Abstract

OBJECTIVE

Despite the well-established health benefits of physical activity, the role of exercise for eating disorders (ED) is controversial; thus dictating a need for a better understanding of the mechanisms of exercise and ED. The purpose of our study was to examine a conceptual model that hypothesizes regular exercise without psychological compulsion might impart beneficial effects for preventing and treating ED.

METHOD

University students (N = 539) completed self-report assessments of quality of life, exercise level, ED risk and exercise dependence symptoms. Structural equation modelling analysis was undertaken to examine the conceptual model's proposed relationships.

RESULTS

Mediation analysis and model comparison tests showed that the partially mediated model without the physical well-being latent construct fit the data best.

DISCUSSION

Our results provided initial support for the conceptual model by showing that the psychological benefits, but not the physical benefits, conveyed by exercise were associated with reduced ED risk.

摘要

目的

尽管身体活动对健康的益处已得到充分证实,但运动对于饮食失调(ED)的作用仍存在争议;因此,需要更好地了解运动和 ED 的机制。我们的研究目的是检验一个概念模型,该模型假设没有心理强迫的规律运动可能对预防和治疗 ED 有益。

方法

大学生(N=539)完成了生活质量、运动水平、ED 风险和运动依赖症状的自我报告评估。采用结构方程模型分析来检验概念模型提出的关系。

结果

中介分析和模型比较检验表明,没有身体幸福感潜在结构的部分中介模型最适合数据。

讨论

我们的结果通过显示运动带来的心理益处,而不是身体益处,与降低 ED 风险有关,为该概念模型提供了初步支持。
