Short-Term Secondary Effects of a School-Based Drug Prevention Program: Cluster-Randomized Controlled Trial of the Brazilian Version of DARE's Keepin' it REAL

Health indicators in Brazil and Spain: strategies for health promoting universities

AIMS

The study aims to identify and compare health indicators collected by national research in Spain and in Brazil that can generate action strategies for health promoting universities.

METHODS

This is an epidemiological, descriptive, cross-sectional study that uses the database of the Secretariat of Health Surveillance of the Brazilian Ministry of Health and the database of the National Statistics Institute of Spain. Based on the National Health Promotion Policy, the analyzer axis prioritizes defined themes; percentage of physical exercise, daily smokers, sedentary lifestyle, obesity and self-perception of health status were evaluated. The data were collected from 2014 to 2020.

RESULTS

In Brazil, physical exercise is the highest percentage indicator, whereas in Spain, sedentary lifestyle is the highest. Regarding the age group, Brazil presented the lowest prevalence of daily smokers in the age group from 18 to 24, with little increase in older age groups; in Spain, older age groups presented the highest rates of sedentary lifestyle and obesity. In 2020, 4.5% of Brazilians reported a negative self-perception of health and in Spain 6.6%.

CONCLUSION

The indicators 'physical exercise', 'daily smokers' and 'sedentary lifestyle' presented better results in Brazil than in Spain. Brazil presents a better perspective on health when compared with Spain, as the results showed that older ages present higher rates of sedentary lifestyle and obesity. Our study results also show that Brazilians report better self-perception in health, which can be interpreted by health promotion strategies.

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 (β = 0.103, p = .001) and kiREAL-S (β = 0.064, p = .002) compared to Control. However, only MREAL lead to less frequent use of alcohol (β = -0.001, p = .038), cigarettes (β = -0.001, p = .019), marijuana (β = -0.002, p = .030), and inhalants (β = -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.

Implementation fidelity of a Brazilian drug use prevention program and its effect among adolescents: a mixed-methods study

BACKGROUND

Based on the US DARE-kiR, a version of the Keepin' it REAL program, the Drug and Violence Resistance Educational Program (PROERD) is the most widely implemented Brazilian prevention program. It originates from the translation of the DARE-kiR, a version of the Keepin' it REAL program. Previous results suggest its inefficiency in preventing drug use among Brazilian adolescents. Since kiR fidelity can impact program outcomes, this mixed-methods study evaluates the PROERD implementation fidelity and its effects on preventing drug use among adolescents.

METHODS

Data from two cluster randomized controlled trials (cRCTs) with 4,030 students from 30 public schools in São Paulo (1,727 fifth graders and 2,303 seventh graders), assessed at two-time points, were analyzed quantitatively. After implementing each lesson during the cRCT, 19 PROERD instructors answered fidelity forms. The effect of PROERD fidelity on alcohol, cigarettes, marijuana, inhalant, and cocaine use (the last two only among seventh graders) in the six months prior to follow-up assessment was analyzed by logistic regressions for fifth grade and mixed effect models for seventh graders. For qualitative analysis, semi-structured interviews were conducted with PROERD instructors and investigated by thematic analysis.

RESULTS

Quantitative analysis showed that PROERD implementation fidelity had no impact on drug use among fifth and seventh graders. Conversely, the qualitative analysis revealed important aspects that may influence implementation fidelity and consequently program effectiveness, such as adaptations made by instructors, school infrastructure, among others, besides program application.

CONCLUSION

PROERD requires cultural adaptation to improve its implementation in Brazilian public schools.

Revisão sistemática sobre o efeito do programa escolar de prevenção ao uso de drogas Keepin’ it REAL: traduzido e implementado no Brasil pelo PROERD

Resumo O Programa Educacional de Resistência às Drogas (PROERD) é o programa escolar de prevenção mais disseminado no Brasil, seu atual currículo é baseado no programa norte-americano Keepin’it REAL (kiR). Não há na literatura evidência de efetividade do PROERD na prevenção ao uso de drogas, sendo necessários estudos complementares que auxiliem a compreensão desses achados. O objetivo do presente estudo é realizar uma síntese das evidências do efeito do currículo que deu origem ao PROERD: o kiR. Através de revisão sistemática encontrou-se 17 estudos que reportaram resultados de efeito de diferentes versões do kiR no uso de drogas e/ou violência. Com exceção do estudo brasileiro, não foram encontrados estudos que avaliassem o efeito no uso de drogas da versão aplicada por policiais (DARE-kiR), a mesma implementada pelo PROERD. Foram encontradas evidências favoráveis do kiR na prevenção ao uso de drogas para o currículo do 7º ano, que contrariam os resultados de efeito nulo do PROERD. Não foram encontradas evidências internacionais do efeito do kiR no currículo do 5º ano, assim como o estudo do PROERD. Sugere-se que revisões no currículo do 7º ano do PROERD para que ele possa refletir os resultados internacionais e que o currículo do 5º ano posso ser repensado considerando as evidências negativas internacionais.

