Multilevel modelling is a data analysis method that is frequently used to investigate hierarchal data structures in educational, behavioural, health, and social sciences disciplines. Multilevel data analysis exploits data structures that cannot be adequately investigated using single-level analytic methods such as multiple regression, path analysis, and structural modelling. This text offers a comprehensive treatment of multilevel models for univariate and multivariate outcomes. It explores their similarities and differences and demonstrates why one model may be more appropriate than another, given the research objectives. New to this edition: An expanded focus on the nature of different types of multilevel data structures (e.g., cross-sectional, longitudinal, cross-classified, etc.) for addressing specific research goals; Varied modelling methods for examining longitudinal data including random-effect and fixed-effect approaches; Expanded coverage illustrating different model-building sequences and how to use results to identify possible model improvements; An expanded set of applied examples used throughout the text; Use of four different software packages (i.e., Mplus, R, SPSS, Stata), with selected examples of model-building input files included in the chapter appendices and a more complete set of files available online. This is an ideal text for graduate courses on multilevel, longitudinal, latent variable modelling, multivariate statistics, or advanced quantitative techniques taught in psychology, business, education, health, and sociology. Recommended prerequisites are introductory univariate and multivariate statistics.

Multilevel Modeling Methods with Introductory and Advanced Applications provides a cogent and comprehensive introduction to the area of multilevel modeling for methodological and applied researchers as well as advanced graduate students. The book is designed to be able to serve as a textbook for a one or two semester course in multilevel modeling. The topics of the seventeen chapters range from basic to advanced, yet each chapter is designed to be able to stand alone as an instructional unit on its respective topic, with an emphasis on application and interpretation. In addition to covering foundational topics on the use of multilevel models for organizational and longitudinal research, the book includes chapters on more advanced extensions and applications, such as cross-classified random effects models, non-linear growth models, mixed effects location scale models, logistic, ordinal, and Poisson models, and multilevel mediation. In addition, the volume includes chapters addressing some of the most important design and analytic issues including missing data, power analyses, causal inference, model fit, and measurement issues. Finally, the volume includes chapters addressing special topics such as using large-scale complex sample datasets, and reporting the results of multilevel designs. Each chapter contains a section called Try This!, which poses a structured data problem for the reader. We have linked our book to a website (http://modeling.uconn.edu) containing data for the Try This! section, creating an opportunity for readers to learn by doing. The inclusion of the Try This! problems, data, and sample code eases the burden for instructors, who must continually search for class examples and homework problems. In addition, each chapter provides recommendations for additional methodological and applied readings.

Multilevel modeling is an increasingly popular multivariate technique that is widely applied in the social sciences. Increasingly, practitioners are making instructional decisions based on results from their multivariate analyses, which often come from nested data that lend themselves to multilevel modeling techniques. As data-driven decision making becomes more critical to colleges and universities, multilevel modeling is a tool that will lead to more efficient estimates and enhance understanding of complex relationships. This volume illustrates both the theoretical underpinnings and practical applications of multilevel modeling in IR. It introduces the fundamental concepts of multilevel modeling techniques in a conceptual and technical manner. Providing a range of examples of nested models that are based on linear and categorical outcomes, it then offers important suggestions about presenting results of multilevel models through charts and graphs. This is the 154th volume of this Jossey-Bass quarterly report series. Always timely and comprehensive, New Directions for Institutional Research provides planners and administrators in all types of academic institutions with guidelines in such areas as resource coordination, information analysis, program evaluation, and institutional management.

This book provides a broad overview of basic multilevel modeling issues and illustrates techniques building analyses around several organizational data sets. Although the focus is primarily on educational and organizational settings, the examples will help the reader discover other applications for these techniques. Two basic classes of multilevel models are developed: multilevel regression models and multilevel models for covariance structures--are used to develop the rationale behind these models and provide an introduction to the design and analysis of research studies using two multilevel analytic techniques--hierarchical linear modeling and structural equation modeling.

Selecting Research Methods provides advice from prominent social scientists concerning the most crucial steps for planning and undertaking meaningful research: selecting the methods to be used. Contributors to the collection address methodological choices in four stages: design, sampling, coding and measurement, and analysis. The volumes provide an integrated approach to methodological choice in two ways. First, the contributions range from the early decisions about design options through the concluding choices about analyzing, interpreting, and presenting results. Second, the collection is integrated because it addresses the needs of projects that collect qualitative evidence, quantitative data, or both. Volume 1 concerns design choice; the articles focus on selecting designs that are effective for answering research questions and achieving the goals of the researcher. Volume 2 is on sampling and includes, in addition to sampling from populations, advice on choosing methods for recruiting informants for interviews, selecting sites for participant observation, and assigning subjects to control and experimental groups. Volume 3 reviews options for coding and measurement; it emphasizes methodological choices that enable researchers to study concepts in ways that enhance the reliability and validity of the research. Finally, the articles included in Volume 4 review the range of choices available among methods to analyze results and interpret the meanings of evidence

In the short time since the publication of the Handbook of Positive Psychology esearch results on the psychology of human strengths have proliferated. However, no major volume has documented the methods and theory used to achieve these results. Oxford Handbook of Methods in Positive Psychology fills this need, providing a broad overview of diverse contemporary methods in positive psychology. With contributions from both leading scholars and promising young investigators, the handbook serves to illuminate and, at times, challenge traditional approaches. Incorporating multiple levels of analysis, from biology to culture, the contributors present state-of-the art techniques, including those for estimating variability and change at the level of the individual, identifying reliability of measurements within and across individuals, and separating individual differences in growth from aspects of phenomena that exhibit shorter-term variability over time. The volume covers such topics as wisdom, health, hope, resilience, religion, relationships, emotions, well-being, character strengths, and laughter. It enhances our understanding of the balance between human deficits and strengths and demonstrates their connections to other problems. Oxford Handbook of Methods in Positive Psychology will be the essential reference for methods in positive psychology.
