What Makes Social Situations Frightening in Autism

What the review found

Estimates of social anxiety among autistic people reach 50 percent. Among people without an autism diagnosis the figure is 7 to 13 percent. Both numbers are quoted from earlier work in a review published in September 2023, and the distance between them is why the review was written.

Jamal Montaser and six colleagues at the California Institute of Behavioral Neurosciences and Psychology in Fairfield, California wrote it for the journal Cureus. Following PRISMA guidelines, they searched PubMed, Medline and ScienceDirect, screened 2,037 records once duplicates were removed, and kept ten, two of which are themselves narrative reviews. Nothing was pooled into a combined figure; the ten papers were appraised for quality and synthesised in prose, which makes the result an argument about mechanism rather than a quantity.

The question was why social anxiety accompanies autism so often, and whether it arrives for the same reasons as in anyone else. Autistic children meet frequent rejection, the review notes, and grow quiet and withdrawn in response, and quiet withdrawal is also what social anxiety disorder looks like from outside. Clinicians misread the resemblance often enough that the review names the consequence: social anxiety disorder recorded first, and the autism established years later.

Espelöer and colleagues compared 25 autistic adults, average age 38.8, with 68 adults diagnosed with social anxiety disorder and 23 with neither. The autistic group scored significantly higher than the socially anxious group on fear of speaking and fear of rejection. Their anxiety tracked intolerance of uncertainty, a difficulty with ambiguity that the review treats as an intermediate step: unfamiliar settings offer no reliable rules, the anxiety they produce leads to avoidance, and avoidance removes the practice by which social skill is acquired.

A Swedish group led by Sofia Bejerot put a similar comparison to 50 autistic adults, 100 adults with social anxiety disorder and 53 with neither. Social anxiety was high in both clinical groups, and the accounts behind it diverged. The adults with social anxiety disorder judged themselves socially incompetent while acknowledging adequate skills; the autistic adults had genuine difficulty with those skills and less insight into how they were perceived. Missing insight of that kind, the authors suggest, can leave an autistic person reporting less anxiety than their circumstances would predict.

The overlap invites a deflationary reading, that the two conditions share questionnaire items and any correlation is the sound of one question asked twice. Stark, Groves and Kofler examined that possibility in a secondary analysis of 194 children aged 8 to 13, published in the British Journal of Clinical Psychology in 2023. Reduced social competence emerged as a risk factor for social anxiety in children with elevated autism symptoms, and the relationship did not reduce to item overlap.

What it means for you and your child

Withdrawal in an autistic child is easily assigned to the autism, on the reasonable ground that difficulty with other people is what the diagnosis describes. The material here makes that assignment less safe than it looks. Social anxiety in autism has contributors the review can name, and in the one study to test whether the association is an artefact of measurement, it survived the test.

The confusion runs in the other direction at least as often. The review’s stated concern is the clinician who records social anxiety disorder in a person whose difficulty is autistic, delaying recognition of the autism by years. Watching the child settles neither question.

Cognitive ability offers no shelter. The review reports that more cognitively able adolescents with autism are more likely to be socially anxious, attributed to a sharper awareness of their own difficulty, and in a pilot study of 15 autistic adolescents and 18 without autism, White and colleagues found self-reported fear of negative evaluation associated with longer gaze toward social threat cues. A child articulate enough to describe what went wrong at lunchtime carries that description into the next lunchtime.

The quieter case runs on the same logic. A child who reports no distress about school may be reporting accurately, or may have limited access to how others read them, which Bejerot’s group offers as one explanation for autistic adults who report less anxiety than expected.

Ten papers is a thin base, and the authors say so. No study among the ten compared which features of autism generate the most anxiety, and non-English publications were excluded. Several of the ten studied adults in their thirties, so the bearing of those findings on an eleven-year-old is inference rather than result. No treatment trial appears in the set, which makes the closing call for better intervention a recommendation rather than a finding.

What follows for a parent is a question rather than a label. Whether the fear a child shows before a party or a presentation has ever been assessed in its own right, and by whom, is answerable at an appointment.

The criteria for autism describe difficulty with reciprocal conversation and with reading a face, and dread of being watched while speaking appears nowhere among them. A child who can name that dread has named something a clinician can assess in its own right.
