(1992). Using adapted short MASTs for assessing parental alcoholism: Reliability and validity. Alcoholism: Clinical and Experimental Research 16, 576-584. Note: the items published in the article are specific to alcohol abuse of a parent; the items used in this script refer to oneself instead and were taken from: http://www.sh.lsuhsc.edu/fammed/outpatientmanual/Short%20MAST%2013.htm The original MAST used 25 questions and a more elaborate scoring system. It was published by: Selzer, M.L. (1971). The Michigan Alcoholism Screening Test: The quest for a new diagnostic instrument. Am J Psychiatry, 127, 1653-1658.
