The prevalence of suicidal behaviors among Northern Plains American Indians

This study examined the prevalence of suicidal behaviors among 1,638 Northern Plains American Indians ages 15-57. Age and gender patterns were investigated as was comorbidity with psychiatric and substance use disorders. Data from a population-based survey indicated that suicidal behaviors were more frequently reported among females than males and among younger respondents than older respondents. In addition, suicidal behaviors were associated with depressive disorders, PTSD, substance abuse/dependence, and violent ideation/aggression. Results underscore the importance of effective and acceptable alcohol, drug, and mental health services in reducing the rates of suicidal behaviors in American Indian communities.     

Factors Associated with Suicide Ideation among American Indian Adolescents: Does Culture Matter?

Data from self-report surveys of 1,353 high school students representing three culturally distinct American Indian tribes were analyzed for tribal differences in factors associated with suicidal ideation. In the multivariate analysis, no single correlate of suicide ideation was common to all three tribes. The correlates of suicide ideation were consistent with each tribe's social structure, conceptualization of individual and gender roles, support systems, and conceptualization of death. These results underscore the heterogeneity of suicide ideation across three distinct American Indian tribes consistent with their cultural heterogeneity. Suicide prevention and screening programs may be difficult to adapt from one tribe to another.
