Confirmatory factor analysis and an application on beck's depression inventory

Confirmatory factor analysis is a basic method for structural equation modelling and based on researcher?s a priori hypothesis. As mentioned the results of confirmatory depends on researcher theorical leading and its consideration on variables. At that process the models which are applicated with explonatory factor analysis are great sources for researcher. The first rule in confirmatory factor analysis is that the model and contained parameter have to be identified otherwise the estimation results would be inappropriate. There have to be some constraint to get model identified. In refer to results of analysis the model could have an acceptable fit or need to be modified. There are such criters to evaluate the models fit.(e.g. ki-square, goodness of fit, Tucker&Lewis etc.) Key Words: Confirmatory factor analysis, structural equation modelling, lisrel(inear structural relationship), Beck Depression Inventory
