BACKGROUND: The global rise in smartphone addiction among children is linked to increasing mental, physical, familial, and financial problems. This study aimed to longitudinally explore the impact of sibling smartphone addiction on child smartphone addiction. While the influences of parental smartphone addiction and peer groups on smartphone addiction have been studied, more research is needed to examine the longitudinal effects of sibling smartphone addiction, a significant family member during childhood, on child smartphone addiction. METHODS: This study conducted a longitudinal analysis using four years of panel data (2019-2022) from the Korean Children and Youth Panel Survey (KCYPS). The final analysis included a total of 1,978 participants, comprising fourth-grade elementary school children (n=989) and their siblings (n=989). The changes in smartphone addiction over the four years were analyzed using latent growth analysis. RESULTS: First, while the rate of change in child smartphone addiction was higher, both sibling and child smartphone addiction increased over time. Lower initial smartphone addiction levels were linked to a greater increase in smartphone usage over time. These results indicate the need for interventions targeting groups with lower initial levels of smartphone addiction. Second, higher initial levels of sibling smartphone addiction were associated with greater child smartphone addiction, and the change rate of sibling smartphone addiction influenced that of child smartphone addiction. As sibling smartphone addiction sharply increased over time, child smartphone addiction similarly escalated dramatically. On the other hand, it was found that as sibling smartphone addiction increases gradually, child smartphone addiction also increases gradually. CONCLUSION: This study identified the longitudinal impact of sibling smartphone addiction on the onset and progression of child smartphone addiction. The findings suggest that when preventing and intervening in the risk of child smartphone addiction, it is effective to consider the issue of sibling smartphone addiction in a long-term context.
背景：全球儿童智能手机成瘾现象的增多与精神、身体、家庭和经济问题的增加有关。本研究旨在纵向探究兄弟姐妹智能手机成瘾对儿童智能手机成瘾的影响。虽然父母智能手机成瘾和同伴群体对智能手机成瘾的影响已得到研究，但仍需更多研究来考察兄弟姐妹智能手机成瘾（童年时期重要的家庭成员）对儿童智能手机成瘾的纵向影响。 方法：本研究利用韩国儿童和青少年面板调查（KCYPS）四年的面板数据（2019 - 2022年）进行纵向分析。最终分析共纳入1978名参与者，包括小学四年级学生（n = 989）及其兄弟姐妹（n = 989）。使用潜在增长分析来分析四年间智能手机成瘾情况的变化。 结果：首先，虽然儿童智能手机成瘾的变化率更高，但兄弟姐妹和儿童的智能手机成瘾情况均随时间增加。较低的初始智能手机成瘾水平与随着时间推移智能手机使用量的更大增加相关。这些结果表明需要针对初始智能手机成瘾水平较低的群体进行干预。其次，兄弟姐妹较高的初始智能手机成瘾水平与儿童更高的智能手机成瘾相关，且兄弟姐妹智能手机成瘾的变化率影响儿童智能手机成瘾的变化率。随着兄弟姐妹智能手机成瘾随时间急剧增加，儿童智能手机成瘾也同样急剧上升。另一方面，研究发现随着兄弟姐妹智能手机成瘾逐渐增加，儿童智能手机成瘾也逐渐增加。 结论：本研究确定了兄弟姐妹智能手机成瘾对儿童智能手机成瘾的发生和发展的纵向影响。研究结果表明，在预防和干预儿童智能手机成瘾风险时，从长期角度考虑兄弟姐妹智能手机成瘾问题是有效的。
