Scaling is a convenient and equipment-free means for speech-language pathologists (SLPs) and clients to evaluate stuttering severity in everyday situations. This study investigated the extent to which the severity ratings of 10 adult stuttering speakers, made immediately after speaking and again from recordings 6 months later, agreed with ratings made by an SLP. For 9 of the 10 speakers, there was good agreement between their initial ratings and those of the SLP. For 8 of the 10 speakers, there was also good agreement between their initial ratings and those made from recordings 6 months later, indicating that the severity ratings made at the time of speaking were reliable. These findings support the use of the 9-point scale as a clinical measurement procedure.
