Digital socialization effects refer to the changes in individuals’ social, psychological, behavioral, and developmental characteristics associated with participation in digitally mediated socialization processes [1]. These effects may arise as individuals use digital technologies to interact with others, acquire social norms and values, develop relationships, construct identities, and participate in online communities [1][2]. They may involve changes in social connectedness, communication patterns, digital competencies, self-concept, emotional experiences, and behavioral norms [2][3]. Digital socialization effects can extend across online and offline contexts because digitally mediated interactions may influence face-to-face relationships, social participation, and everyday behavior [3]. Their direction and magnitude may vary according to the characteristics of digital environments, patterns of technology use, developmental stage, social context, and individual characteristics [2][3][4]. The concept therefore encompasses both potentially beneficial and adverse outcomes associated with digitally mediated socialization.
