Abstract

This dissertation applied a variety of methods under the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework and provided a valuable and relevant contribution to the field of the dissemination and implementation (D&I) science. In the first study, we applied the RE-AIM framework to evaluate interventions and summarize the literature on breastfeeding promotion programs on the Black population (Chapter 1). The study results provide meaningful findings by bridging the gap on the literature of reporting breastfeeding supporting services and resources available to ensure breastfeeding continuation, as well as the need for a better reporting on the individual-level and setting representativeness, cost-effectiveness of the interventions, sustainability elements and consistent report on fidelity and all measures of cost. In the second study, we applied the RE-AIM framework to understand decision-making preferences to adopt weight loss programs (Chapter 2). Using a discrete choice experiment where RE-AIM dimensions were used as choice attributes of a weight loss program. The interplay among the dimensions illuminates the complex nature of decision-making processes. Our results offer valuable insights to enhance the development and real-world application of weight loss interventions. In the third study (Chapter 3), an extension of the second study, we applied the RE-AIM framework as a quantitative measure to predict the validity of the RE-AIM outcomes within the context of a hypothetical weight loss program adoption. Our findings make a valuable addition and insights into enhancing interventions planning by stakeholders. As hypothesized, we have confirmed the predictive validity of the RE- AIM measures which v yielded significant differences for most of the RE-AIM outcomes. In the final study (Chapter 4), we used the system usability scale to assess the usability of the RE-AIM website to disseminate associated knowledge and resources of the D&I field and our finding showed the valuable source of information. Our results showed a significant improvement on the RE-AIM website usability with valuable improvements for the Dissemination Science filed (D&I), enabling a broader and more audience to effectively utilize the RE-AIM framework. Overall, this dissertation provided successful example applications of the RE-AIM framework across diverse study designs, highlighting its versatility in bridging the gap between research and practical implementation.
