Relationship Analysis regarding Main Parameters
The new relationship investigation during the Dining table dos shows that be concerned was adversely coordinated which have personal classification and you will undoubtedly correlated having public anxiety and you can Internet addiction.
Mediated-Moderation Feeling Investigation
To analyze the fresh new moderation effect of personal class ranging from stress and you may societal anxiety additionally the mediation effectation of social stress anywhere between worry and teenage Websites dependency, this study referred to the job away from Ye and you will Wen (2013) to ensure the Mediated-moderation Model. First, all the parameters was basically canned by the centralization and you can figuring the product identity (be concerned ? personal class). Next, we used good hierarchical numerous regression to control to have gender, degree, or other variables (Dining 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 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 0.90, the structural equation model is established. In this study, the model fit the data well, which confirmed the mediated-moderation model.

Next, we have fun with bootstrap quote strategy to study brand new robustness on the mediation effect. The outcomes indicated that 95% trust period was notably correlated having mediation impression gaydar. Stress rather and you can indirectly swayed Sites dependency using social stress, new secondary perception are estimated getting 0.13 (95% believe period [0.10–0.15]), and communications anywhere between worry and you may societal stratum and influenced Web sites addiction notably owing to public anxiety, brand new secondary feeling try estimated as 0.02 (95% confidence interval [0.01–0.03]).
