An Exploration of Online and In-Person Administration of the Kaufman Brief Intelligence Test, Second Edition (KBIT-2) in Children and Adolescents Being Evaluated for Autism Spectrum Disorder.

ABSTRACT

PURPOSE:  Most assessment tools used to diagnose and characterize autism spectrum disorder (ASD) were developed for in-person administration. The coronavirus disease 2019 (COVID-19) pandemic resulted in the need to adapt traditional assessment tools for online administration with only minimal evidence to support validity of such practices. METHODS: The current exploratory study compared scores from online administration of the Kaufman Brief Intelligence Test, Second Edition (KBIT-2) during the pandemic to scores derived from follow-up testing using traditional in-person administration. Participants were 47 children and adolescents (M age = 9.48 years, SD = 4.06; 68.10% male) who participated in a telehealth diagnostic evaluation for ASD that included online administration of the KBIT-2. Participants were invited to complete the KBIT-2 a second time during an in-person study visit. RESULTS: Pearson's correlation coefficients suggested acceptable to good reliability between online and in-person administration. Although most participants' online and in-person scores were within one standard deviation of each other, results suggested statistically significant differences between scores derived from the two modalities. Additionally, 19-26% of participants (depending on domain examined) had scores that differed by more than one standard deviation. Notably, all but one of these participants was under the age of 12 years. CONCLUSION: Findings suggest that online administration of the KBIT-2 is likely appropriate for older children and adolescents with ASD. However, additional research is needed to test online administration of intellectual assessments for children with ASD.
