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.

The Impact of Major Earthquakes on Students' Emotional Distress and Internalizing Symptoms, Externalizing Behaviors, and Coping During the Implementation of keepin' it REAL-Mexico.

This article reports on effects of two earthquakes in Mexico on adolescents attending middle school. The earthquakes struck in close succession during the implementation of a school-based prevention program, providing an opportunity to assess emotional distress due to the earthquakes and whether the life skills taught in the program affected how students coped with the natural disaster. The objectives were to (1) evaluate the earthquakes' impact on students' distress; (2) assess if distress is associated with internalizing symptomology and externalizing behaviors; and (3) investigate if students receiving the original and adapted versions of the intervention coped better with the events. A Mexico-US research team culturally adapted keepin' it REAL to address connections between substance use among early adolescents in Mexico and exposure to violence. A random sample of public middle schools from three cities (Mexico City, Guadalajara, and Monterrey), stratified by whether they held morning or afternoon sessions, was selected. A total of 5522 7th grade students from 36 schools participated in the study. Students answered pretest and posttest questionnaires; the latter assessed earthquake-related distress and coping strategies. Earthquake-related distress was associated with all measures of undesired internalizing symptomology and externalizing behaviors. Compared to controls, students in the adapted intervention reported less aggressive and rule-breaking externalizing behavior and less violence perpetration. However, these intervention effects were not moderated by the level of earthquake-related distress, and they were not mediated by positive or negative coping. The findings have implications for prevention intervention research and policy as natural and human-made disasters occur more often.

The Feasibility, Acceptability, and Utility of Mantente REAL: the Culturally Adapted Version of keepin' it REAL for Mexico.

A binational team of investigators culturally adapted, implemented, and tested the efficacy in Mexico of keepin' it REAL, a US-designed prevention intervention for youth. This article reports on the social validity of the adapted intervention by assessing its feasibility, acceptability, and utility, as perceived by participating middle school students, teachers/implementers, and school administrators. Middle schools (N = 36) were randomly assigned to (1) the culturally adapted version for Mexico (Mantente REAL), (2) the original intervention from the USA (keepin' it REAL) translated into Spanish, or (3) a control condition (treatment as usual). Adult and child feedback about the adapted and original versions of the intervention indicate that both are feasible to implement in the Mexican context. Implementation fidelity was equally high for both versions of the manualized intervention. Students, however, were more satisfied with the culturally adapted version than with the non-adapted version. They reported gaining more knowledge, finding it more acceptable, applicable, and authentic, and they reported discussing the program with their family and friends more often. The findings support the feasibility of engaging classroom teachers to implement manualized prevention programs in Mexico. These findings also advance prevention science by documenting the importance of cultural adaptation as a means to increase students' identification with and acceptability of efficacious school-based interventions. The article discusses the practice, policy, and future prevention research implications of the findings for Mexico and their potential generalizability to other middle- and lower-income countries.

Longitudinal Associations between Parental Support and Parental Knowledge on Behavioral and Emotional Problems in Adolescents.

When testing longitudinal effects of parenting practices on adolescent adjustment, an integrated consideration of externalizing and internalizing behaviors is a gap in research. This study analyzed how parental support and parental knowledge directly and indirectly influence both antisocial behavior and emotional problems. The sample had 642 adolescents aged 12-15 (mean age = 12.49; 45.4% females) from Spain, who participated in a three-year long study. The results showed longitudinal bidirectional associations between parental support and parental knowledge. Only parental knowledge, however, directly predicted antisocial behavior and emotional problems. Parental support had an indirect effect on outcomes through the mediating effect of parental knowledge. This study has practical implications by indicating that increasing parental knowledge should be the target of educational-prevention programs.

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.

Variations in risk and promotive factors on substance use among urban American Indian youth.

Although roughly 70% of the American Indian and Alaska Native (AI) population live in urban areas, research is scarce regarding this population. As a consequence, there is limited understanding about the salient socioenvironmental factors that aid in preventing substance use among urban AI communities. This study utilized a statewide, cross-sectional, school-based survey of urban AI adolescents (N = 2,375) to (a) examine the associations between substance use and risk and promotive factors within the family and peer group, and (b) explore how these associations vary by subgroups (gender, racial/ethnic background, and grade level). Results suggest that risk factors-familial substance use and antisocial peer affiliation-were associated with higher alcohol, cigarette, and marijuana use. However, these findings varied by subgroup. For males, involvement with antisocial peers was associated with greater marijuana use. Involvement with antisocial peers was also positively associated with alcohol and marijuana use for multiracial/multiethnic AI adolescents and those adolescents in 10th and 12th grades. The promotive factors-supportive family environment and prosocial peer affiliation-were not universally associated with lowered substance use by subgroup. This study advances understandings of the risk and promotive factors important in reducing and preventing substance use among urban AI adolescents. Experiencing familial substance use and affiliating with antisocial peers were the salient factors associated with increased substance use, particularly for urban AI adolescents who are older, male, and with multiracial/multiethnic AI backgrounds.

