Evidence-based approaches to dissemination and diffusion of physical activity interventions

Developing a Dissemination Model to Improve Intervention Reach among West Virginia Youth Smokers

The not-on-tobacco program is an evidence-based teen smoking cessation program adopted by the American Lung Association (ALA). Although widely disseminated nationally via ALA Master Trainers, in recent years, adoption and implementation of the N-O-T program in West Virginia (WV) has slowed. WV, unfortunately, has one of the highest smoking rates in the US. Although it is a goal of public health science, dissemination of evidence-based interventions is woefully understudied. The present manuscript reviews a theoretical model of dissemination of the not-on-tobacco program in WV. Based on social marketing, diffusion of innovations, and social cognitive theories, the nine-phase model incorporates elements of infrastructure development, accountability, training, delivery, incentives, and communication. The model components as well as preliminary lessons learned from initial implementation are discussed.

Translating Guidelines for the Diagnosis and Management of Sports-Related Concussion Into Practice

Sports injuries are a significant clinical and public health concern. There is a growing call to improve the translation of available evidence-based and expert-informed sports injury prevention interventions into sustained use in practice by physicians and others (eg, athletic trainers, coaches, and parents) who care for injured athletes. This article provides a brief overview of the current sport injury prevention implementation literature before focusing specifically on the translation of guidelines (including consensus and position statements) developed to assist physicians and others diagnose and manage athletes with sport-related concussion and the associated return-to-play decisions. The outcomes of more than 20 published studies indicate that physician, athletic trainer, coach, parent, and athlete knowledge, use of, and compliance with sport-related concussion guidelines are limited. More concerted, coordinated, and theory-informed efforts are required to facilitate the widespread dissemination, translation, and implementation of such guidelines. An example is provided of how implementation drivers could be used to inform the development of a comprehensive, multilevel implementation strategy targeting the individual, organizational, and system-level changes necessary to support the translation of available sport-related concussion guidelines in both the clinical and sports settings.

The researchers have left the building: what contributes to sustaining school-based interventions following the conclusion of formal research support?

BACKGROUND

This study examined the sustainability of New Moves, a school-based program aimed at decreasing weight-related problems in adolescent girls. The National Cancer Institute recognizes New Moves as a research-tested intervention program that produced positive behavioral and psychosocial outcomes.

METHODS

Ten schools participated in the sustainability study. Teachers completed a survey and interview, and research staff observed 1 physical education (PE) class within 2 years of the study's completion. Qualitative data were grouped by themes. Frequencies were calculated using quantitative data.

RESULTS

All schools continued all-girls PE classes using New Moves components following the study period. Fewer schools continued the nutrition and social support classroom modules and individual coaching sessions while no schools continued lunch get-togethers. Program components were sustained in both New Moves intervention schools and control schools.

CONCLUSIONS

Programs are most likely to be sustained if they (1) fit into the current school structure, (2) receive buy-in by teachers, and (3) require minimal additional funds or staff time. Providing control schools with minimal training and intervention resources was sufficient to continue program components if staff perceived the program was important for students' health and compatible within the school's existing infrastructure.

Promoting youth physical activity in rural southern communities: practitioner perceptions of environmental opportunities and barriers

PURPOSE

Research on youth physical activity has focused on urban areas. Rural adolescents are more likely to be physically inactive than urban youth, contributing to higher risk of obesity and chronic diseases. Study objectives were to: (1) identify perceived opportunities and barriers to youth physical activity within a rural area and (2) identify rural community characteristics that facilitate or inhibit efforts to promote youth physical activity.

METHODS

Thirty in-depth interviews were conducted with expert informants in 2 rural southern US counties. Interviewees were recruited from diverse positions across multiple sectors based on their expert knowledge of community policies and programs for youth physical activity.

FINDINGS

Informants saw ball fields, natural amenities, and school sports as primary resources for youth physical activity, but they were divided on whether opportunities were abundant or scarce. Physical distance, social isolation, lack of community offerings, and transportation were identified as key barriers. Local social networks facilitated political action and volunteer recruitment to support programs. However, communities often lacked human capital to sustain initiatives. Racial divisions influenced perceptions of opportunities. Despite divisions, there were also examples of pooling resources to create and sustain physical activity opportunities.

CONCLUSIONS

Developing partnerships and leveraging local resources may be essential to overcoming barriers for physical activity promotion in rural areas. Involvement of church leaders, school officials, health care workers, and cooperative extension is likely needed to establish and sustain youth rural physical activity programs. Allocating resources to existing community personnel and volunteers for continuing education may be valuable.

Dissemination of an evidence-based telephone-delivered lifestyle intervention: factors associated with successful implementation and evaluation

To inform wider-scale dissemination efforts of health behavior change interventions, we need to better understand factors associated with successful implementation and evaluation in nonresearch settings. Using the experience of the Optimal Health Program dissemination (OHP), a 12-month evidence-based telephone-delivered intervention for physical activity, healthy eating, and weight loss, we provide a detailed account according to the reach, efficacy/effectiveness, adoption, implementation, and maintenance (RE-AIM) framework of the supports that were needed to facilitate the delivery and evaluation of the program in an applied community-based primary health care setting. Substantial initial research support including development of data collection procedures, staff training in intervention protocols, and ongoing support for fidelity of data collection and intervention delivery, as well as evaluation and reporting of outcomes was required. The RE-AIM framework can highlight common elements that will require attention from researchers to promote success of programs in applied settings.

Results from the dissemination of an evidence-based telephone-delivered intervention for healthy lifestyle and weight loss: the Optimal Health Program

Despite proven efficacy, there are few published evaluations of telephone-delivered interventions targeting physical activity, healthy eating, and weight loss in community dissemination contexts. This study aims to evaluate participant and program outcomes from the Optimal Health Program, a telephone-delivered healthy lifestyle and weight loss program provided by a primary health care organization. Dissemination study used a single-group, repeated measures design; outcomes were assessed at 6-month (mid-program; n = 166) and 12-month (end of program; n = 88) using paired analyses. The program reached a representative sample of at-risk, primary care patients, with 56 % withdrawing before program completion. Among completers, a statistically significant improvement between baseline and end of program was observed for weight [mean change (SE) -5.4 (7.0) kg] and waist circumference [-4.8 (9.7) cm], underpinned by significant physical activity and dietary change. Findings suggest that telephone-delivered weight loss and healthy lifestyle programs can provide an effective model for use in primary care settings, but participant retention remains a challenge.

Which factors play a role in Dutch health promotion professionals’ decision to recruit actively primary schools to use a web-based smoking prevention programme?

Background

Municipal Health Promotion Organisations (MHPOs) play an important role in promoting and disseminating prevention programmes, such as smoking prevention programmes, in schools. This study identifies factors that may facilitate or hinder MHPOs’ willingness to recruit actively primary schools to use a smoking prevention programme.

Methods

In 2011, 31 Dutch MHPOs were invited to recruit schools to use a smoking prevention programme. All MHPO employees involved in smoking prevention activities (n = 68) were asked to complete a questionnaire assessing psychological factors and characteristics of their organisation that might affect their decision to be involved in active recruitment of schools. T-tests and multivariate analysis of variance assessed potential differences in psychological and organisational factors between active and non-active recruiters.

