The purpose of this study was to examine psychological, substance use, and sociodemographic predictors of 12-month suicide ideation and attempts across six US racial/ethnic groups—white, Latino/a, Black, Asian or Pacific Islander (A/PI), American Indian or Alaska Native (AI/AN), and multiracial adults. Multiple logistic regression analyses were conducted for 218,765 adults who participated in the 2008–2013 National Survey on Drug Use and Health. Overall, commonly cited factors were associated with increased risk for suicide ideation and attempt for some racial/ethnic groups, but not for others. As one example, 12-month depression was associated with 12-month suicide attempt for A/PI, AI/AN, Latino/a, and white, but not for Black or multiracial adults. Alcohol abuse and dependence were also associated with suicide attempt for AI/AN, Black, and white respondents but not for other racial/ethnic groups. Risk factors for suicide ideation and attempt may not increase risk universally. More theoretically supported research is needed.
