Based on cut-off scores, 112 students (56 with high and 56 with low suicidal ideation) were selected using purposive sampling to ensure balanced group comparison. Participants also completed the Childhood Trauma Questionnaire&ndash;Short Form (CTQ-SF) and the Mentalization Scale (MentS). Data were analyzed using multivariate analysis of variance (MANOVA).<br> <strong>Results:</strong> Students with high suicidal ideation experienced more childhood abuse and exhibited poorer mentalization capacities across all domains than their low-ideation peers.<br> <strong>Conclusion:</strong> The results highlight the intertwined influence of childhood trauma and impaired mentalization on suicidal ideation. Interventions aimed at reducing suicide risk among young adults should target both trauma recovery and enhancement of reflective functioning.</span></span></span></div> <span style="font-size:11pt"><span style="line-height:115%"><span calibri="" style="font-family:"><b><span style="font-size:14.0pt"><span style="line-height:115%"><span style="font-family:"Times New Roman",serif"></span></span></span></b></span></span></span> Suicidal ideation, Childhood abuse, Mentalization, Students 0 0 http://jpcp.uswr.ac.ir/browse.php?a_code=A-10-1084-1&slc_lang=en&sid=1 Ehsan Akbari eakbari72@gmail.com No Department of Psychology, Faculty of Humanities, Shahed University, Tehran, Iran.
