Cronbach's alpha and item total correlations both provide information about how well each individual item correlates with all the other items in the measure. Cronbach's alpha is a measure of internal consistency that indicates how closely related a set of items are as a group, and item-total correlations indicate how well each item correlates with the total score on the measure. This information can be useful in evaluating the reliability and validity of a measure.
