This study investigated the role of self-presentation motivation across three groups with known differences in disordered eating behavior.
Female participants (N=131) were currently in-treatment for an eating disorder (n=39), deemed at-risk (n=46), or not-at-risk for an eating disorder (n=46). All participants completed general and physique-specific measures of self-presentation motivation.
Results revealed significant moderate differences between groups. Those not-at-risk reported lower levels of self-presentation motivation across all measures compared to those in the other groups. Those at-risk reported significantly lower scores across global measures of self-presentation motivation, but not physique-specific motives, than those in-treatment. A discriminant function analysis demonstrated that self-presentation motivation correctly classified 63.4% of cases.
Results suggest that self-presentation motives may be particularly salient for individuals at-risk or in-treatment for eating disordered behavior.
本研究调查了自我展示动机在三组饮食失调行为存在已知差异的人群中的作用。
女性参与者（N = 131）目前正在接受饮食失调治疗（n = 39）、被视为有风险（n = 46）或没有饮食失调风险（n = 46）。所有参与者都完成了自我展示动机的一般测量和特定于体型的测量。
结果显示组间存在显著的中度差异。与其他组相比，无风险组在所有测量中报告的自我展示动机水平较低。有风险组在自我展示动机的总体测量中报告的分数显著低于接受治疗组，但在特定于体型的动机方面并非如此。判别函数分析表明，自我展示动机正确分类了63.4%的案例。
结果表明，自我展示动机对于有饮食失调行为风险或正在接受治疗的个体可能特别突出。
