Risk and Promotive Factors Related to Cannabis Use Among American Indian Adolescents.

Reservation-dwelling American Indian adolescents are at exceedingly high risk for cannabis use. Prevention initiatives to delay the onset and escalation of use are needed. The risk and promotive factors approach to substance use prevention is a well-established framework for identifying the timing and targets for prevention initiatives. This study aimed to develop predictive models for the usage of cannabis using 22 salient risk and promotive factors. Models were developed using data from a cross-sectional study and further validated using data from a separate longitudinal study with three measurement occasions (baseline, 6-month follow-up, 1-year follow-up). Application of the model to longitudinal data showed an acceptable performance contemporaneously but waning prospective predictive utility over time. Despite the model's high specificity, the sensitivity was low, indicating an effective prediction of non-users but poor performance in correctly identifying users, particularly at the 1-year follow-up. This divergence can have significant implications. For example, a model that misclassifies future adolescent cannabis use could fail to provide necessary intervention for those at risk, leading to negative health and social consequences. Moreover, supplementary analysis points to the importance of considering change in risk and promotive factors over time.

Nicotine use among reservation-area American Indian adolescents compared with a national sample.

BACKGROUND: Past research has found significant nicotine use disparities for reservation-area American Indian adolescents when compared to national levels. However, adolescent nicotine use has changed markedly, with reduced smoking and rapid increases in nicotine vaping. This study presents 2021-2022 prevalence estimates of tobacco product use, perceived harm and availability for reservation-area American Indian youth, with comparisons to the Monitoring the Future (MTF) national study. METHODS: Participants were 8th, 10th and 12th grade students. American Indian data were 33 reservation-area schools in 2021-2022 (n=2420); MTF data were 308 schools in Spring 2022 (n=31,438). Measures were lifetime, 30-day cigarette smoking, smokeless tobacco use, and nicotine vaping; past-year nicotine vaping; daily smoking; perceived harmfulness and availability of these tobacco products. Prevalence and 95% confidence intervals were computed by grade. RESULTS: Estimated prevalence of lifetime, monthly and daily cigarette smoking among American Indian 8th and 10th graders was higher than national levels. Nicotine vaping prevalence was similar between samples. American Indian students were less likely to report tobacco product use poses great risk, but also less likely to report tobacco products are easily available. CONCLUSIONS: Although estimated smoking prevalence among American Indian 8th and 10th graders was higher than national levels, prevalence appears lower than reported in earlier studies, suggesting declining disparities. Prevalence of nicotine vaping among reservation-area American Indian adolescents generally mirrors the national population; however, a lower percentage reported regular nicotine vaping poses a serious risk. This discrepancy suggests a need for prevention and intervention efforts culturally tailored for this population.

Can High and Consistent School-Related Protective Factors Prevent Cannabis Use Among American Indian Middle School Students?

BACKGROUND: High cannabis use rates among American Indian (AI) adolescents necessitate the identification of factors that protect against early cannabis initiation. METHODS: Data collected from 279 AI middle school students attending reservation-based schools in 2018 and 2019 were analyzed. Three waves of data, with approximately 6 months between each, were used. A repeated measures latent class analysis examined a school-related protective factor index over three waves. The predictive power of lifetime cannabis use on school protection class membership was estimated, along with differences in past month cannabis use at follow-up 2 across school protection classes while holding baseline use constant. RESULTS: Four school protection classes were identified: high, moderate, low, and declining protection. Abstinence at baseline was associated with an increased odds of membership in the high protection class compared to the moderate and low protection classes. Students with consistent and high school protection throughout middle school were significantly less likely to report past month cannabis use at follow-up 2 compared to other classes. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Maintaining a high level of school protection throughout middle school substantially lowers the odds of cannabis use among AI adolescents. CONCLUSIONS: Interventions to promote school-related protective factors in this population are essential and should be designed and tested.

Intersecting sex and American Indian identity moderates school and individual correlates of binge drinking among reservation-area adolescents.

Reservation-area American Indian (AI) youth demonstrate higher rates of binge drinking (BD) than their non-AI peers. However, individual and school-level differences in BD disparities between reservation-area AI/non-AI female and male adolescents remain unexamined. This study applies an Intersectional framework to examine risk and protective factors of BD among reservation-area youth at the intersection of their sex and AI identities. A nationally representative sample of adolescents (N = 14,769; Mage = 14.6, 49% female; 61% AI) attending 103 reservation-serving schools completed a survey between 2015 and 2019. Multilevel modeling was used to examine differences in risk and protective factors of BD between AI and non-AI male and female adolescents. Our findings indicate that the effects of student and school-level risk and protective factors on adolescents' BD are driven primarily by sex within AI and non-AI groups. Implications for future confirmatory research and tailoring school-based prevention programs are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

A Comparison of COVID-19 Outcomes Between Reservation-Area American Indian and U.S. National Students.

