A Step-by-Step Guide to Using Secondary Data for Psychological Research

The purpose of this paper is to serve as a primer for those who have never used, or even considered using, secondary data as a resource for psychological research. Secondary data (SD) can provide a unique methodological tool with which to examine psychological issues and can serve as a valuable contribution to a program of research. However, this important resource may often be overlooked because its use can sometimes appear daunting and time-consuming. We seek to assist new users of SD by describing the process in a step-by-step manner. We address both benefits and challenges to anticipate when using SD, and discuss identifying and acquiring potential datasets, creating a personalized dataset, variable creation, statistical considerations, and the potential problem of conflicting findings when large datasets are used by multiple researchers. Our goal is to encourage researchers who are novices to the approach to consider using SD as an adjunct to their program of research.