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.

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.

Traditional gender roles and substance-use behaviors, attitudes, exposure, and resistance among early adolescents in large cities of Mexico.

This study investigated the associations between traditional gender roles (TGRs) and substance use among early adolescents in Mexico's largest cities. The sample of seventh grade students (n = 4,932) attended 26 public schools in Mexico City, Guadalajara, or Monterrey in 2014. Outcomes included recent alcohol, binge drinking, cigarette and marijuana use, and lifetime poly-substance use; substance-use intentions, norms, attitudes, and expectancies; and substance-use exposure (peer use, offers) and resistance (refusal confidence, refusal skills, and decision-making skills). A TGR scale assessed endorsement of a polarized gender division of family labor and power. As hypothesized, among males, TGRs were consistently associated with poorer outcomes, and this association was usually stronger for males than for females. In contrast, among females there was no evidence that TGRs were associated with desirable outcomes. Contrary to expectations, TGRs predicted poorer outcomes for both females and males, and to equivalent degrees, for binge drinking, cigarette use, positive substance-use expectancies, and friends' approval of substance use, and they predicted poorer outcomes for females but not for males on parental disapproval of substance use and drug-resistance skills. Interpretations highlight the persisting aspects of TGRs in the family and conflicting messages for females as Mexico undergoes changes in its gender order.

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.

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.

A latent class analysis of urban American Indian youth identities.

OBJECTIVE: This study examined sources of indigenous identity among urban American Indian youth that map the three theoretical dimensions of a model advanced by Markstrom: identification (tribal and ethnic heritage), connection (through family and reservation ties), and involvement in traditional culture and spirituality. METHOD: Data came from self-administered questionnaires completed by 208 urban American Indian students from five middle schools in a large metropolitan area in the Southwest. RESULTS: Descriptive statistics showed most youth were connected to multiple indicators on all three dimensions of indigenous identity: native parental heritage, native best friends, past and current reservation connections, involvement with cultural practices, tribal language and spirituality, and alignment with native and mainstream cultural orientations. A latent class analysis identified five classes. There were two larger groups, one with strong native heritage and the highest levels of enculturation, and another that was more bicultural in orientation. The remaining three groups were smaller and about equal in size: a highly acculturated group with mixed parental ethnic heritage, those who had strong native heritage but were culturally disengaged, and a group with some mixed ethnic heritage that was low on indicators of enculturation. Evidence for the validity of the latent classes came from significant variations across the classes in scores on an American Indian ethnic identity (modified Phinney) scale, the students' open-ended descriptions of the main sources of their indigenous identities, and the better academic grades of classes that were more culturally engaged. CONCLUSIONS: Despite the challenges of maintaining cultural identities in the urban environment, most youth in this sample expressed a strong sense of indigenous identity, claimed personal and parental tribal heritage, remained connected to reservation communities, and actively engaged in Native cultural and spiritual life.

Long-term effects of the keepin' it REAL model program in Mexico: substance use trajectories of Guadalajara middle school students.

In the face of rising rates of substance use among Mexican youth and rapidly narrowing gender differences in use, substance use prevention is an increasingly urgent priority for Mexico. Prevention interventions have been implemented in Mexico but few have been rigorously evaluated for effectiveness. This article presents the long term effects of a Mexico-based pilot study to test the feasibility of a linguistically specific (Mexican Spanish) adapted version of keepin' it REAL, a school-based substance abuse prevention model program. University affiliated researchers from Mexico and the US collaborated on the study design, program implementation, data collection, and analysis. Students and their teachers from two middle schools (secundarias) in Guadalajara participated in this field trial of Mantente REAL (translated to Spanish). The schools were randomly assigned to treatment and control conditions. The sample of 431 students reported last 30 day substance use at three times (one pretest and two posttests). Changes in substance use behaviors over time were examined using growth curve models. Long term desired intervention effects were found for alcohol and marijuana use but not for cigarettes. The intervention effects were greater for girls than for boys in slowing the typical developmental increase over time in alcohol use. Marijuana effects were based on small numbers of users and indicate a need for larger scale studies. These findings suggest that keepin' it REAL is a promising foundation for cultural program adaptation efforts to create efficacious school-based universal prevention interventions for middle school students in Mexico.

Exposure to neighborhood poverty from adolescence through emerging adulthood and sleep duration in US adults.

