For k = 10 and r ˉ = 0.60, we obtain α s = 0.94, which is the value of standardized alpha corresponding to either group of 10 items in the scenario of Question 3. The average correlation between the 20 items in this scenario is 0.284.

WebThe internal consistency (Nunnally 1978) was measured by Cronbach’s α. To estimate intrarater reliability (Hobart et al. 1996), three evaluators were shown the videotapes of the baseline assessments of 20 of their patients more than one year after the assessments and were asked to rescore the QMFT.
