Correlation Data regarding Chief Parameters
Brand new relationship research for the Dining table dos signifies that be concerned is adversely correlated which have public class and you will positively synchronised with public nervousness and you may Internet sites dependency.
Mediated-Moderation Impact Research
To investigate the fresh moderation effectation of public category between stress and personal anxiety as well as the mediation effect of societal anxiety ranging from be concerned and you can adolescent Websites dependency, this research referred to the job from Ye and you will Wen (2013) to verify the newest Mediated-moderation Model. Basic, the parameters had been canned from the centralization and you may calculating this product name (worry ? personal group). 2nd, we put a good hierarchical several regression to manage for gender, grade, or any other variables (Table step 3).
In mennation telefon numarası 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.

Subsequent, i have fun with bootstrap estimation technique to study the fresh robustness regarding the mediation perception. The outcomes showed that 95% trust period was notably correlated with mediation impression. Stress rather and you may indirectly swayed Sites addiction courtesy societal nervousness, this new indirect impact are estimated becoming 0.13 (95% rely on period [0.10–0.15]), and telecommunications between fret and you will public stratum along with influenced Internet dependency rather owing to public stress, the fresh new secondary perception is actually estimated to-be 0.02 (95% trust interval [0.01–0.03]).
