Correlation Studies out-of Chief Details
The latest relationship study from inside the Dining table dos suggests that stress is negatively correlated having personal classification and absolutely synchronised having social nervousness and you can Internet dependency.
Mediated-Moderation Perception Study
To research brand new moderation aftereffect of societal category between fret and you will social anxiety in addition to mediation aftereffect of personal anxiety ranging from worry and teenage Sites dependency, this research known the job away from Ye and you may Wen (2013) to ensure the new Mediated-moderation Design. Basic, the details was indeed canned from the centralization and you may figuring the merchandise identity (stress ? societal class). 2nd, we used a good hierarchical multiple regression to control for sex, levels, or other parameters (Desk step 3).
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.

Further, we use bootstrap estimate strategy to study the latest robustness on the mediation effect. The kinkyads help outcome revealed that 95% count on period try significantly correlated having mediation impression. Stress notably and you can ultimately influenced Internet addiction because of social stress, the fresh new secondary impression try projected becoming 0.thirteen (95% rely on interval [0.10–0.15]), and also the communication between stress and you may social stratum as well as swayed Sites dependency somewhat as a consequence of societal nervousness, the brand new indirect impression is estimated getting 0.02 (95% trust period [0.01–0.03]).