Introduction: This study presents data from 2 population-based surveys of youth (reservation-area American Indian adolescents and U.S. adolescents) on self, family, and friend morbidity and changes in substance use and negative impacts during COVID-19. Methods: Data were obtained in spring 2021 from surveys of American Indian students living on or near reservations (8th grade, n=398; 10th grade, n=367; 12th grade, n=290) and national students from Monitoring the Future (8th grade, n=11,446; 10th grade, n=11,792; 12th grade, n=9,022). The main outcomes were COVID-19 testing, perceived morbidity/mortality, substance-use changes, and emotional changes during COVID-19. Results: The American Indian sample had a greater proportion of testing (e.g., American Indian 8th grade: 58.1% [95% CI=48.6, 68.8]; Monitoring the Future 8th grade: 43.6% [95% CI=39.8, 47.5]) and friend/family hospitalization (e.g., American Indian 8th grade: 36.2% [95% CI=26.2, 47.5]; Monitoring the Future 8th grade: 11.9% [95% CI=10.6, 13.3]). Across grades, greater proportions of the national sample reported increased anxiety, anger, boredom, loneliness, depression, worry, and trouble concentrating, whereas greater proportions of reservation-area American Indians reported decreased anxiety, loneliness, and depression. Conclusions: Findings indicate that reservation-area American Indian youth experienced unique health consequences 1 year into the COVID-19 pandemic compared with national students, illustrating the need for American Indian-specific COVID-19 public health monitoring and response.

Family ties: examining family functioning and alcohol use among American Indian youth.

Purpose: This study aims to examine a second-order latent variable of family functioning built from two established protective factors for American Indian (AI) youth, i.e. family cohesion and parental monitoring. This study then examines if family functioning is related to alcohol use frequency or age of initiation for AI youth. Additionally, this study examines if family functioning served as a moderator for the risk factor of peer alcohol use. Design/methodology/approach: Data came from the 2021 Our Youth, Our Future survey. Participants were 4,373 AI adolescents from Grades 6-12 across the contiguous USA. Structural equation modeling (SEM) was used to test the latent variable of family functioning. Structural paths and interaction terms between peer use and family functioning were added to the SEM to explore direct and moderating effects. Findings: Family cohesion and parental monitoring were best represented by a second-order latent variable of family functioning, which was related to later initiation and lower alcohol use frequency. Practical implications: The findings regarding the initiation of alcohol use may be applicable to prevention programs, with family functioning serving as a protective factor for the initiation of alcohol use. Programs working toward alcohol prevention may be best served by focusing on family-based programs. Originality/value: The latent variable of family functioning is appropriate for use in AI samples. Family functioning, which is an inherent resilience factor in AI communities, was shown to be protective against harmful alcohol use behaviors.

Profiles of Ecosystemic Resilience and Risk: American Indian Adolescent Substance Use during the First Year of the COVID-19 Crisis.

The COVID-19 pandemic has caused an unprecedented disruption to the lives of American Indian (AI) adolescents. While reservation-area AI youth already have a higher risk of substance use (SU) compared to their non-AI peers, COVID-19 stressors likely exacerbated this risk. However, COVID-19-specific and general resilience factors may have buffered against increased SU over the course of the pandemic. Using a person-centered, ecosystemic framework of resilience, we used latent profile analysis to identify ecosystemic resilience profiles indicated by general and COVID-19-specific risk and resilience factors, then examined inter-profile changes in alcohol and cannabis use after the onset of the COVID-19 pandemic from the spring of 2020 to the spring of 2021. The sample was 2218 reservation-area AI adolescents (7-12th grade; schools = 20; Mage = 15, SD = 1.7; 52% female). Four profiles emerged: Average Risk and Resilience, High Resilience, Low Resilience, and High Risk. Adolescents with a High-Risk profile demonstrated increases in alcohol and cannabis use, while High Resilience youth demonstrated decreases. These findings support the hypothesized COVID-19-specific ecosystemic resilience profiles and the application of a person-centered ecosystemic framework to identify which AI adolescents are most likely to experience substance use changes during a life-altering crisis like COVID-19.

