随着科技的发展，手机依赖的现象已经越来越普遍。本研究力图证明父母使用手机中的低头行为对青少年手机依赖行为的预测作用，并探索其中的作用路径。基于计划行为理论和社会学习理论，我们假设感知到父母的主观规范和手机依赖意图在其中起到中介作用。本研究通过问卷测验在北京某中学收集了605名中学生的问卷数据，测量了父母的低头行为、主观规范、手机依赖意图、手机依赖行为四个变量。结果表明，父母低头行为能够显著正向预测青少年的手机依赖水平，并且通过两条途径产生作用：一种是父母低头行为本身会对手机依赖行为产生助长作用，即通过直接作用；另一种是通过两条路径实现间接作用:1)父母低头增加个体手机依赖的行为意图，增加手机依赖水平，2)父母低头使个体感知源自父母更多手机依赖倾向的主观规范，增加个体手机依赖意图，恶化手机依赖行为。整个模型拟合效果较好，χ2(5)=5.965, CFI=.994, TLI=.989, RMSEA (90% CI)=.018 [.000,.062].由此我们得出结论，父母低头能够显著预测并影响青少年的手机依赖行为，其中，父母低头行为通过影响个体手机依赖的行为意图，影响手机依赖行为。同时，父母低头还会影响青少年感知到源自父母的手机依赖倾向的主观规范，并通过其影响手机依赖意图产生链式中介作用，进一步影响个体的手机依赖行为。

Mobile phone dependency has become common phenomena in nowadays. To verify the effects of parental phubbing on teenager’s mobile phone using, along with the mechanism in this relationship, the mediation roles of subjective norm and mobile phone dependency are hypothesized under the support Ajzen’s theory of protection behaviors and Bandura’s social learning theory. The present study has collected questionnaires from 605 middle school students in Beijing, China, to measure their scores of parental pubbing behaviors using adapted Partner Phubbing Scale. The perceived parental mobile phone dependency norm and mobile phone dependency intention was measured by adapted online Technology Acceptance Model. Mobile phone dependency behaviors were assessed by Mobile Dependency Scale. The results revealed the predictive ability of parental phubbing on mobile phone dependency and the mechanism involved in this process. We found that parental phubbing functioned through one direct way in which parental phubbing behaviors increased teenager’s mobile phone dependency behaviors significantly, and two indirect ways: 1) parental phubbing reinforced teenagers’ mobile phone dependency intention, which in turns increased the likelihood of mobile phone dependency; 2) parental phubbing enhanced the tendency of parental mobile phone dependence norm perceived by teenagers, and thus reinforced their mobile phone dependency intention, ultimately increased the possibility of mobile phone dependency. The proposed model were proved to have a good fitness at χ2(5)=5.965, CFI=.994, TLI=.989, RMSEA (90% CI)=.018 [.000,.062]. Therefore, we came to a conclusion that parental phubbing is a significant indicator of mobile phone dependency, and that mobile phone dependency intention played a mediation role between them. In addition, perceived parental mobile phone dependency norm played a mediation role between parental phubbing and mobile phone dependency intention, and influenced the level of mobile phone dependency behaviors indirectly through mediation effect of mobile phone dependency intention.
