Homelessness-Related Traumatic Events and PTSD Among Women Experiencing Episodes of Homelessness in Three U.S. Cities.

In this article, we report the prevalence of traumatic events (TEs), lifetime and 12-month posttraumatic stress disorder (PTSD) among 148 women experiencing homelessness in 3 midsized cities in the United States (Omaha, NE, Pittsburgh, PA, and Portland, OR). The women ranged in age from 19 to 54 years with an average age of 38.89 years (SD = 10.18). The sample was 42.6% White/European American. We investigated the mediation of distal TEs (i.e., childhood maltreatment) by more proximal TEs associated with being homeless (i.e., homelessness-related stressors) for meeting diagnostic criteria for 12-month PTSD. Results indicated that 42.6% of the women met criteria for lifetime PTSD and 39.7% met criteria for past-year PTSD. The number of TEs reported ranged from 0 to 16 in order of prevalence with a median of 6 TEs. The correlations between childhood maltreatment and 12-month PTSD ranged from .16 to .20 and the correlations between homelessness-related stressors and 12-month PTSD ranged from .21 to .30. The mediation analysis was consistent with the association between childhood maltreatment and past-year PTSD being fully mediated by homelessness-related trauma.

Mental and substance use disorders from early adolescence to young adulthood among indigenous young people: final diagnostic results from an 8-year panel study.

OBJECTIVE: 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. METHOD: The data are from a lagged, sequential study of 671 indigenous adolescents (Wave 1) from a single culture in the Northern Midwest USA and Canada. At Wave 1 (mean age 11.3 years, Wave 4 (mean age 14.3 years), Wave 6 (mean age 16.2 years), and at Wave 8 (mean age 18.3 years) the tribally enrolled adolescents completed a computer-assisted personal interview that included DISC-R assessment for 11 diagnoses. Our yearly retention rates by diagnostic wave were: Wave 2, 94.7 %; Wave 4, 87.7 %; Wave 6, 88.0 %; Wave 8, 78.5 %. RESULTS: The findings show a dramatic increase in lifetime prevalence rates for substance use disorders. By young adulthood, over half had met criteria of substance abuse or dependence disorder. Also at young adulthood, 58.2 % had met lifetime criteria of a single substance use or mental disorder and 37.2 % for two or more substance use or mental disorders. The results are compared to other indigenous diagnostic studies and to the general population. CONCLUSIONS: A mental health crisis exists within the indigenous populations that participated in this study. Innovations within current mental health service systems are needed to address the unmet demand of adolescents and families.

Self-Reported Arrests Among Indigenous Adolescents: a Longitudinal Analysis of Community, Family, and Individual Risk Factors.

PURPOSE: North American indigenous (American Indian/Canadian First Nations) adolescents are overrepresented in the juvenile justice systems in the USA and Canada. One explanation advanced for disproportionate numbers of racial and ethnic minorities in the justice systems is the unequal distribution of risk factors across groups. The purpose of this study is to investigate the prevalence of and risk factors for first arrest within a population sample of indigenous adolescents. METHODS: The data come from an 8-year longitudinal panel study of indigenous youth (n = 641) from the northern Midwest and Canada, spanning ages 10 to 19 years. We used a discrete-time survival model to estimate the overall hazard of first arrest and change in the arrest hazard over time and included both time-invariant and time varying risk factors. RESULTS: The risk of arrest increased over time, although the largest increase occurred between waves 3 and 4, when the adolescents averaged 13.1 and 14.3 years, respectively. The youth had a 55 % probability of being arrested at least once by the end of the study. Of the time-invariant risk factors, exposure to violence, parent arrest, age, and income were associated with overall risk of first arrest. Three time-varying risk factors (alcohol use, marijuana use, and peer delinquency) were associated with changes in the risk of first arrest. CONCLUSIONS: Being arrested carries significant repercussions for young people, including involvement in the juvenile justice system as well as consequences into adulthood. Communities must go beyond programs that target problem behaviors because community, family, and peer factors are also important.

Interactive effects within the prototype willingness model: Predicting the drinking behavior of indigenous early adolescents.

Drawing on the Prototype/Willingness Model of Adolescent Risk Behavior, we used longitudinal data collected from North American Indigenous early adolescents (ages 10-12 years) to examine the interactive effects of favorable drinker prototypes, perceived drinking norms, and past-year drinking behavior on subsequent drinking behavior (i.e., drinking behavior 1 year later and growth in drinking behavior from 1-5 years later). We found that the positive association between favorable drinker prototypes and drinking 1 year later was strongest for adolescents who were high in past-year drinking and perceived low drinking norms. The interaction pattern for growth in drinking was more complex and suggested an important pattern; specifically, favorable drinker prototypes were positively associated with drinking 5 years later, but only for adolescents who reported no past-year drinking and perceived low drinking norms. The theoretical and practical implications of these results are discussed.
