This study evaluates the metric and scalar invariance of the Sport Anxiety Scale-2 (SAS-2), which is considered one of the best sport performance anxiety assessment tools for child and adolescent athletes, across four sampling variables: language, gender, age and type of sport.
The participants were 842 athletes (Mage = 11.73, SD = 2.20) from Spain, Belgium and Portugal, each of whom completed the language-adapted version of the SAS-2. Confirmatory factor analysis was used to test the invariance of the measurement model, and the relative importance of the sampling variables was assessed using a multiple indicator multiple causes model (MIMIC).
The results revealed metric and scalar invariance across all sampling variables and null to modest effects of gender, age and type of sport as covariates for the factors of the SAS-2. However, there was a marked effect (ß = -.56) of language on worry, which reflected lower scores on this factor for the Flemish sample.
The results of this study provide evidence of the invariance of the SAS-2 across samples, thereby endorsing the reliability of its factorial structure for future multi-group research.
本研究评估了运动焦虑量表-2（SAS-2）的测量不变性和标量不变性。SAS-2被认为是针对儿童和青少年运动员的最佳运动表现焦虑评估工具之一，本研究涉及四个抽样变量：语言、性别、年龄和运动类型。
参与者为来自西班牙、比利时和葡萄牙的842名运动员（年龄均值=11.73，标准差=2.20），他们每人都完成了SAS-2的语言适配版本。使用验证性因素分析来检验测量模型的不变性，并使用多指标多原因模型（MIMIC）评估抽样变量的相对重要性。
结果显示，在所有抽样变量上均存在测量不变性和标量不变性，并且性别、年龄和运动类型作为SAS-2各因素的协变量，其影响为零至中等程度。然而，语言对担忧有显著影响（β=-0.56），这反映出弗拉芒语样本在该因素上得分较低。
本研究结果提供了SAS-2在不同样本间具有不变性的证据，从而支持其因子结构在未来多组研究中的可靠性。
