The Michigan Alcoholism Screening Test and its shortened form: a meta-analytic inquiry into score reliability.
Meta-analytic methods provide a framework around which an inquiry into MAST and SMAST score reliability was completed. Of the 470 measurement opportunities observed between 1971 and 2005, 62 (13.2%) were coupled with accurate reliability information. Weighted reliability estimates centered on .80 suggesting that the MAST and SMAST generally produce scores of similar and adequate reliability for most research purposes. However, the variability of internal consistency estimates shows that at times these tools will not produce reliable scores, particularly among female and nonclinical respondents. Multiple regression equations provide practical guidelines to improve reliability estimates for the future use of these instruments.
