The nomophobia (no mobile phone phobia) may be considered a specific phobia characterized by the fear of being without a mobile phone, a smartphone or Internet, inducing a negative impact in the individual’s life. In order to assess this construct, the Nomophobia Questionnaire (NMP-Q) was developed and proved to be a valid and reliable measure. The current study aimed to develop the Portuguese version of the Nomophobia Questionnaire (NMP-Q-PT) and explore its factor structure and psychometric characteristics in the general population.

A sample of 203 participants was recruited at a university and online. Participants completed a sociodemographic questionnaire, the NMP-Q-PT, the Smartphone Admission Scale - Short Version (SAS-SV) and the Depression, Anxiety, and Stress Scales (DASS-21).College students completed the instruments in a paper pencil format and participants recruited online also completed the instruments online.

According to the original version a 4-factor model was tested. Results suggested that defining correlations between items 5 and 6, 17 and 20, 11 and 14 would improve the fit. This second model was tested and fit indexes were: χ2/gl = 2.26; CFI = .945; GFI = .849; RMSEA = .079; MECVI = 2.347. A Cronbach's alpha of .96 was found. Regarding correlations between the NMPQ-PT and the SAS-SV, results showed a positive correlation. Positive correlations were also found between NMP-Q-PT and depressive symptoms, anxiety symptoms and stress symptoms of DASS-21. 
The current study allowed to achieve a Portuguese version of the NMP-Q that showed to be a valid and reliable instrument for the assessment of nomophobia.
