Three (or More) Alcohol-Dependence Symptoms but Not Clustered in the Same 12 Months: Diagnostic Orphans From a Longitudinal Perspective

Littlefield, Andrew K.; Verges, Alvaro; Sher, Kenneth J.

Abstract

Objective: The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), currently uses a polythetic classification system for defining alcohol use disorders (AUD; alcohol abuse and dependence). This classification results in individuals who are subthreshold for an official AUD diagnosis but still endorse one or two criteria of dependence: so-called "diagnostic orphans." To our knowledge, however, there has been no attention given to diagnostic orphans from a lifetime perspective. The goal of the current article was to compare various diagnostic groups based on lifetime reports of abuse and dependence symptoms on a range of outcomes. Method: Data taken from the National Epidemiological Survey of Alcohol and Related Conditions study were used to form seven mutually exclusive diagnostic groups based on lifetime abuse and dependence symptomatology. Results: Diagnostic groups that experienced extensive dependence symptoms, regardless of past-12-month clustering (i.e., formal diagnostic criteria), tended to exhibit poorer outcomes compared with participants that met formal lifetime diagnosis for an AUD through abuse alone. It is notable that a significant group of individuals who failed to meet formal lifetime AUD diagnosis, but who endorsed a number of dependence symptoms, consistently demonstrated more problematic outcomes on a range of measures compared with individuals who never reported dependence symptoms but who were formally diagnosed with lifetime AUD through alcohol abuse. Conclusions: DSM-IV lifetime diagnostic criteria may exclude individuals with a history of extensive dependence symptomatology. Implications regarding lifetime diagnosis conceptualization are discussed. (J. Stud. Alcohol Drugs, 71, 864-869, 2010)
