Over the past decade, smartphones have permeated all domains of adolescents’ everyday lives, with research dominated by “smartphone addiction.” This study compares one of the most used measures of smartphone addiction with a new alternative measure, the Smartphone Pervasiveness Scale for Adolescents (SPS-A), which focuses on the frequency of smartphone use at key social and physiological moments of daily life. A sample of 3,289 Italian high school students was used to validate the two constructs and compare their suitability for research on academic performance. SPS-A was moderately correlated with smartphone addiction, showed measurement invariance (across ethnic origins, parental education, and gender), and negatively predicted language and math test scores. SPS-A is a nonpathologizing instrument suitable for analyzing the role of smartphone use in academic achievement in combination with students’ social backgrounds.

在过去的十年中，智能手机已经渗透到青少年日常生活的各个领域，研究主要是“智能手机成瘾”。本研究将最常用的智能手机成瘾量表之一与新的替代量表——青少年智能手机普及量表 (SPS-A) 进行比较，后者侧重于智能手机在日常生活的关键社交和生理时刻的使用频率。使用 3,289 名意大利高中生的样本来验证这两种结构并比较它们对学习成绩研究的适用性。SPS-A 与智能手机成瘾呈中度相关，显示出测量不变性（跨种族、父母教育和性别），并负面预测语言和数学考试成绩。
