ABSTRACT
Objective:To explore the prevalence rate of suicidal ideation and its risk and protective factors in military personnel.Methods:A total of 2071 military personnel were investigated by stratified random cluster sampling in May to August of 2015.The Question 7 of Beck Depression Scale (BDI) was used to test suicide ideation (item 7 score ≥ 1 was dovetailed in suicide ideation group).Family,social demographic and occupational factors were assessed with the self-made general characteristics questionnaire.The data were analyzed with multiple stepwise logistic regression.Results:There were 382 (18.4％) military personnel whose scores of item 7 were ≥1.Family history of suicide (OR =42.97,95％ CI =29.14-63.35),surrounding suicide (OR =2.46,95％ CI =1.75-3.46),drinking (OR =1.64,95％ CI =1.31-2.07) and level of education (OR =1.38,95％ CI =1.01-1.90) were risk factors of suicidal ideation.Protective factors were (OR =0.60,95％ CI =0.50-0.72) and station (OR =0.15,95％ CI =0.03-0.64).Conclusion:It suggests that in suicidal prevention for military,more attention is deserved paying to those military personnel who have family history of suicide,surrounding suicide,drinking habit,and are stationed in remote areas and air force.
ABSTRACT
Objective To explore the relationship among personality traits,aggression,depression,anxiety and suicide ideation by developing a structural equation model.MethodsA total of 2141 participants derived from a stratified random cluster sampling were investigated with Eysenck personality questionnaire(EPQ),aggression questionnaire(AQ),patient health questionnaire depression scale(PHQ-9) ,generalized anxiety disorder scale(GAD-7) and Beck depression inventory(BDI-13).ResultsIn EPQ,the scores of neuroticism,extroversion and psychoticism were (40.00±5.84),(59.84±7.02)and (36.63±6.41) respectively.In AQ,the scores of physical aggression,verbal aggression and anger were (32.41±5.15),(30.43±7.24),and (34.39±6.09) respectively.The median scores of PHQ-9 and GAD-7 were 5 and 6,and the inter-quartile range were 4 and 5.The suicide ideation was correlated with measurement indicator respectively(r=-0.19-0.40,P<0.01).Aggression and depression directly affected suicide ideation(direct effect was 0.27,0.24 respectively) and aggression indirectly affected suicide ideation trough anxiety(indirect effect was 0.02).Personality traits indirectly affected suicide ideation through aggression,anxiety and depression(indirect effect was 0.40).Anxiety indirectly affected suicide ideation through depression(indirect effect was 0.13).ConclusionPersonality traits,aggression,anxiety and depression affect suicide ideation,and these factors have different effecting mechanism.
