PSYRATS Voices Subscale - has anyone calculated a reliable change index for this?

13 June 2018 0 693 Report

Hi folks

I have tried to obtain Chronbach's Alpha/Test-Retest Reliability and the Standard Deviation of the same sample in published papers to calculate the RCI for people who hear voices, but cannot find both in the same paper(s).

Has anyone been able to calculate the RCI for the above?

Many thanks in advance,

James
