Piccinin & Hofer, 2008. Integrative analysis of longitudinal studies on aging: Collaborative research networks, meta-analysis, and optimizing future studies.


As the authors describe in this chapter, numerous calls have been made for increased collaboration as a means to focus developmental research on within-person processes. The authors highlight and summarize some examples of collaborative and coordinated research, and the authors elaborate on some fundamental ideas for implementing strategies for maximizing our understanding of within person aging-related changes. The authors propose a collaborative system that encourages the evaluation and report of both parallel and alternative models on the same data as well as models incorporating individual- and study-level characteristics to account for disparities across studies. The authors believe that direct and immediate comparison and contrast of results across independent studies, based on the open availability of analysis protocol, scripts, and results, will result in the most solid accumulation of knowledge based on cross-validated evidence. This is the most powerful way to build our developmental science. (PsycINFO Database Record (c) 2018 APA, all rights reserved)
