WebJan 1, 1991 · The term ‘internal consistency’ has been used extensively in classical psychometrics to refer to the reliability of a scale based on the degree of within-scale item intercorrelation, as measured by say the split-half method, or more adequately by Cronbach's (1951) (Psychometrika, 16, 297–334) alpha, as well as the KR 20 and KR 21 coefficients. WebFeb 25, 2016 · 2) Note also that average inter-item correlations are directly related to the standardized Cronbach's alpha which is considered mostly as a "reliability" index. 3) In my own opinion "internal consistency" is a bad term. I would rather use concepts "item-total (or item-construct) homogeneity" (a facet of validity) and "item-item homogeneity" (a ... WebInter-item correlations address issues relating to a scale's fidelity of measurement, how well the instrument is measuring some construct (e.g., its internal consistency, Cronbach, 1951). Finding the judicious blend of overlap and diversity is the key issue to consider when examining correlational overlap among items (Allen & Yen, 2002 ). tena durrani wikipedia
