Abstract: Nomophobia can be defined as a digital age phobia consisting of an excessive fear of being without a smartphone. Nomophobia negatively impacts physical and mental health, particularly in children and adolescents. This study aimed to test the factor structure and psychometric properties of the European Portuguese version of the Nomophobia Questionnaire for Adolescents (NMP-Q-A). Sample 1 comprised 338 adolescents (58.6% girls), with a mean age of 13.55 (SD = 2.07) years old, and was used to examine the factor structure of the NMP-Q-A, its psychometric properties and the association with other constructs. Sample 2 included 193 adolescents (53.9% boys), with a mean age of 13.61 (SD = 0.80) years old and was used to further test the NMP-Q-A factor structure. One higher-order factor with four lower-order factors structure revealed a good fit to the data in both samples. The NMP-Q-A showed good reliability, construct and concurrent validity. Girls showed higher nomophobia. Adolescents showing more nomophobia revealed more smartphone addiction and psychopathological symptoms and lower quality of life. The NMP-Q-A showed to be a valid and reliable measure to be used in clinical and educational settings.
