A growing number of research papers regarding Spanish-speaking dancers justifies the need for an adapted Spanish version of the Dance Functional Outcome Survey (DFOS). The objective of this study was to cross-culturally adapt and validate the DFOS for Spanish-speaking dancers. A sample of 127 healthy and injured professional and pre-professional dancers were recruited. Test-retest reliability of DFOS-Sp was examined using intraclass correlation coefficients. Construct validity compared DFOS-Sp to the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) using Pearson correlations. Principal component analysis identified factors and internal-item consistency. Sensitivity was evaluated by generating receiver operating characteristic and area under the curve analyses. A subgroup of 51 injured dancers were followed across three time-points to examine responsiveness using repeated measures analysis of variance. Injured scores were analyzed for floor and ceiling effects. The DFOS-Sp showed high test-retest reliability (ICC2,1 ≥ 0.92). DFOS-Sp scores had moderate construct validity compared with SF-36 physical component summary scores (r ≥ 0.56). Principal component analysis (PCA) supported uni-dimensionality explaining 58% of the variance with high internal consistency (α = 0.91).Area under the curve (AUC) sensitivity values were excellent (AUC ≥ 0.82). There were significant differences across time ( < 0.001), demonstrating responsiveness to change, with no floor or ceiling effects. The DFOS-Sp demonstrated acceptable test-retest reliability and validity in Spanish-speaking dancers, with comparable psychometric performance to the English-language version.
越来越多关于讲西班牙语舞者的研究论文表明，需要一个经过改编的西班牙语版舞蹈功能结果调查问卷（DFOS）。本研究的目的是对DFOS进行跨文化改编并验证其在讲西班牙语舞者中的有效性。招募了127名健康和受伤的专业及准专业舞者作为样本。使用组内相关系数检验DFOS-Sp的重测信度。通过Pearson相关性分析将DFOS-Sp与医学结果研究36项简短健康调查问卷（SF-36）进行比较，以检验结构效度。主成分分析确定因素和内部项目一致性。通过生成受试者工作特征曲线和曲线下面积分析来评估敏感性。对51名受伤舞者的亚组在三个时间点进行随访，使用重复测量方差分析来检验反应度。分析受伤得分的地板效应和天花板效应。DFOS-Sp显示出较高的重测信度（ICC2,1≥0.92）。与SF-36身体成分总结得分相比，DFOS-Sp得分具有中等结构效度（r≥0.56）。主成分分析（PCA）支持单维度性，解释了58%的方差，内部一致性高（α=0.91）。曲线下面积（AUC）敏感性值极佳（AUC≥0.82）。各时间点存在显著差异（<0.001），表明对变化有反应度，且无地板效应或天花板效应。DFOS-Sp在讲西班牙语的舞者中表现出可接受的重测信度和效度，其心理测量性能与英语版本相当。
