Abstract Background: The dark triad personality (DTP) is associated with an increase in adverse consequences related to risky behaviors. While studies have concentrated on the interpersonal issues associated with DTPs (Machiavellianism MV, narcissism NS, and psychopathy PP), there is a scarcity of research examining the links between DTP and intrapersonal challenges, particularly in relation to suicide. Aim: The study aims to assess the relationship between DTP and suicidal behavior (SB). Specifically, the study examines the chain mediating effects of negative affectivity (NA) and detachment (DET) in the association between these DTPs and SB among college students. Materials and Methods: The study employed a cross-sectional quantitative design and included 321 college students aged 18–29 years, comprising both genders. Participants were recruited using a convenience sampling method through online Google Forms. Data were collected using standardized instruments, including Short Dark Triad, SB Questionnaire, and Personality Inventory for DSM-5–Short Form (PID-5-SF). Results: The prevalence of SB was 27.4%. Specifically, the rates were 12.4% for male students and 14.9% for female students, with no significant gender difference. There was a significant positive association found between MV, NS, PP, NA, DET, and SB ( P < 0.01). The direct effect of DTPs on SB was significant. However, the total indirect effect of DTPs on SB through NA and DET was significant, indicating that both NA and DET serially and partially mediated this association among college students. Conclusion: The present study findings underscore the complex interplay between DTPs, emotional processes, and SB among college students.
