The prevalence of mobile phone addiction among adolescents is a growing concern with significant implications for psychological well-being and academic performance. The mediating role of academic anxiety (AA) in the relationship between self-control (SC) and mobile phone addiction (MPA) among middle school students deserves thorough investigation, particularly considering the significant moderating effect of Being an only child on these relationships.
A cross-sectional survey of 2,489 middle school students (1,257 girls and 1,232 boys) assessed SC, AA, and MPA. SC was measured using the Self-Control Scale, AA with the Academic Anxiety Scale (AAS), and MPA with the Mobile Phone Addiction Index (MPAI). Structural equation modeling analyzed the mediating and moderating effects.
Self-control significantly negatively predicted AA ( = -0.464, < 0.001) and MPA ( = -0.563, < 0.001). AA was identified as a significant mediator that positively predicted MPA ( = 0.173, < 0.001) and mediated the relationship between SC and MPA ( = 0.081, 95%CI = [-0.10, -0.06]). The moderating effect of being an only child on the relationship between AA and MPA ( = -0.13, < 0.001) was significant.
The empirical evidence substantiates the mediating role of AA in the relationship between SC and MPA, while simultaneously demonstrating that only children exhibit heightened susceptibility to MPA with increasing AA levels. Such observations significantly advance our understanding of the influence of family dynamics on MPA manifestation among adolescents.
青少年手机成瘾的患病率日益受到关注，对心理健康和学业成绩具有重大影响。学业焦虑（AA）在中学生自我控制（SC）与手机成瘾（MPA）关系中的中介作用值得深入研究，尤其是考虑到独生子女身份对这些关系的显著调节作用。
对2489名中学生（1257名女生和1232名男生）进行横断面调查，评估SC、AA和MPA。使用自我控制量表测量SC，用学业焦虑量表（AAS）测量AA，用手机成瘾指数（MPAI）测量MPA。采用结构方程模型分析中介和调节效应。
自我控制显著负向预测AA（β = -0.464，p < 0.001）和MPA（β = -0.563，p < 0.001）。AA被确定为显著的中介变量，正向预测MPA（β = 0.173，p < 0.001），并介导SC与MPA之间的关系（β = 0.081，95%CI = [-0.10, -0.06]）。独生子女身份对AA与MPA关系的调节效应显著（β = -0.13，p < 0.001）。
实证证据证实了AA在SC与MPA关系中的中介作用，同时表明独生子女随着AA水平的升高对MPA表现出更高的易感性。这些观察结果显著推进了我们对家庭动态对青少年MPA表现影响的理解。