Self-reported Illness Experiences and Psychosocial Outcomes for Reservation-Area American Indian Youth During COVID-19.

Importance: Impacts of COVID-19 on reservation-area American Indian youth are unknown and may be substantial owing to the significant COVID-19 morbidity and mortality experienced by American Indian populations. Objective: To measure self-reported illness experiences and changes in psychosocial factors during the COVID-19 pandemic among reservation-area American Indian youth. Design, Setting, and Participants: This cross-sectional study included a random sample of US schools on or near US Indian reservations during Spring 2021, stratified by region, with students in grades 6 to 12 completing cross-sectional online surveys. All enrolled self-identifying American Indian students in grades 6 to 12 attending the 20 participating schools were eligible to be surveyed; participants represented 60.4% of eligible students in these schools. Data were analyzed from January 5 to July 15, 2022. Exposures: Onset of the COVID-19 pandemic. Main Outcomes and Measures: Outcomes of interest were COVID-19 self-reported illness outcomes for self and family and close friends; perceived changes in family and friend relationships, school engagement, social isolation, and other psychological factors since the COVID-19 pandemic began; and worry over COVID-19-related health outcomes. Results: A total of 2559 American Indian students (1201 [46.9%] male; 1284 [50.2%] female; 70 [2.7%] another gender; mean [SD] 14.7 [8.9] years) were included in the analysis. Approximately 14% of the sample reported having had a test result positive for SARS-CoV-2 infection (14.3% [95% CI, 11.4%-17.6%]), a higher rate than for all cases nationally at the time of the survey. Regarding prevalence of COVID-19 among family and close friends, 75.4% (95% CI, 68.8%-80.9%) of participants reported having at least 1 family member or friend who had contracted COVID-19, while 27.9% (95% CI, 18.8%-39.3%) of participants reported that at least 1 family member or close friend had died of COVID-19. Regarding psychosocial impacts, COVID-19 was associated with strained friend relationships (eg, 34.0% [95% CI, 28.4%-40.0%] of students reported worry over losing friends), lower school engagement, and less social connectedness (eg, 62.2% [95% CI, 56.7%-67.4%] of students reported feeling less socially connected to people), although more than 60% of students also reported feeling no change or a decrease in negative emotions. Males were less likely to report perceived negative impacts, especially for negative emotions such as sadness (29.2% [95% CI, 23.3%-35.9%] of males vs 46.1% [95% CI, 43.9%-48.3%] of females reported feeling more sad) and anxiety (21.8% [95% CI, 18.2%-25.8%] of males vs 39.2% [95% CI, 34.1%-44.6%] of females reported feeling more anxious). Conclusions and Relevance: This cross-sectional study provides novel insight into the perceived experiences of reservation-area American Indian youth, a population at uniquely elevated risk of poor health status and health care access, during the COVID-19 pandemic. Although mortality and morbidity rates from COVID-19 were high on American Indian reservations, student reports of psychosocial impacts were complex and suggest many students were resilient in the face of the pandemic. These findings could be used to understand and address the challenges facing American Indian youth due to the pandemic and to guide future research that examines the factors and processes associated with the reported outcomes.

School-related Promotive Factors Related to Cannabis Use Among American Indian Adolescents.

Reservation-dwelling American Indian adolescents are at exceedingly high risk for cannabis use. Prevention initiatives to delay onset and escalation of use are needed. School engagement and student's positive experiences at school have been identified as key promotive factors against cannabis use in the general population of adolescents, but little work has examined these factors among American Indian youth. Seven school-related promotive factors were examined as predictors of past 30-day cannabis use (measured 6 months later), controlling for previous onset of cannabis use as well as a set of relevant potential confounders. Models were tested using 280 adolescents in 6th or 7th grade at the start of the study from two reservation-based schools in the US. Students were surveyed three times, with 6 months in between each survey. The average age at the start of the study was 11.99 years (SD = 0.87) and 54% of participants were female. Using a cumulative logit model to predict past 30-day use, American Indian youth who reported greater school bonding, academic aspirations, proclivity to endeavor in their studies, and interest in school at Wave 2 reported less 30-day cannabis use at Wave 3 (controlling for onset of cannabis at Wave 1 and several other control variables). No evidence of an effect of self-reported grades, perceived safety, or participation in school-related extracurricular activities was found. Given substantial deterioration of these school-related promotive factors over time, and the effect of the school-related promotive factors on subsequent cannabis use, efforts to design and test interventions to promote school engagement as a protective measure against cannabis use is warranted.

