Researchers have developed methods to estimate the reliability of single-item assessments, some are based on factor analysis (method FA), correction for attenuation (method CA), and others employ Molenaar and Sijtsma’s theory (method MS), coefficient λ6 (method λ6), or latent class model (method LCRC). However, no empirical study has investigated which method estimates the reliability of single-item assessment most precisely. This study investigated this question via a simulation study. To represent assessments as found in practice, the simulation study …
