Abstract
LEGO(®)-based therapy is a social skills development program aimed at children with autism spectrum disorder (ASD). A systematic review of the literature was conducted using PRISMA guidelines. PubMed, Scopus and Web of Science bibliographic databases were searched from their date of inception to August 2020. The review included 19 studies. Studies were classified according to experimental designs (e.g., Randomized Control Trial, Non-Randomized Studies of Interventions and case report and series) and a narrative synthesis of each was provided, along with a critical discussion of the strengths and weaknesses of the available literature on the topic. Although LEGO(®)-based therapy appears a promising treatment for social interaction in ASD, the findings of LEGO(®)-based therapy studies should be interpreted and generalized with caution, due to the low quality of the studies and the small sample sizes.