Latent Class Analysis and Predictors of Marijuana Use among Reservation-based American Indian High School Students.

American Indian (AI) youth residing on reservations report higher rates of marijuana use compared to national youth. Latent class analysis (LCA) was used to identify unique types of marijuana use among 2,884 AI high school students surveyed from 26 schools across six indigenous geographic regions. Predictors of class membership were then assessed using social, cultural, and individual measures relevant to adolescent substance use. Classes and predictors were examined separately for males and females. Four-class models fit the data best for both male and female AI students. Classes differed by sex, as did predictors. Overall, social predictors related to family and peers and the individual predictor, using marijuana to cope, were the best predictors of class membership. Based on these results, prevention and intervention efforts should provide alternative coping methods for these adolescents who often live in difficult situations, and should focus on encouraging parents to effectively monitor their adolescent children and communicate clear sanctions against marijuana use.

Be under your own influence: Effectiveness of a Culturally-Adapted drug prevention campaign targeting Reservation-Dwelling American Indian youth.

Be Under Your Own Influence (BUYOI) is a previously validated school-based intervention designed to delay adolescent substance use (SU) initiation. This study examined the effectiveness of a culturally-adapted version of BUYOI in delaying SU initiation among reservation-dwelling American Indian (AI) youth. Five reservation-based middle schools participated. Three schools were randomly assigned to receive BUYOI-AI (N = 321), and two schools served as controls (N = 176). Beginning in 7th grade, all participating students completed four assessments over the study period. Discrete time hazard models estimated the effects of BUYOI on students' risk of initiating alcohol, alcohol intoxication and marijuana before the end of 8th grade. AI students exposed to BUYOI had a lower risk of initiating alcohol use or intoxication, though sex moderated the effect on intoxication. These findings provide preliminary support for the effectiveness of a culturally-adapted version of BUYOI in delaying AI youth's first-time alcohol use and intoxication.

Opioid Misuse Among American Indian Adolescents.

Objectives. To present data for opioid misuse among US reservation-based American Indian (AI) adolescents and to compare these data with national rates from Monitoring the Future (MTF).Methods. Data were from a national sample of 33 schools participating in a substance use epidemiological survey of reservation-based AI adolescents during 2018 and 2019. Participants were 8th-, 10th-, and 12th-grade AI students (n = 1592). Measures included 12-month and 30-day use of OxyContin, Vicodin, heroin, and narcotics. We computed prevalence and compared it with MTF national prevalence.Results. Across grades, AI youths demonstrated significantly greater past 12-month and 30-day opioid use relative to a national sample. Significant absolute differences in 12-month and 30-day prevalence levels ranged from 1.6% (8th-grade heroin) to 4.7% (12th-grade narcotics) and from 1.6% (12th-grade narcotics) to 1.8% (12th-grade heroin), respectively.Conclusions. Opioid misuse prevalence levels were significantly greater for reservation-based AI adolescents relative to national prevalence levels.Public Health Implications. Findings suggest that implementation of evidence-based efforts, adapted or developed to be culturally appropriate, should be significantly increased in tribal communities, along with policies to address the unique social, economic, and health issues they face.

Development and Psychometrics of Instruments to Assess School Personnel's Bystander Action in Situations of Teen Relationship Abuse and Sexual Assault.

This article describes recently developed instruments that assess school personnel's bystander barriers and intentions in situations of teen relationship abuse, sexual assault, and sexual harassment, as well as perceptions of school readiness specific to relationship abuse, sexual assault, and sexual harassment prevention and response. Participants were 1,150 high school personnel from 25 schools in New Hampshire, Massachusetts, and Maine. Specific instruments focused on bystander intentions, bystander action, barriers to bystander action, and perceptions of school readiness. Participants were randomly divided into two groups for analysis-the exploratory sample (ES; n = 575) and the confirmatory sample (CS; n = 575). Overall, the measures demonstrated acceptable fit indices. Results suggested that most measures and subscales had adequate reliability, but a few subscales had less than ideal internal consistency, which can likely be attributed to the small number of items. More work is needed, but these measures act as a starting point by which the role of school personnel in prevention initiatives and bystander intervention can be evaluated.

Early onset of cannabis use and alcohol intoxication predicts prescription drug misuse in American Indian and non-American Indian adolescents living on or near reservations.

