背景资料：脊柱功能指数（SFI）是最近发表的，强大的和clinimetrically有效的患者报告的outcome measure.Objectives：本研究的目的是适应和验证的西班牙语版本（SFI-SP）与文化和语言equivalents.Methods：一个两阶段的观察性研究进行。SFI是跨文化适应西班牙语，通过双重向前和向后翻译，然后验证其心理特征。不同脊柱疾病持续时间> 12周的参与者（n = 226）完成了SFI-Sp和区域特定测量：背部，罗兰莫里斯问卷（RMQ）和背痛指数（BADIX）;颈部，颈部残疾指数（NDI）;一般健康状况，EQ-5D和SF-12。本研究采用全样本法，以探讨量表的内部一致性、地区与健康的同步效标效度、构念效度与因子结构。结果：SFI-Sp具有较高的内部一致性（a = 0.85）和信度（r = 0.96）。因素结构为一维，支持结构效度。功能的标准特异性效度RMQ高（r = 0.79），BADIX中等（r = 0.59），NDI低（r = 0.46）。对于一般健康状况，EQ-5D较低，与SF-12的身体和精神组成部分呈负相关（r = -0.42），一般健康状况较好，与SF-12的身体和精神组成部分呈负相关（r = -0.56和r = -0.48）。该研究的局限性包括缺乏纵向数据的其他心理测量特性，特别是responsibility.Conclusions：SFI-SP被证明是一个有效的和可靠的脊柱区域的结果测量。的心理测量特性相媲美，并支持那些英文版，但需要进一步的纵向调查。
Background: The Spine Functional Index (SFI) is a recently published, robust and clinimetrically valid patient reported outcome measure.Objectives: The purpose of this study was the adaptation and validation of a Spanish-version (SFI-Sp) with cultural and linguistic equivalence.Methods: A two stage observational study was conducted. The SFI was cross-culturally adapted to Spanish through double forward and backward translation then validated for its psychometric characteristics. Participants (n = 226) with various spine conditions of > 12 weeks duration completed the SFI-Sp and a region specific measure: for the back, the Roland Morris Questionnaire (RMQ) and Backache Index (BADIX); for the neck, the Neck Disability Index (NDI); for general health the EQ-5D and SF-12. The full sample was employed to determine internal consistency, concurrent criterion validity by region and health, construct validity and factor structure. A subgroup (n = 51) was used to determine reliability at seven days.Results: The SFI-Sp demonstrated high internal consistency (a = 0.85) and reliability (r = 0.96). The factor structure was one-dimensional and supported construct validity. Criterion specific validity for function was high with the RMQ (r = 0.79), moderate with the BADIX (r = 0.59) and low with the NDI (r = 0.46). For general health it was low with the EQ-5D and inversely correlated (r = -0.42) and fair with the Physical and Mental Components of the SF-12 and inversely correlated (r = -0.56 and r = -0.48), respectively. The study limitations included the lack of longitudinal data regarding other psychometric properties, specifically responsiveness.Conclusions: The SFI-Sp was demonstrated as a valid and reliable spine-regional outcome measure. The psychometric properties were comparable to and supported those of the English-version, however further longitudinal investigations are required.
