Nomophobia Questionnaire: Propriedades Psicométricas para o Contexto Brasileiro

Abstract

Nomophobia is the separation anxiety from smartphone, which can lead to psychosocial problems. The study sought to explore the psychometric parameters of the Nomophobia Questionnaire (NMP-Q) in Brazil. 500 people from the general population of different Brazilian states (Mage=27.84; SDage=8.69), mostly women (67.4%), who were divided into two studies. In the first one, evidence of factorial validity and internal consistency were observed for the 18 items of NMP-Q. In the second study, the tetrafatorial structure (inability to communicate, loss of connection, inability to access information and disclaimer of convenience) was corroborated, with adequate adjustment indicators (CFI=.94, TLI=.93, RMSEA=.08), presenting acceptable reliability coefficients, as well as verifying convergent validity through correlations between NMP-Q factors and smartphone addiction. The results demonstrate evidence of the psychometric adequacy of NMP-Q, which may be a useful tool to understand antecedents and consequents of nomophobia.
