Objective:To explore the depressive patients'implicit self-esteem level and its stability.Methods: IAT(Implicit Association test)and SES(self-esteem scale)were used to measure the depressive patients'implicit self-esteem and explicit self-esteem(n=30).Both 2?2 design between subjects(patients and normal controls) and the failure feedback task were employed to explore the implicit self-esteem's stability of depressive patients.Re- sults:(1)The implicit self-esteem of the two groups had no difference(270.2?103.7/283.3?172.1,t'=0.35, P=0.72).(2)The explicit self-esteem was lower than the implicit self-esteem in depressed persons(-0.05?0.74/-0.62?0.86,z=2.38,P
