Test–retest reliability and practice effect of the Leuven Perceptual Organisation Screening Test

Abstract: Visual diagnostic tests must have a high degree of consistency in their measurements (high reliability) to ensure accurate assessment of perceptual abilities. The current study assessed test–retest reliability and practice effects in the Leuven Perceptual Organisation Screening Test (L-POST) in 144 healthy volunteers, with time intervals between 0 and 756 days. We used Pearson's and intraclass correlation analysis, Bland–Altman analysis and multilevel modelling. Results from our analyses converged and supporte… Show more

“…We use 30 samples from the output of the proposed system and body thermometer to show the measurement performance of each tool. In each measurement sample, we use the same person and environment to keep the consistency of testing [25], [26]. The comparison result is shown in Fig.…”

“…If a construct is measured twice under identical conditions, the absolute difference between the two measurements will, in 95% of cases, be smaller than the repeatability coefficient, and thus the lower this coefficient is, the greater reproducibility of the survey results (Vaz et al, 2013). A value identifying a tolerable level of mean difference for the Bland-Altman test must be not in excess of one-third of the possible range of scores for the instrument (Ding & Vancleef, 2022). Given that the GIPSS is composed of 22 items with a five-point response option, the potential sum of points lies between 22 and 110.…”
