目的了解24h睡眠剥夺对主观疲劳程度和心理运动能力的影响，探讨自拟的疲劳评价问卷评估主观疲劳程度的可行性。方法对医科大学12名男学员进行24h睡眠剥夺，以微机化神经行为进行视简单反应时和光标追踪测试，以自认疲劳分级（RPE）和自拟的疲劳调查问卷进行主观疲劳程度自评。结果受试者睡眠剥夺后视简单反应时显著延长，光标追踪偏差有所增加，疲劳评价问卷的总评分和各因子分非常显著地高于剥夺前;睡眠剥夺前后疲劳评价问卷总分与RPE评分的相关系数为r＝0.76（P＜0.01）。结论24h睡眠剥夺能引起心理运动能力的下降;疲劳评价问卷的信度和效度得到了初步验证，具有应用前景。
Objective To understand the effect of 24-h sleep deprivation on subjective fatigue and psychomotor capacity, and to explore the feasibility of evaluating the subjective fatigue degree by using the self-made fatigue assessment questionnaire. Methods 12 male students in the medical university underwent 24-h sleep deprivation, visual acuity simple tracking and cursor tracing were tested by computerized neurological behavior. The self-assessment of subjective fatigue degree was made by self-identified fatigue classification (RPE) and self-made fatigue questionnaire. Results After sleep deprivation, the simple visual response time was significantly prolonged and the cursor tracking deviation was increased. The total score and factor scores of the fatigue assessment questionnaire were significantly higher than those before deprivation; the scores of fatigue assessment before and after sleep deprivation were significantly higher than those of RPE The correlation coefficient was r = 0.76 (P <0.01). Conclusions 24h sleep deprivation can cause the decline of mental motor ability. The reliability and validity of the fatigue assessment questionnaire have been preliminarily verified and have potential applications.
