Yes, there’s a strong connection between sameness and anxiety in autism. Many autistic individuals rely on fixed routines and predictability, and when that structure is disrupted, anxiety levels often rise. This behavioural pattern known as sameness insistence is not just a preference but often a coping mechanism. 

When routines change unexpectedly, the autistic brain may struggle to adjust quickly. This can lead to feelings of overwhelm, confusion, and even panic. The predictability of sameness offers safety, so when that’s removed, stress responses can spike. In this way, sameness and anxiety in autism are often two sides of the same coin. 

For some, this links closely to autism rigidity and anxiety, where mental and behavioural inflexibility can heighten emotional sensitivity to change. In other cases, insistence on sameness and stress manifest as intense reactions to relatively minor shifts in environment or schedule. Repetitive routines may also stem from autism worry patterns, where the mind fixates on avoiding unknowns.
