Social comparison is a socio-cognitive process that can increase risk for suicidal thoughts through feelings of defeat and entrapment. However, its role as a risk factor for Asian, Black, and multiracial individuals remains unclear. This study examined whether social comparison and subjective social rank (one’s perceived position derived from social comparison) predict suicidal thoughts via defeat and entrapment, particularly for racially minoritized college students. College students from predominantly White institutions completed online surveys at baseline and one-month follow-up. Using data from 409 participants, path analyses showed that perceived social rank is a risk factor for suicidal thoughts across racial groups, leads to defeat and entrapment only for White students.
