This course provides an overview of the fundamentals of SEM. As well as the statistical theory, an overview of the many applications and capabilities of SEM is given.
This course is designed as an introductory course for applied researchers and as such, is suitable for participants who want to develop a fundamental knowledge of SEM techniques. Some participants may want to follow this course by the applied and advanced SEM workshops taught by ACSPRI.
Dr Mark Griffin is the Founding Director of the Australian Development Agency for Statistics and Information Systems (www.adasis-oz.com), and holds an Adjunct appointment within the School of Public Health, University of Queensland. Mark serves on the Executive Committee for the Statistical Society of Australia, and is the Asia-Pacific Deputy Regional Director for the International Institute of Business Analysis. He has been the primary statistician and survey methodologist for a 6000-household survey exploring human trafficking in Cambodia, China, Laos, Myanmar, Thailand and Vietnam, and for a survey of 20,000 households exploring human trafficking in Sri Lanka. He is currently leading program evaluation teams for the Queensland Department of Communities, Child Safety, and Disability Services. To date he has presented over 80 two-day workshops in statistics around Australia.
Structural equation modelling—or structural equations with latent variables—is a very general statistical model and widely used method. For example, SEM is used in fundamental disciplines such as the social, economic and psychological sciences, the biological sciences, and applied disciplines such as education, health and marketing.
SEM has become popular for several reasons, apart from its generality:
(i) all SEM models can be represented visually,
(ii) a standard notation helps researchers to communicate, and
(iii) several software packages for estimating SEM models are readily available (e.g., AMOS, LISREL, Mplus, R).
This course provides an overview of the fundamentals of SEM. As well as the statistical theory, an overview of the many applications and capabilities of SEM is given. The course is not particularly mathematical, but instead places emphasis on the fundamental concepts of SEM and how it is used by applied researchers.
General aims of the course are for students to develop a readiness for using SEM software and to develop the requisite knowledge for applying SEM methods and models in an intelligent way. Note that participants may be invited to briefly present their own research on the last day of class. This exercise, along with the formal lecture material, might help participants to chart a direction forward in their study and application of SEM.
- Revision of linear regression, correlation and covariance and how to interpret SPSS output
- Building regression and path models using an SEM framework
- General stages of SEM modelling – specification, identification, estimation, testing, and modification
- Reporting SEM research
- Exploratory factor analysis
- Confirmatory factor analysis and latent variables
- Tests for mediation and moderation
- Related groups models and higher order latent factors
- Multilevel models
- Latent Growth models
- SEM diagnostics including assessing normality, outliers, linearity, and the presence of missing data
- Time for presenting your own models – for those workshop participants who would like to present, there will be an opportunity for you to draw an SEM model from your research on the board to discuss with the class and get feedback. These models might come from current or future proposed research. This discussion will focus on the arrangement of variables that compose an SEM, rather than on the statistical output produced in fitting such models.
- There will also be time, particularly at the end of the workshop, for participants to ask questions about fitting SEM models to their own data.
This course will take place in a computer lab unless otherwise notified.
Approximately half of the time during this course will be spent in PowerPoint presentations, and half of the time in computer demonstrations and self-paced computer exercises. The majority of the computer exercises will be conducted in AMOS, the remaining secondary exercises will be conducted in SPSS.
Participants must have completed the course Fundamentals of Multiple Regression or an equivalent course at university level and/or have equivalent experience. Familiarity with analysis of variance, factor analysis or regression is desirable, but not strictly necessary. It is assumed that participants have little or no familiarity of structural equations with latent variables.

Q: Do I have to have any prerequisites to do this course?
A: Yes, you must have completed Fundamentals of Multiple Regression or a University course at the same level
Q: What should I bring to the workshop?
A: Different workshop participants will be at different stages of their research. While we will explore prepared computer exercises with provided datasets during this workshop, some participants might want to bring their own data to this workshop to analyse as well. In addition workshop participants will also have the opportunity to present their own SEM models to the class (where this might involve current or future research). There is no requirement for participants to have their own data or to present their SEM models, but some participants may want to take advantage of this opportunity.
Lots of 1 on 1 time with the instructor was very helpful. (Winter 2016)
Mark is very helpful. He always answer all the questions. Spend time helping students to do exercising.
Thank you so much Mark. You are a great teacher. (Winter 2016)
Great to learn the theory and then consolidate it with practical activities. (Winter 2015)
The structure of smaller lectures was great. This content then scaffolded computer activities. (Winter 2015)
Great introduction to SEM and to a couple of the software packages to use, now understand how SEM can be used and how to go about the process. (Summer 2015)
The fundamentals and ground work covered was exeptionally useful. I feel I now have a very solid understanding of regression, path analysis and SEM. (Summer 2015)
The instructor's bound, book length course notes will serve as the course texts.
