I'm new to R, and have just found that score.alpha gives me noticeably different Cronbach's Alpha values than score.items, when using the same data frame and (as much as possible) the same options. The help page for the former says its "superseded" by the latter. Is this similar to saying that score.alpha is deprecated? Should I believe the values given by score.items instead? Darrin L.
