This accessible book has established itself as the go-to resource on confirmatory factor analysis (CFA) for its emphasis on practical and conceptual aspects rather than mathematics or formulas. Detailed, worked-through examples drawn from psychology, management, and sociology studies illustrate the procedures, pitfalls, and extensions of CFA methodology. The text shows how to formulate, program, and interpret CFA models using popular latent variable software packages (LISREL, Mplus, EQS, SAS/CALIS); understand the similarities ...

Strukturgleichungsmodelle haben sich in den letzten Jahren zu einem Standardverfahren der Sozialforschung entwickelt. Bislang fehlt es aber an einer anwendungsorientierten Einführung für Politikwissenschaftler. Dieses Lehrbuch behandelt grundlegende Modelle zur Messung politikwissenschaftlicher Konstrukte (z.B. Fremdenfeindlichkeit), zur Schätzung von Messfehlern und zur Modellierung von Beziehungen zwischen latenten Variablen. Der Schwerpunkt liegt dabei auf der Illustration durch politikwissenschaftliche Beispiele, die durch Hinweise zur Umsetzung der Verfahren in Standardprogrammen (LISREL, Stata, MPlus) ergänzt werden.

Lauded for its easy-to-understand, conversational discussion of the fundamentals of mediation, moderation, and conditional process analysis, this book has been fully revised with 50% new content, including sections on working with multicategorical antecedent variables, the use of PROCESS version 3 for SPSS and SAS for model estimation, and annotated PROCESS v3 outputs. Using the principles of ordinary least squares regression, Andrew F. Hayes carefully explains procedures for testing hypotheses about the conditions under and the mechanisms by which causal effects operate, as well as the moderation of such mechanisms. Hayes shows how to estimate and interpret direct, indirect, and conditional effects; probe and visualize interactions; test questions about moderated mediation; and report different types of analyses. Data for all the examples are available on the companion website (www.afhayes.com), along with links to download PROCESS. New to This Edition *Chapters on using each type of analysis with multicategorical antecedent variables. *Example analyses using PROCESS v3, with annotated outputs throughout the book. *More tips and advice, including new or revised discussions of formally testing moderation of a mechanism using the index of moderated mediation; effect size in mediation analysis; comparing conditional effects in models with more than one moderat∨ using R code for visualizing interactions; distinguishing between testing interaction and probing it; and more. *Rewritten Appendix A, which provides the only documentation of PROCESS v3, including 13 new preprogrammed models that combine moderation with serial mediation or parallel and serial mediation. *Appendix B, describing how to create customized models in PROCESS v3 or edit preprogrammed models.

Alle Analysen werden an einem durchgehenden Fallbeispiel konkret und transparent durchgeführt Strukturgleichungsmodelle sind in allen Wissenschaftsdisziplinen von größter Bedeutung, da sie das Standardinstrument zur empirischen Prüfung von Hypothesensystemen darstellen. Dabei stehen oftmals die Beziehungen zwischen hypothetischen Konstrukten (latenten Variablen) im Fokus des Interesses. Das Buch zeichnet den gesamten Prozess der Strukturgleichungsmodellierung von der Konzeptualisierung theoretischer Konstrukte über die Spezifikation von Messmodellen, die Reliabilitäts- und Validitätsprüfung mittels konfirmatorischer Faktorenanalyse bis hin zur Prüfung von kausalen Wirkhypothesen mittels Kovarianzstrukturanalyse sowie PLS nach. Alle Arbeitsschritte werden an einem durchgehenden Fallbeispiel unter Verwendung von SPSS, AMOS und SmartPLS veranschaulicht und jeweils konkrete Anwendungsempfehlungen gegeben. Ebenso werden weiterführende Aspekte wie die Mehrgruppenkausalanalyse, die Spezifikation reflektiver und formativer Messansätze sowie MIMIC-Modelle einsteigergerecht behandelt.

Studierende und Forscher verschiedener Disziplinen, die am Entwickeln einer Theorie interessiert sind, stellen sich nach der Datenerhebung oft die Frage: Wie komme ich zu einer Theorie, die sich auf die empirische Realität gründet? Die Autoren beantworten diese und andere Fragen, die sich bei der qualitativen Interpretation von Daten ergeben. Auf klare und einfache Art geschrieben vermittelt das Buch Schritt für Schritt die grundlegenden Kenntnisse und Verfahrensweisen der "grounded theory" (datenbasierte Theorie), so daß es besonders für Personen interessant ist, die sich zum ersten Mal mit der Theorienbildung anhand qualitativer Datenanalyse beschäftigen. Das Buch gliedert sich in drei Teile. Teil I bietet einen Überblick über die Denkweise, die der "grounded theory" zugrunde liegt. Teil II stellt die speziellen Techniken und Verfahrensweisen genau dar, wie z.B. verschiedene Kodierungsarten. In Teil III werden zusätzliche Verfahrensweisen erklärt und Evaluationskriterien genannt.

While most books on missing data focus on applying sophisticated statistical techniques to deal with the problem after it has occurred, this volume provides a methodology for the control and prevention of missing data. In clear, nontechnical language, the authors help the reader understand the different types of missing data and their implications for the reliability, validity, and generalizability of a study's conclusions. They provide practical recommendations for designing studies that decrease the likelihood of missing data, and for addressing this important issue when reporting study results. When statistical remedies are needed--such as deletion procedures, augmentation methods, and single imputation and multiple imputation procedures--the book also explains how to make sound decisions about their use. Patrick E. McKnight's website offers a periodically updated annotated bibliography on missing data and links to other Web resources that address missing data.
