■由于没有经过科学验证的德语版本的运动行为调节问卷(BREQ-3),这项研究的目的是评估其在讲德语的年轻人样本中的心理测量参数和性别不变性。BREQ-3是衡量运动动机的社会和内部影响的工具。该工具在科学界广泛使用,并已以多种语言进行了验证。
■共有271名参与者(45%为女性;平均年龄=20.67±2.17岁;效应大小≥0.5)在一个时间点填充BREQ-3,15天后,一个小的子样本(n=37)第二次响应。验证性因子分析,结构建模,和组内相关系数用于检验德语版问卷。
■结果强调了移除两个项目后六维模型的良好拟合(CFI=0.912;SRMR=0.0594;RMSEA=0.064),以及跨性别的完全不变性(pχ2=0.218;ΔCFI<0.01)。内部一致性和可靠性中等到良好。
■22项德国BREQ-3是一种科学有效的工具,可用于处理运动行为的社会方面的跨国研究。
UNASSIGNED: Since there is no scientifically validated German version of the Behavioral Regulation in Exercise Questionnaire (BREQ-3), the aim of this study was to assess its psychometric parameters and invariance across sex in a sample of German-speaking young adults. The BREQ-3 is an instrument measuring the social and internal influences of motivation toward exercising. This tool is widespread within the scientific community and has been validated in several languages.
UNASSIGNED: A total of 271 participants (45% women; mean age = 20.67 ± 2.17 years; effect size ≥ 0.5) filled in the BREQ-3 at one time point, with a small sub-sample (n = 37) responding it a second time after 15 days. Confirmatory Factorial Analysis, Structural Modeling, and Intraclass Correlation Coefficient were used to examine the German version of the questionnaire.
UNASSIGNED: Results highlighted a good fit of the six-dimensional model after the removal of two items (CFI = 0.912; SRMR = 0.0594; RMSEA = 0.064), as well as full invariance across sex (pχ2 = 0.218; ΔCFI < 0.01). Internal consistency and reliability were moderate to good.
UNASSIGNED: The 22-item German BREQ-3 is a scientifically valid instrument that can be used in cross-national studies dealing with social aspects of exercise behaviors.
