The modified checklist for autism in toddlers (M-CHAT). Method: Cross-sectional data were collected from mothers of forty-five toddlers under 36 months old. Finally, we examined whether EFs deficits were predictive of RRBs. The study aimed was to investigate the relationship between EFs deficits and repetitive and restricted behaviors (RRBs) in toddlers with ASD symptoms. Future research on RRBs in ASD may benefit from focusing on specific EFs rather than general categories.īackground: Executive Functions (EFs) deficit in Autism spectrum disorder (ASD) has been mainly investigated, while less is known about the EFs in toddlers. Our results indicate a link between EFs and RRBs. Increases in EFs differences predicted an increase in RRBs.

We found significant associations between EFs and (1) stereotyped behaviors, (2) self-injurious behaviors, (3) ritualistic behaviors, (4) sameness behaviors, (5) restricted behaviors, (6) compulsive behaviors, and (7) repetitive behaviors total score. The modified checklist for autism in toddlers (M-CHAT), the Gilliam autism rating scale (GARS-2), the behavior rating inventory of executive functioning-preschool version (BRIEF-P), and the repetitive behavior scale- revised (RBS-R) administered to parents. In addition, we tested whether EFs were predictive of RRBs in toddlers.Ĭross-sectional data were collected from parents of forty-five toddlers under 36 months old.

The purpose of this study was to investigate the relationship between EFs and RRBs of toddlers with ASD symptoms. Executive functions (EFs) and restricted and repetitive behaviors (RRBs) have been studied mainly in older individuals with autism spectrum disorder (ASD), while little is known about the relationship between EFs and RRBs in toddlers.
