| Objective To investigate the effect of social support on suicidal ideation in patients with major depression disorder (MDD)，and to provide references for reducing suicidal ideation and suicidal behavior of MDD patients.Methods A total of 1 135 MDD outpatients in Wuhan Mental Health Center who met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) were included by two-stage sampling method. All the selected patients were assessed by Patient Health Questionnaire (PHQ-9) and Social Support Rating Scale (SSRS), and the influencing factors of suicidal ideation in MDD patients were explored by binary Logistic regression analysis.Results Among 1 135 MDD patients, 688 (60.62%) had suicidal ideation. PHQ-9 score of patients with suicidal ideation was significantly higher than those without suicidal ideation [(14.18±5.02) vs. (11.07±4.61), t=10.497, P<0.01]. The scores of subjective support, the degree of support utilization and the total score of SSRS in those with suicidal ideation were all lower than those without suicidal ideation, with significant difference (P<0.01). Taking suicide ideation as dependent variable, and objective support, subjective support, utilization of support and PHQ-9 score as independent variables, binary Logistic regression equations was as follow: logit (P)=-0.286+0.026X1-0.035X2-0.063X3+0.128X4, indicating that both subjective support and depression had predictive values for suicidal ideation (B=-0.035, 0.128, P<0.05 or 0.01).Conclusion Depression and lack of social support, especially subjective support, may be risk factors for suicidal ideation in MDD patients. |
