Preliminary results from a meta‐analysis of drinking behavior in multiple longitudinal studies*

Abstract

This paper introduces the scope and rationale of The Collaborative Alcohol-Related Longitudinal Project and describes the individual longitudinal studies which contribute to this large collaborative project, representing studies from 15 countries. It also serves as an introduction to four reports of the preliminary findings from the project. The project is distinguished by (1) its interdisciplinary research approach which has assembled a multidisciplinary group of scholars to direct and interpret analyses, (2) its use of primary data from multiple longitudinal studies, (3) the parallel analyses of primary data from multiple studies, using comparable measures across studies recorded to a standard format and common analytic model, and (4) its use of meta-analysis to combine results across studies. Its research objectives include determining the cross-study consistency of findings of (1) the incidence and chronicity of drinking patterns and problems, (2) exogeneous factors which initiate and alter drinking careers, (3) socio-behavioral factors measured in childhood and adolescence which predict adult drinking problems, (4) inter-generational biological and social factors which predict adult drinking problems, and (5) aggregate-level factors which account for study differences. The method of sampling of studies from the world's alcohol-related general population longitudinal research is described.
