Psychometric properties of the Chinese version of the Michigan Alcoholism Screening Test (MAST-C) for patients with alcoholism.

Purpose The aim of this study was to examine the psychometric properties of the Chinese version of the Michigan Alcoholism Screening Test (MAST-C). Design & Methods The sensitivity, specificity, and positive and negative predictive values for the MAST-C were examined in this study. Findings The MAST-C had an internal consistency of 0.83 and a test–retest reliability of 0.89. It had a good content validity index of 0.92. Factor analysis identified four factors and the optimal cutoff point for the MAST-C was a score of 6/7, which yielded a sensitivity of 0.92, a specificity of 0.83, a positive predictive value of 0.92, and a negative predictive value of 0.83. Practice Implications The MAST-C provides a fast, accurate, and sensitive method for clinically diagnosing alcoholism and clinical management.
