Abstract

Purpose: The role of body image in adolescent binge eating is widely confirmed, albeit the various facets of this relationship are still mostly unexplored. Within the multidimensional body image framework, this study hypothesized the indirect effects of three body image coping strategies (positive rational acceptance, appearance fixing, avoidance) in the expected relationship between the perceived impact of body image on individuals' quality of life and binge eating symptoms.

Methods: Participants were 715 adolescents aged 15-21 years (49.1% girls) recruited in Italian schools. An anonymous self-report online survey was administered. A multiple mediation model was tested.

Results: A more positive perceived impact of body image on quality of life was a negative predictor of adolescents' binge eating, controlling for individual levels of body satisfaction. Three indirect effects were found in this relationship: on one hand, the positive body image impact reduced binge eating via increasing positive rational acceptance (M1), and via reducing avoidance (M2); on the contrary, the positive body image impact also enhanced binge eating via increasing appearance fixing (M3).

Conclusions: The body image impact on quality of life can be alternatively protective-when adaptive coping is solicited, and maladaptive strategies are reduced-or a risk factor, which may increase binge eating by soliciting appearance fixing.

Level iii: Evidence obtained from cohort or case-control analytic studies.

身体形象对生活质量和青少年暴食的影响:身体形象应对策略的间接作用。
目的:身体形象在青少年暴饮暴食中的作用已被广泛证实,尽管这种关系的各个方面仍未被探索。在多维身体形象框架下,本研究假设了三种身体形象应对策略(积极理性接受、外貌固定、回避)在身体形象对个体生活质量的感知影响与暴饮暴食症状之间的预期关系中的间接作用。方法:在意大利学校招募715名15-21岁的青少年(49.1%为女孩)。进行了一项匿名自我报告在线调查。测试了一个多中介模型。结果:在控制个体身体满意度的情况下,身体形象对生活质量的积极影响是青少年暴食的负向预测因子。在这种关系中发现了三种间接影响:一方面,积极的身体形象影响通过增加积极的理性接受(M1)和减少回避(M2)来减少暴食;相反,积极的身体形象影响也会通过增加外表来增强暴饮暴食(M3)。结论:身体形象对生活质量的影响可以是保护性的——当适应性应对被诱导时,不适应策略被减少——或者是一个风险因素,它可能通过诱导外表修复而增加暴饮暴食。iii级:证据来自队列或病例对照分析研究。
