A conceptual overview of Structural Equation Modeling (SEM) in rehabilitation research.

Structural Equation Modeling (SEM) is a collection of statistical techniques used to determine the degree to which a proposed theoretical model is supported by data. SEM has been growing in various disciplines as well as in rehabilitation research. It is the goal of this introduction to provide a conceptual overview of SEM. This statistical technique can facilitate a better understanding of large data sets involving theoretical models that have become more frequent in this discipline.
