Structural equation model
As shown in Fig 1, there is a significant positive correlation between self-efficacy and family quality of life with a correlation coefficient of 0.533 (p<0.001). There is a significant negative correlation between self-efficacy and depression-anxiety-stress, the correlation coefficient is -0.196 (p<0.01). There is a significant negative correlation between family quality of life and depression-anxiety-stress, the correlation coefficient is -0.297 (p<0.001).
Self-efficacy scale have a direct positive impact on web-based learning tools, with a path coefficient of 0.234 (p<0.01). Family quality of life have a direct positive impact on web-based learning tools, with a path coefficient of 0.272 (p<0.001). Furthermore, depression-anxiety-stress has no significant impact on web-based learning tools. Among all the dependent variables, family quality of life have the greatest impact on the web-based learning tools, while the one that has the greatest impact on self-efficacy is the web-based learning tools.
