Although the link between body dissatisfaction and eating disorder (ED) pathology is well-established in general female samples, less is known about contextual body image (CBI) among female athletes. CBI refers to female athletes' body image concerns in two contexts: sport and daily life. The Contextual Body Image Questionnaire for Athletes (CBIQA) measures four dimensions of body image (Appearance, Thin-Fat Self-Evaluation, Thin-Fat Others' Evaluation, and Muscularity) in both contexts. In a sample of female collegiate athletes, this study sought to A) investigate the psychometric properties of the CBIQA, B) examine the cross-sectional relation of CBI with ED pathology and negative affect, and C) assess the degree to which CBI prospectively predicts ED pathology and negative affect.
Using self-report data collected from a multi-site parent trial, we examined the psychometric properties of the CBIQA by confirmatory factor analysis. We assessed construct and criterion validity via cross-sectional bivariate correlation analyses with thin-ideal internalization, negative affect, and ED pathology. Using data from Time 1 and 6 months later (Time 2), we investigated the degree to which CBI prospectively predicted ED pathology and negative affect.
Results from the CFA largely confirmed de Bruin et al.'s (2011) original factor analysis. Two CBIQA dimensions (Thin-Fat Self and Appearance) in both contexts correlated with ED pathology and negative affect. Thin-Fat Others also correlated with ED pathology in both contexts and negative affect in the sport context. The Muscularity dimension was predominantly orthogonal with other measures. CBIQA dimensions were uncorrelated with thin-ideal internalization. When controlling for BMI and Time 1 scores, daily life and sport appearance concerns predicted ED pathology, whereas perceived evaluation of thin-fat by others in the sport context predicted negative affect 6 months later.
Results support the psychometric validity of the CBIQA and suggest that it captures variance discrete from thin-ideal internalization. The Muscularity dimension largely was not related to other outcomes. Further, specific elements of perceived self- and other-evaluation in both contexts is relevant to risk for ED pathology and negative affect. Future research could examine the impact of dual body image between sports seasons and after transitioning out of sport.

尽管身体不满与饮食失调（ED）病理之间的联系在一般女性样本中已得到充分证实，但对于女运动员的情境身体意象（CBI）了解较少。CBI指女运动员在两种情境下的身体意象问题：运动和日常生活。运动员情境身体意象问卷（CBIQA）在这两种情境下测量身体意象的四个维度（外貌、瘦胖自我评估、瘦胖他人评估和肌肉量）。在一组女大学生运动员样本中，本研究旨在：A）调查CBIQA的心理测量特性；B）检验CBI与ED病理及消极情绪的横断面关系；C）评估CBI对ED病理和消极情绪的前瞻性预测程度。
使用从一项多中心母试验收集的自我报告数据，我们通过验证性因素分析来检验CBIQA的心理测量特性。我们通过与瘦理想内化、消极情绪和ED病理的横断面双变量相关分析来评估结构效度和效标效度。利用第1次和6个月后（第2次）的数据，我们调查了CBI对ED病理和消极情绪的前瞻性预测程度。
验证性因素分析的结果在很大程度上证实了德布鲁因等人（2011年）最初的因素分析。两种情境下的两个CBIQA维度（瘦胖自我和外貌）与ED病理及消极情绪相关。瘦胖他人在两种情境下也与ED病理相关，在运动情境下与消极情绪相关。肌肉量维度主要与其他测量指标呈正交关系。CBIQA维度与瘦理想内化不相关。在控制体重指数（BMI）和第1次得分后，日常生活和运动外貌担忧可预测ED病理，而在运动情境下他人对瘦胖的感知评价可预测6个月后的消极情绪。
结果支持CBIQA的心理测量效度，并表明它捕捉到了与瘦理想内化不同的变异。肌肉量维度在很大程度上与其他结果无关。此外，两种情境下感知到的自我和他人评价的特定要素与ED病理和消极情绪的风险相关。未来的研究可以考察运动季节之间以及退出运动后双重身体意象的影响。
