Conclusion

Longitudinal studies can be extremely useful for understanding measurement and classification for disorders that change over time. They provide information on outcomes, change over time, intercepts, rate of change, the patterns of change, predictors of change, and outcomes associated with change. In designing studies, the value of adding a data point in time is not fully appreciated, but it is also very important to be clear about the questions being asked and the underlying assumption of the model, particularly with respect to the question of homogeneity or heterogeneity of development. Perhaps by better appreciating developmental diversity among disorders that begin in childhood or adolescence, we can derive a measurement and classification system that has optimal clinical utility.
