Study protocol for a group randomized controlled trial of a classroom-based intervention aimed at preventing early risk factors for drug abuse: integrating effectiveness and implementation research

<p>Abstract</p> <p>Background</p> <p>While a number of preventive interventions delivered within schools have shown both short-term and long-term impact in epidemiologically based randomized field trials, programs are not often sustained with high-quality implementation over time. This study was designed to support two purposes. The first purpose was to test the effectiveness of a universal classroom-based intervention, the Whole Day First Grade Program (WD), aimed at two early antecedents to drug abuse and other problem behaviors, namely, aggressive, disruptive behavior and poor academic achievement. The second purpose--the focus of this paper--was to examine the utility of a multilevel structure to support high levels of implementation during the effectiveness trial, to sustain WD practices across additional years, and to train additional teachers in WD practices.</p> <p>Methods</p> <p>The WD intervention integrated three components, each previously tested separately: classroom behavior management; instruction, specifically reading; and family-classroom partnerships around behavior and learning. Teachers and students in 12 schools were randomly assigned to receive either the WD intervention or the standard first-grade program of the school system (SC). Three consecutive cohorts of first graders were randomized within schools to WD or SC classrooms and followed through the end of third grade to test the effectiveness of the WD intervention. Teacher practices were assessed over three years to examine the utility of the multilevel structure to support sustainability and scaling-up.</p> <p>Discussion</p> <p>The design employed in this trial appears to have considerable utility to provide data on WD effectiveness and to inform the field with regard to structures required to move evidence-based programs into practice.</p> <p>Trial Registration</p> <p><b>Clinical Trials Registration Number</b>: NCT00257088</p

Effects of a parental program for preventing underage drinking - The NGO program strong and clear

<p>Abstract</p> <p>Background</p> <p>The present study is an evaluation of a 3-year parental program aiming to prevent underage drinking. The intervention was implemented by a non-governmental organization and targeted parents with children aged 13-16 years old and included recurrent activities during the entire period of secondary school. The program consisted of four different types of group and self-administered activities: parent meetings, family dialogues, friend meetings, and family meetings.</p> <p>Methods</p> <p>A quasi-experimental design was used following parents and children with questionnaires during the three years of secondary school. The analytic sample consisted of 509 dyads of parents and children. Measures of parental attitudes and behaviour concerning underage drinking and adolescents' lifetime alcohol consumption and drunkenness were used. Three socio-demographic factors were included: parental education, school, and gender of the child. A Latent Growth Modelling (LGM) approach was used to examine changes in parental behaviour regarding youth drinking and in young people's drinking behaviour. To test for the pre-post test differences in parental attitudes repeated measures ANOVA were used.</p> <p>Results</p> <p>The results showed that parents in the program maintained their restrictive attitude toward underage drinking to a higher degree than non-participating parents. Adolescents of participants were on average one year older than adolescents with non-participating parents when they made their alcohol debut. They were also less likely to have ever been drunk in school year 9.</p> <p>Conclusion</p> <p>The results of the study suggested that Strong and Clear contributed to maintaining parents' restrictive attitude toward underage drinking during secondary school, postponing alcohol debut among the adolescents, and significantly reducing their drunkenness.</p

Evidence-based Kernels: Fundamental Units of Behavioral Influence

This paper describes evidence-based kernels, fundamental units of behavioral influence that appear to underlie effective prevention and treatment for children, adults, and families. A kernel is a behavior–influence procedure shown through experimental analysis to affect a specific behavior and that is indivisible in the sense that removing any of its components would render it inert. Existing evidence shows that a variety of kernels can influence behavior in context, and some evidence suggests that frequent use or sufficient use of some kernels may produce longer lasting behavioral shifts. The analysis of kernels could contribute to an empirically based theory of behavioral influence, augment existing prevention or treatment efforts, facilitate the dissemination of effective prevention and treatment practices, clarify the active ingredients in existing interventions, and contribute to efficiently developing interventions that are more effective. Kernels involve one or more of the following mechanisms of behavior influence: reinforcement, altering antecedents, changing verbal relational responding, or changing physiological states directly. The paper describes 52 of these kernels, and details practical, theoretical, and research implications, including calling for a national database of kernels that influence human behavior

Respecting alcohol, respecting the water: Young adult perspectives on how to reduce alcohol‐influenced drownings in Australia

Issue addressed: Alcohol-influenced drowning among young Australians (aged 18-24 years) is a prominent health concern. However, effectiveness of targeted prevention campaigns for this age group is unknown, as this information is not typically published in peer-reviewed or easily accessed grey literature. Accordingly, future campaigns cannot build on prior efforts to address this health problem. Methods: Semi-structured interviews ascertained young Australian adults’ perspectives on preventing alcohol consumption in aquatic settings, and their awareness of appropriate safety strategies and Australian national and state drowning prevention campaigns. Discussions were transcribed verbatim and thematically analysed using an interpretative phenomenological approach. Results: Twenty-three individuals (mean age 20.65 years) participated in an interview. Participants had poor understanding of alcohol-focused drowning prevention campaigns and used logos and names to decipher key campaign messages. Education was recommended as the preferred method for prevention, and participants suggested preferences for delivery (eg social media, in schools, humour and shock tactics). The safety strategies discussed appeared to be transferred from strategies used in other contexts, rather than related to the specific risks of aquatic scenarios. Conclusions: Drowning prevention practitioners should ensure transparency and clarity of their campaign names and logos to enhance understanding of the messages. Practitioners should also consider using audience analysis during campaign design, delivery and evaluation, alongside best practice recommendations from literature, to enhance campaign suitability and effectiveness. So what?: Water safety practitioners and policy makers should acknowledge these findings when developing campaigns which address young adults’ lack of awareness of safe aquatic behaviours to encourage a sustained behaviour change. © 2020 Australian Health Promotion Association
