Summary
This completed trial tested whether LEGO therapy can improve social skills in 50 adolescents aged 10–14 with high-functioning autism. Participants attended 12 weekly 90-minute group LEGO sessions over 3 months. Researchers compared their social skills to a control group who continued usual treatments, using questionnaires and tasks at the start and end of the study.
