Trajectories of substance use among young American Indian adolescents: patterns and predictors

Substance use often begins earlier among American Indians compared to the rest of the United States, a troubling reality that puts Native youth at risk for escalating and problematic use. We need to understand more fully patterns of emergent substance use among young American Indian adolescents, risk factors associated with escalating use trajectories, and protective factors that can be parlayed into robust prevention strategies. We used growth mixture modeling with longitudinal data from middle-school students on a Northern Plains reservation (Wave 1 Nxa0=xa0381, M age at baselinexa0=xa012.77, 45.6xa0% female) to identify subgroups exhibiting different trajectories of cigarette, alcohol, and marijuana use. We explored how both risk (e.g., exposure to stressful events, deviant peers) and protective (e.g., positive parent–child relationships, cultural identity) factors were related to these trajectories. For all substances, most youth showed trajectories characterized by low rates of substance use (nonuser classes), but many also showed patterns characterized by high and/or escalating use. Across substances, exposure to stress, early puberty, and deviant peer relationships were associated with the more problematic patterns, while strong relationships with parents and prosocial peers were associated with nonuser classes. Our measures of emergent cultural identity were generally unrelated to substance use trajectory classes among these young adolescents. The findings point to the importance of early substance use prevention programs for American Indian youth that attenuate the impact of exposure to stressful events, redirect peer relationships, and foster positive parent influences. They also point to the need to explore more fully how cultural influences can be captured.

Patterns of Substance Use Initiation among Young Adolescents in a Northern Plains American Indian Tribe

Background: Substantial evidence documents problematic substance use in Northern Plains American Indian communities. Studies suggest that disparities can be traced to disproportionate rates of early substance use, but most evidence comes from the retrospective reports of adults or older adolescents. Objective: To use a prospective longitudinal design to examine substance use initiation patterns as they emerge among young American Indian adolescents. Methods: Four waves of data were collected across three consecutive school years from middle school students on a Northern Plains reservation (N = 450). Discrete-time survival analyses were used to estimate risks of initiation of cigarettes, alcohol, and marijuana from age 10 to 13. Results: Risk for cigarette initiation was relatively high at age 10 and stable until age 13. Marijuana risk was low at age 10 but increased sharply by age 12. Alcohol initiation lagged, not surpassing risk for cigarette initiation until age 13 and remaining below risk for marijuana initiation throughout middle school. Hazards for girls trended higher than those for boys across all substances, but differences did not reach significance. Conclusion: Initiation patterns among these American Indian adolescents differed from patterns reported in other US groups, particularly with respect to deviation from the sequence characterized the initiation of marijuana before alcohol that is predicted by the gateway theory. Scientific Significance: Findings suggest that prevention efforts with youth in this community should begin early with a primary focus on marijuana use. They also suggest the importance of examining sequences of substance initiation among youth in other American Indian communities.

Family Chaos and Child Functioning in Relation to Sleep Problems Among Children at Risk for Obesity

This study evaluated the influence of child and family functioning on child sleep behaviors in low-income minority families who are at risk for obesity. A cross-sectional study was utilized to measure child and family functioning from 2013 to 2014. Participants were recruited from Head Start classrooms while data were collected during home visits. A convenience sample of 72 low-income Hispanic (65%) and African American (32%) families of preschool-aged children were recruited for this study. We assessed the association of child and family functioning with child sleep behaviors using a multivariate multiple linear regression model. Bootstrap mediation analyses examined the effects of family chaos between child functioning and child sleep problems. Poorer child emotional and behavioral functioning related to total sleep behavior problems. Chaos associated with bedtime resistance significantly mediated the relationship between Behavioral and Emotional Screening System (BESS) and Bedtime Resistance. Families at high risk for obesity showed children with poorer emotional and behavioral functioning were at higher risk for problematic sleep behaviors, although we found no link between obesity and child sleep. Family chaos appears to play a significant role in understanding part of these relationships. Future longitudinal studies are necessary to establish causal relationships between child and family functioning and sleep problems to further guide obesity interventions aimed at improving child sleep routines and increasing sleep duration.

