Improved drinking after a 7-year follow-up is associated with improved QoL even when considering other factors such as additional healthcare use and stressful life events. We conclude that QoL can be an additional endpoint in treatment trials.

Purpose of Review Gaming disorder (GD) appears to be associated with self-concept deficits and increased identification with one's avatar. The goal of this literature review is to highlight study findings assessing psychological and neurobiological correlates of self-concept-related characteristics and avatar identification in GD. Recent Findings The review was based on three literature researches on GD: (1) self-esteem, (2) emotional, social, and academic self-concept domains and avatar identification, and (3) neurobiological correlates of self-concept and avatar identification. The results indicate that GD is associated with decreased self-esteem as well as deficits in physical, social, and emotional self-concept domains. A relatively stable relationship between higher avatar identification and GD was reported in addicted gamers. Furthermore, addicted gamers showed increased activation of brain regions associated with Theory-of-Mind processing while contemplating their own avatar. Summary The results point towards impairments in self-concept and increased identification with the virtual gaming character in addicted gamers. This virtual compensation fosters the formation of an idealized self-concept, which grows increasingly distant from their own self-image. Thus, additional empirically based psychological interventions should focus on the development of a realistic self-image by reducing the dysfunctional discrepancy between the ideal self and the real self.
