This prospective, longitudinal study examined associations between whether and when children first acquire a mobile phone and their adjustment measures, among low-income Latinx children. Children (N = 263; 55% female; baseline M = 9.5) and their parents were assessed annually for 5 years from 2012. Children first acquired a mobile phone at a mean (SD) age of 11.62 (1.41) years. Pre-registered multilevel models tested associations linking phone ownership, phone acquisition age, and the interaction between ownership and acquisition age to levels and changing trends of depressive symptoms, school grades, and reported and objectively assessed sleep. Results showed no statistically significant associations, controlling the False Discovery Rate. Findings suggest an absence of meaningful links from mobile phone ownership and acquisition age to child adjustment.
这项前瞻性纵向研究考察了低收入拉丁裔儿童首次获得手机的时间及其与调整措施之间的关联。2012 年起，对 263 名儿童（55%为女性；基线 M=9.5）及其父母进行了为期 5 年的年度评估。儿童首次获得手机的平均年龄（标准差）为 11.62（1.41）岁。预先注册的多层次模型测试了与手机拥有、手机获得年龄以及所有权与获得年龄之间的相互作用相关的关联，以评估抑郁症状、学校成绩以及报告和客观评估的睡眠水平和变化趋势。结果显示，在控制虚假发现率的情况下，这些关联没有统计学意义。研究结果表明，手机拥有和获得年龄与儿童适应能力之间没有明显的联系。