Lifetime Prevalence of Posttraumatic Stress Disorder in Two American Indian Reservation Populations

Posttraumatic stress disorder (PTSD) has been found to be more common among American Indian populations than among other Americans. A complex diagnosis, the assessment methods for PTSD have varied across epidemiological studies, especially in terms of the trauma criteria. Here, we examined data from the American Indian Service Utilization, Psychiatric Epidemiology, Risk and Protective Factors Project (AI-SUPERPFP) to estimate the lifetime prevalence of PTSD in two culturally distinct American Indian reservation communities, using two formulas for calculating PTSD prevalence. The AI-SUPERPFP was a cross-sectional probability sample survey conducted between 1997 and 2000. Southwest (n = 1,446) and Northern Plains (n = 1,638) tribal members living on or near their reservations, aged 15-57 years at time of interview, were randomly sampled from tribal rolls. PTSD estimates were derived based on both the single worst and 3 worst traumas. Prevalence estimates varied by ascertainment method: single worst trauma (lifetime: 5.9% to 14.8%) versus 3 worst traumas (lifetime, 8.9% to 19.5%). Use of the 3-worst-event approach increased prevalence by 28.3% over the single-event method. PTSD was prevalent in these tribal communities. These results also serve to underscore the need to better understand the implications for PTSD prevalence with the current focus on a single worst event.

THE SURVEY OF WELL-BEING OF YOUNG CHILDREN: RESULTS OF A FEASIBILITY STUDY WITH AMERICAN INDIAN AND ALASKA NATIVE COMMUNITIES

This study examined the feasibility of the Survey of Well-Being of Young Children (SWYC), a new screener for socioemotional and developmental problems and family risk in children birth to age 5 years, for use in American Indian and Alaska Native (AIAN) communities. A Community of Learning within the Tribal Early Childhood Research Center, composed of university researchers, tribal early childhood program staff and evaluators, and federal partners, utilized a community-based participatory research approach to guide this qualitative study. Thirty-two focus groups and 20 key informant interviews (N = 199) were conducted with staff from Head Start, Home Visiting, and Child Care programs; pediatricians; behavioral health providers; parents of young children; tribal leaders; and other stakeholders in seven diverse AIAN communities. Three themes emerged: (a) a strong need to screen early for socioemotional and developmental problems and family risk; (b) the importance of a carefully designed process for screening; and (c) the importance of examining the content of the SWYC for cultural fit specific to tribal communities. Findings support two recommendations: (a) the development of guidelines for using the SWYC in tribal early childhood settings and (b) a full-scale validation study to determine appropriate use with and norms for children in tribal communities.

Research with American Indian and Alaska Native populations: Measurement matters

ABSTRACT Research is an important tool in addressing myriad American Indian and Alaska Native (AIAN) health disparities; however, tensions exist between common empirical measurement approaches that facilitate cross-cultural comparisons and measurement specificity that may be more valid locally and/or culturally appropriate. The tremendous diversity of AIAN communities, small population sizes of distinct AIAN cultural groups, and varying cultural contexts and worldviews should influence measurement decisions in health research. We provide a framework for guiding measurement in collaboration with AIAN communities using examples from substance abuse research for illustration. Our goal is to build upon ongoing efforts to advance measurement validity for AIAN research by engaging community–researcher partnerships and critical thinking in the selection, adaptation, creation, and implementation of measures.

