We investigated the relationship of self-sexualization to self-objectification, weight concerns, self-efficacy, academic outcomes, and career aspirations among preadolescent girls. Participants were 89 six- to nine-year-old girls; parental reports were also obtained. Two thirds of girls showed signs of self-sexualization by choosing a sexualized doll over a nonsexualized doll as who they preferred to look like and/or who they currently look like. Girls who self-sexualized reported higher self-objectification and weight concerns than girls who did not self-sexualize. Self-sexualization was unrelated to social, emotional, and academic self-efficacy and to girls' career confidence and interest. However, parents of girls who self-sexualized reported their daughters had lower academic performance and enjoyed school less compared to girls who did not self-sexualize. Additionally, parents of girls who self-sexualized had lower academic expectations for their daughters. It is possible that in preadolescence self-sexualization affects girls' body cognitions and parental expectations without (yet) affecting self-efficacy or academic goals.
