ASD children are characterised by their refusal to change and difficulty in changing their responses to different social situations, which make it difficult for them to communicate with others, including their parents. We applied the comprehensive care technique Humanitude™ to mothers of children with ASD to support them from a multimodal communication perspective. Changes in mother-child communication were analysed in terms of mother-child gaze and the time the mother-child spent playing together. The results indicate that after the intervention with Humanitude™, there were significant differences in eye contact, mothers looking at their children, and children looking at their mothers. There was also a decrease in the amount of time children spent playing alone was found. There was a high correlation between pre and post-Humanitude™ intervention in the amount of time both mothers and children spent looking at each other, which suggests that incorporating multimodal communication can affect communication between parents-children.
