The Generalized Problematic Internet Use Scale 2 in a Polish sample: psychometric validation and relationship with specific Internet-related disorders and psychosocial functioning.

Problematic Internet use is a multidimensional construct rather than a one-dimensional construct with strong but not overlapping positive relations with the other specific Internet-related disorders. Those relationships are especially strong among problematic activities related to the social context of Internet use. Furthermore, our findings prove the theoretical assumptions that psychosocial problems and poor social skills are related to problematic Internet use.
