Konzeption und Durchführung von Fokusgruppen am Beispiel des BMBF-Projekts „Übergewicht und Adipositas bei Kindern, Jugendlichen und jungen Erwachsenen als systemisches Risiko“.

Most writing on sociological method has been concerned with how accurate facts can be obtained and how theory can thereby be more rigorously tested. In The Discovery of Grounded Theory, Barney Glaser and Anselm Strauss address the equally Important enterprise of how the discovery of theory from data--systematically obtained and analyzed in social research--can be furthered. The discovery of theory from data--grounded theory--is a major task confronting sociology, for such a theory fits empirical situations, and is understandable to sociologists and laymen alike. Most important, it provides relevant predictions, explanations, interpretations, and applications. In Part I of the book, -Generation Theory by Comparative Analysis, - the authors present a strategy whereby sociologists can facilitate the discovery of grounded theory, both substantive and formal. This strategy involves the systematic choice and study of several comparison groups. In Part II, The Flexible Use of Data, - the generation of theory from qualitative, especially documentary, and quantitative data Is considered. In Part III, -Implications of Grounded Theory, - Glaser and Strauss examine the credibility of grounded theory. The Discovery of Grounded Theory is directed toward improving social scientists' capacity for generating theory that will be relevant to their research. While aimed primarily at sociologists, it will be useful to anyone Interested In studying social phenomena--political, educational, economic, industrial-- especially If their studies are based on qualitative data.

"Showing how science is limited by its dominant mode of investigation, Lincoln and Guba propose an alternative paradigm--a "naturalistic" rather than "rationalistic" method of inquiry--in which the investigator avoids manipulating research outcomes. A "paradigm shift" is under way in many fields, they contend, and go on to describe the different assumptions of the two approaches regarding the nature of reality, subject-object interaction, the possibility of generalization, the concept of causality, and the role of values. The authors also offer guidance for research in the field (where, they say, naturalistic inquiry always takes place). Useful tips are given, for example, on "designing" a study as it unfolds, establishing "trustworthiness," and writing a case report. This book helps researchers "both to understand and to do naturalistic inquiry." Of particular interest to educational researchers, it is valuable for all social scientists involved with questions of qualitative and quantitative methodology."--Publisher's description.
