Longitudinal Research Design

This chapter addresses longitudinal research designs’ peculiarities, characteristics, and significant fallacies. Longitudinal studies represent an examination of correlated phenomena over a period, and their analysis stresses changes over time. A longitudinal research design aims to enable or improve the validity of inferences not possible to achieve in cross-sectional research, to draw conclusions based on arguments that are not workable if we look at a point in time. Also, researchers find relevant information on how to write a longitudinal research design paper and learn about typical methodologies used for this research design. The chapter closes by referring to overlapping and adjacent research designs.
