Emotion regulation, emotionality, and expression of emotions: A link between social skills, behavior, and emotion problems in children with ASD and their peers.

This study aimed to investigate differences between emotion regulation (ER), emotionality, and expression of emotions in children with Autism Spectrum Disorder (ASD) and their typically developing (TD) peers; and to examine the potential links between these areas of development with social skills in both groups, as well as with behavioral, emotional, and social problems in ASD. Forty-four children (40 males and 4 females, ages 3 to 7 years) with ASD (n = 22) and their TD peers (n = 22) were included in this study. Mothers reported about their children's ASD symptoms, social, emotional, and behavioral functioning. As predicted, children with ASD were described as showing decreased ER, increased emotionality, and decreased expression of emotions when compared to their TD peers. Moreover, in the ASD group, increased social skills were associated with enhanced ER and increased expression of emotions; and in the TD group, increased social skills were correlated with decreased emotionality. Finally, enhanced ER was linked to decreased peer problems, and increased prosocial behaviors; and decreased emotionality was linked to decreased behavior and emotional problems in the ASD group. Implications for further research are discussed. Published by Elsevier Ltd.
