Relationship between Spontaneous Speech Function and Behavior Rating Inventory of Executive Function Profile in Children with Autism Spectrum Disorders: A Pilot Case Study

Abstract

Background : Response inhibition and attentional flexibility are impaired in individuals with autism spectrum disorders (ASD). We descriptively analyzed whether differences in the functions of spontaneous speech derived from Antecedent-Behavior-Consequence (A-B-C) analysis are related to the T-scores for response inhibition (“Inhibit”) and attentional flexibility (“Shift”) of the Behavior Rating Inventory of Executive Function (BRIEF) profiles of children with ASD. Methods : Three children with ASD participated in this pilot case study. The BRIEF was used as a measure of executive function (EF). Spontaneous speech of all participants was recorded and classified into five categories: antecedent control of self (ACS), consequent control of self (CCS), antecedent control of others (ACO), consequent control of others (CCO), and exception (EXP). Results : The T-score for “Shift” of all participants exceeded a previously defined cut-off value. Spontaneous speech associated with “control of self” was not observed in any participant, while that associated with “control of others” varied among individuals. The participant with the highest frequency of spontaneous speech had the lowest “Shift” T-score, while the participant with the least active spontaneous speech had the highest “Shift” T-score. Conclusions : Our results suggest a potential association between spontaneous speech and a shift in executive function in children with ASD.
