Suicidal ideation represent a serious mental health challenge among young people, with a particularly alarming rise in recent years in Iran. Research indicates that childhood trauma, individual responses to such adversity, and secondary emotions—known as meta-emotions—play a significant role in the development of suicidal ideation. Given the psychological and social pressures faced by university students, examining the psychological factors underlying these thoughts is essential.



This study aims to predict suicidal thoughts in Iranian students based on the type of childhood trauma and meta-emotions, while considering the mediating role of trauma response styles. The research adopts a correlational design with a quantitative approach. Standardized instruments will be used to measure the variables, and data will be analyzed using structural equation modeling (SEM).



The significance of this study lies in its contribution to bridging the gap in local research by offering a culturally grounded understanding of the psychological predictors of suicidal ideation. The findings may inform the development of trauma-informed psychological interventions, the teaching of meta-emotional skills, and the expansion of university counseling services tailored to the needs of at-risk students.
