People with autism spectrum disorder (ASD) have an increased risk of suicidality. However, the risk factors remain under-investigated. This study explored factors that increase suicidality risk in ASD. Through an online survey, 150 adults with ASD were compared to 189 control adults. Autistic traits, depressive symptomatology, alexithymia, and antidepressant intake were assessed on their contribution predicting suicidality. Among people with ASD, 63% scored above the cutoff for high suicidality risk. Increased autistic traits, depressive symptomatology, and antidepressant intake significantly predicted suicidality. Furthermore, among those with high levels of autistic traits, the risk of suicidality was increased if they also had high levels of alexithymia. These results highlight the importance of considering depression, antidepressants, and alexithymia to prevent suicidality in ASD.

The aim of the present study was to assess the usefulness of QTrobot, a socially assistive robot, in interventions with children with autism spectrum disorder (ASD) by assessing children's attention, imitation, and presence of repetitive and stereotyped behaviors. Fifteen children diagnosed with ASD, aged from 4 to 14 years participated in two short interactions, one with a person and one with the robot. Statistical analyses revealed that children directed more attention towards the robot than towards the person, imitated the robot as much as the person, and engaged in fewer repetitive or stereotyped behaviors with the robot than with the person. These results support previous research demonstrating the usefulness of robots in short interactions with children with ASD and provide new evidence to the usefulness of robots in reducing repetitive and stereotyped behaviors in children with ASD, which can affect children's learning.

Children with autism spectrum disorder (ASD) have more emotional difficulties than typically developing (TD) children. Of all the factors that impact children's emotional development, parents, and the way they interact with their children, are of crucial importance. The present study compared the amount of parent–child interactions among 35 dyads of parents and their children with ASD and 41 dyads of parents and their TD children, aged between 3 and 13 years, during a frustration‐eliciting situation. We further examined whether children's alexithymia is linked to parent–child interactions and whether parent–child interactions are linked to children's emotional difficulties. We found that parents of children with ASD interacted significantly less with their children than parents of TD children. This reduced interaction was better explained by children's alexithymia than by children's ASD diagnosis. Finally, parent–child interaction mediated the relationship between children's ASD diagnosis and children's emotion regulation ability, as well as some aspects of children's emotional reactivity but only if not accounting for children's alexithymia levels. Our results demonstrate the determinant role children's alexithymia plays on parent–child interactions and on how these interactions are linked to children's difficulties in emotion regulation and emotional reactivity. Results are discussed in light of how parent–child interactions and the emotional ability of children with ASD can be improved by targeting children's alexithymia.

Lay Summary In the present research, we found that parents of children with autism interact less with their children compared to parents of typically developing children. We also found that this decreased interaction is linked to children's difficulties to recognize, describe, and distinguish emotions, a triad of difficulties known as alexithymia. Furthermore, parents' interaction with their children explains emotional reactivity and emotion regulation problems in children with autism. However, if we take into consideration children's alexithymia, then parents' interaction with their children is not related to their children's emotional difficulties in reactivity and regulation. Therefore, to improve the interaction between parents and their children with autism, and the emotional development of these children, we recommend interventions that teach children with autism how to recognize, describe, and distinguish emotions in themselves and others.
