一种疲劳自评问卷的信度和效度初探

The Pilot Study of a Fatigue Questionnaire

目的 :探讨以量表形式自我评价主观疲劳程度的可行性。方法 :建立一种简便、实用的主观疲劳程度自评问卷 ,对其信度和效度进行初步检验。结果 :该问卷总分和各因子分两次测试评分的相关系数分别为 0 .95、0 .80、0 .89、0 .6 0 (P <0 .0 1) ;总分和各因子分相互之间高度相关 ,且与自认疲劳分级 (RPE)、睡眠质量问卷、症状自评量表 (SCL - 90 )总分具有高度相关性。健康男性医学生 2 4h睡眠剥夺后疲劳问卷总分和各因子分比平时显著增高 (P <0 .0 1)。舰员经 2个多月海上航行后疲劳问卷总分和各因子分显著高于医学生平时 (P <0 .0 1) ,但低于医学生 2 4h睡眠剥夺后 (P <0 .0 1)。结论 :该问卷具有较高的信度和效度。对问卷内容进行修订 ,并作进一步标准化后 ,可望用于对健康人群主观疲劳程度的评价。

Objective: To investigate the practical value of a questionnaire in measuring the severity of subjective fatigue. Methods: A self rating scale with 3 factors covering 30 items was developed. Test retest reliability, internal consistency, correlation coefficients were tested in 75 male medical students and 29 ship personnel after a two month ocean voyage. Results: There were high degree test retest reliability and internal consistency. A significant(P<0.01) correlation was found of the scale with Ratings of Perceived Exertion (RPE, 0.29-0.47), Sleep Quality Scale(-0.37--0.54) and Symptom Checklist 90(SCL 90, Chinese revision, 0.64-0.83). The fatigue scores of the medical students after 24h sleep deprivation were significantly higher than in normal times (P<0.01). The fatigue scores of the ship personnel after a two month ocean voyage were significantly higher than the students' basal scores (P<0.01), but lower than those of the students after 24h sleep deprivation (P<0.01). Conclusion: The scale was found to be both reliable and valid. There is a reasonable prospect of measuring the severity of subjective fatigue with this scale. Further standardization is needed.
