Abstract: Smartphones now are very popular worldwide and have become an important part in our daily life. However, the excessive use of smartphone may result in smartphone addiction, and consequently lead to a series of negative outcomes. Notably, adolescence is the key period of individual development, and smartphone addiction have negative effects on adolescents’ physiological and development. To better prevent and intervene adolescent smartphone addiction, it is critical to explore the potential risk factors and underlying smartphone addiction. With development of digital technology, technology has already integrated into family life. Therefore, it is common for the interruptions in interaction due to using technology. Prior researchers has referred this phenomenon as “technoference” or “technology interference”. Recently, studies have found that technoference in parent-child interaction that is parent-child interaction is interrupted by parents’ using technology was an important risk factor for child or adolescent behavioral problems. However, few studies examine the relation between technoference in parent-child interaction and adolescent smartphone addiction. Also, according to the cognitive-behavioral model of pathological internet use, core self-evaluations may mediate the relation between technoference in parent-child interaction and adolescent smartphone addiction. Specifically, parent-child technoference may increase the risk of adolescent smartphone addiction through decreased core self-evaluations. In addition, based on compensatory satisfaction theory of pathological internet use, technoference in parent-child interaction may mediate the relation between technoference in parent-child interaction and adolescent smartphone addiction. In detail, technoference in parent-child interaction may increase the risk of adolescent smartphone addiction through increased need satisfaction perceived online. The present study aims to investigate the effects of technoference in parent-child interaction on adolescent smartphone addiction, and further explore the mediating effects of core self-evaluations and need satisfaction perceived online. A sample of 4372 students (49.68% males; Mage = 14.01 years, SD = 1.67) completed Technology Interference in Life Examples Scale, Core Self-Evaluation Scale, Online Basic Psychological Need Satisfaction Scale, and Smartphone Addiction Scale for College Students, SPSS 21.0 and SPSS macro PROCESS were used to manage and analyse data, and bias-corrected percentile bootstrap method was used to examine the mediating effects of core self-evaluations and need satisfaction perceived online. The results indicated that: (1) Technoference in parent-child interaction positively predicted adolescent smartphone addiction. (2) Core self-evaluations mediated the relation of technoference in parent-child interaction to adolescents’ smartphone addiction. Specifically, technoference in parent-child interaction negatively predicted adolescent smartphone addiction (β = -.30, p < .001). (3) Need satisfaction perceived online mediated the relation between technoference and adolescent smartphone addiction. Specifically, technoference positively predicted need satisfaction perceived online (β = -.20, p < .001), and need satisfaction perceived online positively predicted adolescents’ smartphone addiction (β = -.34, p < .001). These findings highlighted the negative effect of technoference in parent-child interaction on adolescent smartphone addiction. The results also revealed the underlying mechanism of how technoference in parent-child interaction influence adolescent smartphone addiction. Moreover, the present study extended previous researches and provided empirical implications for the prevention and intervention of adolescent smartphone addiction. Based on the present study, it is extremely important to apply technology devices healthily to family life, cultivate adolescents to form correct self-evaluation and fully satisfy adolescents’ psychological needs in real life.

摘要： 采用问卷调查法，以4372名中学生为研究对象，考察核心自我评价和心理需求网络满足在亲子间科技干扰与青少年智能手机成瘾之间的中介作用。结果表明：（1）亲子间科技干扰可显著正向预测青少年智能手机成瘾；（2）在控制了性别、年龄之后，科技干扰可分别通过核心自我评价和心理需求网络满足间接地影响青少年智能手机成瘾。
