How does autism relate to anxiety in forming new friendships? 

Making new friends can be difficult for anyone, but for autistic people, it often comes with added layers of anxiety. Research from the NHS and NICE shows that differences in communication style, sensory processing, and social expectations can make forming friendships more stressful and unpredictable, even when the desire for connection is strong. 

Why anxiety and friendship often overlap in autism 

Several factors make friendship-building uniquely challenging for autistic people. 

• Social communication differences such as reading tones of voice, facial expressions, or unspoken social rules can lead to misunderstandings and self-doubt. The Newcastle Hospitals NHS Foundation Trust explains that these differences are core to autism and can naturally increase anxiety in new social situations. 

• Sensory sensitivities like discomfort from noise, lighting, or physical proximity can make group settings feel overwhelming, leading to avoidance or fatigue. NICE guidance on autism support for under 19s (CG170) and the NHS Quality Standard (QS51) both highlight the need for quieter, low-arousal environments to reduce sensory-related stress. 

• Rejection sensitivity and a history of feeling misunderstood can heighten fear of social judgment. The National Autistic Society notes that many autistic people experience anxiety around being accepted, which can lead to masking: hiding autistic traits to fit in, often at a cost to self-esteem and mental health. 

Researchers also describe a “double empathy problem,” where both autistic and non-autistic people can struggle to understand each other’s perspectives. This two-way communication gap can create tension and loneliness even in friendly settings, reinforcing social anxiety. 

How common is social or friendship anxiety in autism? 

Clinical evidence shows that anxiety affects between 40% and 59% of autistic people at a level that disrupts daily life, according to NICE surveillance reviews and NHS data. Studies cited by the National Autistic Society suggest that up to 70% of autistic children and adults report loneliness or difficulty maintaining friendships. 

Anxiety linked to friendships appears higher in adolescence and in people assigned female at birth: groups more likely to mask or internalise distress. NICE 2025 surveillance of CG170 notes that social participation remains a key area where targeted support can reduce long-term anxiety. 

Practical ways to make friendship-building easier 

Guidance from the NHS, NICE CG142, and the National Autistic Society all recommend approaches that focus on acceptance, predictability, and self-advocacy rather than forcing neurotypical norms. 

Helpful strategies include: 

• Peer mentoring and shared-interest groups for activities like Lego clubs, art, or gaming sessions allow friendships to develop naturally with less social pressure. 

• Adapted environments: quieter settings, predictable routines, and sensory adjustments (such as soft lighting or noise-reducing headphones) can lower anxiety and make socialising more enjoyable. 

• Teaching neurotypical peers about autism programmes that promote mutual understanding and inclusion help reduce rejection sensitivity and improve confidence. 

• Social or communication support NICE recommends tailored social skills or peer-based interventions for children and adults, delivered in familiar, low-stress settings. 

• Encouraging self-advocacy using visual support, communication passports, or direct explanations (“I find eye contact hard, but I’m listening”) empowers autistic individuals to express needs without fear. 

These person-centred strategies reflect NICE’s emphasis on reasonable adjustments and acceptance of neurodiversity rather than “fixing” behaviour. 

A reassuring takeaway 

Forming friendships can feel daunting for autistic people, but anxiety isn’t inevitable, it’s often a response to misunderstanding, sensory overload, or past exclusion. By creating accepting environments and valuing different ways of connecting, friendships can become sources of comfort, not stress. 

As NICE and NHS guidance highlights, small changes, from adjusting lighting to building social confidence through shared interests can make a big difference. When the world meets autistic people halfway, friendship becomes not only possible but genuinely rewarding.