Results

A total of 45 professionals returned the questionnaire (66.2%). Active recruiters (n = 12) had more positive attitudes (p = 0.02), higher self-efficacy expectations (p < 0.01) and formulated more plans (p < 0.01) to recruit primary schools, compared with non-active recruiters. Organisational factors did not discriminate between active and non-active recruiters.

Conclusions

Primarily psychological factors seem to be associated with MHPOs’ decision to recruit schools actively. This indicates that creating more positive attitude, self-efficacy beliefs and formation of plans may help in getting more MHPOs involved in active recruitment procedures.

Nutrition educator adoption and implementation of an experiential foods curriculum

OBJECTIVE

Describe changes in Nutrition Educator (NE) and Extension Agent (EA) motivation, self-efficacy, and behavioral capability over time after experiential food tasting curriculum training. Identify promoters of curriculum adoption, implementation, and future use.

DESIGN

Mixed methods design including surveys, lesson implementation reports, and interviews.

SETTING

New Mexico limited-resource schools.

PARTICIPANTS

Convenience sample of New Mexico Extension NE (n = 42) and their EA supervisors (n = 21).

INTERVENTION

Three-hour curriculum training employing Social Cognitive Theory and Diffusion of Innovations.

MAIN OUTCOME MEASURES

Perceived change in motivation, self-efficacy, and behavioral capability from post-training through 8-month post-training; promoters and challenges to curriculum adoption, implementation, and future use.

ANALYSIS

Repeated-measures ANOVA analyzed perceived behavior change over time. Significance was set at P ≤ .05. Qualitative responses were categorized by theme.

RESULTS

Gains in NE motivation, self-efficacy, and behavioral capability were sustained at 8 months post-training. High adoption/implementation rates (79%) were attributed to strong implementation expectations, observational learning, experiential training elements, and perceived curriculum compatibility. Environmental factors including time constraints, personnel turnover, and scheduling conflicts proved challenging.

CONCLUSIONS AND IMPLICATIONS

Maximizing curriculum simplicity and compatibility and incorporating behavioral capability, observational learning, and expectations into training support adoption and use. Adaptations and techniques to problem-solve challenges should be provided to new curricula implementers.

Control of Allergic Rhinitis and Asthma Test (CARAT): dissemination and applications in primary care

Asthma frequently occurs in association with allergic rhinitis and a combined management approach has been suggested. The Control of Allergic Rhinitis and Asthma Test (CARAT) is the first questionnaire to assess control of both diseases concurrently. However, to have an impact on healthcare it needs to be disseminated and adopted. In this paper we discuss the dissemination of CARAT in different countries and its possible applications in primary care. At present, the adaptation of CARAT for use in different languages and cultures is being led by volunteer researchers and clinicians in 15 countries. Website and smartphone applications have been developed, and a free open model of distribution was adopted to contribute to the dissemination of CARAT. Examples of dissemination activities include distribution of leaflets and posters, educational sessions on the use of the questionnaire in the follow-up of patients, development of clinical studies, collaborations with professional organisations and health authorities, and the inclusion of CARAT in clinical guidelines. The adoption of innovations is an important challenge in healthcare today, and research on the degree of success of dissemination strategies using suitable methods and metrics is much needed. We propose that CARAT can be used in a range of settings and circumstances in primary care for clinical, research and audit purposes, within the overall aim of increasing awareness of the level of disease control and strengthening the partnership between patients and doctors in the management of asthma and rhinitis.

Sustained impact of community-based physical activity interventions: key elements for success

Background

Compelling evidence supports the cost effectiveness and potential impact of physical activity on chronic disease prevention and health promotion. Quality of evidence is one piece, but certainly not the sole determinant of whether public health interventions, physical activity focused or otherwise, achieve their full potential for impact. Health promotion at both population and community levels must progress beyond health intervention models that isolate individuals from social, environmental, and political systems of influence.

We offer a critical evaluation of lessons learned from two successful research initiatives to provide insights as to how health promotion research contributes to sustained impact. We highlight factors key to success including the theoretical and methodological integration of: i) a social ecological approach; ii) participatory action research (PAR) methods; and iii) an interdisciplinary team.

Methods

To identify and illustrate the key elements of our success we layered an evaluation of steps taken atop a review of relevant literature.

Results

In the school-based case study (Action Schools! BC), the success of our approach included early and sustained engagement with a broad cross-section of stakeholders, establishing partnerships across sectors and at different levels of government, and team members across multiple disciplines. In the neighbourhood built environment case study, the three domains guided our approach through study design and team development, and the integration of older adults’ perspectives into greenway design plans. In each case study we describe how elements of the domains serve as a guide for our work.

Conclusion

To sustain and maximize the impact of community-based public health interventions we propose the integration of elements from three domains of research that acknowledge the interplay between social, environmental and poilitical systems of influence. We emphasize that a number of key factors determine whether evidence from public health interventions in school and built environment settings is applied in practice and policy sectors. These include relationship building at individual, community, and societal levels of the social ecological model, using participatory action research methods, and involving an engaged and committed interdisciplinary team.

Evaluation of a workplace intervention to promote commuter cycling: a RE-AIM analysis

Background

Originating from the interdisciplinary collaboration between public health and the transportation field a workplace intervention to promote commuter cycling, ‘Bike to Work: cyclists are rewarded’, was implemented. The intervention consisted of two cycling contests, an online loyalty program based on earning ‘cycling points’ and the dissemination of information through folders, newsletters, posters and a website. The study purpose was to evaluate the dissemination efforts of the program and to gain insights in whether free participation could persuade small and middle-sized companies to sign up.

Methods

The RE-AIM framework was used to guide the evaluation. Two months after the start of the intervention a questionnaire was send to 4880 employees. At the end of the intervention each company contact person (n = 12) was interviewed to obtain information on adoption, implementation and maintenance.

Comparison analyses between employees aware and unaware of the program were conducted using independent-samples t-tests for quantitative data and chi-square tests for qualitative data. Difference in commuter cycling frequency was assessed using an ANOVA test. Non-parametric tests were used for the comparison analyses between the adopting and non-adopting companies.

Results

In total seven of the twelve participating companies adopted the program and all adopting companies implemented all intervention components. No significant differences were found in the mean number of employees (p = 0.15) or in the type of business sector (p = 0.92) between adopting and non-adopting companies. Five out of seven companies had the intention to continue the program. At the individual level, a project awareness of 65% was found. Employees aware of the program had a significantly more positive attitude towards cycling and reported significantly more commuter cycling than those unaware of the program (both p < 0.001). Participation was mainly because of health and environmental considerations.

Conclusions

The results of the dissemination study are promising. The adoption and implementation rates indicate that the ‘Bike to Work: cyclists are rewarded’ program seems to be a feasible workplace intervention. At the individual level, a higher score of commuter cycling was found among the employees aware of the program. Nevertheless, more evidence regarding long term effectiveness and sustainability of the intervention is needed.