BACKGROUND: Prescription drug misuse (PDM) is a growing issue within the American Indian (AI) population, especially in younger populations. OBJECTIVES: This study estimates relationships between PDM and early initiation (prior to 14 yrs) of cannabis use and alcohol intoxication for a national sample of AI and non-AI adolescents attending schools on or near reservations. METHOD: Participants were 2580 students (50.2% female; 58.1% AI), ages 15-18, attending schools located on or near an AI reservation. Four models of PDM were estimated: 1) demographic variables; 2) demographics plus cannabis use initiation status; 3) demographics plus alcohol intoxication initiation status; and 4) all variables. All analyses were conducted using multilevel modeling. RESULTS: Results indicated that early onset of cannabis use and alcohol intoxication were individually significant predictors of PDM for AI and non-AI adolescents, with odds ratios (OR) of 47.00 for cannabis (p <.01) and 35.73 (p <.01) for intoxication and with no significant differences by race (AI vs. non-AI). Results also indicated a greater likelihood of PDM when a student was an early initiator of both cannabis use and intoxication than when they were one or the other. Finally, there was a significantly greater association between cannabis use and PDM (ORearlycannabis = 24.95, p <.01) than between intoxication and PDM (ORearlyintoxication = 3.98, p <.01) when both predictors were in the model. CONCLUSIONS: These findings suggest that for AI and non-AI youth who have some shared living experience, early initiation of cannabis use and alcohol intoxication are risk factors that are similarly related to PDM and that targeting early initiation for both groups of adolescents is critical in prevention of PDM.

Comparing cannabis use motive item performance between American Indian and White youth.

OBJECTIVE: There is limited research on the motives for engaging in cannabis use for American Indian (AI) youth. The purpose of this study was to explore the differences in cannabis use motives between White and AI youth. METHOD: This study used data from youth living on or near reservations who currently use cannabis and identify as White (n = 156) or AI (n = 922). Students completed a survey containing a measure of cannabis use motives that included coping, recreation, and expansion motives. Eight items, four coping and four recreational/expansion, were evaluated using Item Response Theory. Multi-group analyses were conducted to assess the differences in item functioning between White and AI youth. RESULTS: Three of the four items in the four-item coping model and four items in the recreational/enhancement model exhibited meaningful differential item functioning (DIF). Results suggest that AI youth were more likely to endorse coping reasons for use while White youth were more likely to endorse recreational/expansion reasons for use. CONCLUSIONS: This study provides preliminary evidence that AI and White youth meaningfully differ in their likelihood to endorse coping, recreational, and expansion reasons for cannabis use. These findings highlight the importance of attending to differences between AI and White youth substance use motives, especially when developing culturally competent intervention and prevention strategies.

The Role of Future Orientation and Self-determination on American Indian Adolescents' Intentions to Use Alcohol and Marijuana.

Substance use (SU) rates among American Indian (AI) adolescents have been greater than national rates for decades, with little progress made on reducing them. Reasons for this may include lack of evidence on which to base effective interventions, the uniqueness of this population, and the overall lack of attention that this population has received in reducing socioeconomic and health disparities. Moreover, there has been limited focus on understanding how positive individual characteristics may serve as protective factors for AI adolescents. Using data from 379 AI youth living on or near four northern plains reservations, the current study examines the relationship between future orientation (FO) and self-determination (SD) and intentions to use alcohol and marijuana, with negative consequences of SU for future goals and autonomy evaluated as potential mediators. SEM models were estimated for alcohol use and marijuana use intentions, with two separate models for each dependent variable-one assessing the direct and indirect effects of FO via perceived consequences for future goals and the other assessing the effects of SD via perceived consequences for autonomy. All models displayed good fit, but the pattern of significant effects varied by substance, by construct (FO vs. SD), and by gender. Findings suggested that SD, and more proximally, perceived consequences of use for autonomy, may be particularly useful promotive factors to target SU prevention in AI adolescents. Culturally congruent interventions designed to promote SD and autonomous motivations to abstain may be particularly impactful within a young AI adolescent population, as early adolescence represents a critical period of development for personal autonomy and identity.

Risk and Protective Factors of Current Opioid Use Among Youth Living on or Near American Indian Reservations: An Application of Machine Learning.

