Friendships in the digital age are explored in the third section, covering adolescent friendships, relational maintenance, grief and loss, and networked interactions. The final section shifts the perspective to family dynamics, spotlighting parent-adolescent communication patterns, parental mediation of children's social media use, and the unique social support networks built by mothers online. lt Social Media and Close Relationships is the ideal text for courses and programs in communication, media studies, family studies, psychology, and sociology.
