Problematic Internet use and Internet gaming disorder: Overlap and relationship with health-related quality of life in adolescents.

General Problematic Internet Use (GPIU) is a dysfunctional use of Internet handling and management in general. In contrast, Internet Gaming Disorder (IGD) is a specific behaviour linked to online videogames. Both problems are becoming common in adolescents, but they have hardly been studied simultaneously, and the joint relationship of the two constructs with Health-Related Quality of Life (HRQoL) is unknown. The general objective of this study is to analyse the relationship between GPIU and IGD and their association with HRQoL. The study is analytical and cross-sectional with 2,024 participants (46.4% boys, n = 939) from 16 schools of 7 Spanish regions. The mean age and standard deviation were 14.20±1.42, with a range of 11-18 years. The Spanish versions of the KIDSCREEN-10, the Revised Generalized and Problematic Internet Use Scale 2 and the Internet Gaming Disorder Scale were used. Of the total sample evaluated, 15.5% of the participants had high levels of GPIU, and 3.3% of video game players presented IGD. The dimensions of GPIU are strongly associated with those of IGD. HRQoL correlated significantly and negatively with all the dimensions of GPIU and IGD (p <,001). Participants who reported problems with GPIU or IGD, individually or conjointly, had significantly lower scores in HRQoL than those with no problems.
