The Association Between Social Skills and Mental Health in School-Aged Children with Autism Spectrum Disorder, With and Without Intellectual Disability.

Ratcliffe et al. (2015) asked parents and teachers to rate 292 children aged 6-13. All kids had autism; some also had intellectual disability.

The team looked at social-skills scores and mental-health checklists. They wanted to know if weaker social skills predicted bigger mental-health problems.

Children with the lowest social-skills scores had the highest anxiety, sadness, and behavior problems.

The link stayed strong whether or not the child also had intellectual disability.

Capio et al. (2013) saw the same pattern: poorer social ties forecast higher anxiety in a large ASD sample.

Harkins et al. (2023) later showed the link still holds for older autistic boys.

Two adult studies seem to disagree. Porter et al. (2008) and Tsakanikos et al. (2006) found no extra mental-health risk in adults who have both autism and ID. The gap is about age: kids feel the social pinch harder than grown-ups with stable routines and controlled settings.

If social skills are this powerful, every IEP team should list social goals as mental-health prevention. Start friendship groups, peer modeling, or lunch-bunch clubs now. Track both social growth and anxiety checklists; when one moves, the other usually follows.
