Relationship Investigation from Fundamental Details
The fresh new correlation research within the Dining table 2 suggests that stress is adversely coordinated with public group and you may positively coordinated having societal stress and you can Internet habits.
Mediated-Moderation Perception Analysis
To research brand new moderation effect of social group between be concerned and you will public stress and also the mediation effectation of public stress ranging from worry and you can teenage Internet sites addiction, this study regarded the work off Ye and you may Wen (2013) to verify the fresh new Mediated-moderation Design. First, most of the variables were canned from the centralization and you will calculating the item identity (fret ? personal class). 2nd, we used a hierarchical numerous regression to control getting gender, grade, or other parameters (Table 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 established men web 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.

Then, we play with bootstrap estimation way to investigation the brand new robustness on the mediation impression. The results showed that 95% count on period was rather correlated with mediation feeling. Be concerned significantly and ultimately influenced Internet sites addiction using personal anxiety, the fresh new secondary impact is actually estimated become 0.13 (95% depend on period [0.10–0.15]), together with communications anywhere between be concerned and you may societal stratum and additionally influenced Web sites addiction notably using public stress, new indirect feeling was estimated to get 0.02 (95% rely on period [0.01–0.03]).
