Parenting in 2 Worlds: Testing improved parent-adolescent communication about sexuality in Urban American Indian families.

Urban American Indian (AI) adolescents are more likely than non-Natives to have early sexual debut, teen pregnancies, sexually transmitted infections, and inadequate sexual health information. A RCT in three Arizona cities, with 585 parents of urban AI adolescents, tested whether a culturally tailored parenting intervention for urban AI families, Parenting in 2 Worlds (P2W), increased parent-adolescent communication about sexuality, compared to an informational family health intervention that was not culturally tailored. P2W produced significantly larger increases on two measures: communication about general sexual health and about sexual decision-making. The desired effects of P2W on the first measure were stronger short-term for cross-gender dyads, while for the second measure, they were stronger long-term for both mothers and fathers of adolescent sons.

Facilitating Growth Mixture Model Convergence in Preventive Interventions.

Growth mixture models (GMMs) are applied to intervention studies with repeated measures to explore heterogeneity in the intervention effect. However, traditional GMMs are known to be difficult to estimate, especially at sample sizes common in single-center interventions. Common strategies to coerce GMMs to converge involve post hoc adjustments to the model, particularly constraining covariance parameters to equality across classes. Methodological studies have shown that although convergence is improved with post hoc adjustments, they embed additional tenuous assumptions into the model that can adversely impact key aspects of the model such as number of classes extracted and the estimated growth trajectories in each class. To facilitate convergence without post hoc adjustments, this paper reviews the recent literature on covariance pattern mixture models, which approach GMMs from a marginal modeling tradition rather than the random effect modeling tradition used by traditional GMMs. We discuss how the marginal modeling tradition can avoid complexities in estimation encountered by GMMs that feature random effects, and we use data from a lifestyle intervention for increasing insulin sensitivity (a risk factor for type 2 diabetes) among 90 Latino adolescents with obesity to demonstrate our point. Specifically, GMMs featuring random effects-even with post hoc adjustments-fail to converge due to estimation errors, whereas covariance pattern mixture models following the marginal model tradition encounter no issues with estimation while maintaining the ability to answer all the research questions.

Organ fat in Latino youth at risk for type 2 diabetes.

PURPOSE: Obesity in youth increases the risk for type 2 diabetes (T2D) and elevated abdominal adipose tissue and organ fat may be particularly deleterious. The purpose of this study was to examine associations among measures of adiposity including total, visceral, and organ fat (hepatic and pancreatic) and whether these measures were independently associated with glycemia in Latino youth at risk for diabetes. METHODS: Latino adolescents (47 boys and 32 girls, 13.7 ± 1.4 years) with obesity (BMIz 2.3 ± 0.3) were assessed for total fat by DXA and visceral and organ fat by 3 T magnetic resonance imaging. Glycemic indicators included HbA1c, fasting glucose (FG), and 2-h glucose (2-HrG) following an oral glucose tolerance test. Pearson correlations and stepwise linear regression analyses controlling for age and sex were used to examine independent associations between adiposity and glycemia. RESULTS: Total fat was associated with visceral (r = 0.66, p = 0.001) and hepatic fat (r = 0.34, p < 0.01) while visceral fat was associated with hepatic (r = 0.42, p < 0.001) and pancreatic fat (r = 0.36, p < 0.001). In stepwise linear regression analysis, hepatic and pancreatic fat were significant predictors of FG, explaining 4.7% and 5.2% of the variance, respectively (total R2  = 0.14, p = 0.02). Hepatic fat was the only significant predictor of 2-HrG explaining 9.9% of the variance in the model (total R2  = 0.12, p = 0.03). No measure of adiposity was retained as a significant predictor of HbA1c. CONCLUSION: Hepatic and pancreatic fat were the only adiposity measures independently associated with glycemia but the small amount of variance explained underscores the need for additional T2D biomarkers in high risk youth.

Keepin' It REAL-Mantente REAL in Mexico: a Cluster Randomized Controlled Trial of a Culturally Adapted Substance Use Prevention Curriculum for Early Adolescents.

