PURPOSE
Body dissatisfaction is ubiquitous in our society and leads to eating disorders. Longitudinal research suggests that higher body dissatisfaction predicts higher negative affect and unhealthy weight control behaviors over time. However, no study has assessed how body dissatisfaction impacts affect and weight control behaviors in the moment. In the current study, we examined the momentary relationships between body dissatisfaction, affect and weight control behaviors using ecological momentary assessment.
METHODS
Female college students (N = 67) completed measures of state body dissatisfaction, affect, and weight control behaviors across fourteen days using ecological momentary assessment.
RESULTS
Greater body dissatisfaction significantly predicted lower subsequent positive affect and higher subsequent negative affect, but positive and negative affect did not predict subsequent body dissatisfaction. Daily average body dissatisfaction was not significantly associated with daily engagement in either healthy or unhealthy weight control behaviors.
CONCLUSION
Short-term negative effects of body dissatisfaction on affect were apparent. Targeting body dissatisfaction may be important for improving affect.
LEVEL OF EVIDENCE
Level IV, multiple time series without intervention.
目的
在我们的社会中，身体不满是普遍存在的，会导致饮食失调。纵向研究表明，较高的身体不满会随着时间的推移预测更高的负面情绪和不健康的体重控制行为。然而，尚无研究评估身体不满如何影响当下的情绪和体重控制行为。在本研究中，我们使用生态瞬时评估来检查身体不满、情绪和体重控制行为之间的瞬时关系。
方法
女大学生（N=67）在十四天内使用生态瞬时评估完成了状态身体不满、情绪和体重控制行为的测量。
结果
更大的身体不满显著预测了随后较低的积极情绪和较高的负面情绪，但积极和负面情绪并没有预测随后的身体不满。每日平均身体不满与每日参与健康或不健康的体重控制行为均无显著关联。
结论
身体不满对情绪的短期负面影响显而易见。针对身体不满可能对改善情绪很重要。
证据水平
无干预的四级，多个时间序列。
