Body dissatisfaction is an important correlate of dysfunctional eating. In the present study (N=208) the primary aim was to test whether women's internal and autonomous motivation can protect against endorsements of societal pressures regarding the ideal female body and against body dissatisfaction. Additionally, the role of others' autonomy support was investigated. Women who reported more Global Self-Determination (GSD) were lower in internalisation of the thin ideal and this association was fully mediated by perceived sociocultural pressure to be thin. Moreover, the positive association between perceived pressure and body dissatisfaction was partially mediated by thin ideal internalisation. Body dissatisfaction was associated with a more controlled regulation of eating, and GSD moderated the association between body dissatisfaction and autonomous regulation of eating. Autonomy support played a role in eating regulation as women with more support reported more autonomous eating. Yet, the support did not moderate the relationship between body dissatisfaction and eating regulation. Future studies should continue to explore the potential facilitative role of autonomy support in promoting a self-determined approach to eating regulation.
身体不满是功能失调性进食的一个重要相关因素。在本研究（N=208）中，主要目的是测试女性的内在和自主动机是否可以防止对理想女性身体的社会压力的认可和身体不满。此外，还研究了他人自主性支持的作用。报告全球自我决定（GSD）更高的女性对瘦理想的内化程度较低，这种关联完全由感知到的瘦的社会文化压力介导。此外，感知到的压力与身体不满之间的正相关部分由瘦理想内化介导。身体不满与饮食的更受控调节有关，而 GSD 调节了身体不满与自主调节饮食之间的关系。自主性支持在饮食调节中起着作用，因为支持更多的女性报告了更多的自主饮食。然而，支持并没有调节身体不满和饮食调节之间的关系。未来的研究应该继续探索自主性支持在促进自主饮食调节方法方面的潜在促进作用。