This study assesses the efficacy of a version of the keepin' it REAL (kiREAL) substance use prevention curriculum for middle school students that was culturally adapted for Mexico, renamed Mantente REAL (MREAL), and tested in a cluster randomized controlled trial in Mexico's three largest cities. Student participants were in 7th grade in public middle schools (N = 5523, 49% female, mean age = 11.9). A representative sample of 12 schools from each city, stratified by whether they held morning or afternoon sessions, was randomized to three conditions: culturally adapted MREAL, original kiREAL translated into Spanish, or a treatment-as-usual control group. Regular classroom teachers were trained to deliver the adapted MREAL or the kiREAL manualized curricula. Students with active parental consent completed pretest and post-test questionnaires, 7-8 months apart, at the beginning and end of the 2017-2018 academic year. We assessed the MREAL intervention, relative to kiREAL and controls, with general linear models adjusted for baseline, attrition (24%), non-normal distributions, stratification by city, and school-level clustering. Among students already using the substance more often at pretest, MREAL students had relatively more desirable outcomes, compared to kiREAL and/or to controls, in recent use of alcohol, cigarettes, "hard drugs," heavy episodic drinking, and intoxication. MREAL students reported relatively less violence victimization and perpetration of bullying and relatively more use of three of the intervention's REAL drug resistance strategies (Explain, Avoid, Leave). The adapted version of kiREAL for Mexico showed numerous desired outcomes in areas deliberately targeted in the cultural adaptation. Full protocol can be accessed through Clinical Trials.gov.

Testing a Culturally Adapted Youth Substance Use Prevention Program in a Mexican Border City: Mantente REAL.

Background: This article reports on a test of a youth substance use prevention program conducted in Nogales-Sonora, a Mexican city on the US border. Objective: The study tested the efficacy of a version of the keepin' it REAL curriculum for middle school students that was culturally adapted for Mexico and renamed Mantente REAL. Methods: Students in 7th grade classrooms in four public schools participated in the study (N = 1,418, 49% female, mean age = 11.9). Using a clustered randomized design, two schools received the intervention and two served as a treatment-as-usual control group. Regular classroom teachers were trained to deliver the twelve-lesson Mantente REAL manualized curriculum. Parents provided active consent and students gave written assent to collect pretest and posttest questionnaire data, 7 months apart, at the beginning and end of the 2017-2018 academic year. We assessed the Mantente REAL intervention with general linear models adjusted for baseline, attrition, non-linear distributions, and school-level clustering. Results: Students who participated in Mantente REAL reported relatively less frequent use of alcohol and illicit drugs other than marijuana, compared to students in control schools. Males alone reported desirable intervention effects for marijuana use. These desirable effects were especially strong among students who reported higher initial levels of involvement in risky behaviors. Among students more at risk, both females and males receiving the program reported relative reductions in the frequency of use of alcohol and illicit drugs. Conclusions: These promising results within the Mexico-US border context support a further dissemination of the intervention and additional youth prevention research in the region.

Response heterogeneity to lifestyle intervention among Latino adolescents.

OBJECTIVE: To characterize the heterogeneity in response to lifestyle intervention among Latino adolescents with obesity. METHODS: We conducted secondary data analysis of 90 Latino adolescents (age 15.4 ± 0.9 y, female 56.7%) with obesity (BMI% 98.1 ± 1.5%) that were enrolled in a 3 month lifestyle intervention and were followed for a year. Covariance pattern mixture models identified response phenotypes defined by changes in insulin sensitivity as measured using a 2 hour oral glucose tolerance test. Baseline characteristics were compared across response phenotypes using one-way ANOVA and chi-square test. RESULTS: Three distinct response phenotypes (PH1, PH2, PH3) were identified. PH1 exhibited the most robust response defined by the greatest increase in insulin sensitivity over time (ß ± SE, linear 0.52 ± 0.17, P < .001; quadratic -0.03 ± 0.01, P = .001). PH2 showed non-significant changes, while PH3 demonstrated modest short-term increases in insulin sensitivity which were not sustained over time (linear 0.08 ± 0.03, P = .002; quadratic -0.01 ± 0.002, P = .003). At baseline, PH3 (1.1 ± 0.4) was the most insulin resistant phenotype and exhibited the highest BMI% (98.5 ± 1.1%), 2 hours glucose concentrations (144.0 ± 27.5 mg/dL), and lowest beta-cell function as estimated by the oral disposition index (4.5 ± 2.8). CONCLUSION: Response to lifestyle intervention varies among Latino youth with obesity and suggests that precision approaches are warranted to meet the prevention needs of high risk youth.

