Our objective was to investigate change in prevalence rates for mental and substance abuse disorders between early adolescence and young adulthood in a cohort of indigenous adolescents who participated in an 8-year panel study.

A growing body of research has documented associations between discrimination, anger, and delinquency, but the exact nature of these associations remains unclear. Specifically, do aggressive behaviors emerge over time as a consequence of perceived discrimination and anger? Or do adolescents who engage in aggressive behavior perceive that they are being discriminated against and become angry? We use autoregressive cross-lagged path analysis on a sample of 692 Indigenous adolescents (mean age = 12 years) from the Northern Midwest and Canada to answer these research questions. Results showed that the direction of effects went only one way; both perceived discrimination and anger were significantly associated with subsequent aggression. Moreover, early discrimination and anger each had indirect effects on aggressive behavior three years later, and anger partially mediated the association between discrimination and aggression. Perceived discrimination is but one of many strains related to unequal social position that these Indigenous youth experience, and it has important implications for the proliferation of disparities in later life.

Background This study reports prevalence and comorbidty of five DSM-III-R diagnoses (alcohol abuse, alcohol dependence, drug abuse, major depressive episode, and generalized anxiety disorder) among American Indian and Canadian First Nations parents/caretakers of children aged 10–12 years from the Northern Midwest United States and Canada. Lifetime prevalence rates were compared to adults in the National Comorbidity Survey (NCS) and Southwest and Northern Plains cultures from the AI-SUPERPFP study. Method Native interviewers used computer-assisted personal interviews to administer the University of Michigan Composite International Diagnostic Interview (UM-CIDI) to 861 tribally enrolled parents and caretakers (625 females; 236 males) of 741 tribally enrolled children aged 10–12 years. Fathers/male caretakers ranged in age from 21 years to 68 years with an average age of 41 years; mothers/female caretakers ranged in age from 17 years to 77 years with an average of 39 years. Results About three-fourths (74.6%) of the adults met lifetime criteria for one of the five disorders; approximately one-third (31.6%) met lifetime criteria for two or more of the five disorders. Prevalence of the substance use disorders was higher than those in the general population (NCS); prevalence of internalizing disorders (major depressive disorder and generalized anxiety disorder) was very similar to those in the general population. Prevalence rates for alcohol abuse among the Northern Midwest adults were higher than those reported for Southwest and Northern Plains Tribes, but rates of alcohol dependency were very similar across cultures. Conclusions The higher prevalence rates for some mental disorders found for the Northern Midwest are discussed in terms of potential method variance. The Northern Midwest results reflect unique patterns of psychiatric disorders in the ubiquity of substance abuse disorders and the co-occurrence of substance abuse disorders with internalizing disorders. Reducing lifetime occurrences of substance abuse disorders would have an enormous positive impact on the mental health of this population.

A statewide sample of 1735 Iowa residents, approximately half of whom were victims of the 1993 Midwest Floods, participated in interviews 1 year prior to, and 30 to 90 days after, the disaster. Employing a rigorous methodology including both control‐group comparisons and predisaster assessments, we performed a systematic evaluation of the disaster's impact. Overall, the disaster led to true but small rises in depressive symptoms and diagnoses 60–90 days postflood. The disaster–psychopathology effect was not moderated by predisaster depressive symptoms or diagnostically defined depression; rather, predisaster symptoms and diagnoses uniquely contributed to increases in postdisaster distress. However, increases in symptoms as a function of flood impact were slightly greater among respondents with the lowest incomes and among residents living in small rural communities, as opposed to on farms or in cities. Implications for individual‐ and community‐level disaster response are discussed.

This study examines factors that contribute to depressive symptoms and to co-occurring depression, substance abuse, and conduct problems among 602 runaway and homeless adolescents. The respondents were interviewed in shelters, drop-in centers, and directly on the streets in four Midwestern states (Missouri, Iowa, Nebraska, and Kansas). Results indicate that although family-of-origin factors contribute to depressive symptoms and comorbidity among runaway and homeless adolescents, experiences and behaviors when the adolescents are on their own also have powerful effects. The authors discuss the findings from a life-course perspective focusing on mechanisms through which street experiences accentuate or amplify already high levels of psychological distress and behavioral problems among this population of young people.
