目的:探讨维和官兵心理健康变化特点及心理行为干预效果。方法:将84名赴苏丹维和官兵随机分为研究组和对照组各42名,维和前对研究组进行为期2个月的心理行为干预,维和期间进行太极拳训练。采用中国军人心理健康评估系统(CMMHS)分别于维和前、后进行心理健康评估;同时进行事件相关电位P300、总三碘甲状腺原氨酸(TT3)、总甲状腺激素(TT4)和皮质醇(COR)水平测定。结果:研究组维和后CMMHS总分及强迫、焦虑、抑郁、恐怖和神经衰弱因子分均明显低于对照组(P<0.05或P<0.01);而对照组CMMHS总分及强迫、焦虑、抑郁、恐怖和神经衰弱因子分均明显高于维和前(P<0.05或P<0.01)。研究组维和后P2、N2和P3潜伏期均明显短于对照组,P2、N2和P3波幅均明显高于对照组(P均<0.05)。研究组维和后血清TT3水平(1.75±0.30)nmol/L和TT4水平(98.56±18.49)nmol/L明显低于对照组(1.99±0.33)nmol/L和(106.15±20.22)nmol/L(P均<0.05);对照组TT3水平高于维和前(P<0.05),两组COR水平均明显高于维和前(P均<0.01)。结论:维和行动对官兵的心身健康和认知功能影响明显,心理行为干预可以有效提高官兵的心身健康水平。
Objective: To explore the characteristics of mental health of peacekeeping officers and soldiers and the effect of psychological intervention. Methods: Eighty-four officers and soldiers of peacekeeping peacekeeping mission in Sudan were randomly divided into two groups: study group and control group, each with 42 persons. Two months psychological intervention before study group and Taijiquan group during peacekeeping period. Mental health assessment was carried out before and after peacetime with CMMHS. Event-related potentials (P300), total triiodothyronine (TT3), total thyroid hormone (TT4) and cortisol ) Determination of the level. Results: The total scores of CMMHS and the scores of forcing, anxiety, depression, terror and neurasthenia in the study group were significantly lower than those in the control group (P <0.05 or P <0.01) , Horror and neurasthenia factor scores were significantly higher than before peacekeeping (P <0.05 or P <0.01). The latency of P2, N2 and P3 in the study group was significantly shorter than that in the control group, and the amplitude of P2, N2 and P3 were significantly higher than those in the control group (all P <0.05). The serum levels of TT3 (1.75 ± 0.30) nmol / L and TT4 (98.56 ± 18.49) nmol / L in the study group were significantly lower than those in the control group (1.99 ± 0.33 nmol / L and 106.15 ± 20.22 nmol / L (All P <0.05). The level of TT3 in the control group was significantly higher than that before peacekeeping (P <0.05). COR levels in both groups were significantly higher than those before maintenance (P <0.01). Conclusion: Peacekeeping operations have obvious impact on the mental and physical health and cognitive functions of officers and men. Mental and behavioral interventions can effectively improve the mental and physical health of officers and men.
