青年士兵疲劳状况及与自杀意念的相关性研究

Correlation analysis of fatigue and suicidal ideation among young soldiers

目的探讨青年士兵疲劳状况及与自杀意念的相关性。方法运用疲劳评定量表(FAI)和军人自杀意念量表(MSIS)对青年士兵进行测评。结果共调查974人,存在不同程度疲劳313人(占32.14%),疲劳对特异性环境比较敏感606人(占62.23%);疲劳评定4个因子中(因子1,GFSS,疲劳严重程度量表;因子2,SFS,情景特异性疲劳量表;因子3,FCS,疲劳后果量表;因子4,RR/S,疲劳对休息、睡眠反应量表),除了缓解疲劳的因子4外,其他疲劳因子和疲劳总分与自杀意念各因子和总分均呈正相关(P值均<0.01)。疲劳4个因子对自杀意念的预测力为41.8%。以FCS的预测力最佳,其解释量为33.7%,其余依次为GFSS、SFS和FCS,其解释量分别为7.3%、0.4%和0.4%。标准化回归方程为:自杀意念=0.412FCS+0.276GFSS+0.100SFS-0.069RR/S。结论青年士兵疲劳状况不容乐观,应引起重视,且疲劳对自杀意念有较强的预测力,对青年士兵的疲劳要及时预警和干预,防止恶性事件发生。

Objective to study correlation of fatigue status and suicidal ideation among young soldiers. Methods Young soldiers were investigated with FAI and MSIS. Results Among 974 subjects investigated, 313 were suffered with certain level of fatigue （accounted for 32.14%）, 606 cases were sensitive to specific environment（SFS） （accounted for 62.23%）. There are 4 factors in fatigue assessment：factor 1 was GFSS （fatigue severity scale）, factor 2 was SFS （situational specific fatigue scale）, factor 3 was FCS（ fatigue consequences scale）, factor 4 was RR/S（ fatigue to rest, sleep response scale）.Except for factor 4, all other factors and total score of fatigue were positively correlated with the factors and total score of suicidal ideation （all P 〈0.01）.The predictive capability of 4 factors for suicidal ideation was 41.8%. For a single factor, FCS had the best predication variance of suicidal ideation of 33.7%, followed by GFSS,SFS and FCS, whose prediction variances were 7.3%,0.4% and 0.4%, respectively. The standardized regression equation was： suicidal ideation =0.412× FCS＋0.276×GFSS＋0.100×SFS-0.069×RR/S. Conclusion The fatigue status of young soldiers were serious, which required more attention. The fatigue status had strong predictive capability for suicidal ideation. Therefore, the fatigue status of young soldiers should be timely warned and intervened in order to manage suicide effectively and prevent malignant events.
