Autistic adults prefer social touch less but engage just as much: The impact of social context, relationship type, sensory responsivity, and psychological factors.

Autistic people face touch-related challenges, yet the factors influencing these difficulties are not well understood. We developed a novel instrument to capture social touch experiences of autistic adults, along with both social and individual factors that influence them. Using a body-painting task and questionnaires, we demonstrated that the perception of touch interactions varies based on social contexts and neurotypes. Autistic adults, on average, prefer touch less, but the type of relationship influences the perceived comfort and meaningfulness of touch similarly in both groups. Regarding the appropriateness, erogeneity, and pleasantness of social touch, the autistic group showed different touch perceptions in professional and friendly scenarios compared to the non-autistic group, whereas touch in intimate scenarios was perceived similarly. Sensory responsivity, touch predictability, social confidence, and touch-related anxiety affect social touch to a greater extent than the non-autistic group. Despite these marked differences in perception, the autistic adults, on average, engage in social touch as frequently as non-autistic adults, and their satisfaction with touch is comparable. Our findings suggest that supporting autistic people would involve understanding their preferences and the contextual factors that contribute to their sense of comfort, rather than excluding them from touch interactions.Lay abstractAutistic people find certain types of touch, particularly light or unexpected touch, uncomfortable or overwhelming. The reasons for this are not fully understood. To address this, we asked both autistic and non-autistic adults how they feel about being touched in different situations and on different parts of the body. We also asked how much they enjoy touch and how they feel about being touched by people in various relationships, such as a partner, parent, or friend. Finally, we looked at how individual traits affect their experience of touch. We found that the autistic group engaged in social touch just as often as the non-autistic group and reported similar overall satisfaction. In intimate contexts, such as with a romantic partner, both groups perceived touch similarly. Both groups agreed that touch from a partner or child is the most meaningful and comfortable compared to other relationship types. Despite some similarities, autistic adults, on average, still reported enjoying social touch less overall and experiencing more touch-related challenges in romantic relationships. They also placed less importance on touch for bonding. Moreover, the autistic group rated touch as less appropriate, less pleasant, or less intimate than the non-autistic group in professional (like physiotherapy) or friendly (like a dance class) situations. While social interaction difficulties influence how both groups experience touch, other factors seem to play a stronger role for the autistic group, such as how predictable the touch is, whether they experience sensory challenges, and how socially confident they feel or how anxious about touch they are. Rather than assuming autistic people dislike touch, it is important to recognise that they may have different preferences, and that certain situations make touch feel more comfortable and enjoyable. Respecting these preferences can help make social touch more positive and meaningful, potentially improving relationship quality with autistic people.
