“…Thus, there is little explanation for what individuals might be doing, or the activity of exploring and committing, or the potential mechanisms of these developments over time. This may be, in part, because even many of the existing longitudinal studies are not well-equipped to identify mechanisms of change due to limited time spans of study (e.g., three waves over one year, Negru-Subtirica et al, 2016), few time points of assessment (e.g., three waves over three years, van Doeselaar et al, 2020), and/or inappropriate measurements and operationalizations of identity processes based on the frequency of those measurements (e.g., attempting to measure micro-level changes of identity using macro-level measurements on a dayto-day basis, Klimstra et al, 2010b; see also Klimstra & Schwartz, 2021). In short, such designs are ill-equipped to understand mechanisms that explain the unfolding of exploration and commitment over the lengthier time frame in which identity is actually developing.…”
