饮食失调行为——节食、使用泻药、禁食、暴饮暴食——在大学女性中很常见（11-20%）。据记录，患有精神病理学的年轻女性人数有所增加，这被归咎于 Facebook 等社交媒体网站参与度的增加。我们预测，大学年龄女性的 Facebook 强度（例如，在 Facebook 上花费的时间、Facebook 好友的数量以及 Facebook 融入日常生活的程度）、在线外貌比较（即在社交媒体上将自己的外表与他人进行比较）和在线“肥胖谈话”（即负面谈论自己的身体）将与她们的饮食失调行为呈正相关。在一项在线调查中，128 名大学年龄女性（81.3% 白人、6.7% 亚洲人、9.0% 非裔美国人和 3.0% 其他人）完成了一些项目，测量她们的饮食失调、Facebook 强度、在线外貌比较、在线肥胖谈话、体重指数、抑郁、焦虑、完美主义、冲动和自我效能。在回归分析中，Facebook 强度、在线外貌比较和在线肥胖谈话与饮食失调显着且独特地相关，并与协变量结合解释了饮食失调的很大一部分方差 (60%)。然而，较高的 Facebook 强度与饮食失调行为减少相关，而在线外貌比较和在线肥胖谈话则与饮食失调行为增加相关。当对网上外表比较进行统计时，那些支持更大的 Facebook 强度的大学年龄女性不太可能与饮食失调作斗争。 Facebook 的强度可能会给饮食失调带来风险和好处。
Disordered eating behavior—dieting, laxative use, fasting, binge eating—is common in college-aged women (11–20%). A documented increase in the number of young women experiencing psychopathology has been blamed on the rise of engagement with social media sites such as Facebook. We predicted that college-aged women’s Facebook intensity (e.g., the amount of time spent on Facebook, number of Facebook friends, and integration of Facebook into daily life), online physical appearance comparison (i.e., comparing one’s appearance to others’ on social media) and online “fat talk” (i.e., talking negatively about one’s body) would be positively associated with their disordered eating behavior. In an online survey, 128 college-aged women (81.3% Caucasian, 6.7% Asian, 9.0% African-American, and 3.0% Other) completed items, which measured their disordered eating, Facebook intensity, online physical appearance comparison, online fat talk, body mass index, depression, anxiety, perfectionism, impulsivity, and self-efficacy. In regression analyses, Facebook intensity, online physical appearance comparison, and online fat talk were significantly and uniquely associated with disordered eating and explained a large percentage of the variance in disordered eating (60%) in conjunction with covariates. However, greater Facebook intensity was associated with decreased disordered eating behavior whereas both online physical appearance comparison and online fat talk were associated with greater disordered eating. College-aged women who endorsed greater Facebook intensity were less likely to struggle with disordered eating when online physical appearance comparison was accounted for statistically. Facebook intensity may carry both risks and benefits for disordered eating.
