توجهات حديثة في تقدير صدق و ثبات درجات أدوات القياس : تحليل نظري تقويمي و تطبيقي

Abstract EN

Validity and reliability are two major ubiquitous issues and procedures in testing, measuring instrument design, and test standardization.

Concerning reliability, Cronbach alpha weaknesses were examined, and some recommended alternatives method for assessing reliability such as stratified alpha, composite reliability (construct reliability or Rho), and weighted omega were considered.

With regard to validity, assessment of validity through principal component - compared to factor analysis - were frequently employed, despite the fact that it is a purely a data reduction technique, and does not uncover latent structure of tests.

A more powerful method of validity assessment based on structural equation modeling that compares and select the most valid factor structure of tests among competing latent test structure models were presented and illustrated.
