Dissemination and implementation science for public health professionals: An overview and call to action
Brief fruit and vegetable messages integrated within a community physical activity program successfully change behaviour
BACKGROUND: Consumption of the recommended amounts of fruits and vegetables is associated with several health benefits. Currently less than 25% of the American population meets the minimum recommendation of five servings a day. In order to change this health behaviour, interventions should be based on theory and include community-wide social support. METHODS: A low intensity intervention was developed in which participants (n = 86) were randomly assigned to either the fruit and vegetable intervention (FVI) or standard control condition. The intervention was integrated into an ongoing community physical activity program and study participants were drawn from the sample of community members enrolled in the program. The FVI consisted of brief social cognitive theory-based messages delivered in nine weekly newsletters designed to improve participant outcome and self-efficacy expectations related to fruit and vegetable consumption. RESULTS: Participants in the FVI condition increased in their fruit and vegetable consumption by approximately one to one and one-third servings per day. The control condition showed no change in consumption. The effect of the intervention was enhanced when examined by the extent to which it was adopted by participants (i.e., the number of newsletters read). Those participants who read seven or more newsletters showed an increase of two servings per day. CONCLUSION: This intervention was effective at improving fruit and vegetable consumption among adults. Minimal interventions, such as newsletters, have the ability to reach large audiences and can be integrated into ongoing health promotion programs. As such, they have potential for a strong public health impact
Group versus individual approach? A meta-analysis of the effectiveness of interventions to promote physical activity
The purpose of the study was to conduct a meta-analysis to empirically compare the relative merits of different contexts typically employed in the physical activity intervention literature for five categories of outcomes: adherence, social interaction, quality of life, physiological effectiveness, and functional effectiveness. \ud
Four contexts were examined: home-based programmes not involving contact from researchers or health-care professionals, home-based programmes that involved some contact, standard exercise classes, and exercise classes where group-dynamics principles were used to increase cohesiveness (‘true groups’). Standard literature searches produced 44 relevant studies containing 214 effect sizes. Results revealed a common trend across dependent variables; exercising in a true group was superior to exercising in a standard exercise class, which in turn, did not differ from exercising at home with contact. Furthermore, exercising at home with contact was superior to exercising at home without contact. These results have implications for practitioners in terms of the importance of contact and social support in physical activity interventions
Incentive Design to Enhance the Reach of Weight Loss Program
This study employed stated-preference methods to elicit individuals’ program participation preference towards different financial incentive attributes. The results of this study show promise for the use of carefully designed incentive programs to raise participation in weight loss programs. Results show that a fungible payment form is important for the incentive to be effective in reach (i.e., cash and grocery gift-cards are preferred over gym passes and waivers of insurance co-payments). Furthermore, immediate payment is preferred over delayed payment.Financial Incentives, Program Reach, Random Parameter Logit, Health Economics and Policy, F10, F13,
Obesity Interventions in Hispanic Americans Across the Lifespan: a systematic review using the RE-AIM framework
To determine the number and success of obesity treatment interventions for Hispanic populations that have been implemented in the past and examine the effectiveness of the interventions by looking at weight and or BMI change in the participants from the beginning to the end of the individual programs using a systematic review with the RE-AIM framework.https://digitalcommons.unmc.edu/surp2020/1011/thumbnail.jp
Comparing, contrasting, and integrating dissemination and implementation outcomes included in the RE-AIM and Implementation Outcomes Frameworks
As the field of dissemination and implementation science matures, there are a myriad of outcomes, identified in numerous frameworks, that can be considered across individual, organizational, and population levels. This can lead to difficulty in summarizing literature, comparing across studies, and advancing translational science. This manuscript sought to (1) compare, contrast, and integrate the outcomes included in the RE-AIM and Implementation Outcomes Frameworks (IOF) and (2) expand RE-AIM indicators to include relevant IOF dissemination and implementation outcomes. Cross
tabular comparisons were made between the constitutive definitions of each construct, across frameworks, to reconcile apparent discrepancies between approaches and to distinguish between implementation outcomes and implementation antecedents. A great deal of consistency was identified across approaches, including adoption (the intention, initial decision, or action to employ an evidence-based intervention), fidelity/implementation (the degree to which an intervention was delivered as intended),
organizational maintenance/sustainability (extent to which a newly implemented treatment is maintained or institutionalized), and cost. The IOF construct of penetration was defined as a higher-order construct that may encompass the reach, adoption, and organizational maintenance outcomes within RE-AIM. Within the IOF approach acceptability, appropriateness, and feasibility did not match constitutive definitions of dissemination or implementation but rather reflected theoretical antecedents of implementation outcomes. Integration of the IOF approach across RE-AIM indicators was successfully achieved by expanding the operational definitions of RE-AIM to include antecedents to reach, adoption, implementation, and organizational maintenance. Additional combined metrics were also introduced including penetration, individual level utility, service provider utility, organizational utility, and systemic utility. The expanded RE-AIM indicators move beyond the current approaches described within both the REAIM framework and IOF and provides additional planning and evaluation targets that can contribute to the scientific field and increase the translation of evidence into practice
A health/media literacy intervention improves adults’ interpretations of sugar-sweetened beverage advertising
Although excessive sugar-sweetened beverages (SSB) intake is linked to numerous adverse health consequences, media literacy interventions rarely address the influences of food and beverage marketing with a specific focus on adults. This randomized controlled trial study investigated (1) whether media literacy education modifies adults’ perceptions of SSB advertising and (2) whether changes are moderated by health literacy. Results from the multilevel mixed-effects regression analyses with the intention-to-treat last-observation-carried-forward method showed that compared to MoveMore (a matched-contact comparison condition), SIPsmartER (an intervention condition) participants significantly enhanced their skillsets across media literacy domains (i.e., authors/audiences, messages/meanings, representation/reality) between baseline and 6-month follow-up. Baseline health literacy status did not moderate media literacy outcomes. Both low and high health literate participants improved their outcomes, suggesting that this media literacy intervention benefited adults regardless of their health literacy level. Results demonstrate the importance of cultivating critical analyses and strengthening adults’ resistance toward SSB advertising
