Happiness, self-esteem, and prosociality in children with and without autism spectrum disorder: Evidence from a UK population cohort study.

High levels of childhood happiness, self-esteem, and prosociality are associated with positive social and emotional outcomes. In this study, we investigated whether happiness, self-esteem and prosociality co-occur in children, and how possible co-occurrence differs between those with and without Autism Spectrum Disorder. We found that for the majority of children happiness, self-esteem, and prosociality co-occur. Furthermore, although as a group children with ASD have lower levels of positive functioning, our findings suggest that nearly half of children with ASD are happy, have good levels of self-esteem, and are prosocial.
