| สรุป≠ | Comparative longitudinal research tracks two or more distinct groups across multiple time points, enabling researchers to observe how outcomes change over time and whether those trajectories differ between groups. By combining the temporal depth of longitudinal design with the between-group contrast of comparative design, this approach can detect not only whether groups differ at any single moment but also whether they diverge, converge, or evolve at different rates across the observation window. | Longitudinal research is an observational design in which the same participants, groups, or units are measured repeatedly over an extended period. Rather than capturing a single snapshot, it tracks change, stability, and temporal sequencing of variables — making it the primary non-experimental strategy for studying development, growth, decline, and the unfolding of causal processes across time. |
