An organizational psychologist was investigating whether work tension and collegiality were predictors of job satisfaction. However, research indicated that work tension and collegiality interact, so a SEM Interaction Model was hypothesized and tested. The Interaction Model is diagrammed in Figure 16.6. Use LISREL to OPEN the PRELIS system file, jobs. psf, then proceed to follow the necessary steps to create the latent variables (work tension, collegiality, and job satisfaction, interaction) and add them to the PRELIS system file. Next, create and run a LISREL-SIMPLIS program to test the interaction model. What conclusions can you make regarding the interaction of the latent variables work tension and collegiality?

Key Concepts

LISREL and PRELIS

LISREL is a widely used software package for SEM that provides tools for model specification, estimation, and testing. The PRELIS system file is used within the LISREL environment to prepare data, create latent variables, and incorporate these into the SEM analysis. Utilizing these tools, researchers can construct and test sophisticated models, including those involving interactions among latent variables, ensuring that the data are appropriately structured for the analysis.

Latent Variable Interaction

Latent variable interaction refers to the statistical analysis of how two or more latent constructs interact to influence an outcome variable. Modeling such interactions is complex because the indicators for the latent variables are not directly observed; instead, product indicators or specialized estimation techniques are often used to capture the interaction effect. This approach allows researchers to examine whether the relationship between one latent variable and an outcome varies according to the level of another latent variable.

Latent Variables

Latent variables are unobserved constructs that are inferred from multiple observed indicators. These variables represent theoretical concepts such as job satisfaction or work tension, which cannot be measured directly but are estimated through related observable measures. The use of latent variables helps control for measurement error and offers a more reliable assessment of the underlying constructs in a model.

Structural Equation Modeling (SEM)

Structural Equation Modeling is a comprehensive statistical approach that is used to analyze complex relationships among observed and latent variables. It involves specifying a theoretical model, estimating parameters, and testing hypothesized relationships, including direct, indirect, and interaction effects. SEM provides researchers with the tools to assess model fit and understand how latent constructs interplay in predicting outcomes.
