To conduct a cross-cultural adaptation and validation of the Core Outcome Measures Index (COMI) in the Slovenian language, for use in patients with low back pain.
The English version of COMI was translated into Slovene following established guidelines. Three hundred fifty-three patients with chronic low back pain were recruited from the Orthopedic clinic department of a tertiary care teaching institution. Data quality, construct validity, responsiveness, and test-retest reliability of the COMI were assessed.
The questionnaire was generally well accepted with no missing values. The majority of items exhibited only mild ceiling effects (below 20.0%) and somewhat more prominent floor effects, which were similar to previous studies (4.5-78.8%). Correlations with Oswestry Disability Index (ODI) were high (ρ = 0.76 between overall COMI and ODI scores), suggesting that the Slovene version of COMI had high construct validity. Additionally, the Slovene version of COMI successfully captured surgical patients' improvement in their low back problem after surgery (overall COMI score change: Z = - 9.34, p < .001, r = - 0.53) and showed acceptable test-retest reliability (ICC = 0.86).
The Slovene version of COMI showed good psychometric properties, comparable to those of previously tested language versions. It represents a valuable instrument for the use in future domestic and multicenter clinical studies.
为了在斯洛文尼亚语中进行跨文化适应性和验证核心结局测量指标（COMI），并将其用于腰痛患者。
按照既定的指南，将 COMI 的英文版本翻译成斯洛文尼亚语。从一家三级护理教学机构的骨科诊所部门招募了 353 名慢性腰痛患者。评估了 COMI 的数据质量、结构有效性、反应性和重测信度。
该问卷通常被广泛接受，没有缺失值。大多数项目仅表现出轻微的天花板效应（低于 20.0%）和更为明显的地板效应，与之前的研究相似（4.5-78.8%）。与 Oswestry 残疾指数（ODI）的相关性很高（COMI 总分与 ODI 得分之间的ρ=0.76），表明斯洛文尼亚语版 COMI 具有较高的结构有效性。此外，斯洛文尼亚语版 COMI 成功捕捉到手术后手术患者腰痛问题的改善（COMI 总分变化：Z=-9.34，p<.001，r=-0.53），并表现出可接受的重测信度（ICC=0.86）。
斯洛文尼亚语版 COMI 表现出良好的心理测量特性，与之前测试的语言版本相当。它是未来国内和多中心临床研究的有价值的工具。
