Effects of emotion on cognitive function in depression / 中华行为医学与脑科学杂志

ABSTRACT

Objective To explore the effects of emotion on cognitive function in patients with depression.Methods Self-rating anxiety scale(SAS),self-rating depression scale (SDS) and the typical one-back task were done by 397 patients with depression in Peking University Sixth hospital out-patient and hospitalization during 2012 June to 2013 October.Results Both of the SAS standard score (51.81 ± 11.50) and SDS standard score (62.94 ± 13.06) were significantly related (r=0.125,P＜0.05.r=0.176,P＜0.01) to the reaction time of one-back task ((590.27±213.96)ms),and the correlation between SAS standard score and SDS standard score was significant (r=0.682,P＜0.01).The results of regression analysis suggested that,only SDS score could predict the reaction time of one-back task.Conclusion The emotion of anxiety and depression in patients with depression are correlated with cognitive function,and the emotion of depression is the main factor to affect the cognitive function.
