Background: Many alcohol research questions require methods that take a person-centered approach because the interest is in finding heterogeneous groups of individuals, such as those who are susceptible to alcohol dependence and those who are not. A person-centered focus also is useful with longitudinal data to represent heterogeneity in developmental trajectories. In alcohol, drug, and mental health research the recognition of heterogeneity has led to theories of multiple developmental pathways. Methods: This paper gives a brief overview of new methods that integrate variable- and person-centered analyses. Methods discussed include latent class analysis, latent transition analysis, latent class growth analysis, growth mixture modeling, and general growth mixture modeling. These methods are presented in a general latent variable modeling framework that expands traditional latent variable modeling by including not only continuous latent variables but also categorical latent variables. Results: Four examples that use the National Longitudinal Survey of Youth (NLSY) data are presented to illustrate latent class analysis, latent class growth analysis, growth mixture modeling, and general growth mixture modeling. Latent class analysis of antisocial behavior found four classes. Four heavy drinking trajectory classes were found. The relationship between the latent classes and background variables and consequences was studied. |

The Development of Heavy Drinking and Alcohol-Related Problems from Ages 18 to 37 in a U. S. National Sample Journal of Studies on Alcohol 61,2 (March 2000): 290-300.

Investigated the influence of individual background variables on the development of heavy drinking and alcohol-related problems by examining data from the National Longitudinal Survey of Youth, a general population sample (7,859 Ss) that contains information on alcohol use for the ages 18-37 yrs. Background variables included gender, ethnicity, family history of problem drinking, early onset of drinking, high school dropout, and college education. The study used a multivariate outcome approach that focused on individual variation in trajectories over age. The statistical analysis used random coefficients in a latent variable framework. Across-age changes in the importance of the influence of background variables on the outcomes were modeled using varying center points. A key finding is that dropping out of high school has no effect on alcohol-related problems for individuals in their mid-20s, but is associated with significantly increased levels of alcohol-related problems for individuals in their mid-30s. In contrast, going on to college is associated with lower levels of heavy drinking when individuals reach their late twenties and their thirties. Strong gender and ethnicity effects seen in the twenties diminish when individuals reach their thirties. ((c) 2000 APA/PsycINFO, all rights reserved) |
