The influence of cognition on suicidal ideation of major depressive patients / 中华行为医学与脑科学杂志

ABSTRACT

Objective@#To analyze the influence of cognition on suicidal ideation in patients with major depressive disorder.@*Methods@#A total of 108 inpatients with major depressive disorder from January 2017 to September 2018 in Beijing Huilongguan Hospital were enrolled.They were divided into suicidal ideation group (n=42) and non-suicidal ideation group (n=66) by the self-rating idea of suicide scale (SIOSS). Cognition was assessed by Repeatable Battery for the Assessment of Neuropsychological Status(RBANS). The general situation was assessed by self-made general situation questionnaire.The related factors were analyzed by Logistic regression.@*Results@#(1) The rate of suicidal ideation was 44.4% in patients with major depressive disorder.(2) The total score of RBANS and five-factor scores of RBANS in suicidal ideation group were lower than those in non-suicidal ideation group(total RBANS score(63.0±7.9) vs (73.8±7.7); immediate memory (62.7±8.8) vs (70.8±7.6); visual span (67.2±10.0) vs (72.7±9.8); speech function (83.3±13.8) vs (91.5±4.5); attention (85.3±11.9) vs (99.9±8.5); delayed memory (53.5±7.7) vs (62.3±9.7), F=6.335-46.660, P<0.05). (3)Logistic regression showed, years of education were risk factors for suicidal ideation(β=0.289, P=0.013, OR=1.335, 95%CI=1.063-1.676), RBANS attention factor(β=-0.161, P=0.000, OR=0.851, 95%CI=0.778-0.931)and RBANS delayed memory factor score(β=-0.151, P=0.006, OR=0.860, 95%CI=0.772-0.957)were protective factors for suicidal ideation.@*Conclusion@#Cognitive function has an impact on suicide ideation of depressive patients, mainly attention and delayed memory are protective factors for suicide ideation.