Opioid use among youth, particularly among American Indian (AI) youth, is rising, resulting in a large number of accidental overdoses and deaths. In order to develop effective prevention strategies, we need to use exploratory data analysis to identify previously unknown predictors of opioid use among youth living on or near reservations. The present study is an application of Machine Learning, a type of exploratory data analysis, to the Our Youth, Our Future epidemiological survey (N = 6482) to determine salient risk and protective factors for past 30-day opioid use. The Machine Learning algorithm identified 11 salient risk and protective factors. Importantly, highest risk was conferred for those reporting recent cocaine use, having ever tried a narcotic other than heroin, and identifying as American Indian. Protective factors included never having tried opioids other than heroin, infrequent binge drinking, having fewer friends pressuring you to use illicit drugs, initiating alcohol use at a later age, and being older. This model explained 61% of the variance in the training sample and, on average, 24% of the variance in the bootstrapped samples. Taken together, this model identifies known predictors of 30-day opioid use, for example, recent substance use, as well as unknown predictors including being AI, Snapchat use, and peer encouragement for use. Notably, recent cocaine use was a more salient predictor of recent opioid use than lifetime opioid use.

Predictors of Substance Use Latent Classes Among American Indian Youth Attending Schools On or Near Reservations.

BACKGROUND AND OBJECTIVES: Identical latent classes of substance use for 7 to 8 grade and 9 to 12 grade American Indian (AI) youth living on or near reservations suggest that patterns of substance use are established early among these youth. This study examines relationships of substance-related factors to latent class membership and whether these relationships differ by grade group. METHODS: In-school surveys were administered to 1503 7 to 8 grade and 1995 9 to 12 grade students from 46 schools on or near reservations during the 2009/2010 to 2012/2013 school years. Four-class latent class models of substance use were specified and five classes of substance-related factors (peers, substance availability, perceived harm, family, early initiation), plus grade level and gender, were evaluated as predictors. RESULTS: For 7 to 8 grade students, substance-related factors differentiated nonusers from users, while for 9 to 12 graders, these factors also differentiated types of users. Early initiation and peer factors were strongly related to class membership, while other factors were less strongly related. DISCUSSION AND CONCLUSIONS: Early initiation of alcohol or marijuana is strongly related to being in a substance-using class for AI youth. Because these youth tend to initiate use earlier that other US youth, prevention resources should be targeted to reaching them and their families before age 12. SCIENTIFIC SIGNIFICANCE: Predictors of latent classes of substance use were identified for reservation-based AI youth. While the classes were identical for 7 to 8 grade and 9 to 12 grade youth, predictors varied across grade group, which may inform how best to develop prevention efforts unique to middle and high school AI youth.

The Imperative for Research to Promote Health Equity in Indigenous Communities.

Health disparities exact a devastating toll upon Indigenous people in the USA. However, there has been scant research investment to develop strategies to address these inequities in Indigenous health. We present a case for increased health promotion, prevention, and treatment research with Indigenous populations, providing context to the recent NIH investment in the Intervention Research to Improve Native American Health (IRINAH) network. We discuss the disproportionate costs and consequences of disparities borne by Indigenous groups, the limited evidence base on effective intervention for this population, how population uniqueness often makes transfer of existing intervention models difficult, and additional challenges in creating interventions for Indigenous settings. Given the history of colonial disruption that has included genocide, forced removal from lands, damaging federal, state and local policies and practices, environmental contamination, and most recently, climate change, we conclude research that moves beyond minor transformations of existing majority population focused interventions, but instead truly respects Indigenous wisdom, knowledge, traditions, and aspirations is needed, and that investment in intervention science to address Indigenous health disparities represent a moral imperative.

Self-esteem, cultural identification, and substance use among American Indian youth.

OBJECTIVES: Determine potential mediating and moderating effects of self-esteem on the relationship between cultural identification and substance use among American Indian (AI) youth. METHODS: Anonymous surveys were administered to middle and high school AI students assessing levels of last month alcohol and marijuana use, cultural identification, and self-esteem. Structural equation modeling assessed potential mediating and moderating effects of self-esteem on the relationship between AI and white identification on alcohol and marijuana use. RESULTS: No mediating effects were found for middle school students. Among high school students, no mediating effects were found for alcohol. Among female high school students, a small mediating effect was found between AI identification and marijuana use, with AI identification protecting against use. Across all students, no moderating effects of self-esteem were found. CONCLUSIONS: The literature on cultural identification and substance use among minority youth is unclear. It was anticipated that consideration of self-esteem as a potential mediator or moderator might help clarify some of the confusion. However, no moderating effects were found and mediating effects were limited to female high school students for marijuana. Consideration should be given to assessing other measures of cultural identification and subscales of self-esteem to confirm that these findings are robust.
