Three Adolescents, Fifteen Weeks

What the research found

This 2023 study tested a training programme the authors call ToM-SS, short for Theory of Mind and Social Skills. Theory of mind is the everyday ability to work out what another person is thinking, feeling, or wanting. Many autistic people find this harder than their peers do, and the researchers wanted to know whether it could be taught directly, alongside practical social skills, to autistic adolescents.

The first thing to be clear about is the size and shape of the study. It followed three teenagers, aged 12, 17, and 18. All three met the DSM-5 diagnostic criteria for autism and had measured IQ scores between 50 and 70. This is not a large trial with a treatment group and a comparison group. It is what researchers call a single-case experimental design: each young person is observed closely over time and effectively serves as their own point of comparison. Behaviour is measured during a baseline period, then during the intervention, then afterwards, and the question is whether change tracks the arrival of the training rather than the passage of time.

The training itself was intensive and structured. Each adolescent had one-to-one sessions four times a week for fifteen weeks, roughly 35 minutes at a time, running from September to December 2019. The theory-of-mind lessons covered ideas such as “seeing leads to knowing” and reading emotions from a person’s desires or their situation. The social-skills lessons were practical: praising others, expressing emotion, and asking for help. Teaching was delivered with printed cards, pictures, and short social videos.

On the study’s own measures, all three improved. A theory-of-mind test scored out of a possible maximum rose in every case: from 3 to 10 for the first participant, from 0 to 8 for the second, and from 4 to 10 for the third. Accuracy on the specific target social behaviours reached above 90 per cent by the end. The researchers also used the Social Responsiveness Scale, a questionnaire where higher scores mean more social difficulty, so a fall is an improvement. The three teenagers’ scores dropped from 78 to 71, from 80 to 73, and from 84 to 78. The gains were still present at follow-up.

The measurement was conducted carefully. Two observers agreed on what they were seeing between 95.5 and 97.5 per cent of the time, and the programme was delivered as designed on the checks that were run. That care matters, because in a small study it is the main thing standing between a real effect and wishful thinking.

What it means for you and your child

The honest headline is that a well-designed programme produced clear, measurable improvements in three autistic adolescents, and that is genuinely encouraging. Theory of mind was long thought to be relatively fixed. Here, direct teaching moved it, and the practical social skills moved with it and held afterwards. For a parent, the useful message is that these abilities are trainable, not simply fixed traits a child either has or lacks.

It is just as important to be clear about what three young people cannot tell us. With a sample of three, we cannot know how many other autistic adolescents would respond the same way, or which ones. All three had IQ scores in a specific range, so the findings say little about children who are very different. A single-case design can show that change followed the training closely, which is a real strength, but it cannot rule out every other explanation as confidently as a large controlled trial can. This study is a promising signpost, not a settled conclusion.

The authors themselves are candid about the limits, and their honesty is worth trusting. They note the small sample. They point out that the Social Responsiveness scores came from teachers, whose judgements are inevitably somewhat subjective. They flag that they had limited data on whether the new skills carried over into settings beyond the structured lessons. And they acknowledge that the whole programme was run by researchers in a classroom, which is not the same as a busy family home or a school playground. Improvement in a controlled room does not automatically become improvement in the messier places where social life actually happens.

So what should this change in practice? Not very much on its own, and that is the point. If your child is already receiving structured social-skills support, this study offers modest reassurance that the underlying skills can shift with focused, repeated, one-to-one teaching. The intensity here is notable: four sessions a week for fifteen weeks is a serious commitment, and the results should be read in that light rather than as evidence that a lighter touch would do the same.

The sensible response is interest without over-reading. One small, careful study of three adolescents is exactly the kind of work that should prompt larger trials, and until those exist, any claim that this programme reliably improves social competence in autistic teenagers as a group is running ahead of the evidence. Treat it as an early, promising result, discuss any structured intervention with the professionals who know your child, and be wary of anyone selling certainty that three participants cannot support.