Familism, Self-Esteem, and Weight-Specific Quality of Life Among Latinx Adolescents With Obesity.

OBJECTIVE: Obesity is a critical public health condition affecting Latinx adolescents and contributes to health disparities across the lifespan. Childhood and adolescent obesity is associated with reduced quality of life (QoL) and decreased self-esteem. The purpose of this study is to examine the role of cultural (e.g., familism) and psychosocial (e.g., self-esteem) factors as predictors of weight-specific QoL among Latinx adolescents with obesity. METHODS: Baseline data from 160 Latinx adolescents (ages 14-16 years) with obesity (BMI > 95th percentile for age and sex) who were recruited for a diabetes prevention intervention were used. Structural equation modeling tested the relationships between four latent constructs (familism, positive self-esteem, self-deprecation, and weight-specific QoL). RESULTS: The model tested paths from familism to positive self-esteem, self-deprecation, and weight-specific QoL, and paths from positive self-esteem and self-deprecation to weight-specific QoL. Higher familism was positively associated with positive self-esteem but not self-deprecation. In turn, positive self-esteem was positively associated with higher weight-specific QoL, whereas self-deprecation was negatively associated. Furthermore, there was an indirect effect of familism on QoL via positive self-esteem. CONCLUSIONS: These data shed light into specific cultural and psychosocial constructs that influence QoL among Latinx adolescents with obesity. This study suggests that familism and positive self-esteem can operate as protective factors associated with higher weight-specific QoL in Latinx adolescents with obesity; whereas self-deprecation may operate as a risk factor for lower weight-specific QoL.

Parenting in 2 worlds: Effects of a culturally grounded parenting intervention for urban American Indians on participant cultural engagement.

BACKGROUND: Culturally appropriate, evidence-based prevention programs are seldom available to the growing majority of American Indians (AIs) who now live in cities. Parenting in 2 Worlds (P2W), a culturally grounded parenting intervention, was created to strengthen family functioning and reduce behavioral health risks in urban AI families from diverse tribal backgrounds. OBJECTIVES: This study reports on the AI cultural engagement of the P2W participants as an outcome of the intervention. METHOD: Data came from 575 parents of AI children (ages 10-17) in a randomized controlled trial in three Arizona cities. Parents were recruited through urban Indian centers and randomized to P2W or to an informational family health curriculum, Healthy Families in 2 Worlds (HF2W). Both P2W and HF2W consisted of 10 workshops delivered weekly by AI community facilitators. Pretests and posttests measured identification and engagement with traditional AI heritage, culture and practices. Tests of the efficacy of P2W versus HF2W used baseline adjusted regression models using FIML estimation to adjust for attrition, including random effects (site, facilitator), and controlling dosage. Moderated treatment effects by pretest levels of cultural engagement were tested with mean centered interactions. RESULTS: Compared to parents in HF2W, those in P2W reported significantly larger increases in AI ethnic identity, AI spirituality, and positive mainstream cultural identification. Increases in cultural engagement were significantly larger for P2W participants who were relatively less culturally engaged at pretest. CONCLUSIONS: Culturally adapted parenting interventions like P2W that effectively build on AI cultural heritage can also promote greater AI cultural identification and involvement.

