Studies Of Evaluation And Intervention Strategies On Mental Health Status Of Military NBC Defense Rescue Team In Shanghai World Expo Security

Objective: This study aimed to investigate the mental health status of theMNBCDMR(Military Nuclear,Biological and Chemical Defense Medicine Practitioners)who maintain security in Shanghai Expo. Explore the related causes, construct thepsychology multidimensional intervention model, and observed its effect. In order toprovide reference and evidence for establishing scientific effective mental health system.Methods: All the members in technology group and soldier group of the MNBCDMP（Military Nuclear,Biological and Chemical Defense Medicine Practitioners） of a troop,619in all, were chosen by cluster sampling,78of which were coming from the technology group,and541of which were coming from the soldier group. A research on general conditions wereconducted during the first month of the security operation in Shanghai Expo, and a clusterinvestigation on the psychological health background of the MNBCDMP members wereconducted during their security services in Shanghai Expo through internationally generalquestionnaires, including SCL-90（The self-report symptom inventory，Symptom Checklist90）, SAS（Self-Rating Anxiety Scale）, SDS（Self-rating depression scale） and SCSQ（Simplified Coping Style Questionnaire）.Accordingtotheresults,andbyusingthemethodsof documentary reference Jiang-Qianjin psychological stress model theory and crisis interventionmethods, we promoted targeted intervention measures, and conducted intervention research;meanwhile, we implemented integrated psychological intervention measures on the members oftechnology group and soldier group with focus on the multi-dimensional nature of intervention.We conducted the before-after study. We implemented no targeted intervention measures exceptroutine political education in the first month of the intervention; and implemented interventionmeasures in the later stage. We conducted tests on the psychological well-beings of intervieweesthrough the scales of SAS, SDS and SCSQ, compared the anxious and depressive states and thecoping modes of members in technology group and soldier group before and after intervention, toassess the effect of these intervention measures on the psychological well-beings of MNBCDMP. Results:①Technology group and soldiers group have great difference in demographydata.②T he SCL-90factor scores of619interviewees were all higher than military norms. Thefactor scores of soldier group members in terms of SCL-90and the positive rate were significantlylower than those of technology group members. But factor scores of soldier group members interms of SAS、SDS and the positive rates were higher than those of technology group members.③Negative coping dimension scores (SCSQ) of technology and soldiers group memberssignificantly better than the normal group, but there was no significantly different among the twogroup.④T he multiple regression analysis has shown that the psychological well-beings of soldiergroup members were related with their educational levels and the teams they were allocated in.There was no significantly difference between the coping modes of members in soldier group andtechnology group. The psychological well-beings of MNBCEMP were negatively correlated withpositive coping modes, and positively correlated with negative coping modes.⑤In the first monthwith no targeted intervention, the anxious and depressive states of the members of technologygroup and soldier group significantly increased After the intervention, the anxious and depressivestates were showing decreasing trend, with a statistically significant difference (P＜0.01); thepositive rate significantly decreased; the intervened level was lower than background level;⑥Thecoping modes also have undergone changes, the coping modes of members of technology groupwere relatively mature, resulting in no significant change, while the difference of soldier groupwas relatively bigger, resulting from more and more soldiers starting getting used to applypositive coping mode.Conclusion：The psychological well-beings of MNBCDMP were better than local andmilitary norms, demonstrating the sound psychological selection procedure. Under thesituation of constantly increased security pressure and heavier security preparation tasks, theintegrated psychological intervention model has been effective in reducing the anxious anddepressive states of MNBCDMP in different degrees, and in turning their coping modes intopositive, showing that the integrated psychological intervention model is an effectivepsychological intervention measure aiming at MNBCDMP.
