The objective of this study was to adapt and identify the psychometric properties of the Smartphone Addiction Inventory (SPAI) among adolescents. The participants (N = 310; M = 13.1; SD = 1.22) completed the following instruments: the Internet Addiction Test (IAT), the Smartphone Addiction Scale-Short Version (SAS-SV), and the Brazilian version of the Smartphone Addiction Inventory (SPAI-BR). The prevalence of problematic smartphone use (PSU) was 56.1%. The SPAI-BR presented good internal consistency (α = .88) and reliable temporal stability values (intraclass correlation coefficient = .83). Confirmatory factor analysis (CFA) did not reveal a good factor fit (CFI = .88; TLI = .87). However, exploratory factor analysis (EFA) presented a model with 26 items and four factors. The network analysis (NA) indicated that the items related to compulsive use had higher centrality levels. The ideal cutoff score of the SPAI-BR was 10, and the scale displayed moderate correlations with the SAS-SV and IAT. This study is the first to evaluate the psychometric properties of the SPAI among adolescents. The data indicate that SPAI-BR is reliable for use in this population.

这项研究的目的是适应和确定青少年的智能手机成瘾量表（SPAI）的心理测量特性。参与者（N  = 310; M  = 13.1; SD = 1.22）完成了以下测试：互联网成瘾测试（IAT），智能手机成瘾量表－精简版（SAS-SV）和巴西版本的智能手机成瘾量表（SPAI-BR）。有问题的智能手机使用（PSU）的患病率为56.1％。SPAI-BR具有良好的内部一致性（α= .88）和可靠的时间稳定性值（类内相关系数= .83）。验证性因子分析（CFA）并未显示出良好的因子拟合（CFI = .88; TLI = .87）。但是，探索性因素分析（EFA）提出了一个包含26个项目和四个因素的模型。网络分析（NA）表明，与强迫使用有关的项目具有较高的集中度。SPAI-BR的理想截断得分是10，并且该量表显示出与SAS-SV和IAT的适度相关性。这项研究是第一个评估青少年中SPAI的心理测量特性的方法。数据表明SPAI-BR在该人群中使用是可靠的。
