This proceedings book highlights the latest research and developments in psychometrics and statistics. Featuring contributions presented at the 82nd Annual Meeting of the Psychometric Society (IMPS), organized by the University of Zurich and held in Zurich, Switzerland from July 17 to 21, 2017, its 34 chapters address a diverse range of psychometric topics including item response theory, factor analysis, causal inference, Bayesian statistics, test equating, cognitive diagnostic models and multistage adaptive testing. The IMPS is one of the largest international meetings on quantitative measurement in psychology, education and the social sciences, attracting over 500 participants and 250 paper presentations from around the world every year. This book gathers the contributions of selected presenters, which were subsequently expanded and peer-reviewed.

Examining selected statistical and modeling approaches in psychology, the book concentrates on the topics of mental test theory and theory of measurement. The main objective is not only to present a critical view of the approaches suggested up until now, but also their reinterpretation, extension and enrichment by new theories and concepts, for example, formal theories of semiotics and knowledge, and a unifying theory of actions.The book also shows a relation between test theory and the foundations of fuzzy set theory. It presents new models of measurement tools and new measurement theories of concepts such as objective and subjective time, risk or utility, and discusses the cognitive foundations of these theories, namely the theory of perception and observability.

The research articles in this volume cover timely quantitative psychology topics, including new methods in item response theory, computerized adaptive testing, cognitive diagnostic modeling, and psychological scaling. Topics within general quantitative methodology include structural equation modeling, factor analysis, causal modeling, mediation, missing data methods, and longitudinal data analysis. These methods will appeal, in particular, to researchers in the social sciences. The 80th annual meeting took place in Beijing, China, between the 12th and 16th of July, 2015. Previous volumes to showcase work from the Psychometric Society’s Meeting are New Developments in Quantitative Psychology: Presentations from the 77th Annual Psychometric Society Meeting (Springer, 2013), Quantitative Psychology Research: The 78th Annual Meeting of the Psychometric Society (Springer, 2015), and Quantitative Psychology Research: The 79th Annual Meeting of the Psychometric Society, Wisconsin, USA, 2014 (Springer, 2015).

Quantitative Psychological Research: The Complete Student's Companion, expertly guides the reader through all the stages involved in undertaking quantitative psychological research: designing a study, choosing a sample of people, undertaking the study, analysing the data, and reporting the research. Accessibly written and clearly presented, the book is designed for anyone learning to conduct quantitative psychological research as well being a reference work for professional psychologists. It covers the full research process, from the original idea to reporting the completed study, emphasizing the importance of looking beyond statistical significance in evaluating data. The book provides step-by-step guidance on choosing, interpreting and reporting the appropriate analysis, featuring worked examples and extended calculations as appendices for readers who wish to delve further. This edition features a new chapter examining ideas on how causality might be identified when data is not obtained from an experiment and has been thoroughly updated throughout to reflect latest research practices. Care has been taken to avoid tying the book to any specific statistical software, providing readers with a thorough grounding in the basics no matter which package they go on to use. This is a must read for professional psychologists as well as students and researchers of Psychology, Statistics and Research Methods. This book is also invaluable for anyone interested in conducting quantitative psychological research.

This book expertly guides the reader through all stages involved in undertaking quantitative psychological research, from accessing the relevant literature, through designing and conducting a study, analysing and interpreting data, and finally reporting the research. This third edition includes two new chapters - on preliminary checking of data and allowing for additional variables when comparing the means of different conditions - and expands on original topics such as choosing sample sizes and how to test for mediation effects. It also contains increased coverage of tests and further detail of techniques and terms which psychologists will meet when working with those in the medical professions. As the chapters focus on choosing appropriate statistical tests and how to interpret and report them (rather than the detailed calculations, which appear in appendices), the reader is able to gain an understanding of a test without being interrupted by the need to understand the complex mathematics behind it. In addition, for the first time, the book is accompanied by an online bank of multiple choice questions. The book helps readers to: Locate reports of relevant existing research Design research while adhering to ethical principles Identify various methods which can be used to ask questions or observe behaviour Choose appropriate samples Display and analyse findings numerically and graphically to test hypotheses Report psychological research in a variety of ways. As such, the book is suitable for psychology students and professionals at all levels, and is particularly useful to those working in Health and Clinical Psychology.

Understanding Quantitative and Qualitative Research in Psychology is the most hands-on, accessible and approachable guide to the entire research process, which fully explores both quantitative and qualitative methods to give students the knowledge and confidence they need. Students arepresented with a practically-focused guide to carrying out psychological research and are taken from formulating a research question through to collecting data, analysing datasets statistically with SPSS or qualitatively with a range of approaches, and finally presenting and thinking criticallyabout research findings. They are shown the importance of research ethics, and coverage of the replication crisis and the open science movement is considered throughout.The online resources present a wealth of opportunities for students to practice what they have learned, and the title is supported by an excellent range of video support materials for both the qualitative and quantitative sections, including SPSS screencasts for all relevant chapters, and a range ofvideos on interview skills.Digital formats and resourcesUnderstanding Quantitative and Qualitative Research in Psychology is available for students and institutions to purchase in a variety of formats, and is supported by online resources.The e-book offers a mobile experience and convenient access, along with self-assessment activities and multi-media content to provide additional learning support: www.oxfordtextbooks.co.uk/ebooks/.The online resources include:For students:- Videos demonstrating interview technique- SPSS screencasts showing students how to carry out the statistical analyses covered in the book- Flashcards- SPSS datasets- Audio files of sample interviews- Transcriptions of sample interviews- Initial codes for a sample thematic analysis- Memo template and transcription template to accompany the grounded theory chapter- SPSS output files- Answers to study questions- Web references- An example qualitative studyFor lecturers:- Customizable PowerPoint presentations- Image bank- Test bank- Additional worksheets- Answer sheets- Additional datasets- Additional SPSS output files