A systematic review of the effect of the school-based drug prevention program Keepin’ it REAL: translated and implemented in Brazil by PROERD

Abstract The Drug Resistance Educational Program (PROERD) is Brazil’s most widespread school-based prevention program; its current curriculum is based on the North American Keepin’ it REAL (kiR) program. There is no evidence of the effectiveness of PROERD in preventing drug use, pointing to the need for further studies to understand these findings. The aim of the study was to synthesis the evidence of the effect of the kiR curriculum (PROERD) through a systematic review. We found 17 studies that reported the effects of different versions of kiR on drug use and/or violence. Except for the Brazilian study, no studies were found that assessed the effect on drug use of the version applied by police officers (DARE-kiR), the same one implemented by PROERD. Favorable evidence of kiR in drug use prevention was found for the 7th-grade curriculum, which contradicts the PROERD’s null-effect results. No international evidence of the effect of kiR was found in the 5th-grade curriculum, in the same line as the PROERD’s study. It is suggested that PROERD’s 7th-grade curriculum should be revised to reflect international results and that the 5th-grade curriculum should be reconsidered in light of the negative international evidence.

Social Validity in Spain of the Mantente REAL Prevention Program for Early Adolescents

Studies focusing on the relevance or impact of a program, not just on its efficacy or effectiveness, can make important contributions to prevention science. This article documents the social validity (i.e., a construct encompassing feasibility, acceptability, and utility) of a universal substance use prevention program for early adolescents in Spain. The Mantente REAL (keepin’it REAL) program was culturally adapted to the Spanish context, implemented, and evaluated in six public middle schools in two regions of Spain. Participating teachers (N = 15), students (N = 354), and research team members (N = 6) reported on the feasibility, acceptability, and utility of the program implemented with first grade secondary school students. Qualitative and quantitative data about the program, its curriculum, and the implementation process were collected through teachers’ focus groups, students’ surveys, and observation forms completed by members of the research team. Mantente REAL was perceived to be a prevention program that was feasible for implementation in Spanish middle schools, although some logistics related to school structural constraints should be addressed in future implementations. The topics and activities in the curriculum were highly accepted by teachers and students, and they reported that the program was useful in teaching resistance strategies to cope with substance use and other risky situations. The findings support the social validity of the culturally adapted Mantente REAL program for early adolescents in Spain, and highlight how feedback from stakeholders involved in the implementation can improve the dissemination of effective prevention approaches.

Applying a Pattern-Centered Approach to Assess the Effect of a School-Based Drug Use Prevention Program in Brazil: A Cluster Randomized Controlled Trial

This study evaluated the effectiveness of a drug and violence resistance educational program (Programa Educacional de Resistência às Drogas e à Violência-PROERD) on latent substance use profiles over a 9-month follow-up period. Two PROERD curricula were evaluated through a cluster randomized controlled trials with two parts that included a total of 4030 fifth-and seventh-grade students in 30 public schools in São Paulo. The intervention groups received 10 PROERD classes delivered by trained police officers, while the control group received no intervention. The primary outcome measures were drug use (any alcohol use, binge drinking, tobacco, marijuana, and inhalants) in the past 6 months, which was assessed using a pretest and a posttest 9 months later. Latent transition analysis was employed to investigate the effect of the intervention on the probabilities associated with the transition across drug use profiles. Latent drug use profiles are underlying subgroups of individuals similar to each other regarding their pattern of polysubstance use. Two different latent drug use profiles were revealed among the fifth graders (abstainers/low users and alcohol users/binge drinkers) and three drug use profiles among the seventh graders (abstainers/low users, alcohol users/binge drinkers, and polydrug users). For both, there was no evidence of the effect of PROERD on drug transition probabilities. In conclusion, the intervention was not successful in changing transitions across adolescent drug use profiles. Thus, the failure of the intervention to affect students' substance use profiles suggests that it should be reconsidered before it is implemented further in Brazilian schools.
