Diagnostic prevalence rates from early to mid-adolescence among indigenous adolescents: first results from a longitudinal study.

OBJECTIVE Investigate change in prevalence rates for mental and substance abuse disorders between early and mid-adolescence among a cohort of indigenous adolescents. METHOD The data are from a lagged, sequential study of 651 indigenous adolescents from a single culture in the northern Midwest United States and Canada. At waves 1 (ages 10-12 years) and 4 (ages 13-15 years), one adult caretaker and one tribally enrolled adolescent completed a computer-assisted personal interview that included Diagnostic Interview Schedule for Children-Revised assessment for 11 diagnoses. Multivariate analyses investigate effects of wave 1 adolescent diagnosis and wave 1 biological mother diagnosis (University of Michigan Composite International Diagnostic Interview) on wave 4 diagnostic outcomes. RESULTS The findings show a increase in prevalence rates for substance abuse disorders and conduct disorders between ages 10 and 12 years and 13 and 15 years among indigenous adolescents, with these disorders affecting more than one fourth of the children. The rate of lifetime conduct disorder is about twice that expected in general population studies (23.4% versus 5%-10%), and the rate of lifetime substance abuse disorder (27.2%) is three times that reported in the 2004 National Survey on Drug Use and Health (9.4%) for individuals 12 years or older. Prevalence rates for any single mental or substance use disorder (44.8 lifetime) for the 13- to 15-year-olds are similar to the lifetime prevalence rates reported in the National Comorbidity Survey-Replication (46.4%) for individuals 18 years and older. CONCLUSIONS A mental health crisis exists on the indigenous reservations and reserves that participated in this study. Current service systems are overwhelmed and unable to meet the demands placed upon them.

A Comparison Study of Psychiatric and Behavior Disorders and Cognitive Ability Among Homeless and Housed Children

This study examined the association of homelessness and related factors with child psychiatric and behavior disorders (diagnosed with structured diagnostic interviews) and child cognitive ability (on the Kaufman Brief Intelligence Test) in a randomly selected sample of 157 homeless children and their mothers and a comparison of 61 housed children and their mothers. Homeless children had more disruptive behavior disorders and lower cognitive scores than housed children. In multivariate analyses, maternal verbal scores and child nonverbal scores were associated with child verbal ability; maternal education, homelessness, and child nonverbal scores were related to child behavior disorders.

Positive family relationships and religious affiliation as mediators between negative environment and illicit drug symptoms in American Indian adolescents

The present study tests how positive family relationships and religious affiliation mediate between negative familial and social environments, and adolescent illicit drug abuse/dependence symptoms. The theoretical framework is based on an integration of two theories: the ecological model of human development (Bronfenbrenner, 1979) and the social development model (Hawkins & Weis, 1985). We used a stratified random sample of 401 American Indian adolescents. A path analysis tested the integrative theoretical model. Findings showed that positive family relationships mediated the negative impact of addicted family members, violence victimization, and negative school environment on illicit drug abuse/dependence symptoms. Religious affiliation mediated the negative effect of deviant peers on positive family relationships. Intervention and prevention efforts may benefit from promoting positive family relationships and religious affiliation to reduce the impact of complex familial and social problems on illicit drug symptoms.

Understanding tobacco use among urban African American adolescents living in public housing communities: a test of problem behavior theory.

This study was guided by Jessor and Jessors problem behavior theory (PBT) to test the relative effects of personality, perceived environment and behavior system variables on urban teen tobacco use. A sample of 518 urban African American youth residing in public housing communities in three large U.S. cities was utilized. Our results provide partial support for PBT in this study. Personality system variables (i.e., positive attitudes toward tobacco use, and depressive affect, cause and outcome indicators) and behavior system variables (i.e., delinquent behaviors) significantly predicted adolescent tobacco use. Depressive effect and cause indicators were stronger than depressive outcome indicators in predicting the extent of tobacco use. Additionally, age positively moderated the impact of positive attitudes about tobacco use on the extent of adolescent tobacco use. However, perceived environment system variables (e.g., exposure to delinquent peers) did not predict such use. This study suggests that PBT may aid in understanding adolescent tobacco use. Implications for practice and future inquiry are discussed.

Depressive symptoms, gender, and growth in cigarette smoking among indigenous adolescents.

