Aims: Archival data from structured interviews of 1193 male prison inmates were subjected to taxometric analysis to determine the latent structure of the alcohol use disorder construct. Methods: Analyses were performed using three taxometric procedures: mean above minus below a cut (MAMBAC), maximum eigenvalue (MAXEIG), and latent mode factor analysis (L-Mode). Results: The outcomes were based on three indicators: (1) DSM-IV alcohol dependence criteria 1 and 2 (tolerance/withdrawal), (2) DSM-IV alcohol dependence criteria 3, 4, and 5 and DSM-IV alcohol abuse criterion 3 (loss of control), and (3) DSM-IV alcohol dependence criteria 6 and 7 and DSM-IV alcohol abuse criteria 1, 2, and 4 (negative social/psychological consequences). The outcomes revealed consistent support for a taxonic (categorical) interpretation of alcohol use disorders. Conclusions: There may be a taxonic boundary separating those who do and do not qualify for a diagnosis of alcohol dependence or abuse with important implications for diagnosis and treatment.
