The visual analogue scale (VAS) and Likert scale (LS) are widely used but the patients might have difficulties to work with these scales and there might be errors in calculation. Huber, J F HГѓВјsler, J Zumstein, M D Ruflin, G LГѓВјscher, M For FA, maximum likelihood and weighted least squares estimations using Pearson correlation matrices among items are compared. This study compares the performance of two approaches in analysing four- point Likert rating scales with a factorial model: the classical factor analysis (FA) and the item factor analysis (IFA).

Among radiologists with different levels of experience, there were significant differences in these cancer detection rates. The detection rates of overall cancer and CSPC strongly correlated with the five-point grading of the Likert scale. By comparison, in Likert 4-5 lesions, significant differences were noted in overall cancer detection rate (63% vs 35% P = 0.001) and CSPC detection rate (47% vs 29% P = 0.027) for the more experienced vs the less experienced radiologists. Grading using the five-point scale showed strong positive correlation with overall cancer detection rate (r = 0.949, P = 0.05) and CSPC detection rate (r = 0.944, P = 0.05). For Likert scores 1-5, the overall cancer detection rates were 12%, 13%, 22%, 50% and 59%, respectively, and the CSPC detection rates were 4%, 4%, 12%, 33% and 48%, respectively. The median patient age was 64 years, PSA level 6.97 ng/mL and estimated prostate volume 52.2 mL. All lesions with Likert scores 1-5 were prospectively defined as targets for MRI/US FTB. 3-Tesla MRI was independently reported by one of eight radiologists with varying levels of experience and scored on a five-point Likert scale. We retrospectively reviewed 1218 MRI-detected lesions in 629 patients who underwent subsequent MRI/US FTB between October 2012 and August 2015. To evaluate the accuracy of a magnetic resonance imaging (MRI)-based Likert scoring system in the detection of clinically significant prostate cancer (CSPC), using MRI/ultrasonography (US) image-fusion targeted biopsy (FTB) as a reference standard.

This study compared the Type I and II error rates of the 't' test versus the Mann-Whitney-Wilcoxon (MWW) for five-point Likert items. Likert questionnaires are widely used in survey research, but it is unclear whether the item data should be investigated by means of parametric or nonparametric procedures.
