Abstract
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. Analyses were performed using three taxometric procedures: mean above minus below a cut (MAMBAC), maximum eigenvalue (MAXEIG), and latent mode factor analysis (L-Mode). 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. 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.
