Reliability alpha cronbach
WebThe reliability of the QCD was examined by Cronbach’s alpha, which assessed the internal consistency of the questionnaire. Concurrent criterion validity of QCD scores was examined by Spearman’s correlation of QCD with SNAP-IV and WFIRS-P scores. Results: A total of 200 Chinese patients were analyzed (average age, 10.4±2.66 years). WebCronbach’s alpha is a statistical measure. It is generally used as a measure of internal consistency or reliability of a psychometric instrument. In other words, it measures how well a set of variables or items measures a single, one-dimensional latent aspect of individuals.
