Multicenter validation study.
The aim of this study was to translate and adapt the AOSpine PROST (Patient Reported Outcome Spine Trauma) into English, and test its psychometric properties among North-American spine trauma patients.
In the absence of an outcome instrument specifically designed and validated for traumatic spinal column injury patients, it is difficult to measure the effect size of various treatment options. The AOSpine Knowledge Forum Trauma initiated a project and developed the AOSpine PROST consisting of 19 items.
Patients were recruited from two level-1 North-American trauma centers. For concurrent validity, next to AOSpine PROST also 36-item Short-Form Health Survey (SF-36) was filled out by patients. Patient characteristics were analyzed using descriptive statistics. Floor and ceiling effects as well as the number of inapplicable and missing questions were analyzed for content validity. Cronbach α and item-total correlation coefficients (ITCCs) were calculated for internal consistency. Spearman correlation tests were performed within AOSpine PROST items and in correlation to SF-36. Test-retest reliability was assessed using intraclass correlation coefficients (ICCs). Factor analysis was performed to explore any dimensions within AOSpine PROST.
The AOSpine PROST was translated adapted into English using established guidelines. Of 196 enrolled patients, 162 (82.7%) met the inclusion criteria and provided sufficient data. Content validity showed good results, and no floor and ceiling effects were seen. The internal consistency was excellent (Cronbach α = 0.97; ITCC 0.50-0.90) as well as test-retest reliability (ICC = 0.97). Spearman correlations were good (0.29-0.85). The strongest correlations of AOSpine PROST with SF-36 were seen with the physical components (0.69-0.82; P < 0.001). Factor analysis revealed two possible dimensions (Eigen values >1), explaining 75.7% of variance.
The English version of AOSpine PROST showed very good validity and reliability. It is considered as a valuable tool, and has the potential to contribute to the reduction of ongoing controversies in spine trauma care.
多中心验证研究。
本研究旨在将 AOSpine PROST（脊柱创伤患者报告结局）翻译并改编为英文，并在北美脊柱创伤患者中测试其心理测量特性。
由于缺乏专门针对创伤性脊柱损伤患者设计和验证的结局工具，因此难以衡量各种治疗选择的效果大小。AOSpine 知识论坛创伤发起了一个项目，并开发了包含 19 个项目的 AOSpine PROST。
患者从两家北美 1 级创伤中心招募。为了进行同时效度评估，患者还填写了 36 项简明健康调查问卷（SF-36）。使用描述性统计分析患者特征。分析内容效度的地板效应和天花板效应以及不适用和缺失问题的数量。计算内部一致性的克朗巴赫 α 和项目总分相关系数（ITCC）。在 AOSpine PROST 项目内以及与 SF-36 进行 Spearman 相关性检验。使用组内相关系数（ICC）评估测试-重测信度。进行因子分析以探索 AOSpine PROST 内的任何维度。
AOSpine PROST 按照既定指南被翻译改编为英文。在纳入的 196 名患者中，162 名（82.7%）符合纳入标准并提供了足够的数据。内容效度良好，未见地板效应和天花板效应。内部一致性非常好（克朗巴赫 α=0.97；ITCC 0.50-0.90），测试-重测信度也很好（ICC=0.97）。Spearman 相关性良好（0.29-0.85）。AOSpine PROST 与 SF-36 的最强相关性见于生理成分（0.69-0.82；P<0.001）。因子分析显示有两个可能的维度（特征值>1），解释了 75.7%的方差。
AOSpine PROST 的英文版本具有非常好的有效性和可靠性。它被认为是一种有价值的工具，有可能有助于减少脊柱创伤护理中的持续争议。
