Abstract

Background The Cologne questionnaire on speechlessness (KFS) is the first validated instrument for the assessment of speechlessness. The empirical testing of the KFS regarding its suitability for a valid distinction between persons with low and high levels of speechlessness is a primary goal for the clinical use of the instrument. Material and methods The sample comprised the KFS data from 205 participants in an online survey. Using different inferential statistical methods, the predictive properties of the KFS item 12 were analyzed in order to make it useful for the determination of a threshold when using the KFS. Based on the 75th percentile of KFS item 12, a dichotomization of the sample was performed followed by a receiver operating characteristic (ROC) analysis of the KFS overarching total scale speechlessness. Results The results of the ROC analysis (area under the curve, AUC: 0.863; p < 0.001) revealed an optimal threshold of >29 (sensitivity 76%; specificity 79%) for the total scale of the KFS using the Youden index. Discussion The threshold for the KFS speechlessness total scale makes it possible to differentiate people with low or high levels of speechlessness. In addition, item 12 of the KFS can be used to predict potential speechlessness.
