The volume addresses major features in empirical social research from methodological and theoretical perspectives. Prominent researchers discuss central problems in empirical social research in a theory-driven way from political science, sociological or social-psychological points of view. These contributions focus on a renewed discussion of foundations together with innovative and open research questions or interdisciplinary research perspectives.
This book explores missing data techniques and provides a detailed and easy-to-read introduction to multiple imputation, covering the theoretical aspects of the topic and offering hands-on help with the implementation. It discusses the pros and cons of various techniques and concepts, including multiple imputation quality diagnostics, an important topic for practitioners. It also presents current research and new, practically relevant developments in the field, and demonstrates the use of recent multiple imputation techniques designed for situations where distributional assumptions of the classical multiple imputation solutions are violated. In addition, the book features numerous practical tutorials for widely used R software packages to generate multiple imputations (norm, pan and mice). The provided R code and data sets allow readers to reproduce all the examples and enhance their understanding of the procedures. This book is intended for social and health scientists and other quantitative researchers who analyze incompletely observed data sets, as well as master's and PhD students with a sound basic knowledge of statistics.

Das Buch thematisiert die theoretische und empirische Bedeutung der Theorie des geplanten Verhaltens fur Sexualverhalten und AIDS-praventives Handeln. Die Theorie wird in das sozialwissenschaftliche Forschungsprogramm der rationalen Wahl (Rational Choice) integriert und mit Hilfe einer Untersuchung zum Sexualverhalten Jugendlicher und junger Erwachsener empirisch uberpruft. Die untersuchten Personen sind im Abstand von einem Jahr dreimal befragt worden. Komplexe statistische Modelle zeigen Stabilitat, Veranderung und Dynamik des theoretischen Konzeptes und geben Hinweise fur mogliche Interventionsstrategien zur Verstarkung des Praventionsverhaltens."
Dieses Buch behandelt die praktische Handhabung von Interviewer- und Befragtenverhalten auf der Grundlage von Theorien rationalen Handelns. Neben der Einfuhrung in die Thematik gibt der erste Teil des Buches einen Uberblick uber die theoretischen Ansatze zum Interviewer- und Befragtenverhalten sowie eine soziologisch-theoretische Integration dieser Ansatze. Der zweite Teil widmet sich den Verzerrungsursachen von Befragungsergebnissen. Im dritten Teil werden mit Hilfe einer mundlichen Befragung systematisch Einflusse von sichtbaren und nichtsichtbaren Merkmalen von Tendenzen zur sozialen Erwunschtheit auf das Antwortverhalten untersucht. Abschliessend werden die empirischen Ergebnisse mit den theoretischen Ansatzen konfrontiert, Mess- und Operationalisierungsprobleme dargelegt sowie praktische Kosequenzen fur die empirische Sozialforschung genannt."