Exploring effective strategies for increasing the amount of moderate-to-vigorous physical activity children accumulate during recess: a quasi-experimental intervention study

BACKGROUND

Less than half of elementary children meet the physical activity recommendations of 30 to 60 minutes of moderate-to-vigorous physical activity (MVPA) on a daily basis. Recess provides the single biggest opportunity for children to accumulate MVPA. This study explored whether a teacher's social prompting to be active during recess alone and modeling of active recess-time games alone may increase the amount of MVPA children accumulate during recess.

METHODS

Three demographically matched schools were randomly assigned to receive a social prompting intervention, modeling intervention, or to serve as a comparison group. Pre- and postintervention physical activity data was collected utilizing accelerometers.

RESULTS

Compared with preintervention, MVPA during recess increased significantly in the social prompting group and decreased significantly in the modeling group. There were no significant changes in the comparison group. There was a significant interaction between time and intervention: pre- to postintervention change between interventions was significant for modeling versus comparison and modeling versus social prompting, but not for social prompting versus comparison.

CONCLUSIONS

Modeling was not an effective strategy for increasing MVPA during recess. Social prompting may be an effective strategy for increasing MVPA during recess. However, larger studies are needed to determine whether social prompting increases MVPA during recess. In light of evidence suggesting that MVPA is linked to lower obesity rates, and a substantial number of health and academic benefits, social prompting may be a useful strategy to further explore to address the childhood obesity epidemic, and improve students' health and academic outcomes.

Collaborative school-based obesity interventions: lessons learned from 6 southern districts

BACKGROUND

Although studies have shown that school-based obesity interventions can be effective, little is known about how to translate and implement programs into real-world school settings.

METHODS

Semistructured interviews were conducted in spring 2012 with 19 key informants who participated in a multifaceted childhood obesity intervention involving school nurses and wellness coordinators in 6 school districts and over 100 schools.

RESULTS

The intervention changed form according to the needs and interests of the school districts. Despite funding support, schools and nurses had little capacity to address childhood obesity without the help of the coordinator. Initiating programs at the beginning of the school year was particularly difficult for schools. Applying for grants from internal and external sources and assisting with planning and logistics for wellness activities were significant activities of the coordinator. Although some school personnel and families preferred a focus on wellness rather than obesity, those working with individual at-risk children and families found the experience especially gratifying.

CONCLUSIONS

In contrast to controlled studies, real-world implementation of obesity interventions in schools that are intended to create sustained change requires flexibility in intervention design, timing, and personnel. A single change agent focused on obesity-related activities was essential to success.

Effect of the planet health intervention on eating disorder symptoms in Massachusetts middle schools, 2005-2008

Introduction

The Planet Health obesity prevention curriculum has prevented purging and abuse of diet pills (disordered weight control behavior [DWCB]) in middle-school girls in randomized trials, but the effects of Planet Health on DWCB when implemented by schools under dissemination conditions are not known.

Methods

Massachusetts Department of Public Health and Blue Cross Blue Shield of Massachusetts disseminated Planet Health as part of the 3-year, Healthy Choices obesity prevention program in middle schools. We conducted an evaluation in 45 schools from fall 2005 to spring 2008. We gathered data from school staff to quantify intervention activities, and we gathered anonymous cross-sectional survey data from students on DWCB at baseline and Year 3 follow-up (n = 16,369). Multivariate logistic analyses with generalized estimating equations examined the effect of intervention activities on odds of students reporting DWCB at follow-up.

Results

Students in schools reaching a high number of youth with Planet Health lessons on reducing television viewing had lower odds of DWCB at follow-up (odds ratio [OR], 0.80 per 100 lesson-exposures; 95% confidence interval [CI], 0.74–0.85). In addition, reduced odds of DWCB at follow-up were found in schools with active staff teamwork (OR, 0.76; 95% CI, 0.66–0.86) and the presence of programs addressing television viewing goals with staff (OR, 0.38; 95% CI, 0.28–0.53).

Conclusion

Combined evidence from efficacy and effectiveness trials and now from dissemination research indicates that appropriately designed obesity prevention programs can achieve DWCB prevention on a large scale.

Planning the diffusion of a neck-injury prevention programme among community rugby union coaches

BACKGROUND

This paper describes the development of a theory-informed and evidence-informed, context-specific diffusion plan for the Mayday Safety Procedure (MSP) among community rugby coaches in regional New South Wales, Australia.

METHODS

Step 5 of Intervention Mapping was used to plan strategies to enhance MSP adoption and implementation.

RESULTS

Coaches were identified as the primary MSP adopters and implementers within a system including administrators, players and referees. A local advisory group was established to ensure context relevance. Performance objectives (eg, attend MSP training for coaches) and determinants of adoption and implementation behaviour (eg, knowledge, beliefs, skills and environment) were identified, informed by Social Cognitive Theory. Adoption and implementation matrices were developed and change-objectives for coaches were identified (eg, skills to deliver MSP training to players). Finally, intervention methods and specific strategies (eg, coach education, social marketing and policy and by-law development) were identified based on advisory group member experience, evidence of effective coach safety behaviour-change interventions and Diffusion of Innovations theory.

CONCLUSIONS

This is the first published example of a systematic approach to plan injury prevention programme diffusion in community sports. The key strengths of this approach were an effective researcher-practitioner partnership; actively engaging local sports administrators; targeting specific behaviour determinants, informed by theory and evidence; and taking context-related practical strengths and constraints into consideration. The major challenges were the time involved in using a systematic diffusion planning approach for the first time; and finding a planning language that was acceptable and meaningful to researchers and practitioners.

Physical activity implementation in schools: a 4-year follow-up

BACKGROUND

Action Schools! BC (AS!BC) is a comprehensive school-based model that utilizes a socioecologic approach to provide children with opportunities for physical activity at school in British Columbia.

PURPOSE

The hierarchy of factors associated with successful implementation of AS!BC was examined 4 years after it was scaled up.

METHODS

A cross-sectional multistage survey was administered to principals (n=133; 92% response rate) and Grade 4-7 teachers (n=587; 71% response rate) in 2008-2009. Constructs from the theories of organizational change, social cognitive theory and Rogers's diffusion of innovation model were used to examine characteristics of teachers and schools and attributes of the innovation associated with implementation. Multilevel mixed-effect logistic regression analyses were employed (analyzed in November 2011).

RESULTS

Self-efficacy, outcome expectation, training received, organizational climate/support, level of institutionalization, environmental influence, and attributes of the innovation were associated with implementation. In multivariate analyses, self-efficacy, training, and level of institutionalization remained significant (all p<0.05).

CONCLUSIONS

Demonstrating that an intervention "works" is only the first step toward promoting enhanced health at the population level. For wide-scale implementation, teacher-level self-efficacy and ongoing technical support to train teachers were important. At the school level, policies and guidelines provided a necessary, supportive environment for implementation.

Bridging research and practice: models for dissemination and implementation research

CONTEXT

Theories and frameworks (hereafter called models) enhance dissemination and implementation (D&I) research by making the spread of evidence-based interventions more likely. This work organizes and synthesizes these models by (1) developing an inventory of models used in D&I research; (2) synthesizing this information; and (3) providing guidance on how to select a model to inform study design and execution.

