Summary

This chapter outlines critical design decisions for longitudinal research and provides practical tips for managing such studies. It emphasizes that generative longitudinal studies are driven by conceptual and theoretical insights and describes four foundational design issues including questions about time lags and sample sizes. It then provides advice about how to manage a longitudinal study and reduce attrition. The chapter concludes by considering how the advice offered comports with recent discussions about ways to improve psychological science and providing recommended further reading.

Block’s chapter provides an insider perspective on longitudinal studies of personality and offers nine desiderata for studies.

This paper summarizes the thorny issues involved in selecting time lags for longitudinal studies.

Although it is over 25 years old, this piece provides practical advice and tips for running a large-scale longitudinal study. The advice holds for many less expansive designs as well.

This article offers a wealth of advice about reducing attrition beyond what was covered in this chapter.

Transparency and an awareness of researcher degrees of freedom are helpful for all kinds of psychological research. The guidelines in this article seem especially relevant when analyzing data from existing longitudinal studies.

This work provides an overview of the kinds of choices facing researchers and the checklist may increase awareness of p-hacking and improve the rigor of longitudinal analyses.
