Purpose The aim of this study was to examine the psychometric properties of the C hinese version of the M ichigan A lcoholism S creening T est ( 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.
