Structural equation modeling software is typically used for performing confirmatory factor analysis. CFA is also frequently used as a first step to assess the proposed measurement model in a structural equation model. Many of the rules of interpretation regarding assessment of model fit and model modification in structural equation modeling apply equally to CFA.
CFA is distinguished from structural equation modeling by the fact that in CFA, there are no directed arrows between latent factors. In other words, while in CFA factors are not presumed to directly cause one another, SEM often does specify particular factors and variables to be causal in nature.
In the context of SEM, the CFA is often called 'the measurement model', while the relations between the latent variables with directed arrows are called 'the structural model'. In CFA, several statistical tests are used to determine how well the model fits to the data. Absolute fit indices determine how well the a priori model fits, or reproduces the data. The chi-squared test indicates the difference between observed and expected covariance matrices. Values closer to zero indicate a better fit; smaller difference between expected and observed covariance matrices.
One difficulty with the chi-squared test of model fit, however, is that researchers may fail to reject an inappropriate model in small sample sizes and reject an appropriate model in large sample sizes. The root mean square error of approximation RMSEA avoids issues of sample size by analyzing the discrepancy between the hypothesized model, with optimally chosen parameter estimates, and the population covariance matrix.
The root mean square residual RMR and standardized root mean square residual SRMR are the square root of the discrepancy between the sample covariance matrix and the model covariance matrix. The goodness of fit index GFI is a measure of fit between the hypothesized model and the observed covariance matrix. The normed fit index NFI analyzes the discrepancy between the chi-squared value of the hypothesized model and the chi-squared value of the null model.
The comparative fit index CFI analyzes the model fit by examining the discrepancy between the data and the hypothesized model, while adjusting for the issues of sample size inherent in the chi-squared test of model fit,  and the normed fit index. Previously, a CFI value of. Thus, a CFI value of. To estimate the parameters of a model, the model must be properly identified. This equation is known as the "t rule".
If there is too little information available on which to base the parameter estimates, then the model is said to be underidentified, and model parameters cannot be estimated appropriately.

Exploratory and confirmatory factor analysis: Understanding concepts and applications. First, we have to define the individual constructs. The first step involves the procedure that defines constructs theoretically. This involves a pretest to evaluate the construct items, and a confirmatory test of the measurement model that is conducted using confirmatory factor analysis CFA , etc.
Developing the overall measurement model theory: In confirmatory factor analysis CFA , we should consider the concept of unidimensionality between construct error variance and within construct error variance.
At least four constructs and three items per constructs should be present in the research. Designing a study to produce the empirical results: The measurement model must be specified. Most commonly, the value of one loading estimate should be one per construct.
Two methods are available for identification; the first is rank condition, and the second is order condition. Assessing the measurement model validity: Assessing the measurement model validity occurs when the theoretical measurement model is compared with the reality model to see how well the data fits.
To check the measurement model validity, the number of the indicator helps us.
