Although there is growing evidence of an association between disordered eating and sexual dysfunction, the mechanism underlying this association is still unclear. In the current study, we sought to examine the mediating role of sexual motivation between disordered eating and sexual dysfunction. We used a multi-path mediation model to examine the mediating role of sexual motivation between disordered eating and sexual functioning among a sample of 341 non-clinical women in a steady relationship. Analysis revealed two significant mediation paths associating disordered eating with sexual functioning: (1) a high level of disordered eating was significantly linked with higher motivation for partner approval via sex and sexuality which, in turn, was associated with lower sexual functioning and (2) a high level of disordered eating was significantly linked with lower enhancement sexual motivation which, in turn, was associated with lower sexual functioning. This study extends the existing knowledge by offering an explanation for the relation between disordered eating and sexual dysfunction via sexual motives. Findings from the current study suggest women with disordered eating utilized sex for self-affirmation, for coping with negative emotions, for partner approval, and to increase intimacy. Also, these women were not likely to engage in sex for enhancement reasons.

尽管越来越多的证据表明饮食失调与性功能障碍之间存在关联，但这种关联的机制仍不清楚。在当前的研究中，我们试图探讨性动机在饮食失调和性功能障碍之间的中介作用。我们使用多路径中介模型来检验性动机在饮食失调和性功能之间的中介作用，其中包括 341 名处于稳定关系中的非临床女性样本。分析揭示了饮食失调与性功能之间的两条重要中介路径：（1）高水平的饮食失调与通过性和性行为获得伴侣认可的更高动机显着相关，这反过来又 与较低的性功能有关，并且（2）高水平的饮食失调与较低的增强性动机显着相关，而较低的性动机又与较低的性功能相关。这项研究通过性动机解释饮食失调和性功能障碍之间的关系，从而扩展了现有知识。目前的研究结果表明，饮食失调的女性利用性来自我肯定、应对负面情绪、获得伴侣的认可以及增加亲密感。此外，这些女性不太可能出于增强原因而发生性行为。这项研究通过性动机解释饮食失调和性功能障碍之间的关系，从而扩展了现有知识。目前的研究结果表明，饮食失调的女性利用性来自我肯定、应对负面情绪、获得伴侣的认可以及增加亲密感。此外，这些女性不太可能出于增强原因而发生性行为。这项研究通过性动机解释饮食失调和性功能障碍之间的关系，从而扩展了现有知识。目前的研究结果表明，饮食失调的女性利用性来自我肯定、应对负面情绪、获得伴侣的认可以及增加亲密感。此外，这些女性不太可能出于增强原因而发生性行为。
