L-POST reliability data of 144 health volunteers

Visual diagnostic tests must have a high degree of consistency in its measurements (high reliability) to ensure accurate assessment of perceptual abilities. The current study assessed test-retest reliability and practice effects in Leuven Perceptual Organisation Screening Test (L-POST) in 144 healthy volunteers using correlation analysis, Bland-Altman analysis, and multi-level modelling. Results from three analyses converged and supported an adequate reliability of L-POST. Additionally, multi-level modelling demonstrated an absence of practice effect, suggesting that the L-POST is suitable for repeat administration.
