Direct linkRaykov, Tenko – Measurement and Evaluation in Counseling and Development, 2009
This article outlines a readily and widely applicable procedure of reliability evaluation for scales with unidimensional measures. The method is developed within the framework of the popular latent variable modeling methodology, and it accomplishes point, as well as interval, estimation of measuring instrument reliability. The approach can be…

Evaluation of Weighted Scale Reliability and Criterion Validity: A Latent Variable Modeling Approach
Raykov, Tenko – Measurement and Evaluation in Counseling and Development, 2007
A method is outlined for evaluating the reliability and criterion validity of weighted scales based on sets of unidimensional measures. The approach is developed within the framework of latent variable modeling methodology and is useful for point and interval estimation of these measurement quality coefficients in counseling and education…
