The first aim of this study was to examine the Japanese Checklist for Possible Cluttering ver.2 (JCPC ver.2) for children who stutter (CWS), and to validate the items that construct JCPC ver.2 for the definitive differentiation of stuttering from cluttering. The second aim was to estimate a norm score for distinguishing stuttering and cluttering using JCPC ver.2. The third aim was to propose a draft version of JCPC ver.3, provided any item elimination was suggested through the validation process. In this study, the utility of JCPC ver.2 was examined in 237 CWS. Study results identified three factors including disorganized speech/language output related items, inattention and dyssynchrony related items, and poor language planning related items. These three identified factors were related to the language automatization deficit model (van Zaalen & Reichel, 2015). As four items showed low factor loading that was below 0.30 after a Varimax rotation, they were removed from JCPC ver.3 (draft). A more sensitive version of the JCPC checklist is required in future to differentiate cluttering from stuttering.
