Extensive support exists for objectification theory's original aim of explaining patterns of women's mental health risk through a sociocultural lens. One pathway in objectification theory proposes a mediational role of body shame in the relationship between self-objectification and eating disorder (ED) pathology. Robust past cross-sectional research supports this proposed pathway, but largely in non-Hispanic Caucasian, college-aged samples; this pathway has yet to be empirically demonstrated longitudinally. Given previously documented concerns regarding direct measurement of body shame, we tested two measures of body shame as mediators in both cross-sectional and longitudinal models in a diverse sample of adult women.
Utilizing snowball sampling via email, we recruited age and racially/ethnically diverse women predominantly within the United States. Participants completed online surveys assessing self-objectification (operationalized as body surveillance), body shame, and ED pathology at baseline, 3-months and 6-months.
Racial/ethnic minority ( = 139) and non-Hispanic Caucasian ( = 181) adult women completed the measures. Cross-sectional moderated mediation models indicated that racial/ethnic status did not moderate relationships, and that body shame significantly mediated the relation between body surveillance and ED pathology at each time point. The longitudinal model, analyzed using cross-lagged panel analyses, was nonsignificant, as body surveillance failed to predict future body shame when controlling for past body shame.
Racial/ethnic status did not moderate relations at any time point. Cross-sectional findings replicated past research; the longitudinal model did not support a core mediation pathway linking self-objectification to ED pathology through body shame. Because self-objectification putatively develops earlier in life, future research also should examine these relations in younger diverse samples over a longer time period.
客观化理论最初旨在通过社会文化视角解释女性心理健康风险模式,对此存在广泛支持。客观化理论中的一条途径提出,身体羞耻感在自我客观化与饮食失调(ED)病理之间的关系中起中介作用。过去大量的横断面研究支持了这一途径,但主要是在非西班牙裔白人、大学年龄段的样本中;这一途径尚未通过纵向研究得到实证证明。鉴于先前记录的对身体羞耻感直接测量的担忧,我们在成年女性的多样化样本中,在横断面和纵向模型中测试了两种身体羞耻感测量方法作为中介变量。
通过电子邮件利用滚雪球抽样法,我们主要在美国招募了年龄和种族/族裔多样化的女性。参与者在基线、3个月和6个月时完成在线调查,评估自我客观化(定义为身体监测)、身体羞耻感和饮食失调病理。
种族/族裔少数群体(n = 139)和非西班牙裔白人(n = 181)成年女性完成了测量。横断面调节中介模型表明,种族/族裔状况并未调节关系,并且在每个时间点,身体羞耻感显著中介了身体监测与饮食失调病理之间的关系。使用交叉滞后面板分析的纵向模型不显著,因为在控制过去的身体羞耻感时,身体监测未能预测未来的身体羞耻感。
种族/族裔状况在任何时间点都未调节关系。横断面研究结果重复了过去的研究;纵向模型不支持通过身体羞耻感将自我客观化与饮食失调病理联系起来的核心中介途径。由于自我客观化被认为在生命早期就会出现,未来的研究还应在更年轻的多样化样本中,在更长的时间段内研究这些关系。
