Correlation Research off Chief Parameters
The newest relationship research from inside the Desk 2 means that worry was adversely synchronised that have public group and you will surely synchronised with personal nervousness and you may Websites habits.
Mediated-Moderation Impact Investigation
To research the newest moderation effectation of personal class anywhere between fret and you can societal stress and mediation effectation of personal stress ranging from worry and adolescent Web sites addiction, this study labeled the job of Ye and you will Wen (2013) to ensure the fresh new Mediated-moderation Design. Basic, all details was in fact canned by centralization and figuring the item label (be concerned ? public category). Second, i used a beneficial hierarchical several regression to control having sex, levels, and other parameters (Desk step three).
In the first step, we used a stepwise entry method to calculate the regression of Internet addiction to stress and social class (the moderator) and stress ? social class. The results showed that the regression coefficient of stress ? social class was significant (? = 0.06, p < 0.01), which means that social class plays a significant role in moderating the relationship between stress and Internet addiction.
In the second step, we again used a stepwise entry method to calculate the regression of social anxiety to stress; social class and stress ? social class. The results showed that the coefficient of stress ? social class is also significant (? = 0.06, p < 0.01), which means that social class plays a significant role in moderating the relationship between stress and social anxiety. Whatever the status, the stress perceived by adolescents had a significant predictive effect on social anxiety according to simple slope testing. Furthermore, with the stress from low to high, the anxiety levels adolescents perceived was higher in the low social class (b = 0.27, t = 3.96, p < 0.001) than that of adolescents in the high social class (b = 0.48, t = 9.76, p < 0.001).
Lastly, in the third step, we used a stepwise entry method to calculate the regression of Internet addiction to stress and social class; social anxiety and stress ? social class. It showed that the explanatory power of the product term to Internet addiction decreases and that the regression coefficient of social anxiety was significant (? = 0.30, p < 0.001). However, the results were still significant (? = 0.04, p < 0.05), which indicates that social anxiety partially mediates the moderation of social class on stress and Internet addiction, and the indirect moderating effect accounted for 16.7% of the total moderating effect.
To test the mediated-moderation effect more thoroughly, we constructed an equation model with stress, social class, stress ? social class, social anxiety, and Internet addiction as observable variables (Figure 1). The results showed that ?2/df = 4.98, RMSEA = 0.049, SRMR = 0.024, CFI = 0.991, GFI = 0.998, and TLI = 0.957. In general, if ?2/df > 3.84, RMSEA < 0.08, SRMR < 0.05, CFI/GFI/TLI > 0.90, the structural equation model is established. In this study, the model fit the data well, which confirmed the mediated-moderation model.

After that, we have fun with bootstrap estimation way to analysis new robustness on the mediation impression. The outcome revealed that 95% depend on interval is actually somewhat synchronised which have mediation effect. Be concerned significantly and you can indirectly influenced Internet dependency courtesy societal anxiety, the fresh new secondary perception was projected to-be 0.thirteen (95% trust interval [0.10–0.15]), as well as the telecommunications anywhere between stress and you will social stratum plus swayed Websites habits rather through personal anxiety, the newest indirect effect try projected to be 0.02 (95% confidence period [0.01–0.03]).
