Objective : Previous studies have shown that depression, anxiety and embitterment are highly related to suicide. This study aims to investigate the mediating effect of embitterment between depression, anxiety and suicide.

Methods : A total of 174 participants with depressive and anxiety disorders were evaluated with STAI-S, STAI-T, PHQ-9, PTED scale, SSI and suicide attempt history. A mediation analysis using bootstrapping was utilized in order to estimate the indirect effects of depression and anxiety on suicide through embitterment.

Results : Embitterment significantly mediated the relationship between depression and suicidal ideation [b=0.291, 95% CI(0.18, 0.40)], and also it mediated the relationship between depression and suicide attempt [b=0.066, 95% CI(0.02, 0.16)]. Although a direct effect of anxiety on suicide attempt was not significant, but embitterment significantly mediated the relationship between anxiety and suicide attempt

Conclusion : This suggests that embitterment may be a significant important factor to consider in the relationship between depression, anxiety and suicide. Understanding the mediating role of embitterment on suicide may helpful to prevent suicide.
