Many people have been addicted to internet and game. The addiction has aroused great concern from the public and specialists. In this paper we measure the psychological state of internet addicts by some famous mental scales, and investigate their life qualities by some questionnaires. When we get basic data we make some basic statistical analysis, and use structural equations model (SEM) to analyze...
Structural equation model (SEM) has been widely applied in many fields in recent years. This paper builds a SEM to analyze social-psychological health of Internet users. We give the index system for the SEM and describe the relationships among the latent variables. Meanwhile we give a definite linear algorithm for SEM. Our algorithm is different from the traditional algorithms such as PLS and LISREL,...
In recent years, SEM is widely used in many fields. This paper builds a mental health evaluation model for earthquake-stricken masses through the principle of structural equation model. Based on our MCLS solution for measurement equation by adding a constraint with modular length to the latent variable, we change the modular lengths of latent variables so that the path coefficients between any latent...
