The eating disorder literature has sought to understand the role of comorbid psychiatric diagnoses and coping in relation to eating disorders. The present research extends these findings by studying the relationships among depression, coping, and the entire continuum of disordered eating behaviors, with an emphasis on subthreshold eating disorders.
109 undergraduate females completed questionnaires to assess disordered eating symptoms, depressive symptoms, and the use of active and avoidant coping mechanisms. Hypotheses were tested using bivariate linear regression and multivariate linear regression.
Results indicated that depression was a significant predictor of disordered eating symptoms after controlling for relationships between depression and coping. Although avoidant coping was positively associated with disordered eating, it was not a significant predictor after controlling for depression and coping.
Previous research has found associations between depression and diagnosable eating disorders, and this research extends those findings to the entire continuum of disordered eating. Future research should continue to investigate the predictors and correlates of the disordered eating continuum using more diverse samples. Testing for mediation and moderation among these variables may also be a fruitful area of investigation.
饮食失调文献试图了解合并的精神科诊断和应对与饮食失调的关系。本研究通过研究抑郁、应对和整个饮食失调行为连续统之间的关系，以及对亚阈值饮食失调的关注，扩展了这些发现。
109 名本科女性完成了问卷，以评估饮食失调症状、抑郁症状和积极应对和回避应对机制的使用。使用双变量线性回归和多变量线性回归检验假设。
结果表明，在控制抑郁和应对之间的关系后，抑郁是饮食失调症状的一个重要预测因素。尽管回避应对与饮食失调呈正相关，但在控制抑郁和应对后，它不是一个显著的预测因素。
以前的研究发现抑郁与可诊断的饮食失调之间存在关联，本研究将这些发现扩展到整个饮食失调连续统。未来的研究应该继续使用更多样化的样本，调查饮食失调连续统的预测因素和相关性。在这些变量之间测试中介和调节也可能是一个富有成效的研究领域。
