Relationship between anhedonia and suicidal ideation in patients with first-episode untreated depressive disorder
Objective:To explore the relationship between anhedonia and suicidal ideation and the effects of anhedonia on suicidal ideation in patients with first-episode untreated depressive disorder.Methods:Totally 106 in-patients who met the diagnostic criteria for depressive disorder of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)were invited to participate in the study.Anhedonia,depressive symptoms and sui-cidal ideation were assessed with the Snaith-Hamilton Pleasure Scale(SHAPS),Hamilton Depression Scale(HAMD)and Beck Scale for Suicide Ideation(BSI),respectively.If both items 4 and 5 of BSI were 0,it indicated non-suicidal ideation,the subjects were divided into a group of suicidal ideation(n=66)and a group non-suicidal ideation(n=40).Spearman correlation analysis and multivariate binary logistic regression analysis were used for a-nalysis.Results:The correlation between the scores of SHAPS and HAMD was not statistically significant(P>0.05).The SHAPS scores were positively correlated with the BSI scores(r=0.70,P<0.01).Meanwhile,binary logistic regression analysis showed that anhedonia was one of a risk factor for suicidal ideation(OR=2.34,95%CI:1.58-3.47,P<0.001).Conclusion:It suggests that anhedonia maybe partially independent of other depres-sive symptoms and it is one of the risk factors for suicidal ideation in first-episode untreated patients with depressive disorder.