"This new book by Carla Willig closes a gap in qualitative research in psychology and beyond. It focuses on the process of understanding in qualitative data analysis by taking the perspective of interpretation: What links our understanding with social and psychological phenomena in qualitative research? With its broad coverage of the literature and its clear style of writing it will be most helpful for anyone applying qualitative research to psychological phenomena." Uwe Flick, Alice Salomon University, Berlin and Vienna Universities "In this work Carla Willig takes on one of the most pressing challenges in qualitative inquiry: how are we to confront multiplicity in interpretation? I began reading with great curiosity; I came away feeling that this is the best treatment of this complex subject I have yet encountered. Combining conceptual sophistication, the skill of clarity, and a welcome sense of balance, Willig illuminates and enriches. Her discussion on the ethics of interpretation sets the book apart. Now I clamor to join the discussions demanded by this fascinating work." Kenneth Gergen, Senior Research Professor, Swarthmore College, USA "Carla Willig's balanced and insightful text goes to the heart of what is stake in debates over qualitative analysis: the act of interpretation itself. Beginning with the idea that the researcher must recognise both the responsibility and privilege of research, Willig clearly demonstrates how interpretation is actually performed and how to negotiate the epistemological and practical issues that are involved. Opposing the tendency for the researcher to disappear in the act of 'doing analysis', this book offers a distinctively human and affective vision of interpretative work. There is much here for both dedicated qualitative researchers and curious empiricists of every stripe. Students of psychology, read on: you have nothing to lose but your prejudices." Steven Brown, Professor of Social and Organisational Psychology, University of Leicester, UK "At last! This is the book that qualitative researchers in psychology have required for some time, and it fills a significant gap for the field. Willig provides a brilliantly written comprehensive account of the importance and value of interpretation in qualitative research, covering theory, ethics and debate around interpretation, and including detailed practical applications that reveal the complexities and complications involved in interpretative analytic work. This text exposes the necessity of reaching for interpretation in qualitative data analysis, and is essential reading for qualitative researchers, whatever their level of expertise, both within and beyond psychology." Kerry Chamberlain, Professor of Social and Health Psychology, Massey University, New Zealand Interpretation is an integral part of all qualitative research, yet relatively little has been written about its process. In her new book, Carla Willig, author of international bestseller Introducing Qualitative Research Methods in Psychology, sheds light on the role of interpretation in qualitative research in psychology and describes the different approaches for practice. Packed with case studies, two full interview transcripts and worked examples from psychology, health sciences and the arts, Willig skilfully guides you to conduct qualitative research which is interpretative and based upon a clear rationale and interpretative position. You will also learn how to evaluate interpretative research and to acquire an understanding of what constitutes best ethical practice. Carla's transcribed conversations with Stephen Frosh, Christine Griffin and Jonathan Smith about the meaning and practice of interpretation provide a fascinating insight into the ways in which highly experienced researchers engage with the challenge of interpreting qualitative data. This book will be valuable reading for all psychology students, researchers and practitioners and a useful reference for students across the social sciences and related health disciplines.

One of our bestselling handbooks, The SAGE Handbook of Qualitative Research in Psychology, is back for a second edition. Since the first edition qualitative research in psychology has been transformed. Responding to this, existing chapters have been updated, and three new chapters introduced on Thematic Analysis, Interpretation and Netnography. With a focus on methodological progress throughout, the chapters are organised into three sections: Section One: Methods Section Two: Perspectives and Techniques Section Three: Applications In the field of psychology and beyond, this handbook will constitute a valuable resource for both experienced qualitative researchers and novices for many years to come.

This work, which provides a guide for revising and expanding statistical and quantitative methods pedagogy, is useful for novice and seasoned instructors at both undergraduate and graduate levels, inspiring them to use transformative approaches to train students as future researchers. Is it time for a radical revision in our pedagogical orientation? How are we currently teaching introductory statistics and quantitative methods, and how should we teach them? What innovations are used, what is in development? This ground-breaking edited volume addresses these questions and more, providing cutting-edge guidance from highly accomplished teachers. Many current textbooks and syllabi differ in only superficial ways from those used 50 years ago, yet the field of quantitative methods—and its relationship to the research enterprise—has expanded in many important ways. A philosophical axiom underlying this book is that introductory teaching should prepare students to potentially enter more advanced quantitative methods training and ultimately to become accomplished researchers. The reader is introduced to classroom innovation, and to both pragmatic and philosophical challenges to the status quo, motivating a broad revolution in how introductory statistics and quantitative methods are taught. Designed to update and renovate statistical pedagogy, this material will stimulate students, new instructors, and experienced teachers.
