Co-Occurring Disorders in Children Who Stutter: Analysis of Using the Japanese Checklist for Possible Cluttering

Abstract

This study aimed to investigate the rate and type of co-occurring disorders in children receiving special support for stuttering in speech and language classrooms (resource rooms and special classes for children with speech and language disorders) and compare the results of the Japanese Checklist for Possible Cluttering (JCPC) ver. 2 between the high-score and not-high-score groups. Results indicated that 27 (11.4%) of 237 children who had fluency disorder and were trained as children who stutter (CWS) were either medically diagnosed or suspected by their teachers as having co-occurring disorders. The co-occurrence of disorders was observed significantly more frequently in the high-score than not-high-score groups. The most frequent co-occurring disorders in the high-score group were “AD/HD ( N = 4),” followed by “Asperger syndrome ( N = 3),” “intellectual disability ( N = 3),” and “LD ( N = 3),” which were consist with previous studies aside from “intellectual disability.”
