Abstract: One nomological network consists of the original model, antecedents, or consequences. Through the application of Structural Equation Model, researchers can test the nomological validity of various components and modify the original model. According to nomological network, the causation among multi-variables can also be scientifically revealed. And the problems which need to be pay attention to were discussed. Based on theoretical study and empirical study, researchers may (1) structure the basic theoretical framework of nomological network, (2) develop and validate measuring tools effectively by applying this method, (3) explore the influential factors of the validity.

Key words: nomological network, nomological validity, construct validity
