Report on Time, Process and QCA

In Fall of 2022, Lasse Gerrits and Sofia Pagliarin, both of the Institute for Housing and Urban Development Studies, Erasmus University Rotterdam, organized the first Time-in-QCA (TiQ) workshop. They have now produced a corresponding report of the workshop. More than just reviewing the workshop itself, this report is essential reading for anybody interested in longitudinal QCA: it summarizes existing conceptualizations of the relationships among time and QCA, provides a high-level overview of methodological techniques for incorporating time and process into QCA, and identifies avenues and areas for future exploration.

Necessary Condition Analysis (NCA) Summer Course

Stefan Breet and Professor Jan Dul (the founder of Necessary Condition Analysis) are excited to announce a week-long summer course on Necessary Condition Analysis. The one-week summer course will take place from June 26, 2023 till June 30, 2023 at the Radboud University in Nijmegen, The Netherlands. It is part of the 2nd Summer School in Social Research Methods organized by MethodsNet. For information or to sign up for the course visit Radboud Summer School website and fill out the application form.

Necessary Condition Analysis (NCA) MOOC on Coursera

An online course about Necessary Condition Analysis (NCA) is now available on the Coursera website for Massive Open Online Courses (MOOCs). The course is freely available for anyone who wants to learn about NCA. This beginners’ course includes 29 videos and is organized in 5 weeks:

  1. Introduction to NCA
  2. Setting up an NCA study
  3. Data analysis with NCA
  4. Reporting the results of NCA
  5. Advanced topics of NCA.

NCA can be used as a stand-alone method, in combination with regression-based methods, or in combination with QCA. The course can be accessed via the following link:

New Working Paper by Lauri and Saar

“Intergenerational Transmission of Education: Set-Theoretic Exploration of Accumulation of Social Advantages and Disadvantages in Six European Countries” by Triin Lauri (Tallinn University) and Ellu Saar (Tallinn University).

The aim of the paper is to investigate the patterns of multiple advantages and disadvantages of parental resources measured by educational attainment of both parents as well as parental cultural resources and their impact on the educational attainment of offspring across three cohorts in six European countries – the Czech Republic, Estonia, Germany, Italy, Sweden, and the United Kingdom. We separate the examination of combined advantages from that of combined disadvantages to emphasise the asymmetries in these relationships by employing a novel configurational approach, set coincidence analysis introduced by Ragin and Fiss (2017). The analysis based on the International Assessment of Adult Competencies data (PIAAC) revealed substantial country differences in degrees of cumulative advantages and disadvantages of respondents’ parental resources and also in the linkages between these cumulative patterns and respondents’ educational attainment.

New YouTube Page

COMPASSS now has a YouTube page. Thanks to Sophia Pagliarin for spearheading this initiative! There are just two videos available now but we’d like to highlight talks by members of the COMPASSS community on QCA and related configurational-comparative methods. If you have a talk that you’d like us to host, please contact Claude.

Announcing the QCA Conference of the Americas (AQCA)

We are pleased to announce the launch of the annual QCA Conference of the Americas. Organized by Claude Rubinson (U Houston-Downtown), Peer Fiss (U Southern California) and Gary Goertz (Notre Dame), the inaugural meeting will be held April 6-8, 2022 at the University of Houston-Downtown. Charles Ragin (UC Irvine) and James Mahoney (Northwestern) will deliver the keynote addresses.

Responding to the growing interest in understanding causally complex phenomena in a configurational and comparative manner, AQCA will provide a venue for the broad, cross-disciplinary community of QCA empirical researchers and methodologists to gather together to present and receive feedback on current research projects, share theoretical and methodological developments, and discuss new directions in configurational-comparative research practices. AQCA offers a supportive environment for the diverse QCA community to meet, engage in dialogue, network, learn, and collectively move forward on advancing the configurational-comparative perspective.

AQCA will be a broad-tent, inclusive, and diverse venue that is open to everyone interested in learning about, using, and advancing the configurational-comparative perspective. Whatever your field or topic, if you use QCA and/or other configurational-comparative methods or if you are considering using them, then AQCA is for you. Whether your work is empirical, methodological, or theoretical; whether you are a seasoned practitioner or have just discovered the configurational-comparative approach, we hope that you will join us for three days of lively discussions, debates, community building, and learning.

We hope that you will join us in April. For more details and to review our call for abstracts (due date: January 31, 2022), please visit the AQCA website at

New Book: Qualitative Comparative Analysis: An Introduction to Research Design and Application

Patrick A. Mello (Technical University of Munich) has published Qualitative Comparative Analysis: An Introduction to Research Design and Application (Georgetown University Press, 2021).

Qualitative Comparative Analysis: An Introduction to Research Design and Application is a comprehensive guide to QCA. As QCA becomes increasingly popular across the social sciences, this textbook teaches students, scholars, and self-learners the fundamentals of the method, research design, interpretation of results, and how to communicate findings.

Following an ideal typical research cycle, the book’s ten chapters cover the methodological basis and analytical routine of QCA, as well as matters of research design, causation and causal complexity, QCA variants, and the method’s reception in the social sciences. A comprehensive glossary helps to clarify the meaning of frequently used terms. The book is complemented by an accessible online R manual to help new users to practice QCA’s analytical steps on sample data and then implement with their own findings. This hands-on textbook is an essential resource for students and researchers looking for a complete and up-to-date introduction to QCA.

New Book: Qualitative Comparative Analysis with R: A Beginner’s Guide

Ioana-Elena Oana (European University Institute), Carsten Q. Schneider (Central European University), and Eva Thomann (Universität Konstanz) have released Qualitative Comparative Analysis with R: A Beginner’s Guide (Cambridge University Press 2021).

A comprehensive introduction and teaching resource for state-of-the-art Qualitative Comparative Analysis (QCA) using R software. This guide facilitates the efficient teaching, independent learning, and use of QCA with the best available software, reducing the time and effort required when encountering not just the logic of a new method, but also new software. With its applied and practical focus, the book offers a genuinely simple and intuitive resource for implementing the most complete protocol of QCA. To make the lives of students, teachers, researchers, and practitioners as easy as possible, the book includes learning goals, core points, empirical examples, and tips for good practices. The freely available online material provides a rich body of additional resources to aid users in their learning process. Beyond performing core analyses with the R package QCA, the book also facilitates a close integration with the R package SetMethods allowing for a host of additional protocols for building a more solid and well-rounded QCA.