The Role of Culture of Origin on the Effectiveness of a Parents-Involved Intervention to Prevent Substance Use Among Latino Middle School Youth: Results of a Cluster Randomized Controlled Trial.

The purpose of this study was to assess the combined effectiveness of a parenting intervention, Families Preparing the New Generation (FPNG), and a youth curriculum, keepin' it REAL (kiR), on substance use prevention for middle school students in a large urban metro area of the southwest USA. The study aimed to generate usable knowledge on what works in adolescent substance use prevention and how it works best-a combined parent and youth programming or parent-only programming. A total of 532 adolescents in the 7th grade from 19 participating middle schools were randomly assigned into three intervention conditions: parent-youth (PY), parent-only (PO), and comparison (C). This article focuses on the comparison between PY and PO in order to determine which intervention strategy works best to reduce adolescent substance use including alcohol, inhalant, cigarette, and marijuana uses. A generalized estimating equation (GEE) model examined the longitudinal data. The results for alcohol use show that PO yielded better results than PY and that PY outperformed C after 20 months. Further, PO showed a decreasing trajectory in any substance use over time since the implementation of the intervention. The effect sizes based on Cohen's h indicate small effects in any substance use and alcohol use for PO condition and smaller effects for the PY condition. These findings have implications for the design of future culturally specific parenting and youth prevention interventions with Latino families.

Testing the keepin' it REAL Substance Use Prevention Curriculum Among Early Adolescents in Guatemala City.

This article describes a test in Guatemala City of Mantente REAL, a linguistically adapted version of the keepin' it REAL universal substance use prevention curriculum for early adolescents that teaches culturally grounded drug resistance, risk assessment, and decision making skills. Academic researchers collaborated with a local non-profit to recruit and randomize 12 elementary schools in Guatemala City to intervention and comparison conditions. Regular classroom teachers were trained to deliver the ten-lesson Mantente REAL (MR) manualized curriculum to sixth-grade students. Parents provided passive consent and students gave active assent for data collection, which occurred between February 2013 and September 2014. Two academic year cohorts of students participated (n = 676; 53% male; M age = 12.2). All students completed a pretest questionnaire before the curriculum lessons began in intervention schools and a posttest (87% matched) 4 months later, 1 month after the final lesson. We assessed the MR intervention with paired t tests, effect sizes (Cohen's d), and general linear models adjusted for baseline, attrition, non-linear distributions, and school-level clustering. Results indicated that MR can be an effective school-based prevention approach in Guatemala. The MR participants reported pretest-to-posttest changes in desirable directions on substance use behaviors, attitudinal antecedents of substance use, and acquisition of drug resistance skills. The comparison group generally changed in undesirable directions. In linear models, the MR participants, relative to the comparison group, reported less cigarette and marijuana use, less positive drug use expectancies, and greater use of drug resistance skills. Intervention effect sizes were between .2 and .3.

Reciprocal Effects of Alcohol Use and Violence Perpetration Among Early Adolescents in Mexico: A Gendered Analysis.

Although substance use and violent behaviors often emerge together in adolescence, and both have similar widely cited causes and negative consequences for development, it remains unclear whether and how they may be linked causally. This study of early adolescents in Mexico's three largest cities tested whether alcohol use and violence perpetration are temporally related, whether their relationship is unidirectional or reciprocal, and whether the relationship differs by gender and the type of violence. The study employed longitudinal data from seventh grade students (N = 4830; M age = 12.0, range 11-15; 49% female) in 18 public middle schools in Mexico City, Guadalajara and Monterrey. Students completed questionnaires at the beginning, middle, and end of the 2014-2015 academic year. Students' responses to a multi-dimensional violence assessment emerged in two distinct patterns: criminally violent acts, and bullying/aggression. Although males engaged in both types of violence more frequently than females at all three time points, they used alcohol more frequently than females only at the first survey, after which the gender gap disappeared. Cross-lagged multi-group path models showed that, for both males and females, more frequent alcohol use predicted subsequent increases in criminally violent behavior, and bullying/aggression predicted later increases in alcohol use. Reciprocal associations varied by gender and type of violence: Alcohol use was reciprocally linked to criminally violent behavior among males only, and reciprocally linked to bullying-aggression among females alone. The results are interpreted in the context of sharply increasing rates of violence in Mexico and changing gender norms, with implications for youth prevention programs.

