This article reports the results of an examination of the endorsement, reliability, and factorial validity of the VIA--Youth and assessment of character strengths and virtues developed for the general population in youth with and without intellectual disability. Findings suggest that, generally, youth with intellectual disability endorsed character strengths as being like them at lower levels, although few differences were significant. Issues related to measurement, particularly the establishment of measurement invariance, emerged for some virtues. Reliability of the scale was similar across the two groups. Implications for future research and practice are discussed.
