The patient-based evaluation of outcome is gaining increased importance. The aim of the study was to translate and culturally adapt the short musculoskeletal function assessment questionnaire (SMFA) into German and to evaluate the practicability, metric properties, and distribution characteristics of the German version (SMFA-D).
The SMFA is a questionnaire on the functional status of the musculoskeletal system of patients consisting of a function index (34 items) and bother index (12 items) with a 5-point response format. The SMFA was independently translated by orthopaedic-trained, qualified German- and English-speaking translators. A consensus committee review and selection of an optimally comprehensible German version was performed. Patients checked this version for comprehensibility and time to complete the questionnaire. 40 fluently German-speaking patients with primary osteoarthritis of the knee completed the SMFA-D twice at a one week interval. The test-retest reliability and internal consistency were evaluated. The values are standardized on an scale from 0-100. High values indicate a poor function.
The SMFA-D is comprehensible and can be completed within 20 minutes in the mean. There were no skewness and no floor or ceiling effects. The mean function index was 47 (SD 17, range 16-80). The mean bother index was 44 (SD 19, range 5-75). Test-retest reliability were 0.88 (function index) and 0.71 (bother index), respectively. Internal consistency (Cronbach's alpha) was 0.92 (function index) and 0.88 (bother index), respectively.
The SMFA-D is a practical and reliable questionnaire for patient-based evaluation of functional problems of the musculoskeletal system.
基于患者的结局评估正变得越来越重要。本研究的目的是将简短肌肉骨骼功能评估问卷（SMFA）翻译成德语并进行文化调适，以评估德语版（SMFA-D）的实用性、计量特性和分布特征。
SMFA是一份关于患者肌肉骨骼系统功能状态的问卷，由功能指数（34项）和困扰指数（12项）组成，采用5点应答格式。SMFA由经过骨科培训、具备德语和英语能力的合格翻译人员独立翻译。进行了一次共识委员会审查，并选择了一个最佳理解的德语版本。患者检查该版本的可理解性以及完成问卷所需的时间。40名德语流利的膝关节原发性骨关节炎患者每隔一周完成两次SMFA-D。评估了重测信度和内部一致性。这些值在0至100的量表上进行标准化。高值表示功能较差。
SMFA-D易于理解，平均可在20分钟内完成。不存在偏态，也没有地板效应或天花板效应。功能指数的平均值为47（标准差17，范围16 - 80）。困扰指数的平均值为44（标准差19，范围5 - 75）。重测信度分别为0.88（功能指数）和0.71（困扰指数）。内部一致性（Cronbach's α）分别为0.92（功能指数）和0.88（困扰指数）。
SMFA-D是一种实用且可靠的问卷，用于基于患者的肌肉骨骼系统功能问题评估。
