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 eating 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.
饮食紊乱行为——节食、使用泻药、禁食、暴饮暴食——在大学年龄段女性中很常见(11%-20%)。有记录表明,经历饮食心理病理学的年轻女性数量增加,这被归咎于诸如脸书等社交媒体使用的增多。我们预测,大学年龄段女性的脸书使用强度(例如,花在脸书上的时间、脸书好友数量以及脸书融入日常生活的程度)、在线外貌比较(即在社交媒体上与他人比较自己的外貌)以及在线“胖语”(即负面谈论自己的身材)将与她们的饮食紊乱行为呈正相关。
在一项在线调查中,128名大学年龄段女性(81.3%为白种人,6.7%为亚洲人,9.0%为非裔美国人,3.0%为其他种族)完成了一些项目,这些项目测量了她们的饮食紊乱、脸书使用强度、在线外貌比较、在线“胖语”、体重指数、抑郁、焦虑、完美主义、冲动性和自我效能感。
在回归分析中,脸书使用强度、在线外貌比较和在线“胖语”与饮食紊乱显著且独特相关,并且与协变量一起解释了饮食紊乱中很大比例的方差(60%)。然而,更高的脸书使用强度与饮食紊乱行为减少相关,而在线外貌比较和在线“胖语”都与更严重的饮食紊乱相关。
在对在线外貌比较进行统计学调整后,认可更高脸书使用强度的大学年龄段女性饮食紊乱的可能性较小。脸书使用强度可能对饮食紊乱既有风险也有益处。
