challenging outside world, through a shift in the attentional focus of participants. Second, the interests served as a "social compass," providing structure and meaning to social situations and helping the participants feel more connected to others. Based on these findings, we propose a conceptual model suggesting that specific interests create the experience of a "protective boundary" between oneself and others, which helps autistic individuals feel safe during social interactions. Namely, engaging in specific interests not only creates a space where autistic individuals can retreat when they feel overwhelmed, but also provides a framework with delineations in time and space, as well as explicit rules for social interactions, which make them more predictable and regulated. The study suggests that incorporating specific interests into therapy can help improve social communication and interaction for autistic individuals while still prioritizing their personal well-being.
