Despite increasing attention to understanding strengths in those on the autism spectrum, few studies have explored this in older individuals. The present study provides a qualitative analysis of parent-reported strengths and positive qualities of 68 15-30-year-olds with autism and/or intellectual disability (ID). Most parents (97%) reported at least one positive quality. Themes were consistent with previous studies; Personality characteristics (82%) and Sociability (53%) were reported most frequently. A Work Ethic/Motivation category not previously reported emerged. Autistic individuals (with/without ID) were more likely than those with ID-only to have a Specific Skill. Findings highlight the importance of recognizing strengths of autistic adults. Research is needed to understand how to best leverage positive qualities to promote goal achievement and quality of life.