EVIDENCE ACQUISITION

This review began with commonly cited models and model developers and used snowball sampling to collect models developed in any year from journal articles, presentations, and books. All models were analyzed and categorized in 2011 based on three author-defined variables: construct flexibility, focus on dissemination and/or implementation activities (D/I), and the socioecologic framework (SEF) level. Five-point scales were used to rate construct flexibility from broad to operational and D/I activities from dissemination-focused to implementation-focused. All SEF levels (system, community, organization, and individual) applicable to a model were also extracted. Models that addressed policy activities were noted.

EVIDENCE SYNTHESIS

Sixty-one models were included in this review. Each of the five categories in the construct flexibility and D/I scales had at least four models. Models were distributed across all levels of the SEF; the fewest models (n=8) addressed policy activities. To assist researchers in selecting and utilizing a model throughout the research process, the authors present and explain examples of how models have been used.

CONCLUSIONS

These findings may enable researchers to better identify and select models to inform their D&I work.

Impact of a population based intervention to increase the adoption of multiple physical activity practices in centre based childcare services: a quasi experimental, effectiveness study

BACKGROUND

There is considerable scope to improve the delivery of practices that increase the physical activity of children in centre based childcare services. Few studies have reported the effectiveness of interventions to address this, particularly at a population level. The primary aim of this study was to describe the impact of an intervention to increase the adoption of multiple policies and practices to promote physical activity in centre based childcare services.

METHODS

A quasi experimental study was conducted in centre based childcare services (n =228) in New South Wales (NSW), Australia and involved a three month intervention to increase the adoption of eight practices within childcare services that have been suggested to promote child physical activity. Intervention strategies to support the adoption of practices included staff training, resources, incentives, follow-up support and performance monitoring and feedback. Randomly selected childcare services in the remainder of NSW acted as a comparison group (n = 164) and did not receive the intervention but may have been exposed to a concurrent NSW government healthy eating and physical activity initiative. Self reported information on physical activity policies, fundamental movement skills sessions, structured physical activity opportunities, staff involvement in active play and provision of verbal prompts to encourage physical activity, small screen recreation opportunities, sedentary time, and staff trained in physical activity were collected by telephone survey with childcare service managers at baseline and 18 months later.

RESULTS

Compared with the comparison area, the study found significantly greater increases in the prevalence of intervention services with a written physical activity policy, with policy referring to placing limits on small screen recreation, and with staff trained in physical activity. In addition, non-significant trends towards a greater increase in the proportion of intervention services conducting daily fundamental movement skill sessions, and such services having a physical activity policy supporting physical activity training for staff were also evident.

CONCLUSION

The intervention was effective in improving a number of centre based childcare service policies and practices associated with promoting child physical activity. Adoption of a broader range of practices may require more intensive and prolonged intervention support.

Translating the PLAYgrounds program into practice: a process evaluation using the RE-AIM framework

OBJECTIVES

To present the results of the process evaluation of the PLAYgrounds program, using the RE-AIM framework.

DESIGN

This study provides information regarding Reach, Adoption, Implementation and Maintenance.

METHODS

The PLAYgrounds program promotes increasing levels of physical activity in 6-12 years old children and was evaluated using the RE-AIM framework in 4 intervention schools. Data collection consisted of a physical activity questionnaire with children (n=765, Reach), SOPLAY observations (Implementation and Maintenance), questionnaires on the satisfaction of the implemented elements with teachers (n=59) and children (n=730, Implementation) and interviews for increased depth of information. In addition a simple counting of participating schools, describing of non-participating reasons and characteristics of the schools were documented (Adoption).

RESULTS

Reach of the target population (i.e. inactive children) was 60.7% (n=464) and the target population was representative for populations in low-SES neighbourhoods. The PLAYgrounds program was adopted by 4 schools (80%), at which 5 (from 7) program elements were successfully implemented. At 18 months follow-up, 3 of those 5 elements were completely maintained.

CONCLUSIONS

Adoption, Implementation, and Maintenance proved to be very high. Most likely due to the PLAYgrounds program being a complete intervention package that included financial, material, and staff support. Therefore, it is recommended to retain this high level of support when introducing the PLAYgrounds (or any other intervention) program in schools. In the future it would be recommended to evaluate the PLAYgrounds program on maintenance in schools where the key-person is employed at the school and funding is not available.

Promoting walking among office employees - evaluation of a randomized controlled intervention with pedometers and e-mail messages

BACKGROUND

The purpose of the study was to evaluate a 6-month intervention to promote office-employees' walking with pedometers and e-mail messages.

METHODS

Participants were recruited by 10 occupational health care units (OHC) from 20 worksites with 2,230 employees. Voluntary and insufficiently physically active employees (N = 241) were randomized to a pedometer (STEP, N = 123) and a comparison group (COMP, N = 118). STEP included one group meeting, log-monitored pedometer-use and six e-mail messages from OHC. COMP participated in data collection. Reach, effectiveness, adoption, implementation, maintenance (RE-AIM) and costs were assessed with questionnaires (0, 2, 6, 12 months), process evaluation and interviews (12 months).

RESULTS

The intervention reached 29% (N = 646) of employees in terms of participation willingness. Logistic regression showed that the proportion of walkers tended to increase more in STEP than in COMP at 2 months in "walking for transportation" (Odds ratio 2.12, 95%CI 0.94 to 4.81) and at 6 months in "walking for leisure" (1.86, 95%CI 0.94 to 3.69). Linear model revealed a modest increase in the mean duration of "walking stairs" at 2 and 6 months (Geometric mean ratio 1.26, 95%CI 0.98 to 1.61; 1.27, 0.98 to 1.64). Adoption and implementation succeeded as intended. At 12 months, some traces of the intervention were sustained in 15 worksites, and a slightly higher number of walkers in STEP in comparison with COMP was observed in "walking stairs" (OR 2.24, 95%CI 0.94 to 5.31) and in "walking for leisure" (2.07, 95%CI 0.99 to 4.34). The direct costs of the intervention were 43 Euros per participant.

CONCLUSIONS

The findings indicate only modest impact on some indicators of walking. Future studies should invest in reaching the employees, minimizing attrition rate and using objective walking assessment. TRIAL REGISTERATION: ISRCTN79432107.

Implementing organizational physical activity and healthy eating strategies on paid time: process evaluation of the UCLA WORKING pilot study

Integrating organizationally targeted wellness strategies into the routine conduct of business has shown promise in engaging captive audiences at highest risk of obesity and obesity-related health consequences. This paper presents a process evaluation of the implementation of the University of California, Los Angeles, Working Out Regularly Keeps Individuals Nurtured and Going (WORKING) pilot study. WORKING focuses on integrating physical activity and nutrition practices into workplace routine during non-discretionary paid work time. The purpose of the evaluation was to assess the quality of implementation and to understand factors that facilitated or hindered organizations' full uptake of the intervention. Fifteen worksites were randomly assigned to an intervention condition. Qualitative data were gathered through routine site visits and informant interviews conducted throughout each worksite's intervention period. Worksites were classified into one of four implementation success categories based on their level of adoption and maintenance of core intervention strategies. Six key factors emerged that were related to implementation success: site layout and social climate, wellness infrastructure, number and influence of Program Champions, leadership involvement, site innovation and creativity. This pilot study has informed the conduct of WORKING II; a cluster randomized controlled trial aimed at enrolling 60-70 worksites in Los Angeles County.