This study reports findings from two-level growth curve modeling of cigarette smoking and depressive symptoms based on the first three waves of data from a longitudinal study of Indigenous adolescents and their parents/caretakers in the northern Midwest and Canada. The 743 adolescents were aged 10-13 years at Wave 1 and 12-15 years at Wave 3. Over the three years of the study the overall retention rate was 93%. By Wave 3, 39% of the adolescent girls and 25% of the boys had smoked cigarettes in the past 12 months. The growth curve results indicated that smoking increased for both adolescent boys and girls across time. Depressive symptoms were associated with an increase in cigarette smoking for girls but not boys.

Assessing Effects of Food Stamp Program Participation on Child Food Security in Vulnerable Households: Do Informal Supports Matter?

The Food Stamp Program (now the Supplemental Nutrition Assistance Program) is one of the largest federal welfare initiatives undertaken to address the problem of hunger and nutrient intake among households in poverty. We build on previous research by examining the effects of participating in the program on food security among children in vulnerable households using data from the Current Population Survey Food Security Supplement for 2003. We also explore the moderating effects of informal food assistance. Our results suggest that food stamp take-up and informal food assistance are important in understanding child food security in vulnerable households. Further, we note that a number of individual and household characteristics are associated with child food security. Implications for practice and scholarship are presented.

Assessing Effects of Food Stamp Program Participation on Food Security in Female-Headed Households: Do Informal Supports Matter?

The food stamp program is one of the largest federal welfare initiatives undertaken to address the problem of hunger and nutrient intake among households in poverty. We build on previous research by examining effects of participating in the program on the food security of vulnerable households (N = 23,360), using data from the Food Security Supplement to the Current Population Survey for 2003. We also explore the moderating effects of informal food assistance on this relationship. Our results suggest that food stamp-takeup and informal food assistance are important in understanding food security in vulnerable households. Also, a number of individual characteristics are associated with household food sufficiency. Implications for practice and scholarship are presented.

Use of Mental Health Services by Survivors of Intimate Partner Violence

Fifty women survivors of intimate partner violence (IPV) were recruited from a legal advocacy program to participate in a study designed to assess current rates of posttraumatic stress disorder (PTSD), depression, and alcohol and substance abuse among a sample of abused women and to examine the types of services survivors of IPV had used in the previous 12 months. In addition, the authors sought to understand how the presence of substance abuse, PTSD, and/or depression affects access and utilization of services by IPV survivors. Fifty-four percent of these IPV survivors were experiencing either PTSD, clinical depression, or both. While women with either PTSD or depression used a significantly larger number of services overall, the majority had not used any mental health services, even though they frequently reported services were accessible. Given the high rates of PTSD and depression in this sample, these abused women were clearly not receiving adequate mental health care. Furthermore, many reported having trouble accessing housing, legal services, crisis lines, and medical care—services that are fundamental to safety. Practitioners working with abused women should assess for PTSD and depression, and be prepared to either treat each condition or provide effective referrals.

Preventing Violence among Gang-Involved and High-Risk Youth in El Salvador: The Role of School Motivation and Self-Control

El Salvador, as a country of the Northern Triangle, exhibits significantly higher rates of crime and delinquency than the rest of the Latin American countries (World Bank 2011). Mass media portray transnational youth gangs in marginalized communities in Central American nations, such as El Salvador, as one of the main factors responsible for the high levels of violence. Few studies have empirically studied active youth gang members and high-risk youth in these contexts. Among the studies that have accessed active youth gang members, the focus has been on problem behaviors and risk factors analyses; little is known about what variables appear to serve as protective factors for these youth. Based on a cross-sectional sample of high-risk youth and youth gang members (n = 184) between the ages of 13 and 25 living in 10 urban communities in San Salvador, this study used linear regression modeling to analyze protective factors for three outcome variables: aggression, violence, and delinquency. Results reveal that self-control and school motivation act as important protective factors across the three domains, while school behavior is a protective factor of aggression and delinquency. Implications for community-based prevention and harm reduction policies are discussed.

A prospective, longitudinal study of cigarette smoking status among North American Indigenous adolescents

• Female Indigenous youths had higher rates of smoking than male youths over time. • Problem behavior theory guides us to identify predictors of smoking status. • Generalized estimating equation model was used to investigate longitudinal predictors of smoking status. • Family warmth and support was negatively associated with occasional smoking. • Frequent smoking was associated positively with depression symptoms and negatively with positive school activity.
