Peter Schmidt is Professor Emeritus at the Department of Political Science and the Centre of International Development and Environment (ZEU) at the University of Giessen. His research interests are the foundations and applications of structural equation models, methods for cross-cultural analysis, analysis of panel data, and empirically testing wide versions of rational choice theory like the reasoned action approach. Applications include studies of national identity, inter-ethnic relations, attitudes toward immigration, values and environmental behaviour. He has published several books and recently published in the Annual Review of Sociology, European Sociological Review, Journal for Ethnic and Migration Research, International Journal of Comparative Sociology, Journal for Cross-Cultural Psychology, Frontiers in Psychology, European Journal of Social Psychology, Psychological Methods, Structural Equation Modeling, Public Opinion Quarterly, Survey Research Methods and Sociological Methods and Research.

Dr. Daniel Seddig is a Sociologist at the University of Cologne (Germany). His research interests are comparative and panel data analysis using structural equation modelling. Substantive topics are human values, crime, immigration, age and health. He has taught Structural Equation Modelling at university level and the GESIS summer school.

**Course Content**The course shows how theoretical assumptions concerning measurement models and substantive models can be translated into a structural equation model, and how the model can be estimated and tested with the Mplus 8 computer program. In the first part, we deal with confirmatory factor analysis (CFA), which relate multiple indicators to one (CFA) or several latent variables (Simultaneous Confirmatory Factor Analysis, Bifactor Models and second order confirmatory factor analysis). Different specifications of measurement models are tested via confirmatory factor analysis (CFA) as a special case of a structural equation model (SEM) and we will discuss scale building procedures and adequate reliability and validity estimates.

Special emphasis is given to the (cross cultural) analysis of multiple groups (MGCFA) for comparisons between groups and over time points (repeated cross-sections), including the assessment of measurement invariance (i.e., comparability of intercepts of observed variables and factor loadings) to compare latent means. We also deal with the new procedures of measurement invariance testing (e.g., alignment optimization) as alternatives to check weak and strict measurement invariance.

The second part comprises both the structural model and the measurement model. Topics include recursive vs. non-recursive models for the structural part of the model, moderation (interaction effects) and mediation analyses, treatment missing data and the use of formative vs. reflective indicators in MIMIC Models. Again, special emphasis will be directed toward the use of the multiple-group option for cross-group comparisons of both the measurement and the structural model. A major focus will be the process of model modification and alternative model testing using adequate fit measures and how to report CFA and SEM results.

We will draw all examples are from data of the European Social Survey (ESS) and use the concept of values as operationalized by the Portrait Value Questionnaire developed by Schwartz for single country or cross-cultural analyses. Nonetheless, participants from all fields are welcome to participate.

**Course Objectives**The objectives of this course are

1. to enable participants to use (multiple group) confirmatory factor analysis and (multiple group) structural equation modelling to develop and/or test both measurement models and scales and, furthermore, causal theories with latent variables.

2. to familiarize participants with the Mplus 8 program to handle the most important standard models. Nonetheless, to facilitate the transfer of the course content to other programs, all example syntaxes will also be supplied for STATA_SEM and R lavaan..

3. to increase participants’ competencies in the applications of the techniques and models with their own data. Therefore, participants are highly encouraged to bring their own data as cleaned raw data files (see for input specifications of the data, e.g., Byrne 2012) and to use them for developing their models and projects for a dissertation or publications during the course. We will offer consultation hours from the beginning both by the instructor and the teaching assistant to answer individual questions and specially to support participants to perform analyses with their own data. Moreover, we will offer an open colloquium format to present and critically discuss the own research findings.

**Course Prerequisites**Participants are expected to have extensive familiarity with Windows applications, good knowledge of exploratory factor analysis and regression analysis is required. The course is most optimal for those who want to apply CFA and SEM within the next twelve months.
