Abstract: Background　Available studies show that depression is one of the important factors affecting college students' mental health.Therefore，it is necessary to conduct effective interventions for college students with depression.Objective　To investigate the effect of meridian-following meditation on depression in college students.Methods　In April 2018，60 cases were selected by the survey results with the Zung Self-rating Depression Scale（SDS）from the undergraduates of a university who voluntarily participated in the study of our meridian-following meditation group.According to the sex ratio，they were randomly divided into meridian-following meditation group and resting training group by the method of random number table，receiving 4-week meridian-following meditation intervention，and 4-week resting training intervention，respectively.All of them completed the SDS before and after the intervention，and the E-prime emotional pictures task.Pre- and post-intervention measured parameters and differences between pre-and post-intervention measured parameters were obtained.Results　Pre- and post-intervention emotional valences evoked by watching positive，neutral and negative pictures in both groups showed no significant differences（P>0.05）．Differences between pre- and post-intervention emotional valences evoked by watching positive，neutral and negative pictures in both groups were not significant（P>0.05）．Compared with baseline，post-intervention emotional valences evoked by watching positive，neutral and negative pictures showed insignificant changes in resting training group（P>0.05），but emotional valence evoked by watching positive pictures decreased，and that evoked by watching negative pictures increased in the meridian-following meditation group（P<0.05）．There was no significant difference in pre-intervention SDS score between the two groups（P>0.05）．Meridian-following meditation group showed lower post-intervention SDS score and greater differences between pre- and post-intervention SDS scores than the resting training group（P<0.05）．SDS scores decreased significantly after intervention in both groups（P<0.05）．Conclusion　Meridian-following meditation can reduce the depression level in college students，possibly because it can change people's emotional cognition and sleep quality，and make people become peaceful.
