This study examined: frequency of upward and downward body, eating, and exercise comparisons; context in which these comparisons occur; and body, eating, and exercise comparison direction as predictors of concurrent body dissatisfaction and disordered eating thoughts, urges, and behaviors in college women's everyday lives using ecological momentary assessment (EMA).
Participants were 232 college women who completed a two-week EMA protocol, using their personal electronic devices to answer questions three times per day.
First, body, eating, and exercise comparisons were common. Second, when these comparisons were made, they were typically upward. Third, body comparisons were most oftentimes made about weight and shape and eating comparisons about healthiness and amount of food. Exercise comparisons were made on a wider variety of dimensions. Fourth, most body and eating comparisons were made with strangers and close friends, respectively, while exercise comparisons were made with a variety of individuals. Upward comparisons were usually made with acquaintances and strangers. Fifth, results shed light on where college women compare themselves. Sixth, upward comparisons were found to have negative consequences, and downward comparisons were generally not found to have a buffering effect on eating pathology.
Results suggest targeting not only body but also eating and exercise comparisons in intervention. Also, prevention/intervention approaches should not promote engagement in downward comparisons, as they were not found to be protective and were even harmful at times. Clinicians should be attuned to the categories on which, with whom, and where college women are most likely to compare.
本研究考察了:身体向上和向下比较、饮食比较以及运动比较的频率;这些比较发生的情境;以及身体、饮食和运动比较方向作为预测大学女生日常生活中同时存在的身体不满以及饮食失调想法、冲动和行为的指标,采用生态瞬时评估(EMA)方法。
参与者为232名大学女生,她们完成了一项为期两周的EMA方案,使用个人电子设备每天回答三次问题。
首先,身体、饮食和运动比较很常见。其次,当进行这些比较时,通常是向上比较。第三,身体比较大多是关于体重和体型,饮食比较是关于健康程度和食物量。运动比较涉及更广泛的维度。第四,大多数身体和饮食比较分别是与陌生人及亲密朋友进行的,而运动比较是与各种不同的人进行的。向上比较通常是与熟人及陌生人进行的。第五,研究结果揭示了大学女生在哪些方面进行自我比较。第六,发现向上比较有负面后果,而向下比较一般未被发现对饮食病理有缓冲作用。
研究结果表明,干预措施不仅应针对身体比较,还应针对饮食和运动比较。此外,预防/干预方法不应鼓励进行向下比较,因为未发现其具有保护作用,甚至有时是有害的。临床医生应留意大学女生最有可能在哪些类别、与谁以及在何处进行比较。
