A study was undertaken to test the psychometric properties of the Fatigue Severity Scale (FSS), and to explore the relationship between fatigue and sociodemographic variables in the general population.
A national representative sample of 1893 respondents was randomly selected from a pool of 4,000 Norwegians aged 19-81 years. A mailed questionnaire that included the FSS was used to measure fatigue severity.
The FSS showed satisfactory internal consistency (Cronbach's alpha 0.88). The prevalence of high fatigue (FSS score > = 5) was 23.1% in the total sample. More women (26.2%) than men (19.8%) experienced high fatigue (p = 0.004). Respondents with chronic illness (more than six months) reported a higher mean (M = 4.69, SD = 1.35) than the rest of the sample (M = 3.67, SD = 1.17) (p<0.001). An inverse correlation was found between fatigue and level of formal education (r = 0.20, p<0.001).
The psychometric properties of the Norwegian version of FSS were satisfactory. To avoid over-diagnosing people for high level of fatigue, the threshold for high fatigue probably should be 5 on the FSS scale instead of 4 as had been suggested originally, but further validation of the cut-off point is needed.
开展一项研究以测试疲劳严重程度量表（FSS）的心理测量特性，并探讨普通人群中疲劳与社会人口统计学变量之间的关系。
从4000名年龄在19 - 81岁的挪威人中随机抽取1893名作为全国代表性样本。使用包含FSS的邮寄问卷来测量疲劳严重程度。
FSS显示出令人满意的内部一致性（克朗巴哈系数α为0.88）。总样本中高疲劳（FSS评分≥5）的患病率为23.1%。经历高疲劳的女性（26.2%）多于男性（19.8%）（p = 0.004）。患有慢性病（超过六个月）的受访者报告的平均得分（M = 4.69，标准差 = 1.35）高于样本中的其他受访者（M = 3.67，标准差 = 1.17）（p<0.001）。发现疲劳与正规教育水平之间存在负相关（r = 0.20，p<0.001）。
挪威版FSS的心理测量特性令人满意。为避免对高疲劳水平人群的过度诊断，高疲劳的阈值可能应为FSS量表上的5分，而非最初建议的4分，但需要对该临界点进行进一步验证。
