Fatigue is a frequent and common symptom of multiple sclerosis (MS) that can interfere with patients' everyday activities. There is no objective scale for assessing fatigue in French MS patients. The objective of this study was to adapt an English language scale for use with French patients.
The Fatigue Impact Scale was translated and culturally adapted into French by a committee of medical and linguistic specialists. The psychometric properties of this new instrument, called EMIF-SEP were assessed.
EMIF-SEP is composed of 40 items. Four dimensions of this scale (cognitive, physical, social role and psychological) were identified by factor analysis. Each dimension had a high internal consistency (Cronbach's alpha >0.80). The test-retest reproducibility was very satisfactory; intra-class correlation coefficients were all above 0.70.
EMIF-SEP is the first scale for assessing MS-related fatigue which has been adapted to French-speaking patients. It is useful for clinical practice and MS-related research.
疲劳是多发性硬化症（MS）常见且频发的症状，会干扰患者的日常活动。目前尚无用于评估法国MS患者疲劳程度的客观量表。本研究的目的是对一份英文量表进行改编，以便用于法国患者。
医学和语言专家委员会将疲劳影响量表翻译并进行文化调适，使其适用于法语环境。对这个名为EMIF-SEP的新工具的心理测量特性进行了评估。
EMIF-SEP由40个项目组成。通过因子分析确定了该量表的四个维度（认知、身体、社会角色和心理）。每个维度都具有较高的内部一致性（克朗巴哈系数>0.80）。重测信度非常令人满意；组内相关系数均高于0.70。
EMIF-SEP是首个经过改编适用于法语患者的评估MS相关疲劳的量表。它对临床实践和MS相关研究很有用。
