Abstract

This study performed a cross-cultural adaptation and identified validity evidences of the smartphone addiction scale-long version (SAS-LV) in a sample of Brazilian university students (n = 504; Mage = 21.7; SD = 3.03) and adults (n = 578; Mage = 37.8; SD = 11.8). The adaptation of the SAS-LV was performed based on specific protocols, with the participation of experts in the field. The factorial structure was evaluated by using confirmatory factor analysis (CFA), principal component analysis (PCA), and network analysis (NA). The CFA did not detect adequate parameters, but the PCA presented a five-factor solution, explaining 55.2% of the variance. All items from the original version were retained because they had a factor load above 0.3. The SAS-LV presented good reliability indexes (α =.93). The NA indicated that the instrument had good psychometric properties for the two populations studied. The Portuguese version of the SAS-LV presented good validity indexes and can be used as a screening tool for smartphone addiction. Este estudo realizou a adaptação transcultural e identificou evidências de validade da smartphone addiction scale-long version (SAS-LV) para uma amostra de universitários (n = 504; Midade = 21,7; DP = 3,03) e adultos (n = 578; Midade = 37,8; DP = 11,8) brasileiros. A adaptação da SAS-LV foi realizada a partir de protocolos específicos, com a participação de especialistas da área. A estrutura fatorial foi avaliada pela análise fatorial confirmatória (AFC), análise de componentes principais (ACP) e análise de rede (AR). A AFC não apresentou parâmetros adequados, mas a ACP apresentou uma solução com cinco fatores, explicando 55,2% da variância. Todos os itens da versão original foram mantidos porque apresentaram carga fatorial acima de 0,3. A SAS-LV apresentou bons índices de confiabilidade (α = 0,93). A AR indicou um bom ajuste psicométrico do instrumento para as duas populações estudadas. A versão em português da SAS-LV apresentou bons índices de validade, podendo ser utilizada como instrumento de rastreio para a dependência de smartphone.
