The aim of this study was to translate and culturally adapt the Short Musculoskeletal Function Assessment (SMFA) into Danish (SMFA-DK) and assess the psychometric properties.
SMFA was translated and cross-culturally adapted according to a standardized procedure. Minor changes in the wording in three items were made to adapt to Danish conditions. Acute patients (n = 201) and rehabilitation patients (n = 231) with musculoskeletal problems aged 18-87 years were included. The following analysis were made to evaluate psychometric quality of SMFA-DK: Reliability with Chronbach's alpha, content validity as coding according to the International Classification of Functioning, Disability and Health (ICF), floor/ceiling effects, construct validity as factor analysis, correlations between SMFA-DK and Short Form 36 and also known group method. Responsiveness and effect size were calculated.
Cronbach's alpha values were between 0.79 and 0.94. SMFA-DK captured all components of the ICF, and there were no floor/ceiling effects. Factor analysis demonstrated four subscales. SMFA-DK correlated good with the SF-36 subscales for the rehabilitation patients and lower for the newly injured patients. Effect sizes were excellent and better for SMFA-DK than for SF-36.
The study indicates that SMFA-DK can be a valid and responsive measure of outcome in rehabilitation settings.
本研究旨在将短肌肉骨骼功能评估（SMFA）翻译并文化调适为丹麦语（SMFA-DK），并评估其心理测量特性。
SMFA 按照标准化程序进行翻译和跨文化调适。对三个项目中的措辞进行了细微调整，以适应丹麦的情况。纳入了年龄在 18-87 岁之间有肌肉骨骼问题的急性患者（n=201）和康复患者（n=231）。为评估 SMFA-DK 的心理测量质量进行了以下分析：可靠性采用 Cronbach's alpha 值，内容有效性根据国际功能、残疾和健康分类（ICF）进行编码，地板/天花板效应，结构有效性采用因子分析，SMFA-DK 与 36 项简短表格（SF-36）之间的相关性，以及已知组方法。还计算了反应性和效应量。
Cronbach's alpha 值在 0.79 到 0.94 之间。SMFA-DK 捕捉到了 ICF 的所有组成部分，且无地板/天花板效应。因子分析显示出四个分量表。SMFA-DK 与康复患者的 SF-36 分量表相关性良好，而与新受伤患者的相关性较低。对于 SMFA-DK 和 SF-36，效应量均为极好，且对于 SMFA-DK 更好。
该研究表明，SMFA-DK 可作为康复环境中结果的有效且敏感的衡量标准。
