Characterizing Alcohol Dependence: Transitions during Young and Middle Adulthood Experimental and Clinical Psychopharmacology 14,2 (2006): 228-244. Also: https://doi.org/10.1037/1064-1297.14.2.228 Cohort(s): NLSY79 Publisher: American Psychological Association (APA) Keyword(s): Alcohol Use; Transition, Adulthood Community and high-risk sample studies suggest that alcohol dependence is relatively stable and chronic. By contrast, epidemiological studies demonstrate a strong age-graded decline whereby alcohol dependence tends to peak in early adulthood and declines thereafter. The authors identified the latent trajectory structure of past-year alcohol dependence to investigate (a) whether the syndrome is characterized by symptom profiles and (b) the extent to which the syndrome is stable and persistent. Data from current drinkers (N = 4,003) in the National Longitudinal Survey of Youth were analyzed across two waves: 1989 (ages 24-32 years) and 1994 (ages 29-37 years). Three classes of alcohol dependence were observed; symptom endorsement probabilities increased across successively severe classes. Latent transition analyses showed high rates of stability, supporting alcohol dependence as a relatively chronic condition. Although there was evidence of progression to more severe dependence, there was greater syndrome remission. Trajectory classes and transition probabilities were generalizable across race and sex and, to a lesser extent, age cohort and family history of alcoholism.

Dimensionality of Alcohol Dependence in Young Adulthood: Current versus Lifetime Symptomatology Journal of Studies on Alcohol 64,4 (July 2003): 495-500.

Objective: The factor structure of alcohol dependence was investigated using exploratory factor analysis, specifically contrasting models of alcohol dependence based on lifetime symptom endorsement to models based on current (i.e., past-year) symptom endorsement. Method: Data from the 1989 National Longitudinal Survey of Youth were analyzed. DSM-IV alcohol dependence was assessed in this large community sample of current drinkers and lifetime drinkers, representative of both men and women, and ranging in age from 24 to 32. Sixteen items assessing the seven criteria of DSM-IV alcohol dependence were employed. Results: A single-factor model accounted for most of the observed relationships. However, evidence of additional dimensions, characterized by tolerance and impaired control symptoms, was also identified. Conclusions: Our findings do not support the historical tendency of distinguishing physiological (as indicated by tolerance or withdrawal symptoms) from nonphysiological dependence. Most importantly, factor solutions derived from items based on past-year symptom endorsement were consistent with those derived from items based on lifetime symptom endorsement in samples of both current drinkers and lifetime drinkers.
