Although one-third of enrolled U.S. undergraduate college students are non-White, little is known about risk factors for suicidal behavior among racial and ethnic minority students. Thus, we set out to determine psychosocial factors associated with recurrent suicidal ideation among racially and ethnically diverse college students with a history of suicide attempt. From 2012Ð2013, 1,734 racially and ethnically diverse college students completed an on-line survey of suicidal behavior and associated factors. Depression, hopelessness, rejection sensitivity, and mindfulness, as well as past-year discrimination, ethnic identification, and acculturative stress were measured using well-validated self-report instruments. The Beck Scale for Suicide Ideation was used to assess current suicidal ideation. A subsample of 118 college students who self-reported a past suicide attempt were selected for the current analysis. Logistic regression analysis was used to test associations between risk factors and the presence of suicidal ideation, and linear regression analysis was used to test factors associated with suicidal ideation severity among those who reported current suicidal ideation. Depression was significantly related to both the presence and severity of current suicidal ideation. Mindfulness, and in particular awareness of present moment experience, was also inversely associated with ideation severity. We found depression and mindlessness were associated with suicidal ideation severity among a sample of diverse college students at high risk for suicidal behavior due to a past suicide attempt. Factors unique to the minority experience, such as acculturative stress, were not associated with current suicidal ideation. Implications for suicide prevention are discussed.
