In particular the ability of ESD and EIS scores to produce consistent scores overtime in a stable patient population (test-retest reliability), the extent to which ESD and EIS scores reflect scores for other PROs measuring similar/dissimilar concepts (concurrent validity), are able to discriminate between groups according to key indicators e.g
