The present study aims to apply a multimodal machine learning system (MMLS) in early screening for toddlers with ASD based on the RTN.

Methods: A total of 125 toddlers were recruited, including ASD ( = 61), developmental delay (DD, = 31), and typical developmental (TD, = 33).

Parents' knowledge and attitude and behavior toward autism: a survey of Chinese families having children with autism spectrum disorder.

Background: In recent years, parent-mediated intervention for children with autism spectrum disorder (ASD) has increased. Therefore, implementing effective parent training programs for parents of children with autism is of paramount importance, particularly in low- and middle-income countries. However, little is known about the status of and gaps in parents' knowledge on ASD, which may hinder the development of valid parental training programs.

The role of caregiver gestures and gesture-related responses of toddlers with autism spectrum disorder.

Autism spectrum disorder (ASD) is characterized by social communicative abnormalities. Deficits and delays in gestural communication are among the early deficits of ASD and also a major social modality in early caregiver-toddler interaction. Caregiver gestures have an important role in the cognitive and social development of children with ASD.
