核电厂操纵人员抗应激能力与生理心理指标的相关性研究

目的 探讨核电厂操纵人员的抗应激能力及其与心率、血压和心理健康指标的相关性.方法 选取136名某核电厂男性操纵人员进行连续作业反应(CPT)及心理健康测试(MHT),37名某高校四年级男性学生作为对照,并记录测试前后血压、心率的变化.将操纵人员按CPT得分情况,分为高分组与低分组.分析比较受试者的抗应激能力及其与血压、心率和心理健康指标的关系.结果 核电厂操纵人员的CPT得分与MHT得分高于对照组(t=-1.25、6.25,P＜0.05);测试后,心率、收缩压、舒张压明显低于对照组(t =-2.07、3.28、2.74,P＜0.05).测试后高分组的心率、收缩压、舒张压低于低分组(t=-3.15、-2.78、-2.54,P＜0.05),CPT及MHT得分均优于低分组(t=0.63、6.90,P＜0.05).相关性分析表明,受试者的CPT得分与心率、收缩压、舒张压增幅成负相关(r=-0.69、-0.94、-0.62,P＜0.05),与MHT得分成正相关(r=0.54,P＜0.05).结论 CPT和MHT在一定程度上反映受试者的抗应激能力,可作为核电厂操纵人员的选拔与适任性评价的依据之一.

Correlation of anti-stress ability of nuclear power plant operators with physiological and psychological indexes

Objective To explore the correlation of the anti-stress ability of nuclear power plant operators with their heart rate, blood pressure and mental health. Methods A total of 136 male nuclear power plant operators received the continuous performance test (CPT) and mental health test (MHT), while 37 male senior students were used as the control group. Heart rate and blood pressure were recorded before and after the test. The nuclear power plant operators were divided to high score group and low score group by CPT scores. The correlation of the anti-stress ability and blood pressure, heart rate and their mental health was analyzedd. Results The scores of CPT and MHT test with the operators were significantly higher than those of the control group(t=-1.25, 6.25, P<0.05). After the test, the heart rate, systolic pressure and diastolic pressure of the operators were all significantly lower than those of the control group(t=-2.07, 3.28, 2.74, P<0.05). The CPT score of the high score group was lower in the heart rate, systolic pressure and diastolic pressure than the low score group(t= -3.15, -2.78, -2.54, P<0.05), while the scores of CPT and MHT were better(t=0.63, 6.90, P<0.05). CPT scores were negatively correlated with the increasing range of the heart rate, systolic pressure and diastolic pressure(r=-0.69, -0.94, and -0.62, P<0.05), and positively correlated with the MHT scores (r=0.54, P<0.05). Conclusions To a certain extent, CPT and MHT test can reflect the anti-stress ability and be used as one of the bases to select nuclear power plant operators and to assess their competence.
