Analysis of related factors to suicide attempt among patients with major depressive disorder in general hospital psychology clinic / 中国医师杂志

ABSTRACT

Objective To explore the prevalence and related factors of suicide attempt among patients with major depressive disorder (MDD) and to provide a scientific theoretical basis for preventing suicide attempts in patients with MDD.Methods The researchers selected 162 patients with MDD based on the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-Ⅳ) diagnostic criteria from some patients presenting in the department of Psychology at the First Affiliated Hospital of China Medical University during the January 2017 to March 2018,using the Structured Clinical Interview for DSM-Ⅳ-TR Patient version (SCID-P) as a screening tool.The self-designed General Information Questionnaire and Hamilton Depression Scale-17 items (HAMD-17) were used to investigate and evaluate the factors that affected suicide attempt.Results The detection rate of suicide attempt was 17.3％ (28/162).Compared with the two groups with or without a history of suicide attempt,the age of the MDD patients (Z =-2.183,P =0.029),the place of residence of the MDD patients (x2 =5.405,P =0.020),and the total score of the HAMD-17 scale (t =-2.132,P =0.035),the score of the depression factor (Z =-3.627,P ＜ 0.001),guilt factor score (Z =-3.086,P =0.002),the score of the suicidal ideation factor (Z =-5.088,P ＜0.001) and sleepiness score (Z =-2.021,P =0.043) were significantly different.Multivariate logistic regression analysis showed that age (OR =0.930,P =0.022) was a protective factor of suicide attempt and the residence in rural areas (OR =3.955,P =0.038),severe depression (OR =3.795,P =0.020) and suicidal ideation (OR =2.496,P =0.002) were independent risk factors for attempted suicide.Conclusions Residence in rural areas,younger age,suicidal ideation and depression are independent risk factors for suicide attempt of depressive patients.Clinical psychologists in general hospitals should strengthen the evaluation of these factors when inquiring to prevent the occurrence of suicide attempt.