THE INITIAL ASSESSMENT OF A COMMUNITY-BASED INTERVENTION WITH MEXICAN-HERITAGE PARENTS IN BOOSTING THE EFFECTS OF A SUBSTANCE USE PREVENTION INTERVENTION WITH YOUTH.

Drawing from an ecodevelopmental framework, this article examines if adding a parenting component, Families Preparing the New Generation (Familias Preparando la Nueva Generación), to an efficacious classroom-based drug abuse prevention intervention, keepin'it REAL, will boost the effects of the youth intervention in preventing substance use for middle school Mexican-heritage students. Youth attending schools in a large urban area in the Southwestern U.S. (N = 462) were randomly assigned to 1 of 3 conditions: parent and youth, youth only, or control. Using ordinary least squares regression, changes in youth substance use outcomes were examined. Results indicate that youth whose parents also participated in prevention programming exhibited significantly lower use of alcohol, cigarettes, marijuana, and inhalants compared to youth who received only keepin'it REAL. These initial effects indicate that involving parents in prevention efforts can strengthen the overall efficacy of a youth prevention intervention. This article discusses specific implications for the design of prevention interventions, policy, and future research.

Substance Use Prevention for Urban American Indian Youth: A Efficacy Trial of the Culturally Adapted Living in 2 Worlds Program.

This article describes a small efficacy trial of the Living in 2 Worlds (L2W) substance use prevention curriculum, a culturally adapted version of keepin' it REAL (kiR) redesigned for urban American Indian (AI) middle school students. Focused on strengthening resiliency and AI cultural engagement, L2W teaches drug resistance skills, decision making, and culturally grounded prevention messages. Using cluster random assignment, the research team randomized three urban middle schools with enrichment classes for AI students. AI teachers of these classes delivered the L2W curriculum in two schools; the remaining school implemented kiR, unadapted, and became the comparison group. AI students (N = 107) completed a pretest questionnaire before they received the manualized curriculum lessons, and a posttest (85% completion) 1 month after the final lesson. We assessed the adapted L2W intervention, compared to kiR, with paired t tests, baseline adjusted general linear models, and effect size estimates (Cohen's d). Differences between the L2W and kiR groups reached statistically significant thresholds for four outcomes. Youth receiving L2W, compared to kiR, reported less growth in cigarette use from pretest to posttest, less frequent use of the Leave drug resistance strategy, and less loss of connections to AI spirituality and cultural traditions. For other substance use behaviors and antecedents, the direction of the non-significant effects in small sample tests was toward more positive outcomes in L2W and small to medium effect sizes. Results suggest that evidence-based substance use prevention programs that are culturally adapted for urban AI adolescents, like L2W, can be a foundation for prevention approaches to help delay initiation and slow increases in substance use. In addition to study limitations, we discuss implementation challenges in delivering school-based interventions for urban AI populations.

Changing Latino Adolescents' Substance Use Norms and Behaviors: the Effects of Synchronized Youth and Parent Drug Use Prevention Interventions.

While parent and youth substance use prevention interventions have shown beneficial effects on preadolescents, many programs have typically targeted US born European American and African American families while overlooking the unique factors that characterize recent immigrant Latino families. This article presents the results on youth substance use when adding a culturally grounded parenting component, Familias Preparando la Nueva Generación (FPNG), to the existing and already proven efficacious classroom-based drug abuse prevention intervention, keepin'it REAL (kiR). Data come from youth (N = 267) participating in the randomized control trial of the interventions who were surveyed at baseline (beginning at 7th grade) and 18 months later (end of 8th grade). Using multivariate linear regression path analyses, results indicate when FPNG and kiR are combined, youth had significantly lowered alcohol and cigarettes use at the end of 8th grade, mediated through anti-drug norms, when compared with youth who only participated in kiR without parental participation in FPNG. These findings indicate that adolescent normative beliefs and related behaviors can be changed through synchronized culturally grounded parent and youth interventions and together can play an important role in reducing adolescent substance use.

