The primary goal of this study was to test a culturally specific model of binge eating in African American female trauma survivors, investigating potential mechanisms through which trauma exposure and distress were related to binge eating symptomatology.
Participants were 179 African American female trauma survivors who completed questionnaires about traumatic experiences; emotional inhibition/regulation difficulties; self-silencing (prioritizing others' needs and adopting external self-evaluation standards); eating for psychological reasons; binge eating; and internalization of "Strong Black Woman" (SBW) ideology, an important cultural symbol emphasizing strength and self-sufficiency.
Structural path analysis supported the proposed model in which SBW ideology, emotional inhibition/regulation difficulties, and eating for psychological reasons mediated the relationship between trauma exposure/distress and binge eating. The proposed model provided better fit to the data than several competing models.
These findings suggest that among African American trauma survivors, trauma exposure and distress predict greater internalization of SBW ideology, which is associated with emotional inhibition/regulation difficulties, eating for psychological reasons, and ultimately binge eating. Implications of these findings for assessment, treatment, and prevention efforts are discussed.
本研究的主要目的是检验一个针对非裔美国女性创伤幸存者的特定文化的暴食模型，通过考察创伤暴露和痛苦与暴食症状之间的潜在机制来进行研究。
参与者为 179 名非裔美国女性创伤幸存者，他们完成了关于创伤经历、情绪抑制/调节困难、自我沉默（优先考虑他人的需求并采用外部自我评估标准）、为心理原因而进食、暴食以及内化“坚强的黑人女性”（SBW）观念的问卷调查，SBW 观念是一个强调力量和自给自足的重要文化象征。
结构路径分析支持了所提出的模型，即 SBW 观念、情绪抑制/调节困难和为心理原因而进食在创伤暴露/痛苦与暴食之间起中介作用。与几个竞争模型相比，所提出的模型更符合数据。
这些发现表明，在非裔美国创伤幸存者中，创伤暴露和痛苦预测了对 SBW 观念的内化程度更高，这与情绪抑制/调节困难、为心理原因而进食有关，最终导致暴食。讨论了这些发现对评估、治疗和预防工作的影响。
