Psychological Strain and Suicide Rumination Among University Students: Exploring the Mediating and Moderating Roles of Depression, Resilient Coping, and Perceived Social Support.

Suicide is among the biggest causes of death in the world. In recent years, suicide rates have increased remarkably in developing countries such as Türkiye. Therefore, there is a need to understand the psychological mechanisms underlying suicidal ideation and behaviors. Within this context, this study aimed to examine the complex relationships between psychological strain and suicide rumination. : The study was conducted on 470 university students because young adults constitute the largest suicide risk group in Türkiye. : The findings showed that psychological strain was a significant predictor of suicide rumination. Additionally, depression was found to play a mediating role between psychological strain and suicide rumination. Furthermore, both resilient coping and perceived social support were shown to play a moderating role in the relationships among psychological strain, depression, and suicide rumination. The results confirmed the Strain Theory of Suicide in a sample from Türkiye. : These findings are expected to contribute to psychologists, psychiatrists and public health specialists' development of suicide prevention and intervention programs for university students. These suicide prevention and intervention efforts may focus on enhancing resilient coping and perceived social support in combating psychological strain and depression.
