Relations Between Executive Functions, Social Impairment, and Friendship Quality on Adjustment Among High Functioning Youth with Autism Spectrum Disorder.

Parents of high-functioning autistic teens filled out surveys. They rated their child's executive functions, social skills, friendship quality, loneliness, and depressive symptoms.

The researchers then used statistics to see if social problems and friendships help explain why executive-function struggles lead to feeling lonely or depressed.

Poor executive functions predicted higher loneliness and depression. Social impairment explained most of that link. Friendship quality only helped a little, and only for the path from emotional control to loneliness.

In plain words, social-skill gaps are the main bridge between thinking troubles and feeling alone or sad.

Fong et al. (2020) saw the same EF-social link in younger kids. They added a comparison group and found different EF skills matter for autistic versus typical children, so tailor your focus by age and diagnosis.

Myers et al. (2018) extended the idea downward: for elementary-age kids with ASD, metacognitive EF predicted daily living skills and behavior-regulation EF predicted depression. The pattern holds across age bands.

Ko et al. (2024) looks like a contradiction at first: in preschoolers with ASD, EF deficits explained over half of autism symptom severity. The gap closes when you note they tested direct prediction, not mediation, in much younger children.

When you see a bright autistic teen who feels lonely or down, check both social skills and emotional control. Add social-skills drills to your behavior plan and fold in self-monitoring or coping-strategy training. Strengthening friendships alone is unlikely to be enough; teach the student how to enter, maintain, and repair social interactions. The evidence now spans elementary to high school.
