To translate, adapt and validate the Smartphone Addiction Inventory (SPAI) in a Brazilian population of young adults.
We employed the translation and back-translation method for the adaptation of the Brazilian version SPAI (SPAI-BR). The sample consisted of 415 university students. Data was collected through an electronic questionnaire, which consisted of the SPAI-BR and the Goodman Criteria (gold standard). The retests were carried out 10-15 days after the initial tests with 130 individuals.
The SPAI-BR maintained semantic, idiomatic and conceptual equivalences from the original scale. The Confirmatory Factor Analysis confirmed the One-factor model of the SPAI with good fit indexes (x2 = 767.861, CFI = 0.913, TLI = 0.905, RMSE = 0.061, WRMR = 1.465). The Kuder-Richardson Coefficient showed good internal consistency. The analysis of the ROC curve established an area under the curve of 86.38%. The Intraclass-Correlation Coefficient of 0.926 between the test and the retest demonstrated an excellent temporal stability. The high correlation between SPAI-BR and the Goodman Criteria (rs = 0.750) established the convergent validity.
The SPAI-BR is a valid and reliable tool for the detection of Smartphone Addiction in Brazilian university students.
对智能手机成瘾量表（SPAI）进行翻译、改编并在巴西年轻成年人中进行验证。
我们采用翻译和回译方法改编巴西版SPAI（SPAI - BR）。样本包括415名大学生。通过电子问卷收集数据，问卷包括SPAI - BR和古德曼标准（金标准）。在初始测试10 - 15天后，对130名个体进行了重测。
SPAI - BR在语义、习语和概念上与原始量表保持等效性。验证性因素分析证实了SPAI的单因素模型，拟合指数良好（x2 = 767.861，CFI = 0.913，TLI = 0.905，RMSE = 0.061，WRMR = 1.465）。库德 - 理查森系数显示出良好的内部一致性。ROC曲线分析得出曲线下面积为86.38%。测试与重测之间的组内相关系数为0.926，表明具有出色的时间稳定性。SPAI - BR与古德曼标准之间的高相关性（rs = 0.750）确立了收敛效度。
SPAI - BR是检测巴西大学生智能手机成瘾的有效且可靠的工具。
