Multiple published reports were utilized to calculate RCI values for the CDRS-R. Specifically, the standard deviation of the assessment is derived from a larger sample of similar aged participants to the current sample (Emslie et al., 2008); while alpha was not available for the full sample, it was available from 12 to 16 year olds in the same sample (Mayes et al., 2010).
