[R-sig-teaching] Cronbach's Alpha Values

[Jeremy Miles]

Almost always that you've made a mistake and haven't reversed some items
that should have been reversed. (Some software will do that automatically).

Use check.keys=TRUE, and the alpha function (in the psych package) will
automatically reverse items if that needs to be done.
