Demonstrating the efficacy and effectiveness of prevention programmes in rigorous randomised trials is only the beginning of a process that may lead to better public health outcomes. Although a growing number of programmes have been shown to be effective at reducing drug use and delinquency among young people under carefully controlled conditions, we are now faced with a new set of obstacles. First, these evidence‐based programmes are still under‐utilised compared to prevention strategies with no empirical support. Second, when effective programmes are used the evidence suggests they are not being implemented with quality and fidelity. Third, effective programmes are often initiated with short‐term grant funding, creating a challenge for sustainability beyond seed funding. We discuss each of these challenges, and present lessons learned from a large‐scale dissemination effort involving over 140 evidence‐based programme replications in one state in the US.

This paper seeks to discuss advances in the prevention of crime and anti‐social behaviours that have occurred in the USA in the last decade.

The paper outlines significant achievements in the identification of risk and protective factors related to anti‐social behaviours, the design and evaluation of preventive interventions and strategies intended to increase the successful and widespread implementation of these practices. The Evidence2Success model is described as an example of how scientific advances can be utilised by communities to improve youth outcomes at little added cost to taxpayers.

In a very short time span, much progress has been made in prevention sciences. Spurred in part by federal initiatives and funding opportunities, increasing numbers of preventive interventions have been developed and demonstrated as effective, and methods for disseminating these practices show promise.

These successes can be utilised by other countries to advance prevention science internationally.

To be effective, evidence‐based programs should be delivered as prescribed. This suggests that adaptations that deviate from intervention goals may limit a program's effectiveness. This study aims to examine the impact that number and quality of adaptations have on substance use outcomes.

The authors examined 306 video recordings of teachers delivering “All Stars”, a middle school drug prevention program. Multiple observers coded each recording, noting the number and type of adaptation each teacher made. Each adaptation was given a valence rating. Adaptations that were deleterious to program goals received negative valence ratings; positive ratings were given for adaptations that were likely to facilitate achievement of program goals; neutral ratings were given to adaptations that were expected to have neither a positive nor negative impact on program goals.

All teachers made adaptations. Teachers were consistent across time in the types of adaptations they made, suggesting each teacher has a personalized style of adapting. Those who made few adaptations, and whose average adaptation was rated as being positive had a higher percentage of students who remained non‐drug users. In contrast, teachers who made many adaptations, whether their average valence rating was positive, neutral or negative, failed to have as many students remain non‐drug users. Measures of fidelity, including quality of delivery and teacher understanding, were related to valence of adaptations, with better performance related to making positive adaptations.

Through training and supervision, teachers should be guided and encouraged to follow programs directions, making few adaptations and ensuring that adaptations that are made advance the goals of intervention. Programs should define acceptable and unacceptable ways they may be adapted.

This study provides significant evidence about the challenges that face disseminated evidence‐based programs.

The importance of community-based organizations to support relief works in the aftermath of disasters is widely recognized as indispensable in providing quickly the needed help for affected populations (Bajek, Matsuda, & Okada, 2008; Nagasaka, 2008; Norris, Stevens, Pfefferbaum, Wyche, & Pfefferbaum, 2008; Shaw & Goda, 2004; Suzuki, 2006). Although communities’ involvement in rescue operations is essential, their role in rehabilitation and future disaster preparedness activities is equally important in the process of forming a disaster-resilient society (Nagasaka, 2008). Furthermore, the level of interaction between local authorities and communities within different phases (preparedness, relief, and rehabilitation) of the disaster management cycle requires attention to effectively implement community-based disaster risk reduction (CBDRR).

Engagement is a critical metric to the effectiveness of online health messages. This paper explores how people engage in youth-generated prevention messages in social media.

The data sample consisted of engagement measures of 82 youth-generated messages hosted in a social media channel and a follow-up survey on content creators' motivation for promoting their messages and their dissemination strategies. A comparative analysis of engagement metrics along with qualitative analysis of the message types was performed.

Two types of messages were considered: stop messages and prevent messages. Our analyses found that people interacted with stop messages on social media more frequently than prevent messages. On analyzing the youth's motivation and promotion strategies, no significant difference was observed between stop message creators and prevent message creators.

This work has implications for programs promoting prevention and health information in social media.

This is the first study in social media-based prevention programs the authors are aware of that differentiated between the strategies of youth-produced prevention messages.

An alcohol prevention programme, consisting of the implementation of an organisational alcohol policy and skills development training for managers, was delivered in Swedish workplaces. Previous findings revealed challenges in policy implementation because of the lack of dissemination amongst managers. This study aims to describe perceived dissemination barriers of the organisational alcohol policy by managers.

