Comparing the Analysis Results of the Structural Equation Models (SEM) Conducted Using LISREL and AMOS

This study aimed to compare the analysis results obtained through LISREL and AMOS for the models of path analysis, Confirmatory Factor Analysis (CFA) and structural regression, which are within structural equation model and differ in levels of fit. Therefore, population and sample were not needed in the study. The study was conducted on three different data sets that reflected the models through a data file. The data set used in the path analysis was determined to reflect a low fit model, while the one used in CFA was determined to reflect an acceptable fit model. However, the data set used in the structural model reflected a good fit. In this way, it was believed that it would be possible to find an answer to the question of whether the differences in the fit indexes obtained through LISREL and AMOS were affected by the fit level of the model analyzed. The analysis results indicated that the fit indexes obtained through LISREL and AMOS were substantially similar in the data set that reflected a good fit. The differences in the fit indexes obtained through these two software packages were found to be larger in the model that reflected a low fit between the model and the data set. It was also found that this difference was remarkable, particularly in chi(2)/sd, NNFI and RFI indexes. These results indicate that the differences in the fit indexes reported by LISREL and AMOS are affected by the fit level of the model.
