AbstractMany social gerontologists have been involved lately in correlational and/or comparative research activities to advance their professional knowledge and explore social facts and realities about the aging world. Conducting this kind of research requires social gerontologists to pay proper attention to the formation of comparison groups and to the explanation of findings. They have to deal with the issue of validity so as to obtain empirical knowledge, develop theories, and test hypotheses. According to Campbell and Stanley, there are two kinds of validity: internal and external. This original concept of validity provides a framework for us to critically identify the methodological problems of a correlational, comparative study, and to determine the degree to which this particular research design meets the validity requirements. This article concludes that social gerontologists must control as many internal and external validity threats as possible in order to develop scientific knowledge and generalize their findings. They should make sure that their samples are probabilistically obtained when conducting comparative studies. In addition, statistical findings and conclusions must be supported by intellectual and/or culturally relevant explanations. © 2008, Hallym Aging Research Institute, Hallym University.