Parenting in 2 Worlds: Effects of a Culturally Adapted Intervention for Urban American Indians on Parenting Skills and Family Functioning.

Parenting in 2 Worlds (P2W) is a culturally grounded parenting intervention that addresses the distinctive social and cultural worlds of urban American Indian (AI) families. P2W was culturally adapted through community-based participatory research in three urban AI communities with diverse tribal backgrounds. This paper reports the immediate outcomes of P2W in a randomized controlled trial, utilizing data from 575 parents of AI children (ages 10-17). Parents were assigned to P2W or to the comparison group, an informational family health curriculum, Healthy Families in 2 Worlds (HF2W). Both the P2W and HF2W curricula consisted of 10 workshops delivered weekly by AI community facilitators. Pretests were administered at the first workshop and a post-test at the last workshop. Tests of the efficacy of P2W versus HF2W on parenting skills and family functioning were analyzed with pairwise t tests, within intervention type, and by baseline adjusted path models using FIML estimation in Mplus. Intervention effect sizes were estimated with Cohen's d. Participants in P2W reported significant improvements in parental agency, parenting practices, supervision and family cohesion, and decreases in discipline problems and parent-child conflict. Compared to HF2W, P2W participants reported significantly larger increases in parental self-agency and positive parenting practices, and fewer child discipline problems. Most of these desired program effects for P2W approached medium size. Culturally adapted parenting interventions like P2W can effectively strengthen parenting practices and family functioning among urban AI families and help address their widespread need for targeted, culturally grounded programs.

Substance Use Profiles of Urban American Indian Adolescents: A Latent Class Analysis.

UNLABELLED: A growing majority of American Indian adolescents now live in cities and are at high risk of early and problematic substance use and its negative health effects. OBJECTIVE: This study used latent class analysis to empirically derive heterogeneous patterns of substance use among urban American Indian adolescents, examined demographic correlates of the resulting latent classes, and tested for differences among the latent classes in other risk behavior and prosocial outcomes. METHOD: The study employed a representative sample of 8th, 10th, and 12th grade American Indian adolescents (n = 2,407) in public or charter schools in metropolitan areas of Arizona in 2012. Latent class analysis examined eight types of last 30 day substance use. RESULTS: Four latent classes emerged: a large group of "nonusers" (69%); a substantial minority using alcohol, tobacco, and/or marijuana [ATM] (17%); a smaller group of polysubstance users consuming, alcohol, tobacco, marijuana, other illicit drugs, and prescription or OTC drugs in combination (6%); and a "not alcohol" group reporting combinations of tobacco, marijuana, and prescription drug use, but rarely alcohol use (4%). The latent classes varied by age and grade level, but not by other demographic characteristics, and aligned in highly consistent patterns on other non-substance use outcomes. Polysubstance users reported the most problematic and nonusers the least problematic outcomes, with ATM and "not alcohol" users in the middle. CONCLUSIONS: Urban AI adolescent substance use occurs in three somewhat distinctive patterns of combinations of recent alcohol and drug consumption, covarying in systematic ways with other problematic risk behaviors and attitudes.

Bullying among Urban Mexican-heritage Youth: Exploring Risk for Substance Use by Status as a Bully, Victim, and Bully-Victim.

