Abstract：
OBJECTIVE: Appearance focused self-concept (i.e., overvaluing the importance of appearance for self-definition and self-worth) is theorized to predict dietary restraint and binge eating in the short-term (e.g., daily life). Yet, no research has examined whether appearance focused self-concept increases within-persons during a day and if such increases are linked to greater dietary restraint and binge eating for that day. We addressed this gap in knowledge.
METHODS: Sixty-three female university students completed four items from the Beliefs About Appearance Scale as a measure of appearance focused self-concept six times per day (9 am, 11 am, 1 pm, 3 pm, 5 pm, and 7 pm) for 14 days. Daily at 9 pm, they completed measures of dietary restraint and binge eating for that day.
RESULTS: Analyzing data from 555 days, latent growth curve analyses revealed a small-to-moderate linear increase in appearance focused self-concept from 9 am to 3 pm that plateaued from 3 to 7 pm. A more rapid linear increase in appearance focused self-concept from 9 am to 3 pm was associated with greater binge-eating frequency during that day, but not with dietary restraint. The findings were observed when adjusting for between-day appearance focused self-concept at 9 am, which was positively associated with dietary restraint and binge-eating frequency.
CONCLUSIONS: Findings are discussed in relation to research on appearance focused self-concept as a risk factor for disordered eating. Findings are also discussed in relation to how sociocultural factors may increase appearance focused self-concept over time. Future research should delve into the within-day dynamic interplay between appearance focused self-concept and disordered eating.
UNASSIGNED: Our study revealed a noteworthy increase in the importance women attach to their appearance over the course of a day, correlating with increased binge eating during that day. Additionally, heightened appearance importance at the onset of a day was associated with more dietary restraint and binge eating during that day. These findings suggest a shorter timescale for the connection between appearance importance and disordered eating than previously understood.

摘要：
目标：以外观为中心的自我概念(即高估外观对自我定义和自我价值的重要性)被理论上用来预测短期内的饮食限制和暴饮暴食(例如，日常生活)。然而，没有研究调查以外表为中心的自我概念在一天内是否会增加，以及这种增加是否与当天更多的饮食限制和暴饮暴食有关。我们解决了这一知识差距。
方法：63名女大学生每天六次完成“关于外表的信念量表”中的四项内容，以衡量以外表为中心的自我概念（上午9点，上午11点，下午1点,下午3点,下午5点，和下午7点)持续14天。每天晚上9点，他们完成了当天的饮食限制和暴饮暴食措施。
结果：分析555天的数据，潜在生长曲线分析显示，从上午9点至下午3点，以外观为中心的自我概念呈线性增加，从下午3点至7点趋于稳定。从上午9点至下午3点，以外观为中心的自我概念的线性增加与当天暴饮暴食的频率增加有关，但不能限制饮食。在上午9点调整以白天外观为中心的自我概念时，观察到了这些发现，这与饮食限制和暴饮暴食频率呈正相关。
结论：关于以外表为中心的自我概念作为饮食失调的危险因素的研究，讨论了研究结果。还讨论了有关社会文化因素如何随着时间的推移增加以外表为中心的自我概念的发现。未来的研究应该深入研究以外表为中心的自我概念和无序饮食之间的日常动态相互作用。
我们的研究表明，女性在一天中对外表的重视程度显着增加，与那一天暴饮暴食增加有关。此外,在一天开始时增加的外观重要性与当天更多的饮食限制和暴饮暴食有关。这些发现表明，外观重要性与饮食失调之间的联系时间比以前理解的要短。
