Relationship Studies regarding Fundamental Parameters
The newest relationship data inside the Dining table 2 implies that stress is negatively synchronised with social class and you can surely coordinated with social nervousness and you will Web sites dependency.
Mediated-Moderation Perception Investigation
To analyze the fresh moderation effectation of personal group between fret and you may public anxiety in addition to mediation effectation of social stress ranging from worry and teenage Internet habits, this study regarded the work away from Ye and you can Wen (2013) to verify the new Mediated-moderation Design. Basic, every details was processed by the centralization and you can calculating the merchandise name (worry ? personal category). Next, we put an excellent hierarchical several regression to manage having sex, levels, or any other details (Desk 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.
Figure 1. A mediated-moderation model. Factor loadings are standardized. ? p < 0.05, ?? p < 0.01, ??? p < 0.001.
Next, we explore bootstrap estimate strategy to study the fresh new robustness from the mediation perception. The outcomes revealed that 95% believe period is significantly coordinated with mediation impact. Be concerned somewhat and indirectly swayed Internet sites habits using societal anxiety, the latest secondary feeling was estimated to be 0.thirteen (95% confidence period [0.10–0.15]), and also the interaction ranging from fret and you will personal stratum and additionally swayed Internet habits significantly by way of personal anxiety, the indirect effect is estimated are 0.02 (95% depend fling profili on interval [0.01–0.03]).
