Autistic individuals often experience challenges in social communication and interaction, and there is growing evidence that specific interests can help them regulate these difficulties. However, it is unclear what specific properties of these interests make them suitable for this role. In this qualitative study, we conducted semi-structured interviews with nine autistic individuals to explore the social functions of their specific interests. Data analysis followed Grounded Theory and Interpretative Phenomenological Analysis principles. Our analysis revealed that these interests have two important functions in social communication and interaction. On one hand, they provide a means of disconnecting from the often-distressing challenges in the social outside world. On the other hand, specific interests serve as a social compass: they provide structure and meaning to social reality, can foster a sense of connection with others, and provide an entryway for social participation. Based on these findings, we propose a conceptual model suggesting that specific interests enhance the experience of a psychological boundary between oneself and others, which contributes to a sense of safety during social interactions. Our study suggests that incorporating specific interests into therapeutic interventions can improve the social communication and interaction of autistic individuals, without losing sight of their personal well-being. Lay abstract 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.
