WebI computed Cronbach's alpha treating all items as a single scale (alpha was about 0.6) and deleting one item at a time (max alpha was about 0.72). I know that alpha can be underestimated and overestimated depending on the number of items and the dimensionality of the underlying construct. So I also performed a PCA. WebDescription. Cronbach’s alpha is an estimator of test reliability that is suitable for use in single applications of a test, typically in cross-sectional designs. Given a test composed of p items, Cronbach’s alpha assumes that all items are equivalent test units and corresponds to the reliability of the full test computed by extending the ...