APPROACHES TO THE EVALUATION OF CULTURAL ADAPTATIONS OF HOME VISITING IN TRIBAL COMMUNITIES: Evaluation Approaches for Cultural Adaptations

The research that underlies evidence-based practices is often based on relatively homogenous study samples, thus limiting our ability to understand how the study findings apply in new situations as well as our understanding of what might need to be adapted. In a preliminary effort to address those gaps, the requirements for the Tribal Maternal Infant and Early Childhood Home Visiting Program (MIECHV) included the expectation that grantees design and implement rigorous evaluations to address local priorities and to help build the knowledge base regarding the use of evidence-based home-visiting programs in tribal communities. A priority that emerged across many Tribal MIECHV grantees was to determine the added benefit of the cultural adaptations that they were making to their home-visiting programs. While there is literature to describe recommended processes for making cultural adaptations to evidence-based programs themselves, there are very few guidelines for evaluating these adaptations. In this article, we review the varied evaluation approaches utilized by Tribal MIECHV grantees and provide three case examples of how evaluators and tribal communities worked together to articulate evaluation questions and choose appropriate and feasible evaluation designs. The lessons derived from these Tribal MIECHV evaluation experiences have implications for the role of the evaluator in diverse communities across the country evaluating home visiting and other evidence-based practices in settings characterized by unique cultural contexts.

MEASUREMENT ISSUES IN HOME-VISITING RESEARCH WITHIN TRIBAL COMMUNITIES: CHALLENGES AND STRATEGIES: Measurement Issues in Tribal Home-Visiting Research

In this article, Tribal Maternal, Infant, and Early Childhood Home Visiting (MIECHV) grantees share strategies they have developed and adopted to address the most common barriers to effective measurement (and thus to effective evaluation) encountered in the course of implementation and evaluation of their home-visiting programs. We identify key challenges in measuring outcomes in Tribal MIECHV Programs and provide practical examples of various strategies used to address these challenges within diverse American Indian and Alaska Native cultural and contextual settings. Notably, high-quality community engagement is a consistent thread throughout these strategies and fundamental to successful measurement in these communities. These strategies and practices reflect the experiences and innovative solutions of practitioners working on the ground to deliver and evaluate intervention programs to tribal communities. They may serve as models for getting high-quality data to inform intervention while working within the constraints and requirements of program funding. The utility of these practical solutions extends beyond the Tribal MIECHV grantees and offers the potential to inform a broad array of intervention evaluation efforts in tribal and other community contexts.

Pathways of Adaptation: Two Case Studies with One Evidence-Based Substance Use Prevention Program Tailored for Indigenous Youth

Indigenous communities often face disproportionate challenges across a variety of health domains, and effective prevention strategies are sorely needed. Unfortunately, evidence is scant regarding what approaches are effective for these communities. A common approach is to take an evidence-based practice or program with documented effectiveness in other populations and implement it with Indigenous populations. While a science of intervention adaptation is emerging, there remains little guidance on processes for adaptation that strategically leverage both existing scientific evidence and Indigenous prevention strategies. In this paper, two case studies illustrate promising practices for adaptation, documenting the approaches of two research teams funded under the National Institutes of Health’s initiative to support Intervention Research to Improve Native American Health (IRINAH). These teams worked with distinct Indigenous populations in the USA and Canada to culturally adapt the same prevention program, the Iowa Strengthening Families Program for Parents and Youth 10–14. The approaches of these two teams and the programs that resulted are compared and contrasted, and critical elements of adaptation in partnership with Indigenous communities are discussed.

Advancing Scientific Methods in Community and Cultural Context to Promote Health Equity: Lessons from Intervention Outcomes Research with American Indian and Alaska Native Communities.

Evidence-based interventions hold promise for reducing gaps in health equity across diverse populations, but evidence about effectiveness within these populations lags behind the mainstream, often leaving opportunities to fulfill this promise unrealized. Mismatch between standard intervention outcomes research methods and the cultural and community contexts of populations at greatest risk presents additional challenges in designing and implementing rigorous studies; these challenges too often impede efforts to generate needed evidence. We draw on experiences with American Indian and Alaska Native communities to illustrate how consideration of culture and context can constructively shape intervention research and improve the quality of evidence produced. Case examples from a partnership with one American Indian community highlight opportunities for increasing alignment in intervention development, research design, and study implementation to maximize both validity and feasibility. We suggest that responsively tailoring intervention outcomes research to cultural and community contexts is fundamental to supporting health equity.
