DOI: 10.1037/met0000132
Abstract: Abstract The most widely used, general index of measurement precision for psychological and educational test scores is the reliability coefficient—a ratio of true variance for a test score to the true-plus-error variance of the score.… read more here.

DOI: 10.1177/0013164417713570
Abstract: In applications of item response theory (IRT), an estimate of the reliability of the ability estimates or sum scores is often reported. However, analytical expressions for the standard errors of the estimators of the reliability… read more here.

DOI: 10.1177/01466216221084210
Abstract: Recent work on reliability coefficients has largely focused on continuous items, including critiques of Cronbach’s alpha. Although two new model-based reliability coefficients have been proposed for dichotomous items (Dimitrov, 2003a,b; Green & Yang, 2009a), these… read more here.