Physical education's role in public health: steps forward and backward over 20 years and HOPE for the future

The 1991 paper, "Physical education's role in public health" described the importance of physical education in addressing public health problems. On its 20th anniversary, this article reviews accomplishments in improving the health impact of physical education and identifies areas lacking progress. Major accomplishments include development of evidence-based programs, documentation of health and academic benefits of physical education, and acceptance of physical education as a public health resource. Additional work is needed to evaluate the uptake of evidence-based programs, improve national surveillance of physical education quantity and quality, establish stronger policies supporting active physical education, and achieve wide acceptance of public health goals within the physical education field. These opportunities constitute an agenda for actualizing the promise of health-optimizing physical education before the next 20 year anniversary.

Sustainability of the whole-community project '10,000 Steps': a longitudinal study

BACKGROUND

In the dissemination and implementation literature, there is a dearth of information on the sustainability of community-wide physical activity (PA) programs in general and of the '10,000 Steps' project in particular. This paper reports a longitudinal evaluation of organizational and individual sustainability indicators of '10,000 Steps'.

METHODS

Among project adopters, department heads of 24 public services were surveyed 1.5 years after initially reported project implementation to assess continuation, institutionalization, sustained implementation of intervention components, and adaptations. Barriers and facilitators of project sustainability were explored. Citizens (n = 483) living near the adopting organizations were interviewed to measure maintenance of PA differences between citizens aware and unaware of '10,000 Steps'. Independent-samples t, Mann-Whitney U, and chi-square tests were used to compare organizations for representativeness and individual PA differences.

RESULTS

Of all organizations, 50% continued '10,000 Steps' (mostly in cycles) and continuation was independent of organizational characteristics. Level of intervention institutionalization was low to moderate on evaluations of routinization and moderate for project saturation. The global implementation score (58%) remained stable and three of nine project components were continued by less than half of organizations (posters, street signs and variants, personalized contact). Considerable independent adaptations of the project were reported (e.g. campaign image). Citizens aware of '10,000 Steps' remained more active during leisure time than those unaware (227 ± 235 and 176 ± 198 min/week, respectively; t = -2.6; p < .05), and reported more household-related (464 ± 397 and 389 ± 346 min/week, respectively; t = -2.2; p < .05) and moderate-intensity-PA (664 ± 424 and 586 ± 408 min/week, respectively; t = -2.0; p < .05). Facilitators of project sustainability included an organizational leader supporting the project, availability of funding or external support, and ready-for-use materials with ample room for adaptation. Barriers included insufficient synchronization between regional and community policy levels and preference for other PA projects.

CONCLUSIONS

'10,000 Steps' could remain sustainable but design, organizational, and contextual barriers need consideration. Sustainability of '10,000 Steps' in organizations can occur in cycles rather than in ongoing projects. Future research should compare sustainability other whole-community PA projects with '10,000 Steps' to contrast sustainability of alternative models of whole-community PA projects. This would allow optimization of project elements and methods to support decisions of choice for practitioners.

What, why, and for whom: couples interventions: a deconstruction approach

This paper provides a commentary on the special series on universal processes and common factors in couple therapy (Halford & Snyder, this issue). The authors in this section share their insights, from varying perspectives, about what it is in couples therapy and relationship education programs that work, why they work, and for whom they work best. In so doing, these articles address specific elements of couples interventions--in effect, taking a couples approach apart in order to understand it better. However, as a collection, this section takes this approach to understanding one step further. It puts the elements back together again, making the process of couples therapy/relationship education more accessible and easier to customize based upon the couple, the presenting complaints, the therapist, and the context. The term "deconstruction" is used to describe how the specific elements of couples interventions are understood and reassembled in new, theoretical, and empirically validated ways. It is argued here that once it is understood that a couples intervention works, why it works, and for whom it works, we are able to individualize our approach to specific couples in an effort to make couples therapy better at improving relationships and keeping them improved.

The evolution of the steps program, 2003-2010: transforming the federal public health practice of chronic disease prevention

The Steps program, formerly known as Steps to a HealthierUS, was the first Centers for Disease Control and Prevention (CDC) program to support a community-based, integrated approach to chronic disease prevention. Steps interventions addressed both diseases and risk factors, focusing on the 3 leading causes of preventable deaths in the United States--tobacco use, poor nutrition, and physical inactivity--and the associated chronic conditions of asthma, diabetes, and obesity. When Steps shifted from interventions focused on individual health-risk behaviors to the implementation of policy, systems, and environmental changes, the program became an integral part of changing the way CDC addressed chronic disease prevention. In this article, we describe the shift in intervention strategies that occurred among Steps communities, the model that was developed as Steps evolved, common interventions implemented before and after the shift in approach, challenges experienced by Steps communities, and CDC programs that were modeled after Steps.

Telephone-delivered interventions for physical activity and dietary behavior change: an updated systematic review

CONTEXT

Telephone-delivered interventions targeting physical activity and dietary change have potential for broad population reach and thus have a role to play in addressing increasing rates of lifestyle-related chronic diseases. The purpose of this systematic review is to update the evidence for their potential to inform translation, including effectiveness in promoting maintenance, reporting on implementation, and costs.

EVIDENCE ACQUISITION

A structured search of PubMed, MEDLINE, and PsycINFO (January 2006 to April 2010) was conducted. Included studies reported on physical activity and/or dietary change in adults, delivered at least 50% of intervention contacts by telephone, and included a control group (except in dissemination studies). Detailed information on study design, intervention features, and behavioral outcomes was extracted, tabulated, and summarized.

EVIDENCE SYNTHESIS

Twenty-five studies (27 comparisons) were included: 16 for physical activity, two for diet, and seven for combined interventions. Twenty of 27 comparisons found evidence for initiation of behavior change (14 of 17 comparisons for physical activity; two of two for diet; four of eight for combined interventions). Ten of 25 studies evaluated post-intervention maintenance of change, with three reporting that maintenance was achieved for at least 50% of outcomes. Dissemination studies were rare (n=3), as were dose-response (n=2) and cost-effectiveness analyses (n=2).

CONCLUSIONS

Given the strength of evidence for telephone-delivered physical activity and dietary change interventions, greater emphasis on dissemination studies is warranted.

Eating disorders and exercise: a structural equation modelling analysis of a conceptual model

OBJECTIVE

Despite the well-established health benefits of physical activity, the role of exercise for eating disorders (ED) is controversial; thus dictating a need for a better understanding of the mechanisms of exercise and ED. The purpose of our study was to examine a conceptual model that hypothesizes regular exercise without psychological compulsion might impart beneficial effects for preventing and treating ED.

METHOD

University students (N = 539) completed self-report assessments of quality of life, exercise level, ED risk and exercise dependence symptoms. Structural equation modelling analysis was undertaken to examine the conceptual model's proposed relationships.

RESULTS

Mediation analysis and model comparison tests showed that the partially mediated model without the physical well-being latent construct fit the data best.

DISCUSSION

Our results provided initial support for the conceptual model by showing that the psychological benefits, but not the physical benefits, conveyed by exercise were associated with reduced ED risk.

