What is Environmental Adjustment

The number of case reports of children with autism spectrum disorder (ASD) who stutter is increasing. The duration of intervention for stuttering in children with attention-deficit hyperactivity disorder (ADHD) is often greater than for children who only stutter. Whether there is a similar pattern in children with ASD who stutter should also be examined. In this study, the factors influencing the prognoses of two children with stuttering and ASD were investigated. One child's stuttering had improved and had almost been eliminated, and the other's stuttering continued. The results of the investigation showed that a significant increase in language ability and the absence of physiological problems assisted in eliminating stuttering. The child who continued to stutter originally showed a higher than average language level and high anxiety. Preventing and eliminating anxiety that accompanies ASD, in addition to intervention for stuttering, may be indispensable to reduce stuttering and improve fluency.
