Abstract
The aim of this project was to determine whether the use of anchors improves interrater and intrarater reliability when nonexpert listeners rated five features salient to hypokinetic dysarthria: overall severity, reduced loudness, articulatory imprecision, short rushes of speech, and monotony. Fourteen nonexperts rated 82 sentences recorded from individuals with Parkinson's disease and healthy controls using five separate equal appearing interval (EAI) scales to indicate their perception of the five features mentioned above. The listeners rated the samples twice, once without and once with external anchors. Interrater reliability and intrarater reliability were calculated using intraclass correlation coefficients (ICCs). Findings revealed an overall increase in both interrater and intrarater reliability for most features in the anchor condition, except for monotony, where a decrease in single-measures ICC was noted for the anchor compared to non-anchor condition. These preliminary findings highlight how external anchors can benefit interrater and interrater reliability when rating perceptual dimensions of dysarthria.
