Translation and validation of the Nomophobia Questionnaire in the Italian language: Exploratory factor analysis. L., Argumosa-Villar, L., Boada-Grau, J., Vigil-Colet, A., Yildirim, C., et al. Overall, the NMP-Q-PT showed to be a reliable and valid instrument for measuring nomophobia.Īdawi, M., Bragazzi, N. The NMP-Q-PT presented excellent consistency, construct and discriminant validity, as well as good concurrent and divergent validities. One higher order factor (global nomophobia) with four lower order factors revealed a good fit to the data. Three models were tested through confirmatory factor analysis.

Five hundred participants from the general population (convenience sampling) filled in the NMP-Q-PT, the Smartphone Addiction Scale-Short Version (SAS-SV) and the Depression, Anxiety, and Stress Scales (DASS-21).

The current study intended to adapt the NMP-Q to European Portuguese (NMP-Q-PT) and test its factor structure and psychometric properties. Based on these characteristics, the Nomophobia Questionnaire (NMP-Q) was designed, showing a four-factor structure and good psychometric characteristics. Nomophobia (no mobile phone phobia) can be defined as a situational phobia described by the fear of not having a smartphone available or being incapable of accessing the Internet.