Little is known about adolescent bullying behavior and its relationship to substance use in ethnic minority populations. In a sample of youth of Mexican heritage, the current study aimed to examine the prevalence of bullying behavior subtypes and its co-occurrence with recent alcohol, cigarette, and inhalant use. Data come from a school-based substance use prevention study in the Southwestern U.S. (n=809). We explored the prevalence of bullying behavior by status among youth classified as bullies, victims, bully-victims, and rarely-involved bully-victims in an urban context. We also investigated risk of past 30-day use of alcohol, cigarettes, and inhalants by bullying behavior status. Compared to non-involved youth, rarely-involved bully-victims were more likely to use alcohol, bullies were more likely to engage in alcohol and cigarette use, and bully-victims were more likely to use alcohol, cigarettes, and inhalants. In contrast, victims were not significantly at risk of substance use compared to non-involved youth. Chronic bullies and bully-victims are particularly at risk for substance use, with chronic bully-victims reflecting the greatest risk of using multiple substances. Prevention and early intervention programs aimed to reduce bullying can also work to decrease other risky behaviors, such as substance use, and should attend to the growing ethnic diversity among youth.

The Relationship Between Peer, Parent, and Grandparent Norms and Intentions to Use Substances for Urban American Indian Youth.

Peer, parent, and grandparent norms may be a protective factor for American Indian (AI) youth intentions to use substances, but little research has explored these influences on urban AI youth. Using OLS regression, a secondary data analysis examined the relationship between peer, parent and grandparent substance use norms, and intentions to use substances (N = 148). Findings indicated that grandparent and peer norms were the strongest predictors of intentions to use substances. Implications of these results include the need for concerted, culturally focused efforts that address AI youth substance use by targeting AI peer and family networks.

Parenting in 2 Worlds: pilot results from a culturally adapted parenting program for urban American Indians.

This study reports the implementation and feasibility of a culturally adapted parenting curriculum, Parenting in 2 Worlds (P2W), which we designed specifically for urban American Indian families by means of community-based participatory research and then pilot tested in three Arizona cities. Data come from matched pre- and post-test surveys completed in 2012 by 75 American Indian parents of adolescents aged 10-17 who participated in the pilot version of P2W. P2W is a 10-workshop program administered twice a week for 5 weeks by trained American Indian community facilitators. Parents completed pre-test surveys during Workshop 1 and post-test surveys 5 weeks later during Workshop 10. Paired t tests assessed changes in parenting outcomes, cultural identity, and child anti-social behavior. Changes from pre- to post-test demonstrated statistically significant improvements in several parenting outcomes (discipline, involvement, self-agency, and supervision), a strengthened sense of ethnic and cultural identity and Native spirituality, and a decrease in the child's anti-social behavior. These results, which show significant preliminary improvements in parenting skills and family functioning, suggest the feasibility of implementing a culturally grounded parenting intervention for urban American Indian parents.

Short-term effects on substance use of the keepin' it real pilot prevention program: linguistically adapted for youth in Jalisco, Mexico.

This article presents the short-term effects of a pilot study of keepin'it REAL (Manténte REAL) conducted in central Mexico by a binational team of investigators. This middle school-based model program for preventing substance use was adapted for Mexico linguistically but not culturally. Two Guadalajara public middle schools were recruited and randomly assigned to either implement the prevention program or serve as a control site. The program was implemented in the treatment site by the students' regular teachers, who were trained by the research team. Seventh graders in ten classrooms in the treatment and control schools (N = 432) completed a pretest and posttest survey in Spanish similar to the survey utilized in the original efficacy trial of keepin'it REAL in the US. T-tests and OLS regressions were conducted to determine the effects of the intervention on substance use outcomes. Differences between treatment and control groups in frequency of use of alcohol and tobacco, the two substances of choice in this sample, were significant and in the desired direction. Differences in amount of use were also in the preferred direction but were not significant for alcohol and only marginally significant for tobacco. When the sample was split by gender, statistically significant treatment effects remained for females but were not observed among males. Effects of the linguistically adapted version of keepin'it REAL appears to be driven by the change in female use; however, the difference in male and female outcomes was not statistically significant. Implications for cultural adaptation and prevention in Mexico are discussed from a communication competency perspective. The promising results of the pilot study suggest that the linguistic adaptation was effective, but that a comprehensive cultural adaptation of keepin'it REAL in partnership with Mexican investigators and communities may be warranted.
