Abstract

Purpose: To evaluate compulsive exercise, researchers often rely on the widely used Compulsive Exercise Test (CET). However, the measure has shown unstable factor structure in several validation studies and is not available in Portuguese for use in Brazil. We aimed to describe the translation and cultural adaptation of the CET to Brazilian Portuguese, to test several factor structures among Brazilian and US samples of men and women, to test measurement invariance across countries, and to evaluate its internal consistency. Furthermore, we sought to evaluate convergent validity, correlating the CET with a measure of eating disorder symptoms, and to compare compulsive exercise symptoms between countries.

Methods: Four models of the latent structure of the CET were tested using confirmatory factor analyses (CFAs), three-factor structure with 15 items, three-factor structure with 18 items, four-factor structure with 21 items, and the original five-factor structure with 24 items, in a sample of 1,531 young adults (601 Brazilians and 930 Americans), aged 18-35 years.

Results: A series of CFAs demonstrated that the three-factor structure with 15 items showed a better fit to the data. This model demonstrated good convergent validity and internal consistency. Results from the CET multigroup CFA showed evidence for the invariance at the configural, metric, and scalar levels across Brazilians and Americans. Furthermore, significant differences were found between Brazilians and Americans, with Brazilians demonstrating higher scores on the Avoidance and rule-driven behavior and Mood improvement subscales, whereas US participants scored higher on the Weight control exercise subscale.

Conclusions: Results support the three-factor structure with 15 items to be used as a measure of compulsive exercise among Brazilians and Americans, allowing cross-cultural comparisons between these countries.

Level of evidence: Level V, Cross-sectional, Psychometric study.

巴西和美国年轻人强迫性运动测试的验证和测量不变性。
目的:为了评估强迫性运动,研究人员通常采用广泛使用的强迫性运动测试(CET)。然而,该测验在多项验证研究中显示出不稳定的因子结构,而且没有葡萄牙语版本供巴西使用。我们旨在介绍将 CET 翻译成巴西葡萄牙语并进行文化调整的情况,在巴西和美国的男性和女性样本中测试多个因子结构,测试不同国家间的测量不变性,并评估其内部一致性。此外,我们还试图通过将 CET 与饮食失调症状的测量方法相关联来评估收敛效度,并比较不同国家间的强迫性运动症状:方法:我们以 1531 名 18-35 岁的年轻人(601 名巴西人和 930 名美国人)为样本,使用确证因子分析(CFA)测试了 CET 潜在结构的四种模型:15 个项目的三因子结构、18 个项目的三因子结构、21 个项目的四因子结构以及 24 个项目的原始五因子结构:一系列的 CFAs 结果表明,包含 15 个项目的三因素结构更适合数据。该模型具有良好的收敛有效性和内部一致性。CET 多组 CFA 的结果表明,巴西人和美国人在构型、度量和标度层面上都具有不变性。此外,还发现巴西人和美国人之间存在明显差异,巴西人在回避和规则驱动行为以及情绪改善分量表上得分更高,而美国参与者在体重控制运动分量表上得分更高:结果支持将 15 个项目组成的三因素结构作为巴西人和美国人强迫性运动的测量指标,从而可以对这些国家进行跨文化比较:证据等级:V 级,横断面,心理测量学研究。

期刊介绍: Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity is a scientific journal whose main purpose is to create an international forum devoted to the several sectors of eating disorders and obesity and the significant relations between them. The journal publishes basic research, clinical and theoretical articles on eating disorders and weight-related problems: anorexia nervosa, bulimia nervosa, subthreshold eating disorders, obesity, atypical patterns of eating behaviour and body weight regulation in clinical and non-clinical populations.
