Feedback:
An instrument is internally consistent to the extent that its items measure the same trait. Internal consistency reliability is the best way to assess an important source of measurement error in scales, the sampling of items. Internal consistency is evaluated by calculating coefficient alpha (Cronbach's alpha). The higher the coefficient, the more accurate (internally consistent) the measure.