A cross-sectional survey (n = 193 managers) was performed to identify common dissemination barriers in the workplace and complementary case illustrations derived from semi-structured interviews (n = 18 managers) were used to understand the dissemination barriers of the organisational alcohol policy. Frequency distributions were presented to describe common perceived barriers.

Sixty-five per cent of managers reported that their workplace had not changed their approach to addressing alcohol-related issues compared to their usual practice before programme delivery. Various organisational factors, such as deprioritisation of programme dissemination, lack of communication and inadequate strategies were some of the common barriers perceived by managers. Moreover, managers reported uncertainties regarding any changes concerning the workplace’s approach for addressing alcohol-related issues. Increased efforts in disseminating the organisational alcohol policy can reduce uncertainties among managers.

A thorough process evaluation to understand processes in programme delivery and implementation is necessary to ensure the uptake of the intervention.

This study highlighted the complexity of disseminating an alcohol policy in a dynamic setting, such as the workplace, and provided the importance of addressing organisational obstacles.

The aims of this study were to determine (1) the degree to which an evidence‐based intervention (EBI) delivered outside the context of a research trial remained faithful to the content and design of the programme as intended and as reported in experimental trials of the same programme, and (2) whether implementation quality affected programme outcomes. We report results of an observational study of 11 sites involved in the statewide dissemination of a popular family‐focused prevention programme, the Strengthening Families Programme for Parents and Youth 10‐14. We found numerous differences between the community‐based implementations we observed and researcher‐driven implementations of the same programme, but variability in programme delivery and adherence to content were unrelated to programme outcomes. We conclude that short‐term outcomes of well‐designed EBIs delivered by well‐trained facilitators may be robust to minor changes in delivery and content. However, the effects of implementation quality on longer‐term outcomes are unknown.

Over the past 30 years, researchers have documented effective, theory‐based programmes and practices that improve the health and well‐being of children. In order to produce measurable improvements in public health, such practices must be institutionalised; however, there are a number of barriers to translating what we know from science to what we do in practice. In the present article, we discuss a number of those barriers, including: cultural differences between those who espouse a public health, prevention science approach versus those who espouse a strengths‐building, health promotion approach; practical difficulties in documenting the evidence base for existing or newly developed programmes and practices; and inflexibility of standardised programmes and resulting insensitivity to local contexts. We discuss common ground between prevention and promotion perspectives and highlight emerging methods that facilitate the adoption of science‐based practice into community‐based services.

A growing body of literature provides evidence for the efficacy of workplace health promotion (WHP). However, little is known about effective dissemination strategies for WHP interventions. The purpose of this paper is to describe how a WHP agency in Zurich, Switzerland, used bulk mailings, information events, telephone marketing and free initial consultations for the large-scale geographic marketing of WHP services, with a focus on tobacco prevention (TP).

To analyze the number of companies responding positively to solicitation, examine the predictors of positive responses and explore the reasons for negative responses, the authors used both quantitative (e.g. a standardized questionnaire) and qualitative (telephone interviews) methods.

The results show that except for telephone marketing (69 percent), the success rates of dissemination activities were very low (3-9 percent). Predictors for a positive response were institutionalization of WHP, the representative’s personal concern about TP, and problems with environmental tobacco smoke within the company. The most prominent reason for a negative response was that the companies had already implemented TP measures by themselves and needed no further external support.

It is suggested that TP was the wrong emphasis for a WHP program to be disseminated at that particular time, because a law on protection from passive smoking was introduced in Switzerland shortly afterwards.

The study examines dissemination strategies under real-life consulting conditions. It builds on on a large sample of companies and uses both quantitative and qualitative research methods. It reports specific numbers and success rates of marketing activities and thereby contributes to the knowledge about an important issue for intervention planning in the field of WHP.

Empirically‐based programmes are the cornerstone of the prevention science field. Beyond curriculum content and design, several aspects of school‐based prevention and intervention programmes have been found to contribute to their effectiveness, including implementer training, programme fidelity and principal [head teacher] support. The current investigation examined whether the degree of heterogeneity among classroom members (ie. students' racial or ethnic backgrounds, students' neighbourhood socio‐economic status (SES), students' neighbourhood education level and students' neighbourhood immigrant status) influences the effectiveness of the Promoting Alternative Thinking Strategies (PATHS) social and emotional learning programme. The analyses found a relationship between the degree of classroom heterogeneity and students' pre‐test scores on social and emotional variables. Moreover, gender differences were evident on pre‐test scores, reflecting differential baselines. The findings for analysis on classroom heterogeneity as a moderator of the programme's effectiveness in improving students' social and emotional competence were mixed. Future research and policy implications are discussed related to advancing the field and ensuring culturally relevant evidence‐based programming.
