Using Latent Growth Modeling in Program Evaluation: A Primer for the Evaluator.
Hess, Brian
Latent growth modeling (LGM) has emerged as a flexible analytic technique for modeling change over time because it can describe individual variability in terms of initial status and in growth. LGM methodology can also provide a means for testing the contribution of other variables in order to explain variability in those initial levels and growth trajectories. This paper illustrates the use of LGM as an analytical tool in program evaluation. Specifically, a hypothetical evaluation of a high school drug use prevention program was used to demonstrate: (1) how LGM methodology can be used to assess the longitudinal impact of a prevention program by comparing the treatment to a control group in terms of individual variability in initial status and rate of change; and (2) how predictors of initial status and growth selected on the basis of a particular program theory can be incorporated in the model to explain how the program produced an effect across time. Some advantages and limitations of using LGM in program evaluation are highlighted. (Contains 3 figures and 29 references.) (Author/SLD)