Adopting an Evidence-Based Lifestyle Physical Activity Program: Dissemination Study Design and Methods

BACKGROUND: There is a scarcity of research studies that have examined academic-commercial partnerships to disseminate evidence-based physical activity programs. Understanding this approach to dissemination is essential because academic-commercial partnerships are increasingly common. Private companies have used dissemination channels and strategies to a degree that academicians have not, and declining resources require academicians to explore these partnerships. PURPOSE: This paper describes a retrospective case-control study design including the methods, demographics, organizational decision-making, implementation rates, and marketing strategy for Active Living Every Day (ALED), an evidence-based lifestyle physical activity program that has been commercially available since 2001. Evidence-based public health promotion programs rely on organizations and targeted sectors to disseminate these programs although relatively little is known about organizational-level and sector-level influences that lead to their adoption and implementation. METHODS: Cases (n=154) were eligible if they had signed an ALED license agreement with Human Kinetics (HK), publisher of the program's textbooks and facilitator manuals, between 2001 and 2008. Two types of controls were matched (2:2:1) and stratified by sector and region. Active controls (Control 1; n=319) were organizations that contacted HK to consider adopting ALED. Passive controls (Control 2; n=328) were organizations that received unsolicited marketing materials and did not initiate contact with HK. We used Diffusion of Innovations Theory (DIT) constructs as the basis for developing the survey of cases and controls. RESULTS: Using the multi-method strategy recommended by Dillman, a total of n=801 cases and controls were surveyed. Most organizations were from the fitness sector followed by medical, nongovernmental, governmental, educational, worksite and other sectors with significantly higher response rates from government, educational and medical sectors compared with fitness and other sectors, (p=0.02). More cases reported being involved in the decision to adopt ALED (p<0.0001). Data indicate that a low percentage of controls had ever heard of ALED despite repeated marketing and offering other types of physical activity programs and services. Finally, slightly over half of the adopters reported they had actually implemented the ALED program. CONCLUSION: Dissemination research requires new perspectives and designs to produce valid insights about the results of dissemination efforts. This study design, survey methods and theoretically-based questions can serve as a useful model for other evidence-based public health interventions that are marketed by commercial publishers to better understand key issues related to adoption and implementation of evidence-based programs.

A telephone-delivered physical activity and dietary intervention for type 2 diabetes and hypertension: does intervention dose influence outcomes?

PURPOSE

To examine associations of intervention dose with behavior change outcomes in a telephone counseling intervention for physical activity and dietary change.

DESIGN

Secondary analysis of intervention participants from a cluster-randomized controlled trial.

SETTING

Primary care practices in a disadvantaged community in Queensland, Australia.

SUBJECTS

Adult patients with type 2 diabetes or hypertension.

INTERVENTION

Patients (n = 228) received telephone counseling over a 12-month period. The initiation phase (1-4 months) consisted of up to 10 weekly or fortnightly calls; the maintenance-enhancement phase (5-12 months) consisted of up to eight monthly calls.

MEASURES

Intervention dose was defined as the number of calls completed in total and during each phase and was categorized into tertiles. Diet and physical activity were measured using validated self-report instruments.

ANALYSIS

Multivariate analyses of call completion and change in health behaviors.

RESULTS

Those completing a high number of calls were more likely to be female, white, older than 60 years, retired, and earning less than an average weekly Australian wage. Relative to low call completion, high completion during the maintenance-enhancement phase was associated with significantly greater (least squares mean [SE]) behavioral improvement for the following: total fat intake as percentage of calories (-3.58% [.74%]), saturated fat intake (-2.51% [.51%]), fiber intake (4.23 [1.20] g), and moderate-to-vigorous physical activity (187.82 [44.78] minutes).

CONCLUSION

Interventions of longer duration may be required to influence complex behaviors such as physical activity and fat and fiber intake.

Translating research to practice: using the RE-AIM framework to examine an evidence-based physical activity intervention in primary school settings

Although there has been an increase in the availability of effective, evidence-based physical activity interventions in school settings during the past decade, there is a paucity of published research focusing on the translation of these effective interventions into real-world practice. The purpose of this research was to examine the translatability of an existing school-based physical activity intervention. More specifically, this research sought to identify the barriers and facilitators in adopting, implementing, and maintaining a school-based physical activity intervention using RE-AIM as a theoretical evaluation framework. It was concluded that interventions that consider issues around complexity and compatibility with the school setting are more likely to be adopted, implemented, and maintained. It was recommended that future evaluations of physical activity interventions should not be limited to testing internal validity, but should consider external validity and ecological aspects, relevant to increasing dissemination in real-world settings.

The impact of disseminating the whole-community project '10,000 Steps': a RE-AIM analysis

Background

There are insufficient research reports on the wide-scale dissemination of effective whole-community physical activity (PA) programs. The purpose of this paper is to evaluate the impact of the wide-scale dissemination of '10,000 Steps', using the RE-AIM framework.

Methods

Dissemination efforts targeted a large region of Belgium and were concentrated on media strategies and peer networks of specific professional organizations, such as local health promotion services. Heads of department of 69 organizations received an on-line survey to assess project awareness, adoption, implementation and intended continuation of '10,000 Steps'. On the individual level, 755 citizens living in the work area of the organizations were interviewed for project awareness and PA levels. Measures were structured according to the RE-AIM dimensions (reach, effectiveness, adoption, implementation, maintenance). Independent sample t and chi-square tests were used to compare groups for representativeness at the organizational and individual level, and for individual PA differences.

Results

Of all organizations, 90% was aware of '10,000 Steps' (effectiveness - organizational level) and 36% adopted the project (adoption). The global implementation score was 52%. One third intended to continue the project in the future (maintenance) and 48% was still undecided. On the individual level, 35% of citizens were aware of '10,000 Steps' (reach). They reported significantly higher leisure-time PA levels than those not aware of '10,000 Steps' (256 ± 237 and 207 ± 216 min/week, respectively; t = -2.8; p < .005) (effectiveness - individual level). When considering representativeness, adoption of '10.000 Steps' was independent of most organizational characteristics, except for years of experience in PA promotion (7.6 ± 4.6 and 2.9 ± 5.9 years for project staff and non-project staff members, respectively; t = 2.79; p < 0.01). Project awareness in citizens was independent of all demographic characteristics.

Conclusions

'10,000 Steps' shows potential for wide-scale dissemination but a supportive linkage system seems recommended to encourage adoption levels and high quality implementation.

Designing for diffusion: how can we increase uptake of cancer communication innovations?

OBJECTIVE

The best innovations in cancer communication do not necessarily achieve uptake by researchers, public health and clinical practitioners, and policy makers. This paper describes design activities that can be applied and combined for the purpose of spreading effective cancer communication innovations.

METHODS

A previously developed Push-Pull-Infrastructure Model is used to organize and highlight the types of activities that can be deployed during the design phase of innovations. Scientific literature about the diffusion of innovations, knowledge utilization, marketing, public health, and our experiences in working to spread effective practices, programs, and policies are used for this purpose.

RESULTS

Attempts to broaden the reach, quicken the uptake, and facilitate the use of cancer communication innovations can apply design activities to increase the likelihood of diffusion. Some simple design activities hold considerable promise for improving dissemination and subsequent diffusion.

