Hu & Bentler (1999) proposed the goodness of model fit are: CFI (Comparative Fit Index) and GFI should be close to 0.95, SRMR close to 0.06 or 0.08, and RMSEA close to 0.06. As shown in Table 5, the model test results show that the degree of freedom of the model is equal to 59, the chi-square value of the overall model fit is 140.116, the ratio of chi-square degrees of freedom is 2.375, and the significance probability value is p<0.000, RMSEA=0.071< 0.080, SRMR=0.053<0.06, CFI=0.968>0.950, TLI=0.958>0.950, all indicators are within the acceptable range and reach the model adaptation standard, so the model can be accepted.

It can be seen from Table 5 and Table 6, that part from the hypothesis of the research model has been verified (p<0.001). Among them, the residual of the model has no negative value, and the correlation between the independent variables is less than 0.7, which means that there is no co-linearity. Therefore, according to the research hypothesis, except for the independent variable of general health, there is a significant influence relationship between web-based learning tools, self-efficacy and the quality of family life. Depression-anxiety-stress has no significant positive impact on web-based learning tool.
