Percentile norms calculator

Large scale normative data have recently been provided for the MDAS based on a sample size of 10,990 participants. See MDAS_associated_references (Word, 51 KB). For clinicians and researchers a convenient means of scoring an individual’s MDAS score is via a computer program that can be downloaded (or run) from this page. The program is for PCs but will run on a Mac provided that suitable emulation software is installed.
