The Floor Effect on the ABAS-II in Adolescents with Autism Spectrum Disorder.

The present study aimed at enhancing the assessment of adaptive behavior in adolescents with Autism Spectrum Disorder trough the Adaptive Behavior Assessment System-Second Edition. To overcome the limits underpinning floor effect, which are commonly observed with the traditional methods, the statistical Hessl method and its revision by Orsini, Pezzuti and Hulbert was adopted. The results showed a more variation using the former method compared to the latter: a greater impairment in Social versus Leisure skills emerged.