CONCLUSION

Augmenting current dissemination practices with evidence-based concepts from diffusion science, marketing science, and knowledge utilization hold promise for improving results by eliciting greater market pull.

PRACTICE IMPLICATIONS

Inventors and change agencies seeking to spread cancer communication innovations can experience more success by explicit consideration of design activities that reflect an expanded version of the Push-Pull-Infrastructure Model.

Disseminating research findings: what should researchers do? A systematic scoping review of conceptual frameworks

BACKGROUND

Addressing deficiencies in the dissemination and transfer of research-based knowledge into routine clinical practice is high on the policy agenda both in the UK and internationally.However, there is lack of clarity between funding agencies as to what represents dissemination. Moreover, the expectations and guidance provided to researchers vary from one agency to another. Against this background, we performed a systematic scoping to identify and describe any conceptual/organising frameworks that could be used by researchers to guide their dissemination activity.

METHODS

We searched twelve electronic databases (including MEDLINE, EMBASE, CINAHL, and PsycINFO), the reference lists of included studies and of individual funding agency websites to identify potential studies for inclusion. To be included, papers had to present an explicit framework or plan either designed for use by researchers or that could be used to guide dissemination activity. Papers which mentioned dissemination (but did not provide any detail) in the context of a wider knowledge translation framework, were excluded. References were screened independently by at least two reviewers; disagreements were resolved by discussion. For each included paper, the source, the date of publication, a description of the main elements of the framework, and whether there was any implicit/explicit reference to theory were extracted. A narrative synthesis was undertaken.

RESULTS

Thirty-three frameworks met our inclusion criteria, 20 of which were designed to be used by researchers to guide their dissemination activities. Twenty-eight included frameworks were underpinned at least in part by one or more of three different theoretical approaches, namely persuasive communication, diffusion of innovations theory, and social marketing.

CONCLUSIONS

There are currently a number of theoretically-informed frameworks available to researchers that can be used to help guide their dissemination planning and activity. Given the current emphasis on enhancing the uptake of knowledge about the effects of interventions into routine practice, funders could consider encouraging researchers to adopt a theoretically-informed approach to their research dissemination.

Informal training in staff networks to support dissemination of health promotion programs

PURPOSE

To study informal skill transfer via staff networks as a complement to formal training among afterschool childcare providers implementing a health promotion program.

DESIGN

Cross-sectional, sociometric network analysis.

SETTING

Boston Young Men's Christian Association (YMCA) afterschool programs implementing the iPLAY program.

PARTICIPANTS

All 91 staff members at 20 sites were eligible; 80 completed the survey (88% response rate).

MEASURES

At the network level, network density measured system-level connectedness. At the staff level, the independent variable was out degree, the number of individuals to whom respondents noted a program-related connection. The dependent variable was skill gains, the number of key implementation skills gained from the network.

ANALYSIS

We mapped the staff program-related social network. We utilized multiple linear regression to estimate the relationship between out degree and skill gains, and we adjusted for clustering of staff in sites.

RESULTS

Most staff (77%) reported gaining at least one skill from the network, but only 2% of potential network connections were established. The regression model showed that out degree (i.e., number of program-related contacts) was significantly associated with skill gains (beta = .48, p < .01) independent of other variables.

CONCLUSION

Informal skill transfer in staff networks may be a useful complement to formal training for implementation of health promotion programs, but informal skill transfer was likely underutilized in this network. Future research employing longitudinal and/or multisite data should examine these findings in greater detail.

Translating epidemiology into policy to prevent childhood obesity: the case for promoting physical activity in school settings

Childhood obesity is a serious public health problem resulting from energy imbalance (when the intake of energy is greater than the amount of energy expended through physical activity). Numerous health authorities have identified policy interventions as promising strategies for creating population-wide improvements in physical activity. This case study focuses on energy expenditure through physical activity (with a particular emphasis on school-based physical education [PE]). Policy-relevant evidence for promoting physical activity in youth may take numerous forms, including epidemiologic data and other supporting evidence (e.g., qualitative data). The implementation and evaluation of school PE interventions leads to a set of lessons related to epidemiology and evidence-based policy. These include the need to: (i) enhance the focus on external validity, (ii) develop more policy-relevant evidence on the basis of "natural experiments," (iii) understand that policy making is political, (iv) better articulate the factors that influence policy dissemination, (v) understand the real-world constraints when implementing policy in school environments, and (vi) build transdisciplinary teams for policy progress. The issues described in this case study provide leverage points for practitioners, policy makers, and researchers as they seek to translate epidemiology to policy.

A qualitative examination of perceived barriers and facilitators of physical activity for urban and rural youth

Many adolescents, both rural and urban, are not meeting the recommended levels for physical activity (PA). This investigation was designed to elicit socioecologic barriers and facilitators for PA in rural and urban middle school youth and their parents. Thirteen focus groups were conducted with 41 youth and 50 parents from eastern North Carolina. Distance, cost, crime/danger and television were mentioned as the primary barriers among parents. Youth mentioned school policies related to PA and crime/danger as the main PA barriers. The most salient facilitators discussed by parents were social/peer facilitators, facilities available and parental role modeling of PA. The primary facilitators mentioned by youth were social outlets and facilities available. Results indicate that intrapersonal, interpersonal, environmental and policy factors related to PA resonated with both youth and parents. Since rural and urban residents often perceive and interact differently with PA environments, more research is needed to properly adapt interventions.

ParticipACTION: Baseline assessment of the 'new ParticipACTION': A quantitative survey of Canadian organizational awareness and capacity

BACKGROUND

ParticipACTION is a Canadian physical activity (PA) communications and social marketing organization that was relaunched in 2007 after a six-year hiatus. This study assesses the baseline awareness and capacity of Canadian organizations that promote physical activity, to adopt, implement and promote ParticipACTION's physical activity campaign. The three objectives were: (1) to determine organizational awareness of both the 'original' and 'new' ParticipACTION; (2) to report baseline levels of three organizational capacity domains (i.e., to adopt, implement and externally promote physical activity initiatives); and, (3) to explore potential differences in those domains based on organizational size, sector and primary mandate.

METHODS

Organizations at local, provincial/territorial, and national levels were sent an invitation via email prior to the official launch of ParticipACTION to complete an on-line survey. The survey assessed their organization's capacity to adopt, implement and externally promote a new physical activity campaign within their organizational mandates. Descriptive statistics were employed to address the first two study objectives. A series of one-way analysis of variance were conducted to examine the third objective.

RESULTS

The response rate was 29.7% (268/902). The majority of responding organizations had over 40 employees and had operated for over 10 years. Education was the most common primary mandate, followed by sport and recreation. Organizations were evenly distributed between government and not-for-profits. Approximately 96% of respondents had heard of the 'original' ParticipACTION while 54.6% had heard of the 'new' ParticipACTION (Objective 1). Findings indicate good organizational capacity in Canada to promote physical activity (Objective 2) based on reported means of approximately 4.0 (on 5-point scales) for capacity to adopt, implement, and externally promote new physical activity campaigns. Capacity to adopt new physical activity campaigns differed by organizational sector and mandate, and capacity to implement differed by organizational mandate (Objective 3).

