There are two ways to organize factors in Bronfenbrenner’s Process–Person–Context–Time (PPCT) model using quantitative data: a latent growth curve model with a moderation variable and a mediation model. This study’s objectives are to examine these ways, discuss whether they meet some of the necessary criteria based on the definition of the elements and the theory propositions, and consider the advantages and disadvantages of each model. The analysis will help researchers to decide which model to use in different situations.