Does exposure to neighborhood poverty from adolescence to early adulthood have differential influence on sleep duration across racial/ethnic groups? We used data from the National Longitudinal Study of Adolescent to Adult Health that consisted of 6756 Non-Hispanic (NH) White respondents, 2471 NH Black respondents, and 2000 Hispanic respondents and multinomial logistic models to predict respondent reported sleep duration based on exposure to neighborhood poverty during adolescence and adulthood. Results indicated that neighborhood poverty exposure was related to short sleep duration among NH White respondents only. We discuss these results in relation to coping, resilience, and White psychology.

Urban Violence, Migration and Alcohol, Tobacco, and Marijuana Use among Transnational Students in Northern Mexico.

This article reports on the findings of a study of the relationship between transnational experiences in the United States (US) and the use of alcohol, tobacco, and marijuana among 7th grade students (n = 1418). The study was guided by a cross-national framework for research on immigrant health and assessed the accumulation of risk factors for transnational adolescents. Data came from a survey conducted in 2017 in Nogales, Mexico. In this study, the last 30-day prevalence of use of alcohol, tobacco, and marijuana among students was 21.7%, 8.3%, and 2.4%, respectively. Most students were born in Nogales (69.6%), while 10.5% were born in the US, 7.5% attended school in the US, and 3.6% engaged in health-related risk behaviors while living in or visiting the US. Students with transnational experiences, such as attending school in the US, reported the highest 30-day prevalence of tobacco (13.3%) and marijuana (9.5%) use. After adjusting for family, school, access to substances and neighborhood violence variables, students who engaged in health-related risk behavior in the US had significantly increased odds of alcohol and marijuana use while later attending school in Mexico. The article discusses the findings from a prevention science perspective and provides implications for policy, practice, and future research on the Mexico-US border region.

Keepin' It REAL-Mantente REAL in Mexico: Longitudinal Examination of Youth Drug Resistance Strategies and Substance Use Among Early Adolescents.

PURPOSE: This study examined if culturally and linguistically adapted versions of a US-developed adolescent substance use prevention intervention, keepin' it REAL (kiREAL), for Mexico increases the use of drug resistance strategies and if increased use of resistance strategies subsequently leads to a reduction in the frequency of substance use (i.e., alcohol, cigarette, marijuana, and inhalants). METHODS: Students (N = 5,522, 49% female, age range = 11-17) in 36 middle schools across three cities in Mexico were randomized into three conditions: (1) Mantente REAL (MREAL), the culturally adapted version, (2) kiREAL-S, the linguistically adapted version, and (3) Control. Using survey data collected at four time points, random intercept cross-lagged path analyses tested the direct and indirect effects of MREAL and kiREAL-S compared to Control. RESULTS: At time 2, the number of drug resistance strategies used by students increased in both MREAL (ß = 0.103, p = .001) and kiREAL-S (ß = 0.064, p = .002) compared to Control. However, only MREAL lead to less frequent use of alcohol (ß = -0.001, p = .038), cigarettes (ß = -0.001, p = .019), marijuana (ß = -0.002, p = .030), and inhalants (ß = -0.001, p = .021) at time 4, mediated through increased use of drug resistance strategies. DISCUSSION: This study provides evidence that MREAL and kiREAL-S are successful in spurring use of the drug resistance strategies that are the core component of the intervention. Only MREAL achieved long-term effects on substance use behaviors, the ultimate objective of these interventions. These findings provide support for the value and importance of rigorous cultural adaptation of efficacious prevention programs as a necessary condition for enhancing prevention benefits for participating youth.

A Pilot Study of an Evidence-Based Prevention Intervention (keepin' it REAL) for Early Adolescents in Kenyan Schools.

CONCLUSIONS: Although larger trials with a more representative sample of schools are needed, the study suggests the potential for kiR as an effective approach for substance use prevention in Kenya. METHOD: A convenience sample of primary schools in metropolitan Nairobi was randomized into an intervention or control group. Teachers in intervention schools were trained to deliver the kiR curriculum with fidelity. Students in seventh and eighth grades in the intervention and control schools (N = 533) completed pretest and posttest questionnaires assessing substance use behaviors, attitudes, and drug resistance strategies. OBJECTIVE: Although many primary school students in Kenya report use of alcohol and other drugs, evidence-based prevention interventions for schools are generally unavailable. Globally, there are growing opportunities to conduct research that assesses whether efficacious interventions from elsewhere can be adopted for new settings and populations. This small pilot study implemented and evaluated a linguistically adapted version of the school-based keepin' it REAL (kiR) universal substance use prevention program from the United States in Kenyan primary schools to assess its effectiveness and estimate potential effect sizes. RESULTS: Relative to the control group, kiR students reported several desired changes in behaviors and attitudes: less recent alcohol use and heavy (binge) alcohol drinking, and continuing or increased adherence to certain anti-drug norms. There was partial evidence that kiR helped students rely less on conflictual drug resistance strategies, such as reacting to substance offers angrily or with violence. Effect sizes for these outcomes compare favorably to those obtained in other school-based prevention interventions.
