Suicide ideation and related factors in old patients with depressive disorder

Abstract

Objective To explore the suicide ideation and related factors in elderly with depressive disorder. Methods A sample of 60 old patients meeting the criteria of ICD-10 for depressive disorder and 60 normal controls were assessed by the Self-rating Idea of Suicide Scale(SIOSS), Trait Coping Style Questionnaire(TCSQ), Self-Rating Anxiety Scale(SAS), Self-Rating Depression Scale(SDS) and Pittsburgh Sleep Quality Index(PSQI). Results The score of despair factor, optimistic factor, sleep factor, conceal factor and total score of SIOSS in patients with depressive disorders(6.22±3.28, 2.43±1.47, 1.87±1.58, 1.17±1.11 and 10.51±4.91, respectively) were significantly higher than those of normal controls(t=5.83-14.03, P<0.01). The scores of SIOSS in patients were significantly positively related with the scores of SAS, SDS, PSQI and NC(r=0.311-0.792, all P<0.05), but negatively related with the scores of PC(r=–0.761, P<0.01). Moreover, regression analysis showed that the suicide ideation was increased in accordance with serious depression, anxiety, sleep quality, higher level of education and decreased ability to positive response in elderly with depressive disorder(R2=0.853, F=62.768, P<0.01). Conclusion The suicide ideation in elderly with depressive disorder is more serious than that of normal people, and may be influenced by depression, anxiety, sleep quality and coping style.
