This study presents a contribution to the Italian validation of the Brief Multicultural Version of the Test of Mobile Phone Dependence (TMDbrief) on a sample of Italian adolescents. TMDbrief is a scale of 12 items measuring four dimensions: abstinence, abuse, tolerance, lack of control. A sample of 442 adolescents (Age: M = 14.37; Gender: males, 23.6%) answered a questionnaire on the usage of digital media including the TMDbrief and two items on the frequency of mobile phone and Internet use. TMDbrief showed good construct validity and its applicability in the Italian context. Additionally, this scale can be used for research projects, prevention and educational interventions on the usage of new technologies.
