“It just Sends the Message that you’re Nothing but your body” a Qualitative Exploration of Adolescent Girls’ Perceptions of Sexualized Images on Social MediaThis qualitative study used in-depth interviews to explore adolescent girls’ perceptions of sexualized images they typically find when using social media.