CONCLUSION

At baseline, and without specific details of the campaign, respondents believe they have good capacity to work with ParticipACTION. ParticipACTION may do well to capitalize on the existing strong organizational capacity components of leadership, infrastructure and 'will' of national organizations to facilitate the success of its future campaigns.

Why and how to improve physical activity promotion: lessons from behavioral science and related fields

This commentary highlights the importance of regular physical activity to the nation's health and discusses some of the major challenges and opportunities currently facing the field.

Implementation of Texas Senate Bill 19 to increase physical activity in elementary schools

In 2001, the 77th Texas legislature passed Senate Bill 19 requiring students in publicly funded elementary schools to participate in physical activity and schools to implement a coordinated school health program by September 1, 2007. We report on awareness of and adherence to Senate Bill 19 in a statewide sample of elementary schools and a subsample in two public health regions located along the Texas-Mexico border. Statewide, structured interviews with principals indicated high awareness of Senate Bill 19's requirements, but lower awareness of the need for parental involvement. Only 43% of Texas schools had adopted their coordinated program 1 year or less before the implementation deadline. Principals reported an average of 179 min of physical education per week, higher than the 135-min mandate. Among the subsample border schools, principals' physical activity reports were consistent with teacher records and student reports. Further, direct observation of physical education indicated that 50% of class time was spent in moderate and vigorous physical activity, meeting the level of physical activity intensity recommended by Healthy People 2010. The differences observed by public health regions included: more physical activity minutes in Region 10 (231 min compared to 217 min in Region 11); higher adoption of coordinated school health programs (92% compared to 75%); more district-level school health advisory committees (58% compared to 38%) and school-level school health advisory committees (83% compared to 25%); and a lower prevalence of obesity in 4th grade students (21% compared to 32%). Differences by region suggest that Senate Bill 19 is not being adhered to equally across the state, and some regions may require further support to increase implementation. Results underscore the importance of continued monitoring of enacted legislation, and that legislation for child health that focuses on school programs and policies requires funding and refinement to produce the intended effect.

Cost-effectiveness of a telephone-delivered intervention for physical activity and diet

BACKGROUND

Given escalating rates of chronic disease, broad-reach and cost-effective interventions to increase physical activity and improve dietary intake are needed. The cost-effectiveness of a Telephone Counselling intervention to improve physical activity and diet, targeting adults with established chronic diseases in a low socio-economic area of a major Australian city was examined.

METHODOLOGY/PRINCIPAL FINDINGS

A cost-effectiveness modelling study using data collected between February 2005 and November 2007 from a cluster-randomised trial that compared Telephone Counselling with a "Usual Care" (brief intervention) alternative. Economic outcomes were assessed using a state-transition Markov model, which predicted the progress of participants through five health states relating to physical activity and dietary improvement, for ten years after recruitment. The costs and health benefits of Telephone Counselling, Usual Care and an existing practice (Real Control) group were compared. Telephone Counselling compared to Usual Care was not cost-effective ($78,489 per quality adjusted life year gained). However, the Usual Care group did not represent existing practice and is not a useful comparator for decision making. Comparing Telephone Counselling outcomes to existing practice (Real Control), the intervention was found to be cost-effective ($29,375 per quality adjusted life year gained). Usual Care (brief intervention) compared to existing practice (Real Control) was also cost-effective ($12,153 per quality adjusted life year gained).

CONCLUSIONS/SIGNIFICANCE

This modelling study shows that a decision to adopt a Telephone Counselling program over existing practice (Real Control) is likely to be cost-effective. Choosing the 'Usual Care' brief intervention over existing practice (Real Control) shows a lower cost per quality adjusted life year, but the lack of supporting evidence for efficacy or sustainability is an important consideration for decision makers. The economics of behavioural approaches to improving health must be made explicit if decision makers are to be convinced that allocating resources toward such programs is worthwhile.

A multi-method process evaluation for a skin cancer prevention diffusion trial

This article describes process evaluation methods for the Pool Cool diffusion trial across 4 years. Pool Cool is a skin cancer prevention program that was found to improve behaviors and environments for sun protection at swimming pools in a randomized efficacy trial, which was followed by a national diffusion trial. The process evaluation focus shifted from measuring program satisfaction to assessing widespread program implementation, barriers and facilitators to implementation, and program maintenance and sustainability. Data collection methods include training surveys, database tracking, field coordinator activity logs, e-mails, surveys of parents, lifeguards and pool managers, and process evaluation interviews and site visits. The data revealed high levels of implementation of major program components when disseminated in the diffusion trial, including sun safety lessons, sun safety signs, and sunscreen use. This article describes program features and participant factors that facilitated local implementation, maintenance and sustainability across dispersed pools such as linkage agents, a packaged program, and adaptations of program elements.

Social and environmental factors associated with preschoolers' nonsedentary physical activity

The twofold purposes of the investigation were (a) to describe with direct observation data the physical activity behaviors and the accompanying social and environmental events of those behaviors for children in preschools and (b) to determine which contextual conditions were predictors of moderate to vigorous physical activity (MVPA) and nonsedentary physical activity (i.e., light activity + MVPA) for 3-, 4-, and 5-year-old children during their outdoor play. The results indicate that preschoolers' physical activity is characterized as sedentary in nature throughout their preschool day (i.e., 89% sedentary, 8% light activity, and 3% MVPA). During outdoor play periods, when children are most likely to be physically active, some contextual and social circumstances better predict their physical activity. Implications for policy makers, practitioners, and researchers are discussed.

Age differences in the relation of perceived neighborhood environment to walking

PURPOSE

The strength of the relationship of environment to physical activity may differ by age group. Older adults were expected to be more affected by environmental attributes than younger adults. The present study examined age-related differences in associations between perceived neighborhood environment and physical activity.

METHODS

Participants were 1623 adults aged 20 to 97 yr divided into five groups: ages 20-39, 40-49, 50-65, 66-75, and 76+. They were recruited from King County/Seattle, WA, neighborhoods selected to vary in land use and median income. Participants completed questionnaires about neighborhood environment attributes and walking for transportation and for leisure purposes. Neighborhood environment, within a 15- to 20-min walk from home, was measured on nine attributes with the validated Neighborhood Environment Walkability Scale questionnaire: residential density, proximity to nonresidential land uses, ease of access to nonresidential uses, street connectivity, walking/cycling facilities, esthetics, pedestrian traffic safety, crime safety, and proximity to recreation facilities. Participants reported frequency and duration of walking using the validated International Physical Activity Questionnaire and the Community Healthy Activities Model Program for Seniors. Partial correlations were computed, adjusting for demographics.

RESULTS

Walking for transportation was significantly related to multiple perceived neighborhood attributes in all age groups, although walking for leisure was not. Walking for transportation was significantly related to almost all neighborhood environment variables in the youngest age group. In contrast, only two environmental attributes, proximity to nonresidential uses (like shops) and recreation facilities, were moderately correlated with walking for transportation in the two oldest groups.

CONCLUSION

Communities need to be designed with many favorable environmental attributes to support walking for transportation among younger adults. Having nonresidential destinations and recreation facilities within walking distance may be among the most important attributes to support older adults' physical activity.
